Ok--cant find the answer to this one on a search. I got a wild hair and decided to brew two beers at once. One is the normal 5.5gallon in a plastic ale pail. The other is a 4.5gallon in a 5gallon glass carboy (I know its going to blow off and that is taken care of). Both are using US-05. I have one temp controller and they are in the same fridge. My question is--which should I attach the temp probe to. In my mind I can logically justify putting the temp probe on either one but just need some advice from the experts so they ferment correctly. Thanks and have a good day.
