Forgive me if this is answered in another post. I'm interested in how others handle this. I currently have a dedicated fridge and Johnson controller for fermentation. I tape the probe to my carboy with a towel to insulate so I can measure wort temp during fermentation. This does fine for cooling, but now the issue is heating. My last 2 batches began dropping below set point after initial activity. Temp dropped to the low 60's although initial set point was 67. Last night I put a heating pad in the fridge, near the carboy and this seemed to help warm things up. But I don't have a way to regulate this like I do with my fridge. Any ideas or thoughts would be appreciated. Am I on the right track or not? Thanks, Steve
