79, tisk tisk... Some folks will say keep your dor away from the AC vents because the air is dry. I say, if it's a good box, and it's tight, and you have a humidifier in it. Place it in proximity to an AC vent with the air blowing on the box. Not directly in front, maybe put a foot or so between the box and the vent? and experiment by moving it closer and farther. Then don't run your fan constantly, i.e., the fan only comes on when the AC kicks on. That will do the trick. The only risk is, if you're not properly humidified, you can dry out because air coming out of the vent is pretty dry. But if you keep an eye on your humidity, and have a good box, you should be fine. That technique worked for me before I built a climate controlled box.
