Quarterly Report on Form 10-Q, including &#8220;Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations&#8221;
in Item 2, contains forward-looking statements that involve substantial risks and uncertainties. These forward-looking statements are
not historical fact but are based on current management expectations that involve substantial risks, uncertainties, and other factors,
some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed
in, or implied by, these forward-looking statements. Forward-looking statements relate to future events or our future financial performance.
We generally identify forward-looking statements by terminology such as &#8220;may,&#8221; &#8220;will,&#8221; &#8220;should,&#8221;
&#8220;expects,&#8221; &#8220;plans,&#8221; &#8220;anticipates,&#8221; &#8220;could,&#8221; &#8220;intends,&#8221; &#8220;target,&#8221;

or &#8220;continue&#8221; or the negative of these terms or other similar words. All statements, other than statements of historical
fact, are statements that could be deemed forward-looking statements including, but not limited to, any projections of revenue, gross
profit, earnings or loss, tax provisions, cash flows or other financial items; any statements of the plans, strategies or objectives
of management for future operations; any statements regarding current or future macroeconomic or industry-specific trends or events and
the impact of those trends and events on us or our financial performance; any statements regarding pending investigations, legal claims
or tax disputes; any statements of expectation or belief; and any statements of assumptions underlying any of the foregoing.</span></p>

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust

many of which were reversed by the end of the year when orders picked up and the overall business climate improved. Because the pandemic

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant
increase in shipments to U.S. ports, less cargo being shipped by air, a general shortage of containers, and domestic truck driver availability.
While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic have led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.</span></p>

accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced
recurring losses since its inception. Since inception, the Company has financed its activities principally through debt and equity financing,
customer deposits and revenues from completed contracts. Management expects to incur additional losses and cash outflows in the foreseeable
future in connection with its operating activities. Management believes that the economic dislocations in the overall economy, in the
near term, will impact our revenues, losses and cash flows. There can be no assurance that the Company will be able to raise debt or
equity financing in sufficient amounts, when and if needed, on acceptable terms or at all. If results of operations for 2021 do not meet
management&#8217;s expectations, or additional capital is not available, management believes it has the ability to reduce certain expenditures.
The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors,
including the overall economy, market demand for the Company&#8217;s products and services, the quality of product development efforts,
management of working capital, and continuation of normal payment terms and conditions for purchase of the Company&#8217;s products.
The Company believes its cash balances and cash flow from operations will be insufficient to fund its operations for the next 12 months.
If the Company is unable to substantially increase revenues, reduce expenditures, or otherwise generate cash flows from operations, then
the Company will need to raise additional funding to continue as a going concern. The foregoing factors raise substantial doubt about
the Company&#8217;s ability to continue as a going concern for a period of one year from the date the financial statements are issued.
These condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.</span></p>

Company recorded goodwill in connection with its acquisition of Hydro Innovations, LLC in July 2014. Goodwill is reviewed for impairment
annually or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to
less than its carrying value. The Company performs a quantitative impairment test annually on December 31 by comparing the fair value
of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount,
goodwill is considered not impaired. An impairment charge would be recognized for the amount by which the carrying amount exceeds the
reporting unit&#8217;s fair value. The Company determined that it has one reporting unit.</span></p>

the revenue standard, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the
customer. Most of the Company&#8217;s contracts contain multiple performance obligations that include engineering and technical services
as well as the delivery of a diverse range of climate control system equipment and components, which can span multiple phases of a customer&#8217;s
project life cycle from facility design and construction to equipment delivery and system installation and start-up.</span></p>

contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance
obligation is satisfied. When there are multiple performance obligations within a contract, the Company allocates the transaction price
to each performance obligation based on standalone selling price. When estimating the selling price, the Company uses various observable
inputs. The best observable input is the Company&#8217;s actual selling price for the same good or service, however, this input is generally
not available for the Company&#8217;s contracts containing multiple performance obligations. For engineering services, the Company estimates
the standalone selling price by reference to certain physical characteristics of the project, such as facility size and mechanical systems
involved, which are indicative of the scope and complexity of the mechanical engineering services to be provided. For equipment sales,
the standalone selling price is determined by forecasting the expected costs of the equipment and then adding an appropriate margin,
based on a range of acceptable margins established by management. Depending on the nature of the performance obligations, the Company
may use a combination of different methods and observable inputs if certain performance obligations have highly variable or uncertain
standalone selling prices. Once the selling prices are determined, the Company applies the relative values to the total contract consideration
and estimates the amount of the transaction price to be recognized as each performance obligation is fulfilled.</span></p>

Company recognizes revenue for the sale of goods when control transfers to the customer, which primarily occurs at the time of shipment.
The Company&#8217;s historical rates of return are insignificant as a percentage of sales and, as a result, the Company does not record
a reserve for returns at the time the Company recognizes revenue. The Company has elected to exclude from the measurement of the transaction
price all taxes (e.g., sales, use, value added, and certain excise taxes) that are assessed by a governmental authority in connection
with a specific revenue-producing transaction and collected by the Company from the customer. Accordingly, the Company recognizes revenue
net of sales taxes. The revenue and cost for freight and shipping is recorded when control over the sale of goods passes to the Company&#8217;s
customers.</span></p>

uncertainty, project financing concerns, and the licensing and qualification of our prospective customers, which are out of the Company&#8217;s
control, make it difficult for the Company to predict when it will recognize revenue on its remaining performance obligations. There
are risks that the Company may not realize the full contract value on customer projects in a timely manner or at all, and completion
of a customer&#8217;s cultivation facility project is dependent upon the customer&#8217;s ability to secure funding and real estate,
obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the time it takes
for customers to complete a project, which corresponds to when the Company is able to recognize revenue, is driven by numerous factors
including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business; (ii) the complexities
and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government delays in approving
licenses and permits due to lack of staff or the large number of pending applications, especially in states where there is no cap on
the number of cultivators; (iv) the customer&#8217;s need to obtain cultivation facility financing; (v) the time needed, and coordination
required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate control systems
can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system; (vii) the availability
of power; and (viii) delays that are typical in completing any construction project.</span></p>

was attributable to customer contracts for which the Company has only received an initial advance payment to cover the allocated value
of the Company&#8217;s engineering services (&#8220;engineering only paid contracts&#8221;). There is the risk that the equipment portion
of these engineering only paid contracts will not be completed or will be delayed. These reasons include the customer being dissatisfied
with the quality or timeliness of the Company&#8217;s engineering services, delay or abandonment of the project because of the customer&#8217;s
inability to obtain project financing or licensing, or other reasons such as a challenging business climate including an overall post-Covid-19
economic disruption or change in business direction. After the customer has made an advance payment for a portion of the equipment to
be delivered under the contract (&#8220;partial equipment paid contracts&#8221;), the Company is typically better able to estimate the
timing of revenue recognition since the risks and delays associated with licensing, permitting and project funding are typically mitigated
once the initial equipment payment is received. There is significant uncertainty regarding the timing of the Company&#8217;s recognition
of revenue on its remaining performance obligations, and there is no certainty that these will result in actual revenues. The backlog

Company recognizes the cost resulting from all share-based compensation arrangements, including stock options, restricted stock awards
and restricted stock units that the Company grants under its equity incentive plan in its condensed consolidated financial statements
based on their grant date fair value. The expense is recognized over the requisite service period or performance period of the award.
Awards with a graded vesting period based on service are expensed on a straight-line basis for the entire award. Awards with performance-based
vesting conditions, which require the achievement of a specific company financial performance goal at the end of the performance period
and required service period, are recognized over the performance period. Each reporting period, the Company reassesses the probability
of achieving the respective performance goal. If the goals are not expected to be met, no compensation cost is recognized and any previously
recognized amount recorded is reversed. If the award contains market-based vesting conditions, the compensation cost is based on the
grant date fair value and expected achievement of market condition and is not subsequently reversed if it is later determined that the
condition is not likely to be met or is expected to be lower than initially expected.</span></p>

grant date fair value of stock options is based on the Black-Scholes Option Pricing Model (the &#8220;Black-Scholes Model&#8221;). The

risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected term of the option. The Company
determines the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility,
expected term or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, the Company may
use different assumptions for options granted throughout the year. During the nine months ended September 30, 2021, the valuation assumptions

also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#8217;s
own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis,

over a similar term an amount equal to the lease payments in a similar economic environment. Since the discount rate is not implicit
in the lease agreement, we utilized an estimated incremental borrowing rate provided by the Company&#8217;s depository bank.</span></p>

The sublease commenced on April 30, 2021 and will continue on a month-to-month basis until either party gives 30-days&#8217; notice.
Unless 30-days&#8217; notice is provided sooner, this sublease will end upon termination of the Company&#8217;s Lease Agreement with
its current landlord.

The Sublessor
is also responsible for its prorated share of utilities and other related costs. This new sublease does not change the Company&#8217;s
legal relationship or financial obligations with its landlord. The Company continues to be responsible for all the remaining financial
obligations under its existing lease with the landlord. Accordingly, entering into the new sublease did not impact the carrying value
of the Company&#8217;s operating lease right of use asset or operating lease liability. Moreover, after an initial two-month transitional
period, the rental rate per square foot under the new sublease is identical to the rental rate per square foot for the Company&#8217;s
existing lease with its landlord which indicates that there is no impairment to the carrying value of the Company&#8217;s operating lease
right of use asset.</span></p>

Company must assess the likelihood that its net deferred tax assets will be recovered from future taxable income, and to the extent the
Company believes that recovery is not likely, the Company establishes a valuation allowance. Management&#8217;s judgment is required
in determining the Company&#8217;s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded
against the net deferred tax assets. The Company recorded a full valuation allowance as of September 30, 2021 and December 31, 2020.
Based on the available evidence, the Company believes it is more likely than not that it will not be able to utilize its net deferred
tax assets in the foreseeable future. The Company intends to maintain valuation allowances until sufficient evidence exists to support
the reversal of such valuation allowances. The Company makes estimates and judgments about its future taxable income that are based on
assumptions that are consistent with the Company&#8217;s plans. Should the actual amounts differ from the Company&#8217;s estimates,
the carrying value of the Company&#8217;s deferred tax assets could be materially impacted.</span></p>

CEA facility operators are facing multiple headwinds of high energy costs, issues about water usage and waste materials, and, in the
case of cannabis growing, increasingly rigorous quality standards and declining cannabis prices. To be competitive, among other things,
our customers must develop innovative ways to meet the demands of their business and reduce energy costs, 90% of which is typically related
to their HVACD (50%) and lighting systems (40%). HVACD systems have historically been our focus, but in May of 2021, we announced an
initiative to expand our offerings to include most of the technical infrastructure of CEA facilities as well as maintenance services.
We often have the advantage of early engagement with our customers at the pre-build and construction phases and the corresponding opportunity
to build longer-term relationships with our existing customers and their facilities. Going forward, our plan is to leverage our existing
customer relationships and attempt to sell them additional products and services, thereby becoming &#8220;stickier&#8221; to our customers.</span></p>

