FAQs

What is the main advantage of the dual digital display?+

The dual digital display allows you to see your target temperature and the mat's actual current temperature at the same time. This eliminates guesswork and provides instant feedback, ensuring your seedlings are always in the optimal environment without needing a separate thermometer.

How quickly does the heat mat reach its target temperature?+

Thanks to its far-infrared heating technology, the mat heats up very quickly. In an environment with an ambient temperature of 68-77°F (20-25°C), it can reach 104°F (40°C) within just a few minutes.

Can I place my seedling trays directly on the mat?+

Yes, absolutely. The mat is designed for seedling trays, flats, or small pots to be placed directly on its surface. For best results and improved airflow, using a humidity dome on your tray is also recommended to trap warmth and moisture.

Is the heat mat safe to use in a humid environment like a grow tent?+

Yes. The mat has an IP67 waterproof rating, which means it is protected against dust and can withstand being submerged in water up to 1 meter. This makes it perfectly safe for the high-humidity environment of a grow tent or propagation room. Maintaining the right climate is key, as explained in our grow room temperature and humidity guide.

How does this 48" mat compare to smaller options?+

This 48" x 20.75" mat is designed for large-scale or commercial propagation, allowing you to heat multiple standard 1020 seedling trays at once. If your needs are smaller, VIVOSUN also offers more compact options like the 20" x 20.75" heat mat, which is ideal for hobbyist growers or smaller batches of clones and seedlings.
