and as far as odor control. all I know is my little guys stink up the room when the doors remain shut for long periods of time but its not really stinky, just a little smell that most people prob. wouldnt even recognize. It's not too bad, a little air freshner or dryer sheets on top of the vent hole help tremendously. When they actually start budding it might be a different story but for now its not bad. hope this helps.
