The rheostat I have can operate two heat devices so that shouldn't be a problem. The next size up heating pad is about a third of the size of the tote. I was going to get that one but the package said only the mini one was safe to use with plastic.


I am going to get a thermostat, I'll probably order one online today since I can't find any place around here that sells them. I just got the rheostat at a temporary fix. Also, I'm using an accu-rite temp/humidity gage, seems to work very well so far.
