Seedling Heating Mats - Thermostat

Consistent warmth at the root zone can make all the difference for seed germination, and this seedling heating mat with thermostat delivers gentle, even heat to encourage strong early growth. Designed to raise the root area temperature to the optimal range for many crops, it helps speed germination and improves success rates for vegetables, herbs, flowers, and other plants, especially in cooler growing environments.

Adding a thermostat to your Seedling Heating Mat allows you to regulate and maintain optimum growing temperatures.

• Provides constant temperature by adjusting heat levels as the ambient air and your soil temperature changes.
• Invaluable if your mat lacks temperature control capabilities.
• Digital display, 3-prong ground plug.
• Compatible with all heat mats.
• Temperature range 68-108°F, precise to +/-2°F.

The mat’s durable, waterproof design and insulated wiring provide safety and long-lasting performance, making it ideal for greenhouses, propagation areas, and indoor garden setups. With the thermostat ensuring precise control, you can cater to the unique needs of heat-loving crops or maintain steady temperatures for more delicate seedlings. Beyond seed-starting, it can also be used for homebrewing projects or maintaining warm conditions in pet enclosures and terrariums.
