cooling

Alright, just started my first grow, and I'm already in trouble. My current setup is a 3' x 3' x 6'11" tent. I have a 6 inch intake fan and a 6 inch exhaust fan. My light/reflector is the Phantom CMH 315W. The reflector is uncovered (no glass lid), so it is running a bare bulb. I've had the...
