Well I decided to move my tent from underneath the stairs to a spare bedroom in my basement instead. Hoping heat will not be an issue anymore. I have the exhaust going straight into the room but its much larger and has AC. If I have to I can vent out a window but then ill have to build a stealth window box. So far the temps are right at 80 with the light at 600watts. Finally I'm able to run my light to the max and hopefully the best bang for my buck. Here's a few pics of the move...
