No that's right, you have the carbon filter inside, it has holes in it so the air goes in there, the filter should be at the top of your grow space, so yeah you suck air though the filter into ducting out of your closet.
MegaOctane12 Reviewed by MegaOctane12 on . carbon filter setup "PLEASE" Thanks for taking the time to look. This is my first time growing an im having trouble working out how my systemair fan connects to the carbon filter . And do i have the carbon filter inside or outside the tent ? at the moment i have it inside connected to the fan and blowing air out through the duckting outside the tent. So basicly i got my fan sucking the air in the tent through the filter and blowing outside the tent .But im sure im wrong "PLEASE HELP" Rating: 5
