Cool, I'll go get a 25 watt bulb. The temperature of the room the box is in ranges from about 70 - 80 degrees at the moment, and the humidity of the room is between 50 and 65%. I had another temperature spike today, got home and the temp was at 108 degrees! Was a hot day outside too... I almost cried, but candled tonight and the little troopers are moving around in there so they're definitely not dead...
