Hey all,
So I ran a few brews through my chamber and it worked great but I decided to change my design a little. I replaced my previous heating element which was a 90W flood light bulb with a 60W ceramic heater. I am not reaching my temperature or the chamber is just not as responsive when heating. Can anyone give me a hand in adjusting my chamber settings?
Here are my settings:
