Root Radiance Heat Mat - 20 x 20.75-in - 46W - 120V

Steady Root-Zone Warmth for Seedlings and Cuttings - 20 x 20.75 in

Cool media slows germination and delays rooting. This seedling heat mat sits under your trays and warms the root area to 10 to 20 degrees over ambient temperature. That steadier warmth helps seeds start and cuttings establish more reliably.

At this size, the mat suits growers who start seedlings or propagate cuttings regularly in a greenhouse, nursery or indoor space. It covers two 10 x 20-in propagation trays at once, so one mat and one outlet handle a full batch.

Key Features & Benefits

• 10 to 20 degrees over ambient — warms the root zone to support germination and rooting.
• Fits two 10 x 20-in trays — one mat covers a full propagation setup.

Frequently Asked Questions

Q: How much warmth does it add?
A: It warms the root area 10 to 20 degrees over ambient temperature. Actual results depend on room conditions and what sits on the mat.

Q: Which trays fit?
A: It fits two 10 x 20-in propagation trays side by side. Other tray sizes may not cover the mat evenly.

Q: Is it safe around moisture?
A: It is water resistant, which suits propagation areas. Water resistant does not mean submersible, so keep the cord and plug connection dry and away from standing water.

Q: What does ambient temperature mean?
A: Ambient temperature is the temperature of the air in the room or space. The mat raises the root-zone temperature above that baseline.

Q: Does it include a power cord?
A: Yes, it includes a 6 ft 120V power cord. Plug it into a suitable outlet within reach of your propagation area.
