The Art of Finishing a Cannabis Plant — 42 Years of Grow Room Experience 🌱
Finishing a cannabis plant properly is a horticultural discipline most home growers skip. In this video I sit down in my 16-year grow room and walk through what four decades of experience has taught me about the final stage of the plant — the humidity control, the water activity, the vapor pressure deficit, and why hang-drying in a controlled environment outlasts every storage product I’ve tested.
Behind me is a crop I cut down on April 30, 2022 and have been hang-drying for 4.5 years in the same room. That cut happened the day after a motor-vehicle accident that pulled me out of growing for a stretch. The 2026 outdoor season was my first full return, and this video documents how I’m bringing it to the finish line.
I also talk about the MediChocolate Thai — a breeding project of mine, Chocolate Tie crossed with MediKush — and about the room itself, which I built in 2010 with my father and my late friend Jason Wilcox. Jason and I worked together on the Coalition Against Repeal, the Health Canada constitutional challenge that protected patient cultivation rights in Canada. That story deserves its own documentary and I plan to make one.
What You’ll Learn:
Why finishing a plant is a separate discipline from growing one
Water activity (aW), relative humidity, and vapor pressure deficit (VPD)
Why hang-drying in a controlled room outlasts storage packs
The horticultural history of long-form hang curing
The 1-option, 2-option, 3-option decision framework for growers
Why patient growers approach curing as an art, not a step
