Estimated Yield per Plant
Disclosure Of Significant Unobservable Inputs Used In Fair Value Measurement Of Assets [Line Items]
Unobservable Inputs	Estimated Yield per Plant – varies by strain and is obtained through historical growing results (trailing 6-months moving average) or grower estimate if historical results are not available.
Sensitivity	A slight increase in the estimated yield per plant would result in a significant increase in fair value, and vice versa.
