Precision Fit for 1020 Trays: The 11" x 22" size is designed for standard 1020 seed trays and compact indoor shelves, helping reduce wasted space, overhang, and bunching compared with generic mat sizes.
Faster Germination and Root Growth: Warms the root zone about 10-20 degrees F above ambient room temperature to support seed starting, plant propagation, rooting cuttings, and healthier early-stage growth.
Thin-Film Heating Technology: Built with a flat-laying heated film design that helps spread warmth across the mat surface, giving trays a cleaner setup than curled rubber-style pads or messy small mat layouts.
Made in USA Durability: Manufactured in the USA with durable materials and UL-recognized components for growers who want a reliable propagation mat for seasonal seed starting, indoor gardening, and greenhouse use.
Thermostat-Ready for Better Control: For delicate seeds, cuttings, or temperature-sensitive plants, pair with a seedling heat mat thermostat and humidity dome for more precise soil temperature management. Thermostat not included.
