i had serious problems when it came to cooling my room with the HID lights and t5's. The only effective solution that i found was buying a portable a/c and putting it in the room itself to cool it down. I tried probably 10 other ways to fix this problem before finally finding a cheap enough p A/C on craigs list to put that in there. Even after buying it , im still paying monthly for the electricity it takes to run. I run the portable a/c 24/7! I try to be optimistic about everything buy cool air in florida isnt easy. The attic idea isnt too bad either. Thats where i have my exhaust going. We dont want the flir to see our exhaust and then knock : D .

Good luck bud.
