Hey all, I've got 6 plants (planning to get rid of four of them when I figure out the sex), 3 weeks old, growing under CFLS. I noticed they've already started smelling, so I'm guessing it will get a lot worse when they flower. Right now I grow them in an open closet within a walk-in wardrobe type room in my small apt, but I realize I will need to close off the growing room because of the increasing smell. That is, the smell doesnt bother me, but I'm afraid it will seep out into the apartment building and make the neighbours suspicious. So I'm looking for a cheap way to conceal the smell. I've read up on DIY carbon scrubbers, but I don't understand how it works. Right now I have a PC fan as an exhaust, even though the door of the cabinet is open. I am planning to close up the cabinet with a door with a passive intake. But even if I make a DIY carbon scrubber for the exhaust (a PC fan), won't the smell seep out of the passive intake, which will just be a hole in the wall? Will i have to smell-proof the passive intake too? Can someone explain?
