1220mm Greenhouse Heater – Low Consumption Tubular Heating for Indoor Growing

The 1220mm Greenhouse Heater is the silent guardian your indoor crop needs to survive and thrive during the coldest months of the year. It is a tubular heating device designed specifically to provide a constant, gentle, and radiant background heat that raises the ambient temperature without drying out the air or consuming the electricity of a conventional radiator. It is the definitive tool to keep the climate stable when the lights go out.

Is the cold slowing down your harvest?

We've all been there: you have a spectacular crop, but when winter arrives or the nights get chilly, the temperature in your grow room plummets as soon as the lights turn off. You wake up to find your plants with purple stems, slowed metabolism, and leaves that don't look happy. You try to fix it, but you're constantly worried about the electricity bill skyrocketing or, worse, the dreaded powdery mildew appearing due to condensation spikes.

Living with that uncertainty is exhausting. Seeing how your plants stop fattening up because they are too busy fighting the cold is frustrating. Plus, high humidity combined with low temperatures is the perfect breeding ground for fungi that can ruin months of work in a few days. You feel like you're fighting a losing battle against the thermometer, and standard fan heaters are too aggressive, drying out the environment and creating hot spots that burn the leaves.

The 1220mm Greenhouse Heater changes the game completely. By installing this tube, you generate a thermal curtain that maintains the minimum temperature exactly where your plants need it. It's not about blasting hot air; it's about maintaining a comfortable base that prevents stress and keeps the sap flowing. Suddenly, the dark cycle is no longer a threat, but a period of rest and maturation, just as it should be.

What exactly does this heater deliver?

This device is designed to be effective, safe, and discreet. It is a plug-and-play solution that adapts to almost any growing space thanks to its slim profile.

• 1220mm Heating Tube: The perfect length to cover the width of standard 1.20m or larger grow tents, ensuring even distribution.
• Mounting Brackets: Includes legs or brackets so you can fix it to the floor or wall, preventing it from rolling or touching the fabric of the tent.
• Safety Cable: Ready to plug into any standard outlet or timer.
• Splash Resistance: Designed to withstand the humid environment typical of Climate Control in horticulture (IP55 usually, though always check the manual).

How your routine changes from now on

From the first night you plug it in, you'll notice the difference. You'll stop obsessively checking the thermometer every hour. The temperature graph will stabilize, avoiding those jagged peaks and valleys that stress the plants so much. This stability translates into a faster growth rate and denser flowering.

Also, say goodbye to waking up and finding the walls of the tent dripping with water. By keeping the temperature slightly higher than the dew point, this heater drastically reduces condensation. Your routine becomes much more relaxed: you just check that everything is working, and you dedicate yourself to enjoying the cultivation, knowing that the environment is under control.

Advantages and benefits you'll notice from day one

• Minimal Consumption: Unlike oil radiators or fan heaters, this tube consumes very little (similar to a light bulb), so your bill won't suffer.
• Space Saving: Its slim design allows you to place it in corners or on the floor without taking up space for your pots.
• Fungal Prevention: By reducing relative humidity through heat, it acts as a preventative against botrytis and mildew.
• No Light Stress: It does not emit any light, respecting the dark photoperiod of your genetics 100%.
• Scalability: Perfect for large Grow tents; if you have a huge room, you can place several strategically.

Tips to combine it with other Pevgrow products

To get the most out of your heater, it is vital that you don't use it blindly. The key to success is automation and measurement. If you connect it to a controller, you ensure it only turns on when strictly necessary.

• Thermostats: Connect the heater to a digital thermostat so it turns off when it reaches the desired temperature (e.g., 18-20°C).
• Thermo-Hygrometers: Essential for monitoring the max and min peaks. You can find them in our section of Humidity controller and meters.
• Fans: Place a small fan near the heater (without pointing directly at it) to help distribute the warm air throughout the room.

Frequently Asked Questions

Does it get hot enough to burn the plants?

The tube gets hot to the touch, but it doesn't reach the extreme temperatures of a filament heater. However, you should always maintain a safety distance of a few centimeters between the tube and the leaves or the plastic of the tent to avoid accidents.

Can I leave it on 24 hours a day?

Yes, it is designed for continuous operation. However, for efficiency and to give the plants a natural cycle, we recommend using it with a thermostat that activates it only when the temperature drops below your set limit.

Is it suitable for a 60x60cm tent?

At 1220mm (1.22 meters), this model is too long for a small 60x60 tent. It is ideal for tents of 1.20m x 1.20m or larger. For smaller spaces, look for the shorter versions available in our catalog.

Does it dry out the environment too much?

No. Unlike fan heaters that blow dry air, this tubular heater emits radiant heat, which is much gentler on ambient humidity, helping to keep it in the optimal range without drying out the substrate excessively.

Personal Experience of Pevgrow’s CEO (Alan)

I remember perfectly my first crops in a garage during winter. No matter how much I insulated the room, when the sodium lights went out, the cold was brutal. I tried oil radiators, but they tripped the fuses and consumed a fortune. When I discovered these tubular heaters, everything changed. I usually place a couple of them on the floor, along the sides of the tent. The heat rises naturally through the canopy, keeping the roots warm and the air moving. It's the cheapest and most effective investment I've made to save winter harvests; since then, I never lack one in my setup.
