Lighthouse Wireless Thermostat for Grow Room Heating

Hold your target temperature without watching the room

The Lighthouse Wireless Thermostat switches a heater or chiller on and off according to your grow room temperature, so equipment runs only when it is needed. It is a two-piece, plug and play kit: a thermostat with an in-built temperature sensor to set and monitor your target, and a plug/socket that sits between your heater and the mains and switches the power supply. Because the halves talk wirelessly, the sensor sits at canopy height while the socket stays at the wall. It has 2 functions - heating or cooling - and a backlit LCD display.

Key Benefits

• Two functions in one unit - control heating or cooling depending on what the room needs.
• Wireless placement - the sensor sits where the plants are, not at the socket.
• In-built sensor - reads and acts on real room temperature, no separate probe.
• Plug and play - hang it, place it or wall-mount it, with no wiring and 2 x AA 1.5 V batteries.

Night-Time Temperature Crashes

The biggest swings happen when nobody is in the room. Lights go off, extraction keeps pulling, and the tent drops below where roots stay active - nutrient uptake tails off and growth stalls overnight. Run the other way, a heater on a plain timer overshoots and pushes humidity out of range. Switching on measured temperature rather than the clock holds the room in a tight band around your set point.

How to Use

• Fit batteries: install 2 x AA 1.5 V batteries in the thermostat unit.
• Plug in the socket: connect it to the mains and plug your heater or chiller into it.
• Select the mode: heating or cooling to suit the connected equipment.
• Set your target: dial in the temperature you want the room held at.
• Position the sensor: place the thermostat at canopy height, away from direct light and the heater's output.
