In weeks 6, 7 and 8 I may even drop em to like 55 or 60 a few random nights just to see if I can spur on some trich production...
I can attest to the 55f-60f nights putting on massive trich coverage. I don't think the room that produced these buds ever saw 80f with the lights on, 55f-60f was lights out temps for the entire grow.