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust
its operations as necessary. In early 2020 the Company took measures to reduce expenses in light of reduced orders and to preserve cash,
many of which were reversed by the end of the year when orders picked up and the overall business climate improved. Because the pandemic
continues in different parts of the world and in different ways in the United States, the Company continues to actively monitor its operations
and sales efforts and will make adjustments to its operations as necessary.</span></p>

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant
increase in shipments to U.S. ports, less cargo being shipped by air, a general shortage of containers, and domestic truck driver availability.
While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic has led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.</span></p>

the Company is continuing to navigate the financial, operational, and personnel challenges presented by the COVID-19 pandemic, the full
extent of the impact of COVID-19 on our operational and financial performance will depend on future developments, including the duration
and spread of the pandemic, the potential uncertainty related to and proliferation of new strains, and related actions taken by the U.S.
government, state and local government officials, and international governments to prevent disease spread, all of which are uncertain,
out of our control and cannot be predicted at this time.</span></p>

our dedicated engineering staff and our experience in over 800 projects including over 200 commercial facilities. Our 15 years in the
business has provided us a wide network of technology vendors from which we curate a selection of the best products. In addition, we
are the leading experts in applying the most challenging component of the technical infrastructure, the environmental controls, and we
have the knowledge required to engineer the interactions among the required components. A professional engineer (PE) license is not required
for the design of any other component in the facility and this engineering knowledge is one of our greatest strengths.</span></p>

the same. Among our objectives is to provide our customers with the most energy-efficient alternatives for their infrastructure. Energy
and resource efficiency is a high priority to us as engineers, and our most senior engineering staff hold the LEED (Leadership in Energy
and Environmental Design) credential. Our CEO previously helped build a cleantech company, has been involved in the cleantech industry
for over five years, and published a book on selling energy efficient technologies. We believe that we are in a position to lead the

controls of these facilities, which is a sophisticated engineering challenge due to the high humidity (latent heat) and heat load (sensible
heat) within these facilities. Not only are the loads high, but the environmental conditions within these facilities must be held closely
within limits that the facility&#8217;s managers request. Engineering to meet these limits requires us to consider all of the primary
components within the facility: lighting, irrigation, HVACD, fertigation, sensors, controls, CO<sub>2 </sub>dosing, monitoring and alarms,
facility physical limits such as power availability, and energy consumption. We believe that the expertise gained in working with many
of the primary components provides us with a uniquely well-informed view of the efficacy of the many primary components on offer in the
marketplace. We further believe that this knowledge will help us make wise choices of which products to pursue for strategic relationships,
and which providers to potentially merge with or acquire. For smaller component providers we believe that our publicly traded platform
and our existing sales and marketing reach will make us an attractive partner.</span></p>

an uplisting to a national exchange and a growth-supporting capital raise.</i> We are seeking an uplist to a national securities exchange
and plan to pursue a capital raise to provide us the resources to aggressively pursue the growth of the business and to fulfill our corporate
strategy. In 2019 our revenue grew 60% year-over-year, and we had our first-ever cash flow positive year. Despite the challenges brought
on by the COVID-19 pandemic in the first half of 2020, we believe that our revenue growth in 2019 and then in the Q3 2020 &#8211; Q3
2021 period validates our market opportunity and our business model. We also recognize that the costs of being a small public company
are substantial and require cash that could otherwise be used to sustain and grow the business. We believe that there is only one solution
to this issue: rapid revenue and margin growth. We believe that we have growth opportunities, but we are capital constrained and must
seek outside financing to pursue the growth we believe we can achieve.</span></p>

completion of a customer&#8217;s <i>new</i> build facility project is dependent upon the customer&#8217;s ability to secure funding and
real estate, obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the
time it takes for these customers to complete a new build project, which corresponds to when we are able to recognize revenue, is driven
by numerous factors including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business;
(ii) the complexities and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government
delays in approving licenses and permits due to lack of staff or the large number of pending applications, especially in states where
there is no cap on the number of cultivators; (iv) the customer&#8217;s need to obtain cultivation facility financing; (v) the time needed,
and coordination required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate
control systems can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system;
(vii) the availability of power; and (viii) delays that are typical in completing any construction project.</span></p>

has historically been the case for the Company at each quarter-end, there remains significant uncertainty regarding the timing of revenue
recognition of our backlog as of September 30, 2021. As of September 30, 2021, 12% of our backlog was attributable to customer contracts
for which we have only received an initial advance payment to cover our engineering services (&#8220;engineering only paid contracts&#8221;).
There are always risks that the equipment portion of our engineering only paid contracts will not be completed or will be delayed, which
could occur if the customer is dissatisfied with the quality or timeliness of our engineering services, there is a delay or abandonment
of the project due to the customer&#8217;s inability to obtain project financing or licensing, or the customer determines not to proceed

condensed consolidated financial statements for the nine months ended September 30, 2021, have been presented on a going concern basis,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Our independent registered
public accounting firm included in its audit opinion on our consolidated financial statements for the year ended December 31, 2020, a
statement that there is substantial doubt as to our ability to continue as a going concern, and our consolidated financial statements
for the year ended December 31, 2020 were prepared assuming that we would continue as a going concern. We have determined that our ability
to continue as a going concern is dependent on continuing to generate sales and raising additional capital to fund our operations and
ultimately on generating future profitable operations. There can be no assurance that we will be able to raise sufficient additional
capital or eventually have positive cash flow from operations to address all of our cash flow needs. If we are not able to generate positive
cash flow from operations or find alternative sources of cash, our business and shareholders will be materially and adversely affected.
Based on our current assessment of our business, there is substantial doubt about our ability to continue as a going concern for a period
of one year from the date our condensed consolidated financial statements for the nine months ended September 30, 2021, are issued. Our
condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.</span></p>

Company is subject to a number of risks similar to those of other similar stage and situated companies, including general economic conditions;
its customers&#8217; operations and prospects for and ability to obtain project financing; market and business disruptions, that include
the effects of the COVID-19 pandemic and government response; dependence on key individuals; successful development, marketing and branding
of products; uncertainty of product development and generation of revenues; dependence on outside sources of financing; risks associated
with research, development; dependence on third-party suppliers and collaborators; protection of intellectual property; and competition
with larger, better-capitalized companies. Ultimately, the attainment of profitable operations is dependent on future events and obtaining
adequate financing to fulfill Company business development plans and activities and generating a level of revenues adequate to support

activities and financial results will depend on future developments, which are uncertain and cannot be predicted. Other factors that
will impact the Company&#8217;s ability to continue operations include the market demand for the Company&#8217;s products and services,
the ability to service its customers and prospects, potential contract cancellations, project scope reductions and project delays, the
Company&#8217;s ability to fulfill its backlog, the management of working capital, and the continuation of normal payment terms and conditions
for purchase of the Company&#8217;s products. The Company believes its cash balances and cash flow from operations will be insufficient

discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements,
which have been prepared in conformity with accounting principles generally accepted in the United States of America. Certain accounting
policies are particularly important to the understanding of our financial position and results of operations and require the application
of significant judgment by our management or can be materially affected by changes from period to period in economic factors or conditions
that are outside of our control. As a result, they are subject to an inherent degree of uncertainty. In applying these policies, management
uses their judgment to determine the appropriate assumptions to be used in the determination of certain estimates. Those estimates are
based on our historical operations, our future business plans and projected financial results, the terms of existing contracts, observance
of trends in the industry, information provided by our customers, and information available from other outside sources, as appropriate.
Actual results could materially differ from those estimates. Key estimates include: allocation of transaction prices to performance obligations
under contracts with customers, standalone selling prices, timing of expected revenue recognition on remaining performance obligations
under contracts with customers, valuation of intangible assets, valuation of equity-based compensation, valuation of deferred tax assets
and liabilities, warranty accruals, accounts receivable and inventory allowances, and legal contingencies.</span></p>

Inc. is an engineering and design company focused on selling environmental control and other technologies and services to the Controlled
Environment Agriculture (CEA) industry. We leverage our experience in this space to bring value-added technology solutions to our customers
that help improve their overall crop quality and yield, optimize energy and water efficiency, and satisfy evolving state and local construction
codes, permitting and regulatory requirements. In service of the CEA industry, our principal service and product offerings include:
(i) architectural design and licensed engineering of commercial scale thermodynamic systems specific to cultivation facilities, (ii)
liquid-based process cooling systems and other climate control systems, (iii) air handling equipment and systems, (iv) LED lighting,
benching and racking solutions for indoor cultivation, (v) automation and control devices, systems and technologies used for environmental,
lighting and climate control, and (vi) preventive maintenance services for CEA facilities. Our customers include commercial, state- and
provincial-regulated CEA growers in the U.S. and Canada and other international locations. Customers are those growers building new facilities
and those expanding or retrofitting existing facilities. Currently, our revenue stream is derived primarily from supplying our products,
services and technologies to commercial indoor facilities operating in the cannabis industry, ranging from several thousand to more than

COVID-19 pandemic has prompted national, regional, and local governments, including those in the markets that the Company operates in,
to implement preventative or protective measures to control its spread. As a result, there have been disruptions in business operations
around the world, with an impact on our business.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust
its operations as necessary. In early 2020 the Company took measures to reduce expenses in light of reduced orders and to preserve cash,
many of which were reversed by the end of the year when orders picked up and the overall business climate improved. Because the pandemic
continues in different parts of the world and in different ways in the United States, the Company continues to actively monitor its operations
and sales efforts and will make adjustments to its operations as necessary.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant
increase in shipments to U.S. ports, less cargo being shipped by air, a general shortage of containers, and domestic truck driver availability.
While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic have led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

the Company is continuing to navigate the financial, operational, and personnel challenges presented by the COVID-19 pandemic, the full
extent of the impact on our operational and financial performance will depend on future developments, including the duration and spread
of the pandemic, the potential uncertainty related to and proliferation of new strains, and related actions taken by the U.S. government,
state and local government officials, and international governments to prevent disease spread, all of which are uncertain, out of our
control and cannot be predicted at this time.&lt;/span&gt;&lt;/p&gt;

