    a 5" extraction and a 4" outtake should be sufficient. what are the temps of the room that the tent is in? is there a window open in the same room? having a fan blowing just above the top of the plants will help too.

    ok so these two extraction fans are they both sucking air from the top of the tent and the intake blowing air into the tent from the bottom? or are you using an extraction fan at the top of the tent and an extraction at the bottom of the tent?

    passive intake sucks mate, you would be best off using an intake that blows air into the tent rather than trying to suck air in through the passive intake flaps
