hello so my rooms are going to be 5'x5'x6'. Running carbon filter through a 6" 400 cfm inline exhaust fan through a/c hood then out of the room.
I plan on having a passive air intake the question is what size does it need to be to still have negative pressure?
8"? 10"? Or 12"
Prefer it to be one of those sizes so I can attach a bug screen. ( fuck those plant eating bastards)
Don't know if this changes things but I will be running co2 in my flowering room.
Thank you for any advice or previous experiences you want to share.
Stay high happy and healthy.
