So I am going to build a fermentation chiller this week/weekend. The box seems pretty easy & straightforward. My question is about the thermostat. I am going to use an electric thermostat and take the thermistor out, attach it to a longer wire so I can apply it to the side of the fermenter. It seems like a lot of these builds are measuring the ambient temperature in the inside of the box. I want to tape the thermistor to the outside of my bucket to get the temp of the wort, as I know it is usually hotter than the ambient temp. Any thoughts or recommendations? I will be brewing my third batch this weekend, so I am still a noob. Just getting tired of the ice bottle waterbath in the cooler (plus it has huge temp swings).
