Cold is the silent enemy of indoor growing: it slows growth, encourages stagnant humidity and weakens your plants. The EcoHeat 135W tube heater keeps an even temperature inside a grow tent or greenhouse of around 2.4 m², for active roots and steady development all year round. Selected by BloomLED, a growshop expert for more than 10 years, it sets up in seconds.

The 91.5 cm tubular format spreads progressive warmth along its full length, with no aggressive hot spot. Your plants enjoy a stable temperature, ideal for germination, cloning and steady growth.
By keeping the air above the dew point, the EcoHeat limits condensation, helps prevent mould and protects your crops during cool nights and the shoulder seasons.
Just plug the heater into a 230 V socket: no complex configuration. Placed horizontally or mounted higher up, it fits every growing space thanks to its 135 W perfectly calibrated for 2.4 m².
With no built-in thermostat, it remains fully compatible with an external thermostat to automate day/night cycles and optimise your energy consumption.
The EcoHeat 135W is designed to warm a growing space of around 2.4 m², such as a medium grow tent or a small greenhouse. For a smaller volume, choose the 45W or 80W versions; for a large space, the 240W model will be more suitable.
Do I need a thermostat to use the EcoHeat 135W?No, the heater works immediately once plugged in. To regulate temperature automatically and save energy, we still recommend pairing it with an external thermostat that switches the heater off once the target is reached.
Is a tube heater safe around plants and humidity?Yes. The tubular format heats gently with no flame or fan, making it well suited to the humid environment of a growing space. Simply keep a reasonable distance from foliage and the tent walls.
A controlled temperature means steady growth and yields that reward your effort: the EcoHeat 135W is the year-round ally of indoor gardens.
