VIVOSUN 20" x 20.75" Seedling Heat Mat w/ Dual Digital Thermostat - 2 Pack

Most seeds germinate best between 70–85°F (21–29°C). The thermostats let you dial in the right temperature for each plant type to improve germination rates. For more on dialing in your environment, see our guide on grow room temperature and humidity.

Far-infrared heating responds quickly. In a room with an ambient temperature of 68–77°F, each mat reaches 104°F within a few minutes.

Yes. The mats are designed for seedling trays and flats to sit directly on the surface. Double-insulated heating film delivers gentle, even warmth that promotes germination without scorching delicate roots.

Yes. Each mat carries an IP67 waterproof rating and meets MET safety standards, making it suitable for grow tents and other high-humidity propagation spaces. Built-in overheat protection also shuts the mat off automatically if temperatures exceed safe limits.

Always unplug the mat first. Thanks to the waterproof surface, you can wipe it down with a damp cloth. Avoid abrasive scrubbers and harsh chemicals to extend the life of the mat.
