Tips For Growers to Choose the Right Grow Fan
If you are building your grow room or thinking about it, you might have heard about grow light, grow fan and ventilation systems for a grow room.
Beginners might get confused about the use of a grow fan or multiple fans inside a grow room, and they might be skeptical whether they should install fans or not. Therefore, we are here to discuss this topic in detail.
Why Do You Need Grow Fans?
Grow fans are essential for a grow room because of various reasons.
Grow Fans For Ventilation
The apparent or first reason for installing grow fans is ventilation. Fans circulate the air and replace the inside air with fresh air.
Ventilation is not only necessary for workers in the grow room, but it is also essential for the growth of indoor plants and their yield.
Plants take carbon dioxide from the air present in the grow room. Due to the consumption of carbon dioxide, its concentration decreases with time, and in the end, there is no carbon dioxide left for photosynthesis.
If the concentration of carbon dioxide is low, then plants cannot produce their food, and it will affect the yield. In severe cases, plants may die.
Thus, it is necessary to intake fresh air and expel the present air from the room. It ensures the optimal concentration of carbon dioxide to carry out photosynthesis and improve the yield. With the help of grow fans, a fresh supply of carbon dioxide is always available.
Grow Fans For Temperature Control
The second reason for installing fans is temperature control.
Due to grow lights, the temperature inside the grow room increases with time. These lights produce heat that accumulates in the air; consequently, the temperature is increased.
Different types of grow lights are available, such as LED grow lights, CFL, incandescent lights, and HID. All these types of light emit heat which increases the temperature. However, LED lights are very efficient, and they emit minimal heat compared to other types.
Fans also help in reducing the temperature of the grow room. They expel out the air and take fresh air inside the room. This ventilation process maintains a suitable temperature inside the grow area.
Grow Fans For Humidity Control
Humidity control is quite essential when it comes to indoor grow rooms. If it is not controlled, it can lead to various problems.
The best way to control humidity is using fans. The exhaust fans expel the humid air, and the intake fans take fresh air. It maintains the humidity level of the area.
Odor Control Also Needs Grow Fans
Indoor grow fans also play an important role in odor control.
Most of the plants in the indoor grow room produce an odor, and the intensity depends on the type of the plant.
The exhaust fan expels the odor out of the room, but it can irritate your neighbors. If the odor goes out of your house or garage, it can annoy people passing by the area and your neighbors. Thus, a grow fan and filter are used to expel the air and eliminate its odor.
Different Grow Fan Types You Should Know
Based on function, grow fans can be divided into three categories.
1.Exhaust Fans
The most crucial type of grow room fans is exhaust fans, also called extractor fans. This type of fan is necessary for all grow setups, whether you have a large grow room or small tent. If you have a small grow area, you can use a small grow room exhaust fan or grow tent extractor fan.
2.Intake Fans
Intake fans are responsible for replacing the expelled air with fresh air. These fans also play an important role in the ventilation system of a grow room, but they are not necessary.
3. Oscillating Fans
Oscillating fans are the simplest of all. These fans are only for circulating the air in the grow room. If your grow room is large, these fans are necessary.
Tips to Choose the Right Grow Fan for Your Grow Room/Tent
1) Decide the Type of Fans You Need
According to the size of your grow room, you need to decide which type of fans you need. We have already discussed that an exhaust fan is necessary for any type of grow area, whether it is a grow room or tent.
The other two types of fans are used if there is any need.
For instance, if you rely on a passive intake system, there is no need for a grow tent intake fan. You can need a few intakes holes that are larger than the exhaust holes. However, it is better to have an active intake system to improve the performance of your grow room.
Oscillating fans are for large grow rooms and tents. If you have a large grow area, you can use these fans to create a breeze inside the grow room.
You need to decide which type of fans you need. For tents, you can buy a grow tent fan setup. You can easily find a complete setup in online stores.
2) Size of the Fan
The size of the fan is the most complicated decision that you need to make. It needs some mathematical calculations.
It is crucial to select the right size of the fan according to the size of your grow room/tent.
3) Get a More Powerful Fan
We have already told you that you need a more powerful fan than the requirement. It is because when you use a fan at its 100%, its life derates with time, and it produces too much noise.
Thus, it is better to use the fan at 25% lower than its capacity and allow it to work well.
Keep in mind that some companies already add it in the multiplying factor, so you don’t need to increase the fan rating in that case. You can discuss it with the company.
4) Use a Grow Fan Silencer
Fans produce noise; you cannot expect them to be very quiet. They can even disturb your neighbors. Therefore, you need to mitigate the noise of fans.
You can use a fan silencer with the indoor grow fan to mitigate the noise. It is attached to the end of the fan and mitigates the noise to a great extent. It is recommended to use the fan and silencer of the same brand or company.
5) Grow Fan and Filter
The combination of a grow fan and filter is vital to remove the odor from the indoor room. The fan expels the smelly air, but it cannot remove the smell.
Therefore, a filter is installed to eliminate it. Thus, the air coming out of the indoor room does not have a smell. If you want to keep your indoor room hidden or private, you need to use a filter.
