I have a 250 hps in my closet along with a 9 bulb 23w cfl contraption. My closet is in a spare room, the room has a door but the closet does not. I decided to seal up the closet by putting a poly door with a zipper on it. I have a 6" 160 cfm duct fan exhausting air out the top right corner and I have a 4 inch flange poked through the bottom as an intake. In my area the outdoor temps are the highest I've ever seen them. Heat index of 115 today. I only have one air conditioner in the house and it doesn't have much of an affect on the spare room. Today the temps in the closet with it closed were 96-101, and with it open only dropped to 93. What can I do to counter the heat of the summer? My plants are already 7 weeks into flower and I don't want to loose this harvest because of this damn heatwave and drought.
