Lighthouse 2KW Grow Room Heater – 1000W/2000W Thermostat

Thermostatic fan heat that moves warm air around the whole grow room

The Lighthouse 2KW Grow Room Heater is a fan heater that blows warm air around a tent or grow room, holding air and root-zone temperatures where plants want them on cold nights. It has a thermostat, 1000W and 2000W heating modes and a fan-only setting, so it holds a set temperature instead of overshooting and stressing the crop. A compact 23cm x 19cm x 32cm body, weighing 3.8kg, tucks into a corner.

Key Benefits

• Two heating modes (1000W / 2000W) match output to the size of the space and the season, with a fan-only setting to move air without adding heat.
• Thermostatic control senses room temperature and cycles the heater to hold it steady rather than swinging hot and cold.
• Fan-driven heat moves warm air through the room so plants furthest from the unit stay warm too.
• Splash-resistant - rated IPX4 for a humid grow space.
• Ready to run, supplied complete with a power lead.

Is a cold grow room stunting growth overnight?

A space that drops too low overnight slows metabolism and root activity, and a cold root zone is a common cause of sluggish growth and weak roots even when light and feed are dialled in. Cold, damp air also sits in the canopy and pushes humidity up, adding mould risk. Heating the whole room evenly keeps temperatures consistent everywhere, not just in front of the unit.

How to Use

• Stand on a flat, stable, non-flammable surface, clear of plants, drip lines and tent fabric.
• Plug in with the supplied lead and set the thermostat to your target, typically the low-to-mid 20s Celsius depending on stage.
• Choose 1000W for smaller tents or mild nights, 2000W for larger or colder rooms, or fan-only to circulate air.
• For large rooms, add a second unit rather than running one heater flat out.
