I'm building a grow box out of an old big speaker box and need help figuring were to add the intake and exhaust, I have two12v pc fans where do I add the intake and exhaust?
I have 0 experience but from my research exhaust should always be at the highest possible point and intake at the lowest possible point. Because heat rises the coldest air is at the bottom and hottest air is at the top. So basically in take at the bottom for cool air and exhaust out all the hot air from the top. Hope that helps
Intake at the bottom and outtakeat the top. Are you using any kind of carbon filter or anything to eliminate smell?
thanks man this really helped, I'm thinking of putting one but I need to figure out how to make a carbon filter
