Hello - I just bought a 7.1 cubic foot chest freezer and an Inkbird ITC-308 2-stage temperature controller. (https://www.amazon.com/gp/product/B011296704/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) I'm using it currently as a fermentation chamber for my first all grain batch. Believe it or not, it's gotten cool enough in this muggy Michigan August that I've needed to use the heater side of the controller. I thought I'd get one of those wrap-around carboy heaters (I ferment in a glass carboy because that's what I have). I realized that if all goes well, I'll be fermenting more than one thing at a time so I put a light bulb with a 45w fridge bulb in there. It seems to work okay, but I had to wrap my carboy in a black garbage bag so the light didn't get to it. Not ideal What other devices do people plug into the heater side of the controller? Small space heater? Reptile heater? Thermonuclear device? I have a little space heater, but I'm not sure that's the best idea. Thoughts?
