Extractor fans are indispensable elements for indoor growing. In order to have an excellent climate control, humidity and temperature, it is needed to implement extraction systems that renew the air inside the grow room and prevent the plants from being affected by a stale environment.
Having an optimal extraction system will provide the grow room with optimal air circulation, which is essential for the plants to undergo a smooth photosynthesis process, as air renewal is essential for the plants to convert inorganic matter to organic matter.
The grower is often in doubt as to which type of extraction system is most suitable for its purposes. The extractor fan for air renewal it is very easy to use, it has an internal motor to extract the stale air from inside the grow room through a suction system, in a very similar way to the extraction ducts of a room, for example.
To select the best extractor fan to suit your growing conditions, you need to know the cubic metres of your growing space. To do this, it is simply necessary to multiply the width, height and depth of the cabinet and you will have to give a final result that is expressed in cubic metres.
Once you have a measurement in cubic metres of the growing space, you need to do another simple calculation, which is to multiply by 60. The reason for this is to calculate the required flow rate based on one hour, and one hour is made up of 60 minutes. Once you get this result, you will have a figure that will be the minimum desirable flow rate for the extractor.
Types of extraction fans
There are two main groups of extractor fans for indoor growing. Firstly, helical extractors are those that have the blades positioned around the motor shaft and promote the expulsion of large quantities of air. This type of extractor is not the one that works best with anti-odour filters, although for a small room it is very convenient due to its low cost.
On the other hand, there are also radial extractors, those with better features for the grower. At Experiencia Natural there is an excellent selection of extractors of this type, which work by generating air suction from the stale air that is expelled from the grow room through the exhaust duct. This type of extraction system is powerful and quiet.
The RVK Sileo extractor is one of the best options on the market for all types of growers. It is one of the best value for money options in our catalogue.
One of the best options for those growers who do not want to spend a lot of time with calculations and measurements is the purchase of a complete extraction kit. This type of pack includes an RVK type extractor, an anti-odour filter and an extraction tube. Everything is ready to plug and play.
The extraction system inside a grow room is a very important part that should not be neglected. Maintaining correct humidity, temperature and ventilation values is closely dependent on the use of quality extractors, which take stale air out of the grow room and allow clean air in for the plants.
Last but no least, the extraction system is not one of the growing aspects that is not worth saving money on, as it is dependent on many elements that work in harmony to control the overall conditions in the grow room.
