I finally got around to plugging my kiln into a Kill-O-Watt meter. It said I use 5 kw per 24 hours. My kiln is about 4x4x3 feet. I use a warm mist humidifier and a 100 watt light bulb. It is a little drafty because this was a "temporary" kiln I built about 5 years ago and I still have it. It is made with 1 1/2 inch rigid foam board. My electric costs about 12 cents per kilowatt/hour.So, for me to ferment for 4 weeks costs me....12cents x 5KW x 28 days= $16.00 (approximate). Not too bad considering I do about 400 leaves at a time.
