The Grow Gadgets Temperature Controller keeps your grow room temperature to within 1°C. Set your target temperature, plug in your heater or cooler, and let the controller do the rest. It handles up to 3,500W, so it will comfortably run a 2.5kW heater, and a temperature probe is included in the box.
Why Choose the Grow Gadgets Temperature Controller?
- Controls heaters and coolers: Use it to hold a cold tent, shed or greenhouse up to temperature, or to run a cooler when the room gets too warm.
- 3,500W max power load: Plenty of headroom for a 2.5kW heater, and well above what a heat mat or small fan heater pulls.
- 9°C to 50°C range: Covers everything from a cool propagation space to a warm flowering room.
- Accurate to 1°C: Tight, steady control through every stage of growth.
- Memory function: Your settings are kept after a power interruption, so you are not resetting it every time the power blips.
- Probe included: Everything you need to get going is in the box.

Who Is This For?
Anyone running a heater or cooler without proper temperature control. It suits grow tents and grow rooms that get cold in winter, sheds and greenhouses, and propagation setups where steady warmth makes a real difference to germination and early growth. Check the wattage on your heater or cooler before you plug it in and keep it under 3,500W.
What To Pair It With
- Heaters: The Ultra Flat Grow Room Heater, the Lighthouse 3kW Heater, the Lighthouse 2kW Greenhouse Heater and the Lighthouse Oil Filled Radiator all sit under the 3,500W limit.
- Propagation: The Grow Gadgets Propagation Heat Mat is a low wattage load that is well within the controller's limit.
- Other options: Prefer a different style? Have a look at the ITC308 Temperature Controller from Inkbird or the Lighthouse Wireless Thermostat.
