Heat Mat 10' and Medium Controller



SKU: 04475-00-00

Includes (1) 10' x 11" heat mat (1320 square inches), a temperature controller and probe. Add up to (4) 10'. Heat mats to this controller. Start Seeds like the Professionals! The controller for each of these heat mat systems allows you to vary the temperature from 40 to 100 °F. (one degree increments), as exact temperatures are the key to good seed germination. Plug the 11" wide heat mats into the controller, place the copper probe in the soil, check the suggested soil starting temperature listed on each packet of Harris Seeds, and set the controller dial accordingly. Use a power strip when adding more than two heat mats per controller. Each kit is completely safe and waterproof, and properly grounded. This professional quality system lasts you for years!


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."
