SUNCORE H5 Waterproof Seedling Heat Mat with Digital Thermostat Controller – 20" x 20.75"

SUNCORE H5 Waterproof Seedling Heat Mat with Digital Thermostat Controller – 20" x 20.75"

Give your seeds and cuttings the consistent warmth they need with the SUNCORE H5 Seedling Heat Mat, a precision-controlled heating mat designed to improve seed germination and plant propagation. Measuring 20" x 20.75", the mat provides even, adjustable heat across the growing area and includes a digital thermostat controller for precise temperature management.

With an adjustable temperature range of 32–122°F (0–50°C), the H5 allows you to set your desired temperature while the digital controller displays the mat's current temperature in real time. The mat can warm the rooting area to as much as 20°F above ambient air temperature, providing a warmer environment for seeds and developing roots.

Digital Temperature Control

The connected digital thermostat gives you precise control over the mat's temperature and displays the real-time heating mat temperature. Set the desired heat level and monitor changes as they occur, eliminating guesswork when creating the appropriate temperature for different seeds and propagation projects.

Even Far-Infrared Heating

The SunCore H5 uses innovative far-infrared heating film to distribute warmth evenly across the entire mat. Compared with traditional wire-coil heating, the film provides a softer, more consistent heat output designed to help prevent localized hot spots and scorching.

Waterproof IP67 Construction

Built with durable quad-layer PVC, the heating mat is flexible, wear-resistant, easy to wipe clean, and convenient to roll for storage. The mat features an IP67 waterproof rating, with sealed seams designed to help prevent water and dust from entering.

The waterproof protection also extends to the power-cord connection, which is specially sealed to help protect against electrical damage caused by moisture.

Ideal for Seed Starting & Propagation

The SUNCORE H5 is designed to provide supplemental warmth for:

• Seed germination
• Seed starting
• Plant propagation
• Rooting cuttings
• Indoor growing
• Basements
• Terrariums
• Greenhouse dome setups

For seed starting, pairing the heat mat with a humidity dome can help create a warm, humid environment that supports the germination process.

Versatile Heating Applications

Beyond seed starting and propagation, the SUNCORE H5 can also be used for home brewing, beverage fermentation, and reptile pet enclosures, making it a versatile temperature-control mat for a variety of indoor applications.
