So I'm already planning my second batch of beer as my first one has turned out okay. I obviously want to get better and better at this and realize besides sanitation, temperature control is key as well. So if I went out and bought a chest freezer to turn into a fermentation chamber, would all I need to buy besides the freezer are some Johnson Controls? I don't have a ton of time to devote to making a fermentation chamber from scratch so this sounds like it would be the best option for me. I'm sure I could lager in it as well correct?
