Measures 9″ x 19.5″, this 17 watt Seedling Heat Mat is normally used to germinated seeds, but works great as a mushroom spawn incubator heat pad. Raises temperatures 10-20deg above ambient.
Use in conjunction with the Hydrofarm Electronic Thermostat Controller for precise temperature control in an insulated space such as a small box or cooler. An easy and inexpensive way to incubate your spawn!
Placing your spawn bags or jars directly onto the heat mat may cause spawn to dry excessively.
