Super Sprouter 12" x 48" Heat Mat



SKU: 40659-00-00

Easy to use, with twice the growing space! Give your seeds and seedlings the root zone heat they need for consistent germination and vigorous growth. This durable, easy-to-use heat mat elevates root zone temperature 10° to 20° above the ambient air temperature. 12" x 48" mat offers ample room for two standard seedling trays set end-to-end, and it provides enough warm surface area to heat the trays' edges thoroughly. Use one mat, or connect up to 10 mats using a simple, safe daisy-chain mechanism, and run them with one power cord. Wipe mat clean and roll for storage. Two mats fit great on our 12 and 16 tray light stands. For more precise temperature control, pair this mat with the Super Sprouter Thermostat.


The Harris Seeds company began catalog operation in 1879. It evolved from the efforts of Joseph Harris who was extremely successful in the selection of superior strains of vegetables and grains. The company became wildly popular because of his basic business philosophy - "Offer my customers a quality product at a fair price and they will return."
