I don't have a good way of controlling fermentation temps, normally I just stick it in the closet and crank up the a/c. I've always assumed the carboy is about 5 degrees above ambient. But on my current brew I decided to check the temp of the bowl of starsan my blow off tube goes into, which is a couple degrees below ambient. Now, I know that while fermenting, there will be a certain amount of heat generated, so as long as I take this into account, will taking the temp of the starsan be a more accurate way of monitoring the temp? There is probably a bit under 1/2 a gallon of starsan and my carboy is holding 5 gallons but I don't want to open up my carboy for a temp/gravity reading until fermentation has died down.
