Even with the developments of new mixed flow and hybrid flow technology, inline centrifugal fans are still the preferred choice for growers. You may ask why? It is simply down to centrifugal fans having the ability to handle the airflow resistance generated by hydroponic carbon filters and long duct runs. The Black Orchid Centri-flo™ fan is no exception, it has a generous maximum airflow of up to 250 m3/hour against a staggering 370 Pa resistance. This renders the fan almost ‘stall proof’ as it far outperforms it’s RVK Systemair and Ruck alternatives.
The Black Orchid Centri-flo has built-in temperature control. The built-in temperature and speed control feature allow more control over your environment when you are not around. This protects your plants from the stresses of increased heat by increasing fan speed to full if things get hot and humid. The extractor fan will control the heat in your room by automatically ramping up the speed of the air in relation to temperature. Simply position the external probe in your grow room or tent, set your desired temperature on the fan and adjust the speed to the minimum required setting. The fan will then maintain constant airflow unless the temperature rises. If the temperature rises above the setpoint, the fan will kick into full speed. When the temperature drops, the fan will ramp down to normal speed again.
This fan should be used according to your desired set-up.

Why your grow room needs fans
Your grow room needs fans all year round, no matter what the temperatures are like outside – they are always beneficial. They help with a variety of different problems that might otherwise arise and don’t just work to cool a room down. Ways they can help include:
- To Circulate the Air In Your Grow Room
- To Remove Excess Heat & Hot Spots
- To Control Humidity
- To Prevent Pests and Diseases
- To Control CO2
- To Circulate the Air In Your Grow Room
Outside, plants are going to encounter wind at some point. However, the wind never blows in the same direction for very long, and so you want to avoid having a static fan blowing. Oscillating fans and others that have movement are ideal for creating a more natural air circulation. You can place two fans in opposite corners to create a circulating vacuum of air.
To Remove Excess Heat & Hot Spots
Your grow room can easily get too warm depending on the conditions outside and within the area, you are growing. Grow lights emit heat, and whilst it may not feel like much to you, a slight increase in temperature can really affect your plants.
Some grow lights emit more heat than others but even with lights known to run cooler such as air-cooled lighting and LEDs, it is still wise to have fans blowing. They will help to keep the general temperatures lower and help with air exchange.
To Control Humidity
Another factor that can create problems in a grow room is humidity. Plants release water vapour throughout the day and this increases the humidity. If this level isn’t controlled, the growing conditions will decline.
A good ventilation system will help to wick away some of the water released during transpiration. This allows your plants to absorb more water and pull up nutrients through their root systems, which in effect helps with boosting growth.
To Prevent Pests and Diseases
Good air circulation will help to prevent pests and diseases taking hold. Stagnant and humid conditions are the preferred breeding ground of mould, powdery mildew, spider mites and fungus gnats. And we don’t want any of those to get in!
A steady breeze thanks to a few fans also makes it harder for the pests to establish themselves on the plants.
To Control CO2
Plants need outside air for one very basic reason: CO2. This is absorbed naturally throughout the day as part of a plant’s nutrient cycle. With a sealed grow tent set-up, the level of CO2 will gradually decrease, and this will limit growth.
Ventilation brings in the fresh air and fresh CO2 from outside whilst removing the old air from your grow room.
