I'm not super enthusiastic about you hiding the smell from housemates...once you open the closet the smell will permeate the room even with filtering. the whole floor my tent is in gets really loud once I unzip it for a look or if I need to water plants and stays that way for a good while and it's been like that since the week before flower. Even if you're in a legal state (or country) if you're in on-campus housing of any kind I'd be pretty sure that's grounds for removal and possible dismissal from school, so be really really careful.
