my temps r chillin at 82 F it doesnt really get higher then that now, since i cut the two holes in my door. one at the top and one at the bottom. i attached a fan to the door blowing in at the bottom to bring in fresh air. i also have a fan on the top shelf of the clooset blowing right out of the hole so it blows hot air out. i also have two Green Pad co2 generators hanging about 1 foot and a half above the canopy. i mist them everytime i water my plants.
