Odor control, will it be enough?

Ok guys i have an odor control related question. I've got a single plant growing under cfls in my closet, and Im intending to drape a heavy duty plastic sheet from the cieling to the floor, securing it around the edges with duct tape. I will leave the bottom part untaped in order to access my plants, and have a single exhaust tube running out from under this plastic sheet to a carbon filter that i've set up. My question is will a small carbon filter and a plastic sheet w/passive intake be enough to conceal the odor in my closet for one plant? or should i consider taking more steps to ensure i dont stink up my house? ps for those of you wondering i am not growing in my parents place, i simply dont want visitors noticing a smell coming from my room.
Thanks for any advice y'all can give me

as long as none of the air is pushed out other than through the carbon

ok, im thinking i should weight down the bottom of the plastic with either wood or stones, im assuming there will be some air passing through on the portion of the sides that i leave untaped for access, but as there is no real intake channel, im going to assume that air will be entering, not exiting, through these openings.