Form 10-Q and Rule 10-01 of Regulation S-X. Pursuant to these rules and regulations, certain information and note disclosures, normally
included in financial statements prepared in accordance with GAAP, have been condensed or omitted. In the opinion of management, all
adjustments (consisting of normal recurring items) considered necessary for a fair presentation have been included. Operating results
for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal
year ending December 31, 2021. The balance sheet as of December 31, 2020 has been derived from the audited financial statements at that
date but does not include all the information and footnotes required by GAAP for complete financial statements. For further information,
refer to the consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K for the year ended December
31, 2020. The notes to the unaudited condensed consolidated financial statements are presented on a going concern basis.&lt;/span&gt;&lt;/p&gt;

accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced
recurring losses since its inception. Since inception, the Company has financed its activities principally through debt and equity financing,
customer deposits and revenues from completed contracts. Management expects to incur additional losses and cash outflows in the foreseeable
future in connection with its operating activities. Management believes that the economic dislocations in the overall economy, in the
near term, will impact our revenues, losses and cash flows. There can be no assurance that the Company will be able to raise debt or
equity financing in sufficient amounts, when and if needed, on acceptable terms or at all. If results of operations for 2021 do not meet
management&#x2019;s expectations, or additional capital is not available, management believes it has the ability to reduce certain expenditures.
The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors,
including the overall economy, market demand for the Company&#x2019;s products and services, the quality of product development efforts,
management of working capital, and continuation of normal payment terms and conditions for purchase of the Company&#x2019;s products.
The Company believes its cash balances and cash flow from operations will be insufficient to fund its operations for the next 12 months.
If the Company is unable to substantially increase revenues, reduce expenditures, or otherwise generate cash flows from operations, then
the Company will need to raise additional funding to continue as a going concern. The foregoing factors raise substantial doubt about
the Company&#x2019;s ability to continue as a going concern for a period of one year from the date the financial statements are issued.
These condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

makes estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and
liabilities at the date of the financial statements and that affect the reported amounts of revenue and expenses during the reporting
period. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under
the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that
are not readily apparent from other sources. Actual results could differ from those estimates. Key estimates include: allocation of transaction
prices to performance obligations under contracts with customers, standalone selling prices, timing of expected revenue recognition on

income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average

Company recorded goodwill in connection with its acquisition of Hydro Innovations, LLC in July 2014. Goodwill is reviewed for impairment
annually or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to
less than its carrying value. The Company performs a quantitative impairment test annually on December 31 by comparing the fair value
of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount,
goodwill is considered not impaired. An impairment charge would be recognized for the amount by which the carrying amount exceeds the
reporting unit&#x2019;s fair value. The Company determined that it has one reporting unit.&lt;/span&gt;&lt;/p&gt;

the nine months ended September 30, 2021, the Company concluded that the projected impact of the COVID-19 pandemic on its sales, contract

issuance date, net of issuance costs, which is subsequently adjusted to redemption value (including the amount for dividends earned but
not yet declared or paid) at each balance sheet date if the instrument is currently redeemable or if it is probable that the instrument
will become redeemable.&lt;/span&gt;&lt;/p&gt;

Customers&lt;/i&gt; and all the related amendments (&#x201c;ASC 606&#x201d; or the &#x201c;revenue standard&#x201d;) to all contracts and elected
the modified retrospective method.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

the revenue standard, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the
customer. Most of the Company&#x2019;s contracts contain multiple performance obligations that include engineering and technical services
as well as the delivery of a diverse range of climate control system equipment and components, which can span multiple phases of a customer&#x2019;s
project life cycle from facility design and construction to equipment delivery and system installation and start-up.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

contract&#x2019;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance
obligation is satisfied. When there are multiple performance obligations within a contract, the Company allocates the transaction price
to each performance obligation based on standalone selling price. When estimating the selling price, the Company uses various observable
inputs. The best observable input is the Company&#x2019;s actual selling price for the same good or service, however, this input is generally
not available for the Company&#x2019;s contracts containing multiple performance obligations. For engineering services, the Company estimates
the standalone selling price by reference to certain physical characteristics of the project, such as facility size and mechanical systems
involved, which are indicative of the scope and complexity of the mechanical engineering services to be provided. For equipment sales,
the standalone selling price is determined by forecasting the expected costs of the equipment and then adding an appropriate margin,
based on a range of acceptable margins established by management. Depending on the nature of the performance obligations, the Company
may use a combination of different methods and observable inputs if certain performance obligations have highly variable or uncertain
standalone selling prices. Once the selling prices are determined, the Company applies the relative values to the total contract consideration
and estimates the amount of the transaction price to be recognized as each performance obligation is fulfilled.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company recognizes revenue for the sale of goods when control transfers to the customer, which primarily occurs at the time of shipment.
The Company&#x2019;s historical rates of return are insignificant as a percentage of sales and, as a result, the Company does not record
a reserve for returns at the time the Company recognizes revenue. The Company has elected to exclude from the measurement of the transaction
price all taxes (e.g., sales, use, value added, and certain excise taxes) that are assessed by a governmental authority in connection
with a specific revenue-producing transaction and collected by the Company from the customer. Accordingly, the Company recognizes revenue
net of sales taxes. The revenue and cost for freight and shipping is recorded when control over the sale of goods passes to the Company&#x2019;s
customers.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

Company also has performance obligations to perform certain engineering services that are satisfied over a period of time. Revenue is
recognized from this type of performance obligation as services are rendered based on the percentage completion towards certain specified
milestones.&lt;/span&gt;&lt;/p&gt;

the practical expedient in ASC 606-10-32-18, which the Company has elected, the Company does not adjust the promised amount of consideration
for the effects of a significant financing component since the Company expects, at contract inception, that the period between when the
Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.
Accordingly, the remaining performance obligations related to customer contracts does not consider the effects of the time value of money.&lt;/span&gt;&lt;/p&gt;

since the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs include
certain sales commissions and incentives, which are included in selling, general and administrative expenses, and are payable only when
associated revenue has been collected and earned by the Company.&lt;/span&gt;&lt;/p&gt;

Company does not have material amounts of contract assets since revenue is recognized as control of goods is transferred or as services
are performed. Contract liabilities consist of advance payments and deferred revenue.&lt;/span&gt;&lt;/p&gt;

performance obligations, or backlog, represents the aggregate amount of the transaction price allocated to the remaining obligations
that the Company has not performed under its customer contracts. The Company has elected not to use the optional exemption in ASC 606-10-50-14,
which exempts an entity from such disclosures if a performance obligation is part of a contract with an original expected duration of
one year or less. Accordingly, the information disclosed about remaining performance obligations includes all customer contracts, including
those with an expected duration of one year or less.&lt;/span&gt;&lt;/p&gt;

uncertainty, project financing concerns, and the licensing and qualification of our prospective customers, which are out of the Company&#x2019;s
control, make it difficult for the Company to predict when it will recognize revenue on its remaining performance obligations. There
are risks that the Company may not realize the full contract value on customer projects in a timely manner or at all, and completion
of a customer&#x2019;s cultivation facility project is dependent upon the customer&#x2019;s ability to secure funding and real estate,
obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the time it takes
for customers to complete a project, which corresponds to when the Company is able to recognize revenue, is driven by numerous factors
including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business; (ii) the complexities
and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government delays in approving
licenses and permits due to lack of staff or the large number of pending applications, especially in states where there is no cap on
the number of cultivators; (iv) the customer&#x2019;s need to obtain cultivation facility financing; (v) the time needed, and coordination
required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate control systems
can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system; (vii) the availability
of power; and (viii) delays that are typical in completing any construction project.&lt;/span&gt;&lt;/p&gt;

of September 30, 2021, the Company&#x2019;s remaining performance obligations, or backlog, was $&lt;span id="xdx_905_eus-gaap--RevenueRemainingPerformanceObligation_c20210930_pp0p0" title="Remaining performance obligations"&gt;9,881,000&lt;/span&gt;, of which $&lt;span id="xdx_90E_eus-gaap--RevenueRemainingPerformanceObligation_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--CustomerContractsMember_pp0p0" title="Remaining performance obligations"&gt;1,161,000&lt;/span&gt;, or &lt;span id="xdx_902_eus-gaap--RevenueRemainingPerformanceObligationPercentage_iI_pid_dp_uPure_c20210930_zfUHZeWvm788" title="Remaining performance obligations, percentage"&gt;12&lt;/span&gt;%,
was attributable to customer contracts for which the Company has only received an initial advance payment to cover the allocated value
of the Company&#x2019;s engineering services (&#x201c;engineering only paid contracts&#x201d;). There is the risk that the equipment portion
of these engineering only paid contracts will not be completed or will be delayed. These reasons include the customer being dissatisfied
with the quality or timeliness of the Company&#x2019;s engineering services, delay or abandonment of the project because of the customer&#x2019;s
inability to obtain project financing or licensing, or other reasons such as a challenging business climate including an overall post-Covid-19
economic disruption or change in business direction. After the customer has made an advance payment for a portion of the equipment to
be delivered under the contract (&#x201c;partial equipment paid contracts&#x201d;), the Company is typically better able to estimate the
timing of revenue recognition since the risks and delays associated with licensing, permitting and project funding are typically mitigated
once the initial equipment payment is received. There is significant uncertainty regarding the timing of the Company&#x2019;s recognition
of revenue on its remaining performance obligations, and there is no certainty that these will result in actual revenues. The backlog
at September 30, 2021, includes booked sales orders of $&lt;span id="xdx_906_eus-gaap--RevenueRemainingPerformanceObligation_iI_pp0p0_uUSD_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--OrderOrProductionBacklogMember_zQiH5yXcW5Ol" title="Remaining performance obligations"&gt;1,250,000&lt;/span&gt; from several customers that the Company does not expect to be realized
until late 2022. The Company believes the sales orders in this portion of our backlog have an elevated level of risk and may, ultimately,
be delayed or cancelled by our customers.&lt;/span&gt;&lt;/p&gt;

Company recognizes the cost resulting from all share-based compensation arrangements, including stock options, restricted stock awards
and restricted stock units that the Company grants under its equity incentive plan in its condensed consolidated financial statements
based on their grant date fair value. The expense is recognized over the requisite service period or performance period of the award.
Awards with a graded vesting period based on service are expensed on a straight-line basis for the entire award. Awards with performance-based
vesting conditions, which require the achievement of a specific company financial performance goal at the end of the performance period
and required service period, are recognized over the performance period. Each reporting period, the Company reassesses the probability
of achieving the respective performance goal. If the goals are not expected to be met, no compensation cost is recognized and any previously
recognized amount recorded is reversed. If the award contains market-based vesting conditions, the compensation cost is based on the
grant date fair value and expected achievement of market condition and is not subsequently reversed if it is later determined that the
condition is not likely to be met or is expected to be lower than initially expected.&lt;/span&gt;&lt;/p&gt;

grant date fair value of stock options is based on the Black-Scholes Option Pricing Model (the &#x201c;Black-Scholes Model&#x201d;). The
Black-Scholes Model requires judgmental assumptions including volatility and expected term, both based on historical experience. The
risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected term of the option. The Company
determines the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility,
expected term or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, the Company may
use different assumptions for options granted throughout the year. During the nine months ended September 30, 2021, the valuation assumptions
used to determine the fair value of each option award on the date of grant were: expected stock price volatility ranged from &lt;span id="xdx_906_eus-gaap--ShareBasedCompensationArrangementByShareBasedPaymentAwardFairValueAssumptionsExpectedVolatilityRate_pid_dp_uPure_c20210101__20210930__srt--RangeAxis__srt--MinimumMember_zJdPx4J7Uuwl"&gt;150.2&lt;/span&gt;&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;%

