The Digitial Temperature Controler for Heat Mat can be employed in both gardening and brewing applications.
With a newly improved design, Hydrofarm's Heat Mat Thermostat employs digital technology for greater accuracy. Simply place the temperature probe in the growing media, set the desired temperature and the controller provides power to the heat mat as needed. The Hydrofarm Controller utilizes an illuminated indicator light, 3-prong ground plug, and is compatible with all heat mats.
For brewing applications, attach the probe to the outside of the fermenter. To further isolate the probe from external environmental conditions, tape a cup or paper towels over the probe to maintain a more constant temperature reading for the controller. The Probe fits inside Brew and Grow's Thermowell for further control of fermentation conditions in a refrigerated environment.
