in the summer, my big cabinet stays around 90 degrees, 24/7, even with all the fans and ventilation running :wtf: ... so what ? the spoiled little bitches are pampered, if I stuck them outside, they'd be 105 degrees ... I can't afford to run my A/C for myself, let alone the plants ... seriously though, optimum growth is seen in the 70's, but it takes a LOT of abuse to kill a WEED ... try to keep your temps down, but don't make yourself sick, stressing over it ... :jointsmile:
