Jump Start Commercial Seedling Heat Mat, 60" x 21", 140W

Commercial-Grade Bottom Heat for High-Volume Propagation

A single heat mat only covers so much bench space before a commercial operation needs to add more, and wiring in a separate mat from scratch means a separate cord and thermostat hookup. The Jump Start Commercial Heat Mat is the base unit of a modular, daisy-chainable system that provides uniform bottom heat for hundreds of seedlings or cuttings, warming the root area 10 to 20 degrees Fahrenheit over ambient temperature across a 60 x 21 inch, 140 watt mat.

This base unit lets you daisy-chain up to 4 MTMDA add-on units to expand your growing area, and connects to the Digital Heat Mat Thermostat (MTPRTC), sold separately, for precise temperature control.

Key Features & Benefits

• 60 x 21 Inch, 140 Watt Base Mat — sized for large propagation areas.
• Starts the Daisy-Chain — the unit every MTMDA add-on mat connects back to.
• Rugged, Waterproof Connectors — built for repeated greenhouse use.
• Warms Root Area 10-20°F Over Ambient — uniform heat across the whole chained system.

Who Should Use This Heat Mat

Commercial growers who need uniform bottom heat across a large propagation area, with room to expand as the operation grows.

About Jump Start

Jump Start, a Hydrofarm brand, builds this modular heat mat system as its commercial-scale propagation offering, engineered so a grower starts with one base mat and expands bench coverage by chaining additional units onto it as the operation grows.

Frequently Asked Questions

How many add-on units can connect to this mat?

Up to 4 MTMDA add-on units can daisy-chain to a single MTMDU base unit. That allows a bench to grow from one mat up to five total mats on the same chain.

What size is this mat?

60 inches by 21 inches, drawing 140 watts. It's built as the base unit that add-on mats connect to.

Is a thermostat included?

No, the Digital Heat Mat Thermostat (MTPRTC) is required for precise control and sold separately. Without it, the mat still runs, but at its fixed warming output.

How much does this mat warm the root zone?

10 to 20 degrees Fahrenheit over ambient temperature. That range is consistent across the whole daisy-chained system, add-on units included.
