hey guys thanks alot i really appreciate ur advice. i drilled a hole in the side of the cab today and put a 90 degree piece of pvs pipe in the hole and caulked around it. i got a fan inside right in front of the hole so it draws fresh air in. later this week im gonna go to the compuer store and get another computer fan for the inside. so ill have the exhaust fan,the fan inside, and another fan inside so the temps should drop to the high 70's even though now they are at 84 and staying there. i ran outof mylar after i did the whole insideof the cab so i spray painted the inside of the door white. will that reflect light good? the plants are growin kinda fast under this hps. i will post pics tomorrow morning when the lights come on.
