am courious as I feel that because your using the same medium, liquid, that it would better hold temps and have more control compared to using air to cool or warm the wort.
maybe I am just buzzed but am courious what you all think
Sure, I do that. If it's cold, I add an aquarium heater to the water bath but I haven't needed to do that in a couple of years. When it's hot, I add a frozen water bottle to the water bath. I float a floating thermometer in the water bath so I can check the temperatures.
I think this would be most effective when the ambient temperature isn't too much different than the desired fermentation temperature. It's easy to do it in a room temperature of 70 degrees, and add a frozen water bottle or two to get it to 64 degrees. It would be much harder in a warm climate, to get it to 64 degrees and keep it there with an ambient of 90 degrees.
