Jump Start Soil Heating Cable, 48'

Thermostatically Controlled Bottom Heat for Any Bench Layout, 48 ft

Cold growing media slows germination and root development even when air temperature looks fine, and a rigid heat mat doesn't always match the shape of an irregular bench or propagation area. This 48-foot soil heating cable lays out flexibly to fit almost any growing area shape, warming up to 12 square feet while a built-in thermostat holds the range most propagation stages call for.

With a thermostat that maintains 77 to 85 degrees Fahrenheit and water resistant construction, this cable suits growers who need bottom heat across a custom-shaped bench rather than a fixed rectangular mat.

Key Features & Benefits

• Heats Up to 12 Square Feet — covers a meaningful propagation or germination area from one cable.
• Built-In Thermostat — maintains 77 to 85 degrees Fahrenheit without manual adjustment.
• Water Resistant Construction — rated for 140 watts at 120 volts, 1.17 amps.
• Flexible 48-Foot Cable — lays out to fit an irregularly shaped growing area.

Who Should Use This Heating Cable

This cable fits growers who need thermostatically controlled bottom heat across a growing area that doesn't match a standard rectangular heat mat, since the flexible cable can be routed to fit the actual bench or propagation space.

About Jump Start

Jump Start builds propagation equipment, including this soil heating cable, designed to bring thermostatically regulated bottom heat to growing areas that a fixed heat mat doesn't fit well.

Frequently Asked Questions

How much area does this cable heat?

It heats up to 12 square feet of growing area. That's enough for a meaningful germination or propagation bench without needing multiple heat sources.

What temperature does the built-in thermostat maintain?

The thermostat is designed to maintain a range of 77 to 85 degrees Fahrenheit. That range supports faster germination and root development without manual temperature adjustment.

Is this cable safe to use where moisture is present?

Yes, it has water resistant construction, which matters given how much moisture is typically present around a propagation area. It draws 140 watts at 120 volts (1.17 amps).

How long is the cable, and why does that matter for layout?

It measures 48 feet, and its flexibility lets it be routed to fit any growing area shape rather than being limited to a fixed rectangular footprint. That makes it a better fit than a mat for benches with an irregular layout.
