I want to build a heated AND cooled fermentation chamber. I have a built in shelf I'm going to use and I'm thinking the bottom will be the chilled portion and the top the heated. The chilled section I think I have a good idea on, will just cut in a mini fridge. I'm struggling with the heated side.
I'm going to wall in the compartment with pink foam board insulation but how should I heat it and control the temp? My basement gets down to 58 degrees so there wouldn't need to be much heat. I have room for 5 fermentors in each compartment
