Looks sweet. Here are a couple recommendations:

1) Computer fan. You can actually ask for quiet fans that will make practically no sound. And when I say "practically" I mean it's damn close to no sound. You'll still need something in your room that creates ambient sound (i.e. table fan, computer, etc.)

2) If NOBODY can see this you need to do something a little tricky. Odds are somebody will go into that cabinet either being curious or looking for something. Seal the front door. Make it only able to open from the side or the back.

That'll make it, as you say, "superstealth"

Happy growing! ^_^
