well my exhaust is 6 inches wide (round) so it's total circumference is 18.84
i bought a hole saw which made holes 2.125 inches wide = 6.6725
i made 9 holes in a 3x3 area in the side = 60~ which is 3.3x the size of the exhaust.
now i'm gonna make a light box trap thing
anyone know the rule of thumb to making a light box (like how big should the hole be in regard to my passive intakes?
if i made too many passive intakes i can just cover them up so i can still create negative pressure. i think i made too many holes for my intake though
