I read somewhere of someone using a hairdryer in a chest freezer to control fermentation temps. It was connected to a temperature controller. Personally I think this is a great idea for a few reason; first of all we have any extra hair dryer so I wouldn't have to purchase anything, rather than just heating the air the fan in the hair dryer moves the hot air around, also the hair dryer has a built in ground fault so there is a bit of safety built in.
Any reason I shouldn't use a hair dryer?
