Why do we care about fermentation temps? What happens if our ferment gets too hot? Is it a problem if your wash is too cold? In this video, I am going to go over all these questions. Then I will offer a few solutions to actively control the temperature of your fermenter using light bulbs, blankets, heaters, aquarium heaters, fridges and of course the mighty STC-1000. If you do not know what the STC 1000 is stay tuned. These things are awesome!
