made a few mistakes which lead to inefficient cooling as well as a mess to clean up that I hadn't anticipated. My efficiency was a couple percentage points lower than normal, too.
There were a few moments of panic, though. Three of my neighbors have automatic sprinkler systems and they all kicked on at some point during the session. The noise of those sprinklers made me think I had sprung a leak somewhere, so I would scramble to figure out what was wrong every time one of them kicked on.
But, all in all it went fairly well and I've got 5 gallons of APA in the fermentation chamber.
