G.A.S Day & Night Heater Controller

G.A.S Day & Night Heater Controller

A simple dial-based heater controller that lets you set different target temperatures for day and night cycles — essential in UK winter grow rooms where night temperatures can crash without supplemental heat. Plug your existing heater into the controller and it switches on when temperatures drop below your set point, separately for day and night.

Why growers choose the Day & Night Heater Controller:

• Separate day and night temperature targets — slightly cooler at night is normal; full-cold is not, and this prevents both
• Works with any plug-in heater — oil-filled radiator, fan heater, tube heater — controller doesn't care, it just switches mains power
• Prevents winter grow-room failures — UK outdoor temperatures drop below 5°C regularly; unheated grow rooms get in trouble fast
• Simple dial controls — no menus, no firmware, no failure modes that leave you unheated
• Much cheaper than a full environmental controller — does the heater job properly on its own

Who it's not for:

If you want a single controller handling fans, humidifiers, dehumidifiers and heaters together, the G.A.S Enviro Controller V2 is a cleaner solution. You'll need to provide your own heater — this is controller only. For precise temperature targeting (e.g. held to within 0.5°C), go for a digital thermostat rather than this dial-based unit.
