It's just a mini fridge I found on craigslist for $35 yesterday. I cleaned it up today and cut out the plastic panel on the inside of the door so I can close it with my fermentation bucket inside. I plan on keeping it in my garage, so I still have figure out the best way to get some heat inside it so I can brew in the winter. I still have to get a temp controller. Any suggestions on what temp controller to use, and what's the best way to heat it during the winter?
