Super Sprouter Thermostat 

With its precise settings, the Super Sprouter Thermostat lets you contol the seedling heat mat temperature to easily dial in the ideal seedling germination temperature. 

Also works well for accurate growing medium temperature control with plant cloning, or use it for growing temperature sensitive crops (mushrooms).

This seedling heat mat thermostat is designed to be used with the Super Sprouter Seedling Heat Mat, but it is compatible with any other brand of heat mat.

Super Sprouter Thermostat is easy to use - simply plug the mat into the thermostat then place the temperature probe into your soil or other growing media.

Plugs into any standard 120 volt grounded outlet.
