you should hook up the cool tube A.S.A.P. you need to check out Mellow Mans cool tube thread in the FAQs section and Turtle420 thread in the indoor closet growroom section I'm pretty sure the cool tube thing would help you out big time cause I'm have the same problem but all I need to do is make a few adjustments to my cool tube and I'll be fine I hope. I dont know if you also said that your exhaust fan was at the top of the room because heat does rise so a good place for the exhaust would be at the top and intake at the bottom like you have :thumbsup:
