I brewed my first batch of beer not too long ago and I let it ferment in my apartment and, after a few smell complaints I decided that it would be best to let it ferment in my garage across the street. My problem is that my garage temp varies between 70 to 80 degrees during the day and it gets as low as 60 during the night. So I have come to the conclusion that a fermentation chamber is what I need but I have no Idea what I should do... I want to have room for 2 carboys if possible but I only have a budget of maybe $100. Any advice is appreciated.