May 2021, the FASB issued ASU 2021-04, &lt;i&gt;Issuer&#x2019;s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified
Written Call Options. &lt;/i&gt;This guidance clarifies and reduces diversity in an issuer&#x2019;s accounting for modifications or exchanges
of freestanding equity-classified written call options due to a lack of explicit guidance in the FASB Codification. The guidance is effective
for interim and annual periods beginning after December 15, 2021. Early adoption is permitted. The guidance is to be applied prospectively
to modifications or exchanges occurring on or after the effective date. The Company anticipates that the adoption of this guidance will
not have a material impact on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

August 2020, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2020-06,
Debt &#x2014; Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging &#x2014; Contracts in Entity&#x2019;s
Own Equity (Subtopic 815-40) (&#x201c;ASU 2020-06&#x201d;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates
the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies
the derivative scope exception guidance pertaining to equity classification of contracts in an entity&#x2019;s own equity. The new standard
also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#x2019;s
own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis,
with early adoption permitted beginning on January 1, 2021. The Company early adopted ASU 2020-06 effective January 1, 2021. The early
adoption of ASU 2020-06 impacted the Company&#x2019;s accounting for the issuance of its Series B Redeemable Convertible Preferred Stock
as further discussed in &lt;i&gt;Note 8 Temporary Equity Series B Redeemable Convertible Preferred Stock&lt;/i&gt; below.&lt;/span&gt;&lt;/p&gt;

March 2020, the FAS issued ASU No. 2020-04 &#x201c;&lt;i&gt;Reference Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform
on Financial Reporting&#x201d; (&#x201c;ASU 2020-04&#x201d;).&lt;/i&gt; ASU 2020-04 provides optional guidance for a limited period of time to
ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments
are effective for the Company as of March 12, 2020 through December 31, 2022. The Company does not expect this ASU to have a material
impact on its consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

January 2020, the FASB issued ASU No. 2020-01, &lt;i&gt;Investments&#x2014;Equity Securities (Topic 321), Investments&#x2014;Equity Method and
Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)&#x2014;Clarifying the Interactions between Topic 321, Topic 323, and
Topic 815&lt;/i&gt; (a consensus of the Emerging Issues Task Force). This update clarifies whether an entity should consider observable transactions
that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative
and how to account for certain forward contracts and purchased options to purchase securities. For public entities, this guidance is
effective for fiscal years beginning after December 15, 2020. The Company does not expect this ASU to have a material impact on its consolidated
results of operations, cash flows and financial position. The adoption of this ASU has not had a material impact on the Company&#x2019;s
consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

December 2019, the FASB issued ASU 2019-12, &lt;i&gt;Income Taxes (Topic 740) &#x2013; Simplifying the Accounting for Income Taxes, &lt;/i&gt;which
simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also
improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12
is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted. The adoption of this ASU has not had a
material impact on the Company&#x2019;s consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have
a material impact on the financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated
to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/p&gt;

COVID-19 pandemic has prompted national, regional, and local governments, including those in the markets that the Company operates in,
to implement preventative or protective measures to control its spread. As a result, there have been disruptions in business operations
around the world, with an impact on our business.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust
its operations as necessary. In early 2020 the Company took measures to reduce expenses in light of reduced orders and to preserve cash,
many of which were reversed by the end of the year when orders picked up and the overall business climate improved. Because the pandemic
continues in different parts of the world and in different ways in the United States, the Company continues to actively monitor its operations
and sales efforts and will make adjustments to its operations as necessary.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant
increase in shipments to U.S. ports, less cargo being shipped by air, a general shortage of containers, and domestic truck driver availability.
While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic have led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.&lt;/span&gt;&lt;/p&gt;

the Company is continuing to navigate the financial, operational, and personnel challenges presented by the COVID-19 pandemic, the full
extent of the impact on our operational and financial performance will depend on future developments, including the duration and spread
of the pandemic, the potential uncertainty related to and proliferation of new strains, and related actions taken by the U.S. government,
state and local government officials, and international governments to prevent disease spread, all of which are uncertain, out of our
control and cannot be predicted at this time.&lt;/span&gt;&lt;/p&gt;

near term, will impact our revenues, losses and cash flows. There can be no assurance that the Company will be able to raise debt or
equity financing in sufficient amounts, when and if needed, on acceptable terms or at all. If results of operations for 2021 do not meet
management&#x2019;s expectations, or additional capital is not available, management believes it has the ability to reduce certain expenditures.
The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors,
including the overall economy, market demand for the Company&#x2019;s products and services, the quality of product development efforts,
management of working capital, and continuation of normal payment terms and conditions for purchase of the Company&#x2019;s products.
The Company believes its cash balances and cash flow from operations will be insufficient to fund its operations for the next 12 months.
If the Company is unable to substantially increase revenues, reduce expenditures, or otherwise generate cash flows from operations, then
the Company will need to raise additional funding to continue as a going concern. The foregoing factors raise substantial doubt about
the Company&#x2019;s ability to continue as a going concern for a period of one year from the date the financial statements are issued.
These condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.&lt;/span&gt;&lt;/p&gt;

makes estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and
liabilities at the date of the financial statements and that affect the reported amounts of revenue and expenses during the reporting
period. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under
the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that
are not readily apparent from other sources. Actual results could differ from those estimates. Key estimates include: allocation of transaction
prices to performance obligations under contracts with customers, standalone selling prices, timing of expected revenue recognition on
remaining performance obligations under contracts with customers, valuation of intangible assets, valuation of equity-based compensation,
valuation of deferred tax assets and liabilities, warranty accruals, accounts receivable and inventory allowances, and legal contingencies.&lt;/span&gt;&lt;/p&gt;

Company recorded goodwill in connection with its acquisition of Hydro Innovations, LLC in July 2014. Goodwill is reviewed for impairment
annually or more frequently when events or changes in circumstances indicate that fair value of the reporting unit has been reduced to
less than its carrying value. The Company performs a quantitative impairment test annually on December 31 by comparing the fair value
of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount,
goodwill is considered not impaired. An impairment charge would be recognized for the amount by which the carrying amount exceeds the
reporting unit&#x2019;s fair value. The Company determined that it has one reporting unit.&lt;/span&gt;&lt;/p&gt;

the revenue standard, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the
customer. Most of the Company&#x2019;s contracts contain multiple performance obligations that include engineering and technical services
as well as the delivery of a diverse range of climate control system equipment and components, which can span multiple phases of a customer&#x2019;s
project life cycle from facility design and construction to equipment delivery and system installation and start-up.&lt;/span&gt;&lt;/p&gt;

contract&#x2019;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance
obligation is satisfied. When there are multiple performance obligations within a contract, the Company allocates the transaction price
to each performance obligation based on standalone selling price. When estimating the selling price, the Company uses various observable
inputs. The best observable input is the Company&#x2019;s actual selling price for the same good or service, however, this input is generally
not available for the Company&#x2019;s contracts containing multiple performance obligations. For engineering services, the Company estimates
the standalone selling price by reference to certain physical characteristics of the project, such as facility size and mechanical systems
involved, which are indicative of the scope and complexity of the mechanical engineering services to be provided. For equipment sales,
the standalone selling price is determined by forecasting the expected costs of the equipment and then adding an appropriate margin,
based on a range of acceptable margins established by management. Depending on the nature of the performance obligations, the Company
may use a combination of different methods and observable inputs if certain performance obligations have highly variable or uncertain
standalone selling prices. Once the selling prices are determined, the Company applies the relative values to the total contract consideration
and estimates the amount of the transaction price to be recognized as each performance obligation is fulfilled.&lt;/span&gt;&lt;/p&gt;

The Company&#x2019;s historical rates of return are insignificant as a percentage of sales and, as a result, the Company does not record
a reserve for returns at the time the Company recognizes revenue. The Company has elected to exclude from the measurement of the transaction
price all taxes (e.g., sales, use, value added, and certain excise taxes) that are assessed by a governmental authority in connection
with a specific revenue-producing transaction and collected by the Company from the customer. Accordingly, the Company recognizes revenue
net of sales taxes. The revenue and cost for freight and shipping is recorded when control over the sale of goods passes to the Company&#x2019;s
customers.&lt;/span&gt;&lt;/p&gt;

Company also has performance obligations to perform certain engineering services that are satisfied over a period of time. Revenue is
recognized from this type of performance obligation as services are rendered based on the percentage completion towards certain specified
milestones.&lt;/span&gt;&lt;/p&gt;

Company offers assurance-type warranties for its products and products manufactured by others to meet specifications defined by the contracts

the practical expedient in ASC 606-10-32-18, which the Company has elected, the Company does not adjust the promised amount of consideration
for the effects of a significant financing component since the Company expects, at contract inception, that the period between when the
Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less.
Accordingly, the remaining performance obligations related to customer contracts does not consider the effects of the time value of money.&lt;/span&gt;&lt;/p&gt;

the practical expedient in ASC 340-40-25-4, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred
since the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs include
certain sales commissions and incentives, which are included in selling, general and administrative expenses, and are payable only when
associated revenue has been collected and earned by the Company.&lt;/span&gt;&lt;/p&gt;

performance obligations, or backlog, represents the aggregate amount of the transaction price allocated to the remaining obligations
that the Company has not performed under its customer contracts. The Company has elected not to use the optional exemption in ASC 606-10-50-14,
which exempts an entity from such disclosures if a performance obligation is part of a contract with an original expected duration of
one year or less. Accordingly, the information disclosed about remaining performance obligations includes all customer contracts, including
those with an expected duration of one year or less.&lt;/span&gt;&lt;/p&gt;

uncertainty, project financing concerns, and the licensing and qualification of our prospective customers, which are out of the Company&#x2019;s
control, make it difficult for the Company to predict when it will recognize revenue on its remaining performance obligations. There
are risks that the Company may not realize the full contract value on customer projects in a timely manner or at all, and completion
of a customer&#x2019;s cultivation facility project is dependent upon the customer&#x2019;s ability to secure funding and real estate,
obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the time it takes
for customers to complete a project, which corresponds to when the Company is able to recognize revenue, is driven by numerous factors
including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business; (ii) the complexities
and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government delays in approving
licenses and permits due to lack of staff or the large number of pending applications, especially in states where there is no cap on
the number of cultivators; (iv) the customer&#x2019;s need to obtain cultivation facility financing; (v) the time needed, and coordination
required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate control systems
can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system; (vii) the availability
of power; and (viii) delays that are typical in completing any construction project.&lt;/span&gt;&lt;/p&gt;

