A few years ago a friend gave me a red bull cooler, the upright "can" style like you'd find in a gas station. I'm thinking about removing the cooling fans and using them to build a fermentation chamber. Has anyone here ever done that? Does anyone have advice on it?
Also, I'm looking at using a shipping crate from my work, insulating it of course, as the body of the chamber...are there recommended sizes, insulation materials, etc.?
