Hydrofarm JumpStart Digital Temperature Controller for Heat Mats - 68-108F - 8.3A / 1000W

Hydrofarm JumpStart Digital Temperature Controller for Heat Mats - 68-108F - Precise Root Zone Temperature Management

The Hydrofarm JumpStart Digital Temperature Controller allows growers to select and maintain an exact root zone temperature for seedling and cutting propagation, rather than relying on the fixed output of a standard heat mat. Set your target temperature anywhere in the 68-108 degree F range, and the controller automatically cycles the connected heat mat on and off to maintain that exact setpoint. Compatible with all Hydrofarm heat mats and many other brands of heat mats. The included temperature probe monitors actual growing media temperature, and an illuminated indicator light shows when the mat is actively heating. 3-prong grounded plug. Celsius or Fahrenheit readout (hold the up or down button to switch). Rated for up to 8.3 Amps / 1000 Watts - handles multiple mats on a single controller when within the rated amperage limit.

Key Features & Benefits

• Precise Temperature Control - 68-108 F: Set an exact target temperature for your root zone rather than relying on a fixed mat output - critical for crops that require a specific germination or rooting temperature to perform optimally.
• Temperature Probe Included: The probe monitors actual growing media temperature at the root zone and feeds that data back to the controller to maintain your target setpoint accurately.
• Compatible with All Hydrofarm Heat Mats: Works with all JumpStart and Hydrofarm heat mats as well as many other brand heat mats - a single controller can manage your entire heat mat setup.
• Illuminated Indicator Light: Visual indicator shows when the heat mat is actively heating - lets you confirm the controller is cycling correctly at a glance.
• 8.3A / 1000W Capacity: High amperage rating supports running multiple heat mats through a single controller simultaneously, up to the rated load limit.
• Celsius or Fahrenheit Display: Toggle between C and F readout by holding the up or down button - use whichever scale your growing operation prefers.

Who Should Use This

The JumpStart Digital Controller is an essential upgrade for any grower who wants to dial in a specific root zone temperature rather than accepting the fixed output of an uncontrolled heat mat. Particularly valuable for crops with narrow germination temperature windows, operations running different crop species simultaneously at different target temperatures, or anyone who has struggled with overheating during warm ambient conditions. Compatible with virtually all heat mat brands, making it a versatile addition to any propagation setup.

Compatibility

Compatible with all Hydrofarm JumpStart heat mats and many other heat mat brands. Maximum load capacity: 8.3 Amps / 1000 Watts - do not exceed this limit when connecting multiple mats. The included temperature probe should be placed in the growing media or under the propagation tray to monitor actual root zone temperature. 3-prong grounded plug for standard 120V household outlets.

Frequently Asked Questions

What temperature range does this controller support?

The JumpStart Digital Controller supports a temperature range of 68 to 108 degrees F. Set any target temperature within this range and the controller will maintain it by cycling the connected heat mat.

How do I switch between Celsius and Fahrenheit?

Hold the up or down button on the controller to toggle between Celsius and Fahrenheit display modes.

Can I run more than one heat mat on this controller?

Yes, as long as the combined amperage of all connected mats does not exceed the 8.3 Amp / 1000 Watt rated capacity of the controller.

Where should I place the temperature probe?

Place the temperature probe directly in the growing media or at the surface of the tray above the heat mat to get an accurate reading of the actual root zone temperature your plants are experiencing.
