hi guy, i can see you have spent some time and cash trying to get
yourself set-up.

what you need to do is,either get a blower for exhaust or use the
fans you have to exhaust the hot air out.
while you definately need air circulation inside your grow room, that
won't help to regulate temps.

here are a few links that might help, a few for DIY and one for buying

justanotherbozo Reviewed by justanotherbozo on . My 1st Grow Room!! Too Hot!! 7x2x5 closet, 600w HPS light, I have 4 ventilation fans ($12 bathroom fans 50cfm) I have one large box fan that stays on high, and one of the bathroom fans is actually placed in an open window, with ducting tube blowing the cool air directly at the light, as well as one fan the ducting tube directing the air out into the bedroom. The temp is staying at around 91F. I cant afford much more but I can stop now I have done a lot of work and already spent a lot of money on this, but I want to do it Rating: 5
