Keep Growroom Conditions Optimal During Colder Periods

The Lighthouse 2KW Greenhouse Heater is a great way to help maintain constant temperatures during the difficult cooler months, creating even, radiated warmth for larger sized rooms and areas. While the heater helps greatly in the cooler months, it also doubles as an air circulator: you can set it to a 'no heat' option and just use the fan. There's also a 'half power' mode that heats the room at 1kw. It also features a controllable thermostat to keep your room temperature optimal at all times. Please note that when the heater switches off, the fan stays on.

How this Heater Works

To grow successfully, you’re going to need to maintain a consistent environment. Plants thrive at temperatures of around 25-28 degrees centigrade during the ‘lights on’ period and at 18 degrees in darkness. As winter approaches, maintaining these temperatures can become difficult without some form of supplementary heating, especially during hours when lighting is switched off. For this reason, we recommend the use of a heater whenever readings drop below optimal levels.

The greenhouse heater runs at a wattage of either 25w for fan only, 1000w for half heating power and 2000w for full heating and will heat a area of 20m2 with ease, with an air output of 186m2 per hour.

How to Use Lighthouse 2KW Greenhouse Heaters

Place the unit in a sensible area away from liquids, ensuring that the heater doesn't come into contact with any external materials such as tent fabric, plastics or plant matter.

One strategy to get the most from your greenhouse heater during colder months is to schedule the heater to switch on as the lights turn off, at the beginning of the dark cycle. As heat from lighting equipment dissipates, the Lighthouse Greenhouse Heater will provide enough warmth to maintain temperatures in the correct range for small grows during dark hours. This will, of course, be dependent on the surroundings.


When using the greenhouse heater for the first time you may notice a slight emission of smoke, this is quite normal and it stops after a short time the smoke is caused by the left oil when heating. To avoid overheating do not cover the heater.
