I have been using hlgs far red propagator led bulb in my flower tent at 10 minutes before and 10 minutes after lights out. I stopped using it at lights on… To ensure my buds got bigger… Otherwise shortening the cycle too short, I felt wouldn’t leave enough time. I want as large aaannnddd frosty harvest as possible.
Anyway great results… Check out the “grove bags” thread I have pics posted there of some frosty nugs.
