About This

• Longer Single-Row Coverage: The 11" x 36" size gives growers more heated surface than a standard single-tray mat, making it useful for multiple small trays, longer propagation setups, and grow shelves.
• Root-Zone Warmth for Seed Starting: Warms the root area about 10-20 degrees F above ambient temperature to help support seed germination, early plant growth, rooting cuttings, and propagation success.
• Flat Thin-Film Heating Mat: Designed to lay flat and distribute warmth across the mat surface, helping reduce cold spots, tray imbalance, and the clutter caused by using several small mats together.
• Built for Seasonal Reliability: Made in USA with durable materials and UL-recognized components for indoor gardeners, greenhouse growers, hydroponic users, and serious home growers.
• Thermostat-Compatible Setup: Use with a seedling heat mat thermostat when precise temperature control is important, especially for delicate seedlings, sensitive cuttings, hydroponics, or cooler rooms.
