Can you link the redit article? I've had a heck of a time with my Aubrin PID's wildly fluctuating temps, issues where I set the temp and the RTD temp will just scroll. etc.
I can agree with insulating it well, I just never had the accuracy of simply taping it with out some bubble wrap etc. Just saying a thermowell works nicely if you don't mind spending 15$. I just got tired of having to tape something up. By all means if you have a system that works it's golden...
I'm not sure that is accurate, when fermenting we are concerned about the beer's temp during fermentation not the ambient surrounding air. This is why you would have a thermawell in place optimally to monitor the fermentation temperature and adjust as needed. Example my IPA might want to...
I built an electric brewery just about a year ago, live just south of OKC in Bridgecreek, it's based on the Electric Brewery design with parts from electric brewery supply.
