Home cannabis growers experiment with different techniques to produce the best end product possible, know as “shocking plants”. These include stop watering (water deprivation), stressing, molasses, ice cubes, splitting stems and darkness to increase resin production before harvest. Some of these hacks can fatten up buds and boost THC levels.
Should You Leave Plants In Darkness Before Harvest?
Yes, a period of darkness and shocking plants before harvest can trick cannabis in to believing winter has arrived early and forces then to use remaining nutrient resources towards flower production. You should keep the plant in 48-72 hrs of darkness before harvest, and additionally stop watering for 24-48 hrs.
