Now for a question of my own. I am having trouble getting my temps down. Light is a 600w MH/HPS cool tube, the 6" inline fan is a 160cfm, and the box is 2x3x5.5. With no other ventilation and using only the cool tube the temp is 100 degrees. Obviously way too high. I added a small vent at the bottom of the box and will add an exhaust fan attached to an odor filter at the top of the box. What size fan will I need to properly kill the smell and will it be enough to drop the temps?
