I sit my fermenter on a closed cell foam pad. My reasoning is the walls of the freezer will be colder than the inside air temp when the compressor is running. The yeast cake sits on the bottom of the fermenter so I don’t want it touching the cold bottom of the freezer. What were we talking about again? Oh yes, I don’t have condensation issues in my fermentation freezer, but have them in my keezer and have to use damp rid.
