When you have a grow room, one thing you must never forget is proper ventilation. Just as we need air to breathe and survive, plants also need enough air to grow and survive. Plants require CO2 from the surrounding air; this CO2 is absorbed by the plants, helping them breathe and promote photosynthesis. Cannabis plants absorb ten times more air than most other plants. They suck up the CO2 from the year within a minute and are in constant need of air circulation. This makes proper ventilation in the grow room necessary. One of the best ways to get good ventilation in your grow room is setting up oscillating fans. Oscillating fan swings back and forth to distribute air around the room; the oscillating motion ensures proper dispersal of the surrounding air, so each plant gets enough air needed for its growth.
Getting the best rotating fan for your grow room is not an easy task, especially when there are many cheap models with a short lifespan. We plan to make your search much easier by providing a review of some of the best oscillating fans for your grow room.
Looking for the best equipment to use in your grow room is really not as hard as it seems. Read the articles below for the best grow tents and grow room equipment.
Reasons You Need a Fan in Your Grow Room
You are probably wondering why a fan in your grow tent is necessary. Plants are living things just like us, and we need similar things to survive. Just like we need water, air, and food, plants need the same. Fans distribute clean air across the room, making sure your grow room is not too hot. Below are some reasons why a fan is very necessary for your grow room.
Proper Airflow and Ventilation
This is an important reason for getting a fan in your grow room. For cannabis plants to grow properly, a light breeze needs to be created. This breeze helps to circulate carbon dioxide (CO2) and oxygen throughout the room. This constant airflow helps to facilitate photosynthesis during the day. Your plants absorb the carbon dioxide passed to them and produce oxygen, which is also needed in the room.
Control Temperature and Humidity Levels
Cannabis needs to be grown at a constant temperature and humidity level. This temperature helps your plants thrive and should not go beyond the maximum limit. Grow lights provide light for your plants, but they also produce a little bit of heat, which alters the temperature and humidity in the room. Cool air circulated by fans is needed to balance the temperature in the room and ensure your plants don’t suffocate.
Reduces Growth of Mold and Bacteria
Grow tent is a very good environment for mold and bacteria to thrive because of the high humidity level and stale air in the tent. To avoid this problem, stale air needs to be constantly removed from the grow room. Most grow rooms or tents have a ventilation window, which helps to freshen the air inside the tent. Fans help to disperse the clean, fresh air displacing the old stale air from the room. The constant flow of this air reduces the humidity inside the tent and limits the chance of mold and bacteria growth.
Strengthens Plant Branches and Root System
Outdoor plants are often moved around by the wind; this helps to build the resilience of such plants as well as strengthen their roots, branches, and leaves. Inside a grow tent, the wind is provided by fans to move the plants around, thus building their strength.
Provide Better Oxygen and Carbon Dioxide levels
Respiration and photosynthesis are one of the processes plants undergo. These two processes are at their peak during the day. During photosynthesis, plants use the carbon dioxide in the room to produce oxygen and glucose, food needed for their growth. This food and oxygen are used up during respiration to provide energy for the plants. For your plants to grow properly, the air needs to be replaced so your plants can produce and absorb more levels of oxygen and CO2.
Types of Grow Room Fans
There are various types of grow room fans, and they each serve different purposes.
- Oscillating Fans
: This type of fan is the cheapest and most popular fan used in grow rooms. Its neck moves back and forth to circulate air throughout the room.
- Intake Fans
: Intake fans suck clean air from outside into the grow room. This fan works together with outtake fans to ensure ventilation.
- Exhaust or Outtake Fan
: Exhaust fans are the opposite of intake fans. They remove the old air from the grow room. They act as vacuums and forcefully pull the old ait out of the room.
- Inline Fans
: This is the best type of ventilation for a grow room. It allows for proper ventilation by simultaneously pushing old air out of the room while letting fresh air outside into the grow room.
Grow Tent Oscillating Fan Buying Guide
A fan in your grow room not only helps to maintain the temperature in the grow room, but it also helps to eliminate odor and maintain fresh air. It is important to purchase a high quality fan that is made with durable materials and lasts long.
One of the qualities of a good oscillating fan is its 90-degree rotation and coverage area. If you’ve purchased an oscillating fan in the past, then you know the qualities to look out for; if you have not, here are some factors you need to look out for before buying one.
Grow tent size
This is a vital factor to put into consideration when looking to buy an oscillating fan. There are different sizes of grow tents available, and you should choose a fan based on this size. You don’t have to get a big fan if you have a big tent; what you need is a powerful fan that can cover a reasonable distance.
Another thing to look out for on the fan is its CFM (Cubic feet per minute). It’s a measure of the volume of airflow per minute in cubic feet. It explains how much air it can circulate in a minute. To determine the CFM your grow room needs, calculate the volume of the grow tent by multiplying its length. Width and height. Compare the volume of your grow tent with the CFM on the fan. This is a better way to figure out the size of the fan that you need.
The material used to build the fan is very important. There are many substandard oscillating fans out there built with low-quality materials; this makes it necessary to know the type of material to purchase. Most fans are built from steel or ABS plastic; these are durable materials that don’t damage easily. Also, make sure the fan is certified by any global marks to ensure its safety.
Installing an oscillating fan is one of the easiest tasks. Oscillating fans should be very easy to install and should not need professional help. There are two installation options for an oscillating fan; wall-mounted or standing.
A standing fan has a stable base that keeps it balanced on the ground. It is good for grow tents with enough space. The disadvantage is that standing fans are not usually firm on the ground; they tip over easily and may damage your plants when they fall.
Most indoor gardeners prefer a wall-mounted fan. It hangs up on the wall of the grow tent and doesn’t take up any floor space. It also provides a wider coverage because it sits above the plants.
Adjustable speed setting
Oscillating fans should have a feature that allows you to adjust the speed of the fan. This gives you control of the way the air is moved around in the grow tent. Most fans have a three-speed setting to represent high, medium, and low speed. It has a knob or buttons that allow you to adjust the speed conveniently.
Angle of oscillation
The oscillating angle explains the maximum area the fan can cover in a single rotation. A good oscillating fan has a 90-degree rotation. You can find few fans that rotate up to 360 degrees. You should avoid fans that need to be adjusted before they can rotate.
Choosing a quiet fan would save you from stress in the future. Some fans make noises when they rotate; this can be frustrating for you. Look out for oscillating fans that operate silently.
