Dude Seriously ?My grow room is 1' by 3' (small I know!) and the smell is concerning me because my parents don't even know I grow. My operation is being held inside my closet and its very stealthy and compact . I have a 2' air blower/purifier and a ghetto carbon filter using the cotton filter - bag - and activated carbon and a fan blowing into the carbon filter. I only have 2 plants and it still smells with all that.....What can I do? I obviously can't cut any holes in the wall !
