Here most simply put whatever they took out of their kitchen in the garage. That said - you can trick the fridge and freezer into running with an Inkbird controller like
this. Plug the fridge into the "cooling" section and the inkbird into the wall. Set your temp. I have my freezer set as cold as possible and the inkbird keeps it where I want for fermentation. I put a jar of water with the inkbird probe in it in there. (I also have a warming side/cycle but that's because I'm trying to hold temps to a specific degree and do ramp ups etc - not for keeping ice cold or beer cold)
