Does anybody know if those fermenter heaters that wrap around the outside of your bucket/carboy work. If so would it work to keep it at around 60-70 deg in a cool garage thats around 50 deg?
That's a big enough temp differential that you'll end up wasting a lot of power if you don't insulate your carboy. Why not ferment in your living quarters for an ale and ferment a lager in the garage?
