Vivosun 20" x 20.75" Seedling Heat Mat w/ Dual Digital Thermostat, 2-Pack
A single heat mat caps how many trays you can start at once. Cold, uneven root zones slow germination and leave you with patchy, staggered seedlings. The Vivosun 20" × 20.75" Seedling Heat Mat 2-Pack doubles your heated propagation area to more than 830 square inches. Each mat pairs far-infrared heating with its own dual digital display thermostat, so you can run two trays at the same temperature or dial in different settings for different crops.
Far-infrared heating spreads warmth evenly across the full 20" × 20.75" surface of each mat. From a typical ambient 68–77°F, each mat reaches 104°F in minutes, with a maximum of 122°F. The dual digital display shows your set temperature and the real-time pad temperature side by side, giving you precise control over your
propagation environment.
Each mat is built from durable PVC and PET film that meets MET safety standards. An IP67 waterproof rating makes it safe in humid grow tents and easy to wipe clean. Double-insulated heating film protects delicate roots from scorching, and built-in overheat protection powers the mat off automatically if temperatures exceed safe limits. It's a dependable choice among
seedling heat mats for growers scaling up their starts.