of September 30, 2021, the Company&#x2019;s remaining performance obligations, or backlog, was $&lt;span id="xdx_905_eus-gaap--RevenueRemainingPerformanceObligation_c20210930_pp0p0" title="Remaining performance obligations"&gt;9,881,000&lt;/span&gt;, of which $&lt;span id="xdx_90E_eus-gaap--RevenueRemainingPerformanceObligation_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--CustomerContractsMember_pp0p0" title="Remaining performance obligations"&gt;1,161,000&lt;/span&gt;, or &lt;span id="xdx_902_eus-gaap--RevenueRemainingPerformanceObligationPercentage_iI_pid_dp_uPure_c20210930_zfUHZeWvm788" title="Remaining performance obligations, percentage"&gt;12&lt;/span&gt;%,
was attributable to customer contracts for which the Company has only received an initial advance payment to cover the allocated value
of the Company&#x2019;s engineering services (&#x201c;engineering only paid contracts&#x201d;). There is the risk that the equipment portion
of these engineering only paid contracts will not be completed or will be delayed. These reasons include the customer being dissatisfied
with the quality or timeliness of the Company&#x2019;s engineering services, delay or abandonment of the project because of the customer&#x2019;s
inability to obtain project financing or licensing, or other reasons such as a challenging business climate including an overall post-Covid-19
economic disruption or change in business direction. After the customer has made an advance payment for a portion of the equipment to
be delivered under the contract (&#x201c;partial equipment paid contracts&#x201d;), the Company is typically better able to estimate the
timing of revenue recognition since the risks and delays associated with licensing, permitting and project funding are typically mitigated
once the initial equipment payment is received. There is significant uncertainty regarding the timing of the Company&#x2019;s recognition
of revenue on its remaining performance obligations, and there is no certainty that these will result in actual revenues. The backlog
at September 30, 2021, includes booked sales orders of $&lt;span id="xdx_906_eus-gaap--RevenueRemainingPerformanceObligation_iI_pp0p0_uUSD_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--OrderOrProductionBacklogMember_zQiH5yXcW5Ol" title="Remaining performance obligations"&gt;1,250,000&lt;/span&gt; from several customers that the Company does not expect to be realized
until late 2022. The Company believes the sales orders in this portion of our backlog have an elevated level of risk and may, ultimately,
be delayed or cancelled by our customers.&lt;/span&gt;&lt;/p&gt;

Company recognizes the cost resulting from all share-based compensation arrangements, including stock options, restricted stock awards
and restricted stock units that the Company grants under its equity incentive plan in its condensed consolidated financial statements
based on their grant date fair value. The expense is recognized over the requisite service period or performance period of the award.
Awards with a graded vesting period based on service are expensed on a straight-line basis for the entire award. Awards with performance-based
vesting conditions, which require the achievement of a specific company financial performance goal at the end of the performance period
and required service period, are recognized over the performance period. Each reporting period, the Company reassesses the probability
of achieving the respective performance goal. If the goals are not expected to be met, no compensation cost is recognized and any previously
recognized amount recorded is reversed. If the award contains market-based vesting conditions, the compensation cost is based on the
grant date fair value and expected achievement of market condition and is not subsequently reversed if it is later determined that the
condition is not likely to be met or is expected to be lower than initially expected.&lt;/span&gt;&lt;/p&gt;

grant date fair value of stock options is based on the Black-Scholes Option Pricing Model (the &#x201c;Black-Scholes Model&#x201d;). The
Black-Scholes Model requires judgmental assumptions including volatility and expected term, both based on historical experience. The
risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected term of the option. The Company
determines the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility,
expected term or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, the Company may
use different assumptions for options granted throughout the year. During the nine months ended September 30, 2021, the valuation assumptions

May 2021, the FASB issued ASU 2021-04, &lt;i&gt;Issuer&#x2019;s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified
Written Call Options. &lt;/i&gt;This guidance clarifies and reduces diversity in an issuer&#x2019;s accounting for modifications or exchanges
of freestanding equity-classified written call options due to a lack of explicit guidance in the FASB Codification. The guidance is effective
for interim and annual periods beginning after December 15, 2021. Early adoption is permitted. The guidance is to be applied prospectively
to modifications or exchanges occurring on or after the effective date. The Company anticipates that the adoption of this guidance will
not have a material impact on its consolidated financial statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

August 2020, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued Accounting Standards Update (&#x201c;ASU&#x201d;) 2020-06,
Debt &#x2014; Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging &#x2014; Contracts in Entity&#x2019;s
Own Equity (Subtopic 815-40) (&#x201c;ASU 2020-06&#x201d;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates
the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies
the derivative scope exception guidance pertaining to equity classification of contracts in an entity&#x2019;s own equity. The new standard
also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#x2019;s
own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis,
with early adoption permitted beginning on January 1, 2021. The Company early adopted ASU 2020-06 effective January 1, 2021. The early
adoption of ASU 2020-06 impacted the Company&#x2019;s accounting for the issuance of its Series B Redeemable Convertible Preferred Stock
as further discussed in &lt;i&gt;Note 8 Temporary Equity Series B Redeemable Convertible Preferred Stock&lt;/i&gt; below.&lt;/span&gt;&lt;/p&gt;

March 2020, the FAS issued ASU No. 2020-04 &#x201c;&lt;i&gt;Reference Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform
on Financial Reporting&#x201d; (&#x201c;ASU 2020-04&#x201d;).&lt;/i&gt; ASU 2020-04 provides optional guidance for a limited period of time to
ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments
are effective for the Company as of March 12, 2020 through December 31, 2022. The Company does not expect this ASU to have a material
impact on its consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

January 2020, the FASB issued ASU No. 2020-01, &lt;i&gt;Investments&#x2014;Equity Securities (Topic 321), Investments&#x2014;Equity Method and
Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)&#x2014;Clarifying the Interactions between Topic 321, Topic 323, and
Topic 815&lt;/i&gt; (a consensus of the Emerging Issues Task Force). This update clarifies whether an entity should consider observable transactions
that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative
and how to account for certain forward contracts and purchased options to purchase securities. For public entities, this guidance is
effective for fiscal years beginning after December 15, 2020. The Company does not expect this ASU to have a material impact on its consolidated
results of operations, cash flows and financial position. The adoption of this ASU has not had a material impact on the Company&#x2019;s
consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

December 2019, the FASB issued ASU 2019-12, &lt;i&gt;Income Taxes (Topic 740) &#x2013; Simplifying the Accounting for Income Taxes, &lt;/i&gt;which
simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also
improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12
is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted. The adoption of this ASU has not had a
material impact on the Company&#x2019;s consolidated results of operations, cash flows and financial position.&lt;/span&gt;&lt;/p&gt;

accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have
a material impact on the financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated
to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.&lt;/span&gt;&lt;/p&gt;

February 2016 the FASB issued ASU 2016-02, &lt;i&gt;Leases (Topic 842) &lt;/i&gt;(&#x201c;ASC 842&#x201d; or the &#x201c;new lease
standard&#x201d;). The Company adopted ASC 842 as of January 1, 2019, using the effective date method.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

new standard provides a number of optional practical expedients in transition. The Company has elected to apply the &#x201c;package of
practical expedients&#x201d; which allow the Company to not reassess: (i) whether existing or expired arrangements contain a lease, (ii)
the lease classification of existing or expired leases, or (iii) whether previous initial direct costs would qualify for capitalization
under the new lease standard. The Company has also elected to apply the short-term lease exemption for all leases with an original term
of less than 12 months, for purposes of applying the recognition and measurements requirements in the new lease standard.&lt;/span&gt;&lt;/p&gt;

adoption, the Company recognized its lease for manufacturing and office space (the &#x201c;Facility Lease&#x201d;) on the balance sheet
as an operating lease right-of-use asset in the amount of $&lt;span id="xdx_90E_eus-gaap--OperatingLeaseRightOfUseAsset_iI_pp0p0_c20190102__us-gaap--AdjustmentsForNewAccountingPronouncementsAxis__us-gaap--AccountingStandardsUpdate201602Member_z3QIEFnCJWn8" title="Operating lease right-of-use asset"&gt;714,416&lt;/span&gt; and as a lease liability of $&lt;span id="xdx_904_eus-gaap--OperatingLeaseLiability_iI_pp0p0_c20190102__us-gaap--AdjustmentsForNewAccountingPronouncementsAxis__us-gaap--AccountingStandardsUpdate201602Member_zHmT8Ig7tRDe" title="Lease liability"&gt;822,374&lt;/span&gt;. &lt;span id="xdx_906_eus-gaap--LesseeOperatingLeaseDescription_c20210101__20210930_zltbRLvpqQs2" title="Operating lease term description"&gt;The Facility Lease commenced

years&lt;/span&gt;. However, the renewal option to extend the Facility Lease is not included in the right-of-use asset or lease liability as the option
is not reasonably certain of exercise. The Company regularly evaluates the renewal option and when it is reasonably certain of exercise,
the Company will include the renewal period in its lease term.&lt;/span&gt;&lt;/p&gt;

September 1, 2018, and each subsequent September 1 during the term, the monthly rent under the Facility Lease will increase by 3%&lt;/span&gt;. Total
rent under the current building lease is charged to expense over the term of the lease on a straight-line basis, resulting in the same
monthly rent expense throughout the lease. The difference between the rent expense amount and the actual rent paid is recorded to operating
lease liability on the Company&#x2019;s condensed consolidated balance sheets.&lt;/span&gt;&lt;/p&gt;

the Facility Lease, the landlord agreed to pay the Company or the Company&#x2019;s contractors for tenant improvements made by the Company

The Company determined that these improvements were not specialized
and could be utilized by a subsequent tenant and, as such, the improvements were considered assets of the lessor. As of January 1, 2019,
the unamortized amount of tenant improvement allowance of $&lt;span id="xdx_903_ecustom--UnamortizedAmountOfTenantImprovementAllowance_iI_pp0p0_c20190102__us-gaap--AdjustmentsForNewAccountingPronouncementsAxis__us-gaap--AccountingStandardsUpdate201602Member_zrgjzx7tGFi2" title="Unamortized amount of tenant improvement allowance"&gt;81,481&lt;/span&gt; was treated as a reduction in measuring the right-of-use asset.&lt;/span&gt;&lt;/p&gt;

the Facility Lease, the Company pays the actual amounts for property taxes and insurance, excludes such payments from lease contract
consideration, and records such payments as incurred. The Company also pays the landlord for common area maintenance, which is considered
a nonlease component. For the Facility Lease, the Company has not elected the accounting policy to include both the lease and nonlease
components as a single component and account for it as the lease.&lt;/span&gt;&lt;/p&gt;

determining the right-of-use asset and lease liability, the Company applied a discount rate to the minimum lease payments under the Facility
Lease. ASC 842 requires the Company to use the rate of interest that the Company would have to pay to borrow on a collateralized basis
over a similar term an amount equal to the lease payments in a similar economic environment. Since the discount rate is not implicit
in the lease agreement, we utilized an estimated incremental borrowing rate provided by the Company&#x2019;s depository bank.&lt;/span&gt;&lt;/p&gt;

