CLIMATE CONTROLLER

GSE Digital Temperature and Depression Controller: total command of your grow room climate

In indoor growing, the quality of your harvest depends directly on a stable climate. The GSE digital controller drives your extraction and intake fans at the same time to keep a constant temperature and a controlled negative pressure inside your grow tent. The result is continuous, draught-free air renewal that preserves the ideal humidity and reduces the risk of mould and heat stress on your plants. Whether you are running a compact tent or a full grow room, this single unit centralises your climate management and replaces several separate timers and speed regulators, giving you reliable, repeatable conditions through every stage of the cycle.

🌡️ Independent extraction / intake control

The two outputs manage the extraction and intake fans separately, perfectly balancing air renewal and negative pressure without creating draughts that could harm your plants.

🌿 Climate precision and stability

With ±0.5°C and ±4.5 % RH accuracy, the GSE controller maintains a homogeneous atmosphere, essential for steady growth and flowering.

💧 Long-range digital probe

The 4 m cabled sensor, extendable up to 50 m, can be placed at canopy level or in critical zones for readings that reflect what your plants actually experience.

🛡️ Built for humid environments

IP44 (10 A) or IP54 (16 A) sealed housing and protected sockets: the controller withstands the humidity typical of indoor cultivation.

⚙️ Hysteresis and fine tuning

Adjustable hysteresis, depression from 50 to 100 % and fan speed from 20 to 100 %: limit unnecessary start cycles and extend the lifespan of your fans.

Which version should I choose, 10 A or 16 A?

The 10 A version (IP44) suits most spaces with a standard extraction fan. Choose the 16 A version (IP54) if you drive powerful fans or demanding equipment: it accepts up to 2300 W per output and offers superior sealing.

What is negative pressure and why set it?

Depression is a slight under-pressure inside the room: extraction draws out a little more air than the intake brings in. Adjustable from 50 to 100 %, it prevents odour leaks and ensures all air passes through your carbon filter.

Does the controller also manage heating or a humidifier?

Yes, the outputs accept up to 2200–2300 W and are compatible with fans, humidifier and heating, letting you centralise the climate management of your space.

Can the probe be placed away from the unit?

Yes. The digital probe ships with 4 m of cable and can be extended up to 50 m, ideal for large rooms or to measure temperature directly at plant level.

One single device for temperature, humidity, depression and fan speed: the GSE controller simplifies climate management and protects your harvests, from early growth right through to the end of flowering. Backed by BloomLED expertise and expert advice, it becomes the dependable climate brain at the heart of a well-tuned indoor setup.
