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

While standard-size seedling heat mats often max out at one or two trays, the Jump Start Commercial Seedling Heat Mat scales past that constraint with a 60" × 21" surface area. This heavy-duty mat accommodates multiple trays simultaneously, delivering uniform bottom heat across hundreds of seedlings or cuttings in a single run. Like all effective propagation heat, it raises the root zone 10°F–20°F above ambient — the range that measurably accelerates germination rates and rooting success across virtually every crop type.

The real capacity multiplier is the daisy-chain system: this unit serves as the primary mat and supports up to four MTMDA add-on mats connected in series, expanding your heated propagation area to five mats total without additional outlets. Waterproof connectors and rugged construction make the system suitable for demanding commercial environments. A compatible digital heat mat thermostat (model MTPRTC) is required for operation and sold separately — pairing the commercial mat with precise temperature control is what makes consistent, crop-specific results repeatable at scale.

Features

📐
Supersized 60" × 21" Surface

Nearly five feet of heated surface area accommodates multiple trays at once, providing uniform bottom heat across hundreds of seedlings or cuttings per cycle.

🔗
Daisy Chain Up to 5 Units

Connect up to four MTMDA add-on mats to this primary unit, expanding your total heated area to five mats from a single thermostat and outlet.

🌡️
10°F–20°F Root Zone Boost

Raises root-zone temperatures 10°F–20°F above ambient — the proven range for accelerating germination and improving rooting success across a wide variety of crops.

💧
Waterproof Connectors

Rugged, waterproof daisy-chain connectors are built for the wet conditions common in commercial propagation environments, maintaining reliable connections run after run.

⚡
140W Commercial Output

At 140 watts and 120V, this mat delivers the sustained heat output required to maintain consistent root-zone temperatures across a large surface area in commercial settings.

🎛️
Thermostat Required

Designed to operate with the Jump Start Digital Heat Mat Thermostat (MTPRTC), sold separately, for precise crop-specific temperature control.

Frequently Asked Questions

Does this mat require a thermostat, and which one should I use? +

Yes, a thermostat is required for operation — the mat does not have built-in temperature regulation. The compatible unit is the Jump Start Digital Heat Mat Thermostat (MTPRTC), sold separately. Plugging the commercial mat directly into a wall outlet without a thermostat is not recommended, as it will run continuously without temperature control.

How many add-on mats can I daisy chain to this unit? +

Up to four MTMDA add-on mats can be connected in series to this primary unit, for a total of five mats running from a single thermostat and outlet. Each add-on connects directly to the previous mat via the waterproof daisy-chain connectors — no additional wiring or outlets required within the rated load limit.

How many trays fit on the 60" × 21" mat? +

The 60" × 21" surface comfortably fits multiple standard 10" × 20" propagation trays side by side. Depending on tray orientation, you can typically fit two trays across the width and up to three along the length, covering the majority of the mat surface. Exact configuration will depend on tray size and how you arrange them.

Is this mat safe to use in wet propagation environments? +

Yes. The commercial mat is built with rugged, waterproof daisy-chain connectors designed specifically for the moisture-heavy conditions typical in propagation rooms and commercial greenhouse settings. The mat itself is water-resistant and rated for continuous use in these environments when operated with the required thermostat.

What is the total wattage if I run all five mats in a daisy chain? +

The primary MTMDU unit draws 140W. Each MTMDA add-on mat also draws 140W, so a fully loaded five-mat chain totals 700W. Ensure your thermostat and circuit can handle the combined load before connecting the full configuration — always verify the rated capacity of your thermostat and wall circuit against the total wattage of your daisy-chained setup.

Can I use this mat with standard seedling trays and heat mat domes? +

Yes. Standard 10" × 20" propagation trays sit directly on the mat surface, and compatible humidity domes can be used to create enclosed environments, similar to the setup found in the Jump Start 72-Cell Hot House Kit. This combination — bottom heat plus humidity dome — provides the complete microclimate for optimal germination and rooting success.
