Yeah, the temperature flux is my biggest fear with this method. I also considered getting some kind of pan for the carboy to sit in, fill it with water, and a towel over it so that the water could wick up it and act as an insulator -- but I'm afraid that would cool it down a lot.
Would the blanket cause it to heat up too much?
FlyAngler - 80 degrees starting point seems a tad high -- has it worked for you?
