i read that the dark room louvers restrict a lot of air that comes in
im going to use a pc power supply fan as an exhaust and wire up 3 more fans to suck air out of the chamber through 3 home made filter. however, i have 3 questions
1) the rule of thumb is that the passive intake size should be the same size as your exhaust fan, if i use the dark room louvers do i need to compensate for this general rule by doubling it or will the exhaust just create a negative pressure which sucks air from outside? should i install intake fans on the louvers?
2) how does the fan on a power supply work, i understand it sucks in air, but where does it ventilate to? , the grow box tutorial i read used a power supply fan as an exhaust fan but also wired up the power supply to two exhaust tubes which acted as carbon filters (sucking from the chamber). Does a power supply fan simply draw the air up to cool the power supply and than just redirect the hot air back down?
3) what if my passive intake holes are bigger than my exhaust? what about vice versa?
