TL;DR whats a good intake exhaust vent for a 30x30x18 in box
First thing is first. with one exhaust fan and one intake fan, you aren't getting much exhaust. If you can, move the intake fan (assuming it's near the floor of the cab) towards the top for exhaust and use passive intake.I see a lot of people thinking 1 exhaust and 1 intake is going to cool down a room when it doesn't.Also, if you want some REAL exhaust with a carbon scrubber get something like this http://www.amazon.com/VenTech-IF4CF...ER5C/ref=pd_sim_sbs_lg_1/182-0508441-3968062A 4" in-line with a carbon scrubber combo. Probably cheaper to make your own scrubber VIA the link you posted. But a in line will help drop the temps dramatically
