I’m a newbie - brewed my first a few days ago and it’s now fermenting. I just discovered that I’m going to want to start trying to keep my fermenters in a temp range. I found this on Craigslist and wanted opinions on if you think this will work. The dimensions tell me it would hold one carboy - just pull the shelves out. The seller of this item says it doesn’t get very cold. I only need it to cool down no more than 10 degrees during the summer.
