What is the best, easiest, and most inexpensive way to control the fermentation temperature? I just got into this and I do not have a lot of money to spend on equipment. It will be summer time soon and my house will only be cooled down to about 78-80 degrees (can't afford high electric bills). I don't mind purchasing a used mini fridge off craigslist but, I have a very picky wife who will throw a fit if I build a large wooden contraption such as a fermentation chamber to put in the garage or the spare bedroom. Will a mini fridge accomodate a fermentation bucket without modification? Would that even be a good idea? Any advice is much appreciated.
