GMSgrowsanswered grow question 4 years ago Resin production is 24/7, it is for protection of the plants from bugs first, birds, sun, rain, etc. There are ways to lightly stress your plants near the end to make them create even more resin. Light moved down for an hour or 2 here and there but not long enough to damage your tops, just long enough to trigger resin protection. This I do in the last week. Always with a fan blowing over them so the bud isnt heating, just getting to much light, like I said, not for too long. Cheers
