Man, you just can't imagine the smell that 2 or 3 or 4 12 inch tall plants can make, especially good indica plants. They don't call it skunk weed for nothing. BUT, we grow in a spare bedroom closet, and we keep the bedroom door CLOSED and when the repairman came to the house, he didn't smell anything. You can vent the room, or open a window(if you don't have nosey neighbors) or buy a deodorizer, or a small room air freshener. It is sort of like eating _ _ _ _ _, you don't let the smell slow you down !
