Believe me, I've read threads on several forums and done much searching using google, but haven't been able to locate a definitive answer to this question. And here it is. I'll be starting with a 6" fan and two 6" passive intakes for ventilation. Where should the intake holes be placed? Directly across from the fan? Can the fan be hung near the top of the wall, near the ceiling with the intakes holes near the bottom of the opposite wall? Diagonally across? Thanks for your help.
I would suck air out the top of grow area in one corner and in the opposite corner near the floor place place my passive intake vent. Do your best to have at least remove air up high and intake down low.
