Bought a chest freezer to replace the fermentation chamber I had built. I am having trouble keeping the temp at a nice steady temp. I have the temp set to 19 C with a .5 degree difference. The freezer kicks on at 19.5 and sends it all the way down 18 if no heater is turned on. If the heater is turned on, it clicks on at 18.5 and sends it all the way to 20.5. Then of course the freezer turns on and we start the process all over, with a never ending back and forth. Now I wall say the heater I am using is probably too big but I am not sure what else to use. Any suggestions? I have heard of using light bulbs or like utility light.
