This heat mat will add approximately 10o C if left on continuously. If too warm there are heat dispersion plugs in the pack that will enable you to reduce the temperature. We find these need to be used in conjunction with a timer if not using a thermostat. A plug in thermostat is available to control the heat of one or several mats. Packages of heat mats with thermostats are available. Easy to use. Will heat propagation trays or pots.
