The Grow Gadgets Thermostat Controller gives you precise temperature management by automatically switching connected heating or cooling equipment on and off as needed. With a wide temperature range from -9°C to 50°C and up to 6000 W load capacity, it’s designed to handle heaters, fans, heat mats and coolers safely and effectively. The included detachable probe continually monitors the environment, helping you create a climate that supports vigorous growth, stable flowering and strong overall plant performance.

Whether you’re protecting seedlings from stress, reducing temperature shocks, or preventing heat stress in flower, this controller makes climate management easy and consistent.

Key Features & Benefits

• Automatic Heating & Cooling Control: Switches devices on/off to maintain your set temperature automatically, no manual adjustments needed.
• Wide Temperature Range: Works from -9°C to 50°C, giving you flexibility to set precise climates for different growth stages.
• High Power Load Capacity: Supports up to 6000 W, making it compatible with a broad range of heaters, fans and cooling systems.
• Accurate & Responsive Control: ±1°C accuracy and a digital probe ensure the environment stays as close to your target temperature as possible.
• Memory Function: Remembers your settings after a power outage so your temperature programme continues without resetting.
• Easy-to-Use Display: Simple digital interface makes setting your target temperature quick and intuitive.

How to Use

• Plug the Controller: Insert the thermostat controller into a standard 220 to 240 V mains socket.
• Connect Equipment: Plug your heater, fan or cooling device into the thermostat’s outlet.
• Position the Probe: Place the temperature probe in the area you want to monitor (e.g., central grow canopy or greenhouse mid-height).
• Set Your Target: Use the digital buttons to adjust your desired temperature. The controller will then automatically activate connected devices to maintain that range.
• Monitor & Adjust: For best results, pair with a hygrometer or environmental controller to monitor humidity and airflow along with temperature.

Tip: Use the thermostat with your heating and cooling equipment in tandem to keep conditions stable across both day and night cycles, especially valuable for propagators, seedlings and sensitive crops.
