Description
Digital Temperature Controller for Heat Mats, Heat Bars & Propagation
The Cultiv8 Heat Mat Thermostat Temperature Controller provides accurate, automated temperature management for propagation heat mats, heat bars, seedlings, cuttings, clones, and other temperature-sensitive growing applications.
Featuring an adjustable 20°C to 42°C temperature range, remote temperature probe, digital display, and temperature calibration, the Cultiv8 Thermostat allows growers to maintain consistent warmth around the root zone without manually switching heating equipment on and off.
With a maximum capacity of 1000W / 4.3A, it can control compatible heat mats, heat bars, and heat rods while providing simple, reliable temperature regulation for indoor propagation environments.

Maintain Consistent Root-Zone Temperatures
Temperature plays an important role in successful plant propagation. Cold growing media can slow seed germination and root development, while excessive heat can create unnecessary stress.
The Cultiv8 Thermostat allows growers to set a desired temperature and automatically regulates the connected heating device according to readings from the temperature probe.
Instead of allowing a heat mat to operate continuously, the thermostat cycles the heating equipment as required to help maintain more consistent conditions around developing roots.
Ideal for Seedlings, Cuttings & Propagation
The Cultiv8 Heat Mat Thermostat is particularly useful for:
- Seed germination
- Seedling establishment
- Cuttings
- Clone propagation
- Propagation domes
- Propagation trays
- Rooting stations
- Indoor nurseries
- Hydroponic propagation
- Temperature-sensitive plants
- Heated growing benches
Maintaining consistent warmth around the rooting zone can provide young plants with a more controlled environment during their most sensitive stages of development.
Adjustable 20°C–42°C Temperature Range
The controller provides an adjustable temperature range from 20°C to 42°C, allowing growers to select an appropriate target for different plants and propagation methods.
This broad range makes the controller useful for more than basic seedling propagation, providing flexible temperature management for a variety of horticultural heating applications.
Digital Temperature Display
The easy-to-read digital interface provides convenient monitoring of the temperature detected by the probe.
Temperature can be displayed in either:
- Celsius (°C)
- Fahrenheit (°F)
This makes the controller straightforward to configure according to individual preference.
Temperature Calibration
The built-in calibration function allows growers to compensate for temperature differences when greater accuracy is required.
This can be particularly useful when comparing the controller's reading against another trusted thermometer or when precise root-zone temperature management is important.
Remote Temperature Probe
The included remote probe allows temperature to be monitored directly around the propagation or rooting area rather than relying on the ambient air temperature surrounding the controller.
For propagation applications, position the probe approximately 25mm into the rooting area to monitor conditions close to developing roots.
Correct probe positioning is important because the temperature of the growing media can differ significantly from the surrounding room temperature.
Simple Setup
- Position the temperature probe in the desired rooting or growing area.
- Keep the thermostat controller safely away from water and wet propagation areas.
- Connect your compatible heat mat or heating device to the thermostat.
- Connect the thermostat to the appropriate power supply.
- Select your desired temperature.
- Allow the controller to automatically regulate the connected heating equipment.
Compatible Heating Equipment
The Cultiv8 Temperature Controller can be used with compatible:
- Propagation heat mats
- Seedling heat mats
- Heat bars
- Heat rods
- Other suitable horticultural heating equipment
Always ensure the total connected electrical load does not exceed the controller's 1000W / 4.3A maximum rating.

Why Choose the Cultiv8 Heat Mat Thermostat?
A propagation heat mat provides warmth, but adding a thermostat provides control.
The Cultiv8 Heat Mat Thermostat automatically regulates connected heating equipment according to the temperature detected at the probe, helping prevent unnecessary continuous heating while maintaining more stable root-zone conditions.
Its combination of a 20–42°C adjustable range, digital display, calibration function, remote probe, and 1000W capacity makes it a practical addition to both small propagation setups and larger indoor growing environments.
