This thermostat is an electronic temperature control device that allows you to select and maintain optimum temperatures. Has an easy to read dial setting (color coded) from 60 to 100 F. Equipped with two LED lights. One shows the power is on and the other that current is flowing out to the heating pad. If the “heater” is on for more than 5 consecutive hours this would indicate that desired temperatures are not being reached. Or it's pretty darn cold out there! This unit along with our Heating Pads or Heating Mats are only designed to raise the ambient temperature 10-20  degrees F.  The temperature sensing probe is contained within a suction cup that sticks onto the side of the fermenting containers.

We recommend the Seedling Mat (9 x 19.5) which is set at 17 watts for warmer climates and for cooler ferments in the 60-80 temerature range.. This cooler range works well for people who keep their homes warmer and for adding just a bit of warmth to kombucha tea, some yogurts and kefir and also for seedlings and Sprouts like Wheatberry  Grass. Our Blue Heating Panel (11.5 x 11.5) is set at 25 watts and is suited for colder climates and for ferments in the higher range.  80-110 F. Most yogurts are in this range in the range and kombucha tea and kefir and wines and vinegars. Ideal situtations depend upon the volumne of the ferment as well as the area exposed to evaportion and ambient temperatures.
