VIVOSUN 20 in. x 20.75 in. Seedling Heat Mat and Digital Thermostat Combo Set

The VIVOSUN professional heat mat maintains sweet-spot temperatures around 68-86â„?20-30â„?, which is perfect for start seeding and cutting propagation. Made of high-quality PVC material, it is wear-resistant and durable to use. With the radiate far-infrared light wave, this seeding heat mat makes the heat source softer and provides enough heat, which can be heated up to 40 ℃（104℉）at an ambient temperature of 20-25 ℃（68-77℉）in minutes. We recommend using it with the VIVOSUN thermostat controller and humidity dome.
