i plan to ferment both ales and lagers in my basement this year. as the ambient temp will likely be in the upper 40s to low 50s, i am planning on obtaining a heating mechanism of some type. because i wont be conducting fermentation inside of a refrigerator/chamber of any type what do you think i should be using as a heating source? i have research some and seen a multitude of options including a heating belt, reptile wrap, a electric blanket, and an actual heating pad (the brew pad that you place the carboy on top of).
i have a johnson digital temp controller that i will be using with this. that said, what have you all found to be the best option of those above?
