Looking for ideas to make a light and odor proof air intake. The room is 720 sq', or 8x10x9. I tried a 12x12" darkroom vent but too much resistance for my 8" can fan. Could add a 12x14 but is there anyway to calculate passive air flow through these things so its not just trial and error? I could just use ducting and bend it to prevent light from passing through I guess. Not very elegant.
Which brings me the the next problem, odor control. Is there a control that will keep the fan running for a little negative pressure then kick up the speed to vent when the temps get too high? Already got a scrubber.
