What do you all think I have a small chest freezer fermentation chamber and the space heater takes up too much room (can only get one bucket in so if I change the heat source I could get another in) so I was thinking of going with some flex watt stuff also the hair dryer could be a good option but my real question is:
Is it better to use direct heat to the fermenter or heat the air?
