thank you so much stink for taking the time to help me out. so i ahve vented the exhaust through the attick. the portable a/c really cant be vented anywhere else. i would rather not even use that thing if i didnt have to. i think im goin to duct the a/c vent which is right outside the room, and lead it into the grow room. if i can get my hands on a cheap 600w hps im gonna get one. i dont want high temps with my babies about to start sprouting. this is just s trial run. would love to keep the 1000w but its almost impossible to keep temps down inthe conditions i have. i have it stable at aabout 88F. 50 humid. we will see how the next week plays out. but i still have those damn yellow splotches on about 5 or 6 leaves. i dont like that. plants look healthy otherwise. and ideas? thanks so much everyone!!
