Hey Newb, I like to start veg from germ at a temp of 78-82 degrees with 60-70% humidity then early flower I’ll drop it to 73-77 once in flower I’ll wait till last 5-6 weeks and drop temps bout 5 degrees each 1-2 weeks I’m able to get temps to low 60’s light off to mid to low 70’s light on. I don’t believe it’s the temp range is as important as breaking the norm temp when flip to flower this helps let the plant know it’s go time.
