Grow Gadget Tube Heaters

The Grow Gadget Tube Heater is a great way to help maintain a consistent climate in the grow area during difficult cooler months, creating even, radiated warmth for smaller sized grows, reducing the need for concentrated heat sources that can cause burning and safety issues.

How Grow Gadget Tube Heaters Work

To grow successfully, you’ll need to maintain a consistent environment. Commonly grown plants thrive at temperatures of around 25-28 degrees centigrade during the ‘lights on’ period and around 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 tube heater whenever readings drop below optimal levels.

These tube heaters are incredibly economical. Depending on the version, they run from just 60 watts, and radiate enough heat to warm up a small to medium sized space by a few degrees (depending on the external environment). Because it functions more similarly to a radiator than a heater, the end result is a consistent warming of the surrounding air, without a single point of excessive heat to damage plants or cause safety issues. The tube heaters are also splash-resistant, forming a sealed unit, unlike cheaper, and vastly inferior, alternatives which may even pose a safety hazard.

For complete control, the tube heater can be connected to a thermostat, so that, whenever the temperature drops below 18, it will kick into action. This way, consistent temperatures can be maintained with very little hassle.

How To Use

How to Use the Grow Gadget Tube Heater

The tube heater is very simple to set-up and run. All that is required is for the unit to be plugged in and placed in a sensible area away from liquids, ensuring that the outer edges of the heater make no contact with any external materials, such as tent fabric, plastic or plant matter.

One strategy to get the most from your tube 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 Ecoheat tube heaters 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.
