How large is the light you plan on putting in your armoire? I used to grow in a box and they can get a bit hot (used a 600w hps in mine). If you\'re naturally venting into the room using your home\'s HVAC system, you may want to think about the location of the thermostat and the A/C\'s ability to know that the room where you box is located is getting warm.
