Heat Mat High Temperature Agritape



SKU: 70088-00-00

Great for Seedless Watermelon!

This heat mat reaches higher temperatures than a standard heat mat, allowing you to germinate seeds in cool areas and achieve warmer soil temperatures. This mat is an excellent tool for small growers who start seeds in cool basements rather than greenhouses. In air temperatures cooler than 55° F, this mat warms the soil enough for proper germination of heat-loving crops like tomatoes, peppers, and melons. Seedless watermelon growers love that this mat easily reaches the 90° F soil temperature that triploid melons require for germination. Mat measures 11" wide by 4' long, perfect for starting two flats of seeds. Mat is designed for use with your existing thermostat or the one included in our money-saving Heat Mat and Thermostat combo see item 70077.

Note: Designed for use in air temperatures below 55° F or when soil temperatures over 80° F are needed. To avoid soil drying, germinate seeds in 128 cell plug trays or in larger pots or cells. Use a standard heat mat for proper germination in smaller cell sizes and all other temperature conditions.


Harris Seeds began operation in 1879 from the efforts of Joseph Harris, who was successful in selecting only the highest quality vegetables and grains. The company gained popularity because of his basic business philosophy: "Offer customers a quality product at a fair price and they will return." READ MORE
