VIVOSUN 10" x 20.75" Seedling Heat Mat w/ Dual Digital Thermostat - 3 Pack

The dual display allows you to see both your target temperature and the actual, real-time temperature of the heat mat simultaneously. This eliminates guesswork and ensures your seedlings are in the precise environment you intended, leading to better, more consistent germination.

This is a 3-pack, so you will receive three individual 10" x 20.75" seedling heat mats, each with its own integrated dual digital thermostat controller.

Most seeds germinate best in a temperature range of 70-85°F (21-29°C). These heat mats are designed to gently raise the root zone temperature about 10-20°F above the ambient room temperature to hit this ideal range. For more detailed information, check out our beginner's guide to indoor growing.

Yes. While ideal for seed starting and cloning, these mats are also great for home brewing (maintaining yeast temperature), fermentation projects like kombucha, or providing gentle warmth for reptile terrariums.

These heat mats are a foundational piece of the VIVOSUN ecosystem. They are perfectly sized for standard 1020 propagation trays and fit seamlessly inside a VIVOSUN grow tent, providing the ideal start for plants that will eventually be moved under a VIVOSUN LED grow light.
