Not very stealth eh? Where is it? No attic access I assume b/c u have that pipe sticking out of the door. I would be a little paranoid but thats just me I like to make things look like they belong as much as possible. Plants look good though. I would change the vent system a bit, get rid of the cardboard door and use a real one with some weather-stripping to seal light. Thanks man I love closet grows pretty amazing what you can get out of a space made for clothes!
