Need help quick before i head out to the store

well ATM im kind of limited but im thinkin about moving down to the crawl space and growing possibly 5-10 plants down there with a fan connected to the sewer like on that cannabis faq page, its either that or the closet, ill try to get a centralfugel fan hooked up to that and just blast it all out into the sewer, they cant trace it back haha hehe :o i should actually work on the crawl space, clean it up and put like 54934 mouse traps in there... and actually move in there that be pretty fun :P course it will be a project, right now im just lookin for a bit of bud, but once i get 5-10 plants i wont be buying again :P,
