My friends room is 65 to 70 deg. normaly, he hits the 1000 mh and its 105 deg. in 1 hour. window venting and fresh air are not possible, he says the person in the next apt. is a trooper....hhhmmm a trooper that delivers pizza and pays for food with foodstamps....I think hes a little to parinoid imo but hey, its his grow, anyway he uses a freon 10,000 btu air conditioner venting the hot air inside the same room but not in the grow chamber, it works great, his room is never over 72 deg. and the a/c unit helps w/ humidity...but he doesnt have much of a condinsation problem...that I dont understand, I had an a/c unit once with a tray on the bottom that constantly filled with water. Maybe not all a/c units work the same..??