April 30, 2021, the Company entered into an agreement to sublease approximately &lt;span id="xdx_909_eus-gaap--AreaOfLand_iI_uSquareFoot_c20210430_zcofWncYfqej" title="Area of land"&gt;6,900&lt;/span&gt; square feet of its office and manufacturing space.
The sublease commenced on April 30, 2021 and will continue on a month-to-month basis until either party gives 30-days&#x2019; notice.
Unless 30-days&#x2019; notice is provided sooner, this sublease will end upon termination of the Company&#x2019;s Lease Agreement with
its current landlord. Rent was initially charged at $&lt;span id="xdx_90F_ecustom--RentalExpense_pp0p0_c20210429__20210430_zAyLzFhFPLma" title="Rent expense"&gt;5,989&lt;/span&gt; per month and increased to $&lt;span id="xdx_90D_ecustom--RentalExpense_pp0p0_c20210629__20210702_ze4MeKsl7vQe" title="Rent expense"&gt;11,978&lt;/span&gt; per month effective July 1, 2021. The Sublessor
is also responsible for its prorated share of utilities and other related costs. This new sublease does not change the Company&#x2019;s
legal relationship or financial obligations with its landlord. The Company continues to be responsible for all the remaining financial
obligations under its existing lease with the landlord. Accordingly, entering into the new sublease did not impact the carrying value
of the Company&#x2019;s operating lease right of use asset or operating lease liability. Moreover, after an initial two-month transitional
period, the rental rate per square foot under the new sublease is identical to the rental rate per square foot for the Company&#x2019;s
existing lease with its landlord which indicates that there is no impairment to the carrying value of the Company&#x2019;s operating lease
right of use asset.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

July 27, 2021, the Company entered into a Lease Termination Agreement with its current landlord for the &lt;span id="xdx_907_eus-gaap--AreaOfLand_iI_uSquareFoot_c20210727_z6rtBS8nNaud" title="Area of land"&gt;18,952&lt;/span&gt; square foot office and
manufacturing facility in Boulder, CO, which was previously scheduled to expire on &lt;span id="xdx_902_eus-gaap--LeaseExpirationDate1_dd_c20210725__20210727__us-gaap--TypeOfArrangementAxis__custom--LeaseTerminationAgreementMember_zXeSy0kHheTf" title="Lease expire date"&gt;August 31, 2022&lt;/span&gt;. The termination provides for the
Company to vacate the facility no later than November 15, 2021. In exchange for early termination from its lease obligation, the Company
paid a nominal lease termination fee on July 28, 2021. The termination was also contingent upon a successor tenant executing a new lease
with the landlord and the Company paying the remaining deferred rent and security deposit amounts (&lt;i&gt;See Contractual Payment Obligations
&lt;/i&gt;section). The landlord and successor tenant entered into a lease agreement on July 27, 2021. The remaining deferred rent and security
deposit will be paid in conjunction with the final rent payment.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

July 28, 2021, the Company entered into an agreement to lease &lt;span id="xdx_901_eus-gaap--AreaOfLand_iI_uSquareFoot_c20210728_zN3mw5fhoOsi" title="Area of land"&gt;11,491&lt;/span&gt; square feet of office and manufacturing space in Louisville, CO.
The lease commences on November 1, 2021 and continues through &lt;span id="xdx_904_eus-gaap--LeaseExpirationDate1_dd_c20210724__20210728__us-gaap--TypeOfArrangementAxis__custom--LeaseTerminationAgreementMember_zJDQ4X7f1m1i" title="Lease expire date"&gt;January 31, 2027&lt;/span&gt;. The Company has the option to renew the lease for an
additional 60-month period.&lt;/span&gt;&lt;/p&gt;

of December 31, 2019, there were &lt;span id="xdx_90E_ecustom--NumberOfUnitsVestedButNotSettled_c20190101__20191231__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockUnitsRSUMember_zr0v6SJAu0x6" title="Number of units, vested but not settled"&gt;6,750,000&lt;/span&gt; restricted stock units that had not been settled due to a dispute with a former employee over
the required withholding taxes to be paid to the Company for remittance to the appropriate tax authorities. The Company commenced an
arbitration action against the former employee regarding the dispute. The former employee also made claims in the arbitration action
against the Company for unpaid wages. As stated in a pleading in the arbitration, on March 9, 2020, the Company issued the former employee
&lt;span id="xdx_902_ecustom--NumberOfUnitsVestedAndSettled_c20200308__20200309__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockUnitsRSUMember_z17WdGRouHq7" title="Number of units, vested and settled"&gt;6,750,000&lt;/span&gt; shares of the Company&#x2019;s common stock in settlement of these restricted stock units after taking measures to mitigate
the Company&#x2019;s exposure to penalties and liability for the failure to properly withhold income taxes. The Arbitrator issued an interim
award of approximately $&lt;span id="xdx_90A_eus-gaap--LossContingencyDamagesAwardedValue_pp0p0_c20200308__20200309__us-gaap--AwardTypeAxis__us-gaap--RestrictedStockUnitsRSUMember_z83IRlsnuDBc" title="Interim awarded value"&gt;10,000&lt;/span&gt; in the Company&#x2019;s favor and a finding against the former employee. Effective June 9, 2020, the Arbitrator
issued his final award in the Company&#x2019;s favor in the Colorado arbitration. The Arbitrator found against the former employee and
awarded the Company costs of $&lt;span id="xdx_904_eus-gaap--LossContingencyDamagesAwardedValue_pp0p0_c20200607__20200609__srt--TitleOfIndividualAxis__custom--FormerEmployeeMember_zJwNGM5Ovb86" title="Interim awarded value"&gt;33,985&lt;/span&gt;, with interest at &lt;span id="xdx_902_ecustom--RestrictedStockUnitsSharesIssuedInterestPercentage_dp_uPure_c20200607__20200609__srt--TitleOfIndividualAxis__custom--FormerEmployeeMember_zKbPCGWx94Wh" title="Restricted stock units shares issued interest percentage"&gt;8&lt;/span&gt;% per year. Effective July 22, 2020, the Colorado Court confirmed the Arbitration
award and entered a final judgement in favor of the Company and against the former employee. The Company pursued collection of this debt
and has now collected the debt owed. This former employee continued to pursue separate litigation against the Company for recovery of
alleged consulting fees owed to him for the 2015 calendar year prior to his appointment as an executive officer of the Company. Effective
March 30, 2021, this separate litigation has now been settled. While the Company disputed the merits of the claims, the Company has agreed
and will be obliged to pay $&lt;span id="xdx_906_eus-gaap--LossContingencyDamagesPaidValue_pp0p0_c20210329__20210330_zg8GiAEbIbOk" title="Obligate to pay for dispute"&gt;40,000&lt;/span&gt; over eight months and to issue upon execution of the settlement agreement an aggregate of &lt;span id="xdx_904_eus-gaap--ProceedsFromIssuanceOfPrivatePlacement_c20210406__20210408_zBnLJLpv26P1" title="Issuance of private placement"&gt;1,000,000&lt;/span&gt;

lock-up agreement of six months, without registration rights, and pursuant to a private placement exemption and were valued at $&lt;span id="xdx_903_ecustom--AggregateSharesIssuedUponExecutionOfSettlement_c20210329__20210330_zl4c8v5acVtf"&gt;67,000&lt;/span&gt;.
The settlement agreement also included mutual releases and no admission of liability. The cost to the Company of this settlement, $&lt;span id="xdx_901_eus-gaap--OtherNonoperatingExpense_c20210101__20210930_pp0p0" title="Other expenses"&gt;107,000&lt;/span&gt;,

time to time, in the normal course of its operations, the Company is subject to litigation matters and claims. Litigation can be expensive
and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict, and the Company&#x2019;s
view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as
incurred. The Company records a liability for contingent losses when it is both probable that a liability has been incurred and the amount
of the loss is known. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company&#x2019;s operations
or its financial position, liquidity or results of operations.&lt;/span&gt;&lt;/p&gt;

of Redemption: As it was considered probable the Series B Preferred stock will become redeemable outside of the Company&#x2019;s control,
the Series B Preferred stock needs to be disclosed as temporary equity and restated at the balance sheet date at its redemption value
of &lt;span id="xdx_906_eus-gaap--DebtInstrumentRedemptionPricePercentage_dp_uPure_c20210101__20210930__us-gaap--StatementClassOfStockAxis__us-gaap--SeriesBPreferredStockMember_zua3LY9d3Dfe"&gt;120&lt;/span&gt;&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;%
the stated value of $&lt;span id="xdx_900_eus-gaap--DebtInstrumentConvertibleLiquidationPreferencePerShare_iI_uUSDPShares_c20210930__us-gaap--StatementClassOfStockAxis__us-gaap--SeriesBPreferredStockMember_zr7TYjVvCTj9"&gt;1,000

&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;As a result, on September 30, 2021, the Company adjusted the carrying
value of the Series B Preferred Stock to its redemption value of $&lt;span id="xdx_906_eus-gaap--TemporaryEquityAccretionToRedemptionValue_pp0p0_c20210101__20210930__us-gaap--StatementClassOfStockAxis__us-gaap--SeriesBPreferredStockMember_zNOlS2Egi2zg"&gt;&lt;span&gt;3,960,000&lt;/span&gt;

&lt;/span&gt;&lt;/span&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;non-cash redemption value adjustment. This redemption
value adjustment is treated as similar to a dividend on the preferred stock for GAAP purposes; accordingly, the redemption value adjustment
is therefore added to the &#x201c;Net Loss&#x201d; to arrive at &#x201c;Net Loss Attributable to Common Shareholders&#x2019;&#x201d; on the
Company&#x2019;s Consolidated Statements of Operations. In addition, since the Company does not have a balance of retained earnings, the
redemption value adjustment was recorded against additional paid-in capital.&lt;/span&gt;&lt;/p&gt;

