Ok, so here's my question. I currently have a small ferm chamber that I use a brew belt and ice bottles for heating/cooling with an STC-1000 based temp controller. As I live in an area where the summers get hot, and I am fermenting in my garage (only choice), I occasionally have a problem with the ice bottles lasting thru a workday. I was thinking of getting a chest freezer, but one big enough to do more than one bucket at a time. Here's the real question - how would I do that with just one controller/probe that normally gets taped to the side of the bucket under a sponge for insulation? Or do I just get like a 5 cuft unit and stick to one bucket at a time?
