Poncho 'Milla Reviewed by Poncho 'Milla on . Carbon filter efficiency Hi! Im starting a indoor closet grow, and im wondering: If i buy cheap carbon filters for intake + outtake, will they remove the weed smell from the closet ? If just a pair doesnt help, can i stack them for more efficiency ??? best regards Rating: 5