Company must assess the likelihood that its net deferred tax assets will be recovered from future taxable income, and to the extent the
Company believes that recovery is not likely, the Company establishes a valuation allowance. Management&#x2019;s judgment is required
in determining the Company&#x2019;s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded
against the net deferred tax assets. The Company recorded a full valuation allowance as of September 30, 2021 and December 31, 2020.
Based on the available evidence, the Company believes it is more likely than not that it will not be able to utilize its net deferred
tax assets in the foreseeable future. The Company intends to maintain valuation allowances until sufficient evidence exists to support
the reversal of such valuation allowances. The Company makes estimates and judgments about its future taxable income that are based on
assumptions that are consistent with the Company&#x2019;s plans. Should the actual amounts differ from the Company&#x2019;s estimates,
the carrying value of the Company&#x2019;s deferred tax assets could be materially impacted.&lt;/span&gt;&lt;/p&gt;

that help improve their overall crop quality and yield, optimize energy and water efficiency, and satisfy evolving state and local construction
codes, permitting and regulatory requirements. In service of the CEA industry, our principal service and product offerings include:
(i) architectural design and licensed engineering of commercial scale thermodynamic systems specific to cultivation facilities, (ii)
liquid-based process cooling systems and other climate control systems, (iii) air handling equipment and systems, (iv) LED lighting,
benching and racking solutions for indoor cultivation, (v) automation and control devices, systems and technologies used for environmental,
lighting and climate control, and (vi) preventive maintenance services for CEA facilities. Our customers include commercial, state- and
provincial-regulated CEA growers in the U.S. and Canada and other international locations. Customers are those growers building new facilities
and those expanding or retrofitting existing facilities. Currently, our revenue stream is derived primarily from supplying our products,
services and technologies to commercial indoor facilities operating in the cannabis industry, ranging from several thousand to more than

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust
its operations as necessary. In early 2020 the Company took measures to reduce expenses in light of reduced orders and to preserve cash,
many of which were reversed by the end of the year when orders picked up and the overall business climate improved. Because the pandemic
continues in different parts of the world and in different ways in the United States, the Company continues to actively monitor its operations
and sales efforts and will make adjustments to its operations as necessary.</span></p>

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant
increase in shipments to U.S. ports, less cargo being shipped by air, a general shortage of containers, and domestic truck driver availability.
While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic have led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.</span></p>

the Company is continuing to navigate the financial, operational, and personnel challenges presented by the COVID-19 pandemic, the full
extent of the impact on our operational and financial performance will depend on future developments, including the duration and spread
of the pandemic, the potential uncertainty related to and proliferation of new strains, and related actions taken by the U.S. government,
state and local government officials, and international governments to prevent disease spread, all of which are uncertain, out of our
control and cannot be predicted at this time.</span></p>

accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced
recurring losses since its inception. Since inception, the Company has financed its activities principally through debt and equity financing,
customer deposits and revenues from completed contracts. Management expects to incur additional losses and cash outflows in the foreseeable
future in connection with its operating activities. Management believes that the economic dislocations in the overall economy, in the
near term, will impact our revenues, losses and cash flows. There can be no assurance that the Company will be able to raise debt or
equity financing in sufficient amounts, when and if needed, on acceptable terms or at all. If results of operations for 2021 do not meet
management&#8217;s expectations, or additional capital is not available, management believes it has the ability to reduce certain expenditures.
The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors,
including the overall economy, market demand for the Company&#8217;s products and services, the quality of product development efforts,
management of working capital, and continuation of normal payment terms and conditions for purchase of the Company&#8217;s products.
The Company believes its cash balances and cash flow from operations will be insufficient to fund its operations for the next 12 months.
If the Company is unable to substantially increase revenues, reduce expenditures, or otherwise generate cash flows from operations, then
the Company will need to raise additional funding to continue as a going concern. The foregoing factors raise substantial doubt about
the Company&#8217;s ability to continue as a going concern for a period of one year from the date the financial statements are issued.
These condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.</span></p>

the revenue standard, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the
customer. Most of the Company&#8217;s contracts contain multiple performance obligations that include engineering and technical services
as well as the delivery of a diverse range of climate control system equipment and components, which can span multiple phases of a customer&#8217;s
project life cycle from facility design and construction to equipment delivery and system installation and start-up.</span></p>

contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance
obligation is satisfied. When there are multiple performance obligations within a contract, the Company allocates the transaction price
to each performance obligation based on standalone selling price. When estimating the selling price, the Company uses various observable
inputs. The best observable input is the Company&#8217;s actual selling price for the same good or service, however, this input is generally
not available for the Company&#8217;s contracts containing multiple performance obligations. For engineering services, the Company estimates
the standalone selling price by reference to certain physical characteristics of the project, such as facility size and mechanical systems
involved, which are indicative of the scope and complexity of the mechanical engineering services to be provided. For equipment sales,
the standalone selling price is determined by forecasting the expected costs of the equipment and then adding an appropriate margin,
based on a range of acceptable margins established by management. Depending on the nature of the performance obligations, the Company
may use a combination of different methods and observable inputs if certain performance obligations have highly variable or uncertain
standalone selling prices. Once the selling prices are determined, the Company applies the relative values to the total contract consideration
and estimates the amount of the transaction price to be recognized as each performance obligation is fulfilled.</span></p>

Company recognizes revenue for the sale of goods when control transfers to the customer, which primarily occurs at the time of shipment.
The Company&#8217;s historical rates of return are insignificant as a percentage of sales and, as a result, the Company does not record
a reserve for returns at the time the Company recognizes revenue. The Company has elected to exclude from the measurement of the transaction
price all taxes (e.g., sales, use, value added, and certain excise taxes) that are assessed by a governmental authority in connection
with a specific revenue-producing transaction and collected by the Company from the customer. Accordingly, the Company recognizes revenue
net of sales taxes. The revenue and cost for freight and shipping is recorded when control over the sale of goods passes to the Company&#8217;s
customers.</span></p>

certain sales commissions and incentives, which are included in selling, general and administrative expenses, and are payable only when
associated revenue has been collected and earned by the Company.</span></p>

uncertainty, project financing concerns, and the licensing and qualification of our prospective customers, which are out of the Company&#8217;s
control, make it difficult for the Company to predict when it will recognize revenue on its remaining performance obligations. There
are risks that the Company may not realize the full contract value on customer projects in a timely manner or at all, and completion
of a customer&#8217;s cultivation facility project is dependent upon the customer&#8217;s ability to secure funding and real estate,
obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the time it takes
for customers to complete a project, which corresponds to when the Company is able to recognize revenue, is driven by numerous factors
including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business; (ii) the complexities
and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government delays in approving
licenses and permits due to lack of staff or the large number of pending applications, especially in states where there is no cap on
the number of cultivators; (iv) the customer&#8217;s need to obtain cultivation facility financing; (v) the time needed, and coordination
required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate control systems
can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system; (vii) the availability
of power; and (viii) delays that are typical in completing any construction project.</span></p>

was attributable to customer contracts for which the Company has only received an initial advance payment to cover the allocated value
of the Company&#8217;s engineering services (&#8220;engineering only paid contracts&#8221;). There is the risk that the equipment portion
of these engineering only paid contracts will not be completed or will be delayed. These reasons include the customer being dissatisfied
with the quality or timeliness of the Company&#8217;s engineering services, delay or abandonment of the project because of the customer&#8217;s
inability to obtain project financing or licensing, or other reasons such as a challenging business climate including an overall post-Covid-19
economic disruption or change in business direction. After the customer has made an advance payment for a portion of the equipment to
be delivered under the contract (&#8220;partial equipment paid contracts&#8221;), the Company is typically better able to estimate the
timing of revenue recognition since the risks and delays associated with licensing, permitting and project funding are typically mitigated
once the initial equipment payment is received. There is significant uncertainty regarding the timing of the Company&#8217;s recognition
of revenue on its remaining performance obligations, and there is no certainty that these will result in actual revenues. The backlog
at September 30, 2021, includes booked sales orders of $<span id="xdx_906_eus-gaap--RevenueRemainingPerformanceObligation_iI_pp0p0_uUSD_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--OrderOrProductionBacklogMember_zQiH5yXcW5Ol" title="Remaining performance obligations">1,250,000</span> from several customers that the Company does not expect to be realized

Company recognizes the cost resulting from all share-based compensation arrangements, including stock options, restricted stock awards
and restricted stock units that the Company grants under its equity incentive plan in its condensed consolidated financial statements
based on their grant date fair value. The expense is recognized over the requisite service period or performance period of the award.
Awards with a graded vesting period based on service are expensed on a straight-line basis for the entire award. Awards with performance-based
vesting conditions, which require the achievement of a specific company financial performance goal at the end of the performance period
and required service period, are recognized over the performance period. Each reporting period, the Company reassesses the probability
of achieving the respective performance goal. If the goals are not expected to be met, no compensation cost is recognized and any previously
recognized amount recorded is reversed. If the award contains market-based vesting conditions, the compensation cost is based on the
grant date fair value and expected achievement of market condition and is not subsequently reversed if it is later determined that the
condition is not likely to be met or is expected to be lower than initially expected.</span></p>

risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected term of the option. The Company
determines the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility,
expected term or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, the Company may
use different assumptions for options granted throughout the year. During the nine months ended September 30, 2021, the valuation assumptions

August 2020, the Financial Accounting Standards Board (&#8220;FASB&#8221;) issued Accounting Standards Update (&#8220;ASU&#8221;) 2020-06,
Debt &#8212; Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging &#8212; Contracts in Entity&#8217;s
Own Equity (Subtopic 815-40) (&#8220;ASU 2020-06&#8221;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates
the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies
the derivative scope exception guidance pertaining to equity classification of contracts in an entity&#8217;s own equity. The new standard
also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#8217;s
own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis,
with early adoption permitted beginning on January 1, 2021. The Company early adopted ASU 2020-06 effective January 1, 2021. The early
adoption of ASU 2020-06 impacted the Company&#8217;s accounting for the issuance of its Series B Redeemable Convertible Preferred Stock

the lease classification of existing or expired leases, or (iii) whether previous initial direct costs would qualify for capitalization
under the new lease standard. The Company has also elected to apply the short-term lease exemption for all leases with an original term
of less than 12 months, for purposes of applying the recognition and measurements requirements in the new lease standard.</span></p>

April 30, 2021, the Company entered into an agreement to sublease approximately <span id="xdx_909_eus-gaap--AreaOfLand_iI_uSquareFoot_c20210430_zcofWncYfqej" title="Area of land">6,900</span> square feet of its office and manufacturing space.
The sublease commenced on April 30, 2021 and will continue on a month-to-month basis until either party gives 30-days&#8217; notice.
Unless 30-days&#8217; notice is provided sooner, this sublease will end upon termination of the Company&#8217;s Lease Agreement with
its current landlord. Rent was initially charged at $<span id="xdx_90F_ecustom--RentalExpense_pp0p0_c20210429__20210430_zAyLzFhFPLma" title="Rent expense">5,989</span> per month and increased to $<span id="xdx_90D_ecustom--RentalExpense_pp0p0_c20210629__20210702_ze4MeKsl7vQe" title="Rent expense">11,978</span> per month effective July 1, 2021. The Sublessor
is also responsible for its prorated share of utilities and other related costs. This new sublease does not change the Company&#8217;s
legal relationship or financial obligations with its landlord. The Company continues to be responsible for all the remaining financial
obligations under its existing lease with the landlord. Accordingly, entering into the new sublease did not impact the carrying value
of the Company&#8217;s operating lease right of use asset or operating lease liability. Moreover, after an initial two-month transitional
period, the rental rate per square foot under the new sublease is identical to the rental rate per square foot for the Company&#8217;s
existing lease with its landlord which indicates that there is no impairment to the carrying value of the Company&#8217;s operating lease
right of use asset.</span></p>

