The 9" x 19.5" 17 watt Seedling Heat Mat with Digital Thermostat Controller. Used to germinated seeds, but works great as a mushroom spawn incubator heat pad. Use heat mat in conjunction with the included thermostat for precise temperature control.

Place your heat mat or pad in the bottom of an insulated cooler, insert the probe and place it near your spawn bags or jars. Set the digital temperature controller to desired temperature and close lid. Spawn needs fresh air, so be sure to fan the incubator if it remains closed, or provide small exhaust holes for fresh air to enter and leave.

Placing your spawn bags or jars directly onto the heat mat may cause spawn to dry excessively.
