My tent has 8 inches Holes in it for fans, I'm not going to use a filter for smell don't need it in my basement. Can't I just use two 8 inch duct fans one for drawing air in and one for exit air and use my regular oscillating fans in tent. Be using led so heat won't be a problem just need fresh air so humidity does get to high. I have seen them for about $30.00 a peace.
You could absolutely do that! Or, you could simply have oscillating fans and one exhaust fan! Keep those bottom flaps or vents somewhat open and exhaust thru the top
