Jump Start 107W Seedling Heat Mat - 48" x 20"

The 48" × 20" surface fits approximately four standard 10" × 20" propagation trays, like those included in the Jump Start 72-Cell Hot House Kit, end-to-end along the length of the mat. This makes it an efficient choice for growers running multiple tray cycles simultaneously on a single bench run.

The mat can be plugged directly into a 120V outlet without a thermostat, but at 107W a thermostat is strongly recommended. Without one, the mat runs at continuous full output — which can overheat the root zone. The Jump Start Digital Temperature Controller for Heat Mats is fully compatible and sold separately.

All Jump Start mats share the same multi-layer waterproof construction — the differences are surface area and wattage. The 17W seedling heat mat and 45W square mat suit smaller setups, while this 107W model is built for growers running four or more trays simultaneously.

Yes. The heavy-duty multi-layer build and waterproof construction are specifically engineered to withstand the rugged conditions of commercial greenhouse propagation. UL listing and the robust 107W output make it an appropriate choice for professional propagation operations.

This mat does not feature daisy-chain connectors — that functionality is specific to the Jump Start 140W Commercial Seedling Heat Mat and its Modular Add-on. To run multiple 48" × 20" mats, each unit requires its own outlet connection. For unconventional layouts, you might consider the Jump Start 48' Soil Heating Cable.

Yes, the mat is UL listed for continuous operation. When paired with a thermostat, it will cycle on and off automatically to maintain your target temperature rather than running at full output around the clock — which is the recommended approach at 107W for both energy efficiency and precise root-zone temperature management.