The termination provides for the
Company to vacate the facility no later than November 15, 2021. In exchange for early termination from its lease obligation, the Company
paid a nominal lease termination fee on July 28, 2021. The termination was also contingent upon a successor tenant executing a new lease
with the landlord and the Company paying the remaining deferred rent and security deposit amounts (<i>See Contractual Payment Obligations
</i>section). The landlord and successor tenant entered into a lease agreement on July 27, 2021. The remaining deferred rent and security
deposit will be paid in conjunction with the final rent payment.</span></p>

incurred. The Company records a liability for contingent losses when it is both probable that a liability has been incurred and the amount

Company must assess the likelihood that its net deferred tax assets will be recovered from future taxable income, and to the extent the
Company believes that recovery is not likely, the Company establishes a valuation allowance. Management&#8217;s judgment is required
in determining the Company&#8217;s provision for income taxes, deferred tax assets and liabilities, and any valuation allowance recorded
against the net deferred tax assets. The Company recorded a full valuation allowance as of September 30, 2021 and December 31, 2020.
Based on the available evidence, the Company believes it is more likely than not that it will not be able to utilize its net deferred
tax assets in the foreseeable future. The Company intends to maintain valuation allowances until sufficient evidence exists to support
the reversal of such valuation allowances. The Company makes estimates and judgments about its future taxable income that are based on
assumptions that are consistent with the Company&#8217;s plans. Should the actual amounts differ from the Company&#8217;s estimates,
the carrying value of the Company&#8217;s deferred tax assets could be materially impacted.</span></p>

our response to the COVID-19 pandemic and the government and business response, the Company took and continues to take measures to adjust

are experiencing unexpected and uncontrollable delays with our international supply of products and shipments from vendors due to a significant

While these delays have moderately improved in recent months, we, along with many other importers of goods across all industries, continue
to experience severe congestion and extensive wait times for carriers at ports across the United States. In addition, restrictions imposed
by local, state and federal agencies due to the COVID-19 pandemic have led to reduced personnel of importers, government staff and others
in our supply chain. We have been working diligently with our network of freight partners and suppliers to expedite delivery dates and
provide solutions to reduce further impact and delays. However, we are unable to determine the full impact of these delays and how long
they will continue as they are out of our control.</span></p>

accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern,
which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has experienced
recurring losses since its inception. Since inception, the Company has financed its activities principally through debt and equity financing,
customer deposits and revenues from completed contracts. Management expects to incur additional losses and cash outflows in the foreseeable
future in connection with its operating activities. Management believes that the economic dislocations in the overall economy, in the
near term, will impact our revenues, losses and cash flows. There can be no assurance that the Company will be able to raise debt or
equity financing in sufficient amounts, when and if needed, on acceptable terms or at all. If results of operations for 2021 do not meet
management&#8217;s expectations, or additional capital is not available, management believes it has the ability to reduce certain expenditures.
The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors,
including the overall economy, market demand for the Company&#8217;s products and services, the quality of product development efforts,
management of working capital, and continuation of normal payment terms and conditions for purchase of the Company&#8217;s products.
The Company believes its cash balances and cash flow from operations will be insufficient to fund its operations for the next 12 months.
If the Company is unable to substantially increase revenues, reduce expenditures, or otherwise generate cash flows from operations, then
the Company will need to raise additional funding to continue as a going concern. The foregoing factors raise substantial doubt about
the Company&#8217;s ability to continue as a going concern for a period of one year from the date the financial statements are issued.
These condensed consolidated financial statements do not include any adjustment that might result from the outcome of this uncertainty.</span></p>

the revenue standard, a performance obligation is a promise in a contract with a customer to transfer a distinct good or service to the
customer. Most of the Company&#8217;s contracts contain multiple performance obligations that include engineering and technical services
as well as the delivery of a diverse range of climate control system equipment and components, which can span multiple phases of a customer&#8217;s
project life cycle from facility design and construction to equipment delivery and system installation and start-up.</span></p>

contract&#8217;s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance
obligation is satisfied. When there are multiple performance obligations within a contract, the Company allocates the transaction price
to each performance obligation based on standalone selling price. When estimating the selling price, the Company uses various observable
inputs. The best observable input is the Company&#8217;s actual selling price for the same good or service, however, this input is generally
not available for the Company&#8217;s contracts containing multiple performance obligations. For engineering services, the Company estimates
the standalone selling price by reference to certain physical characteristics of the project, such as facility size and mechanical systems
involved, which are indicative of the scope and complexity of the mechanical engineering services to be provided. For equipment sales,
the standalone selling price is determined by forecasting the expected costs of the equipment and then adding an appropriate margin,
based on a range of acceptable margins established by management. Depending on the nature of the performance obligations, the Company
may use a combination of different methods and observable inputs if certain performance obligations have highly variable or uncertain
standalone selling prices. Once the selling prices are determined, the Company applies the relative values to the total contract consideration
and estimates the amount of the transaction price to be recognized as each performance obligation is fulfilled.</span></p>

Company recognizes revenue for the sale of goods when control transfers to the customer, which primarily occurs at the time of shipment.
The Company&#8217;s historical rates of return are insignificant as a percentage of sales and, as a result, the Company does not record
a reserve for returns at the time the Company recognizes revenue. The Company has elected to exclude from the measurement of the transaction
price all taxes (e.g., sales, use, value added, and certain excise taxes) that are assessed by a governmental authority in connection
with a specific revenue-producing transaction and collected by the Company from the customer. Accordingly, the Company recognizes revenue
net of sales taxes. The revenue and cost for freight and shipping is recorded when control over the sale of goods passes to the Company&#8217;s
customers.</span></p>

uncertainty, project financing concerns, and the licensing and qualification of our prospective customers, which are out of the Company&#8217;s
control, make it difficult for the Company to predict when it will recognize revenue on its remaining performance obligations. There
are risks that the Company may not realize the full contract value on customer projects in a timely manner or at all, and completion
of a customer&#8217;s cultivation facility project is dependent upon the customer&#8217;s ability to secure funding and real estate,
obtain a license and then build their cultivation facility so they can take possession of the equipment. Accordingly, the time it takes
for customers to complete a project, which corresponds to when the Company is able to recognize revenue, is driven by numerous factors
including: (i) the large number of first-time participants interested in the indoor cannabis cultivation business; (ii) the complexities
and uncertainties involved in obtaining state and local licensure and permitting; (iii) local and state government delays in approving
licenses and permits due to lack of staff or the large number of pending applications, especially in states where there is no cap on
the number of cultivators; (iv) the customer&#8217;s need to obtain cultivation facility financing; (v) the time needed, and coordination
required, for our customers to acquire real estate and properly design and build the facility (to the stage when climate control systems
can be installed); (vi) the large price tag and technical complexities of the climate control and air sanitation system; (vii) the availability

was attributable to customer contracts for which the Company has only received an initial advance payment to cover the allocated value
of the Company&#8217;s engineering services (&#8220;engineering only paid contracts&#8221;). There is the risk that the equipment portion
of these engineering only paid contracts will not be completed or will be delayed. These reasons include the customer being dissatisfied
with the quality or timeliness of the Company&#8217;s engineering services, delay or abandonment of the project because of the customer&#8217;s
inability to obtain project financing or licensing, or other reasons such as a challenging business climate including an overall post-Covid-19
economic disruption or change in business direction. After the customer has made an advance payment for a portion of the equipment to
be delivered under the contract (&#8220;partial equipment paid contracts&#8221;), the Company is typically better able to estimate the
timing of revenue recognition since the risks and delays associated with licensing, permitting and project funding are typically mitigated
once the initial equipment payment is received. There is significant uncertainty regarding the timing of the Company&#8217;s recognition
of revenue on its remaining performance obligations, and there is no certainty that these will result in actual revenues. The backlog
at September 30, 2021, includes booked sales orders of $<span id="xdx_906_eus-gaap--RevenueRemainingPerformanceObligation_iI_pp0p0_uUSD_c20210930__us-gaap--FiniteLivedIntangibleAssetsByMajorClassAxis__us-gaap--OrderOrProductionBacklogMember_zQiH5yXcW5Ol" title="Remaining performance obligations">1,250,000</span> from several customers that the Company does not expect to be realized

Company recognizes the cost resulting from all share-based compensation arrangements, including stock options, restricted stock awards
and restricted stock units that the Company grants under its equity incentive plan in its condensed consolidated financial statements
based on their grant date fair value. The expense is recognized over the requisite service period or performance period of the award.
Awards with a graded vesting period based on service are expensed on a straight-line basis for the entire award. Awards with performance-based
vesting conditions, which require the achievement of a specific company financial performance goal at the end of the performance period
and required service period, are recognized over the performance period. Each reporting period, the Company reassesses the probability
of achieving the respective performance goal. If the goals are not expected to be met, no compensation cost is recognized and any previously
recognized amount recorded is reversed. If the award contains market-based vesting conditions, the compensation cost is based on the
grant date fair value and expected achievement of market condition and is not subsequently reversed if it is later determined that the
condition is not likely to be met or is expected to be lower than initially expected.</span></p>

grant date fair value of stock options is based on the Black-Scholes Option Pricing Model (the &#8220;Black-Scholes Model&#8221;). The
Black-Scholes Model requires judgmental assumptions including volatility and expected term, both based on historical experience. The
risk-free interest rate is based on U.S. Treasury interest rates whose term is consistent with the expected term of the option. The Company
determines the assumptions used in the valuation of option awards as of the date of grant. Differences in the expected stock price volatility,
expected term or risk-free interest rate may necessitate distinct valuation assumptions at those grant dates. As such, the Company may
use different assumptions for options granted throughout the year. During the nine months ended September 30, 2021, the valuation assumptions

Own Equity (Subtopic 815-40) (&#8220;ASU 2020-06&#8221;) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates
the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies
the derivative scope exception guidance pertaining to equity classification of contracts in an entity&#8217;s own equity. The new standard
also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity&#8217;s
own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for
all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis,
with early adoption permitted beginning on January 1, 2021. The Company early adopted ASU 2020-06 effective January 1, 2021. The early
adoption of ASU 2020-06 impacted the Company&#8217;s accounting for the issuance of its Series B Redeemable Convertible Preferred Stock

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

<a href="javascript:void(0);" onclick="top.Show.toggleNext( this );">- Definition</a><div><p>The maximum number of securities classified as temporary equity that are permitted to be issued by an entity's charter and bylaws. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.</p></div>
