This is really cool, I like how stealth it can be. I've been thinking about using a fridge for a grow, and leaving the compressor and coils in tact, and jacking with the temperature setting so that the fridge will actually still run and keep the environment at a constant 75 degrees...although i haven't quite figured out how the air exchange would work in a system like that...maybe use a little co2 tank in there as well and just keep it sealed if possible.
