When it comes to indoor growing, airflow and air circulation is one of the most forgotten elements of an indoor growing space. Trust me; you will be putting your plants at greater risk for environmental related problems and stunted growth. Ventilation is essential for your plants to thrive in your grow tent. The environment of your grow tent is not an aspect you want to overlook, a good fan will ensure your plants have good ventilation, temperature, humidity and airflow. When it comes to indoor farming, having the best fans for your grow tent is paramount.

Why do I need ventilation?

The grow tent fan provides perfect ventilation for your grow room or tent, keeping your plants healthy.

Proper ventilation helps remove carbon dioxide-depleted air, creates good airflow throughout all plants and keeps humidity levels steady.

They are also the best solution for keeping your grow space at the right temperature to avoid burning your plants. Lights generate heat, which can burn your plants if not dissipated properly. Fans make indoor growing easier and more efficient with all the air circulation and exhaust system benefits.

However, even if you are not concerned about the heat in your grow tent or room, you still need to change the fresh air every 1–3 minutes.

A decent breeze helps strengthen the stems. Frequent air renewal helps prevent problems like mold, rot, mites, and mildew by evenly distributing water vapor and heat.

Grow Tent Fan Buying Guide

If you’re not entirely sure which type of fan you need and which features are important, this buying guide will clarify some things. We’ll start with a brief introduction to the different types of fans.

Different types of fans
There are 3 basic types of fans commonly used in horticultural applications:

Inline fan
Oscillating fan
static fan

Each type of fan serves a specific purpose. Most serious growers will need all 3 types to operate successfully.

In addition to humidity control and temperature control through a central A/C unit or window sills or portable units, air circulation is necessary for the reasons discussed earlier.

Just controlling temperature and humidity is not enough. Each type of fan will help you in a different way.

Inline fan
These fans are usually installed in ductwork or used as exhaust fans blowing air directly outside. They don’t always come with sensors or on/off switches, but many higher-end models do.

They are called inlines because they are used with ducts as an integral part of the ventilation system rather than a stand-alone fan that blows air around the room.

A true grow tent will require at least 2 inline fans, one for intake and one for exhaust. Some larger operations will have several inline fans to do the job. Smaller tents usually only have one exhaust fan.

Shaking fan
Oscillators are fans used to move air around a tent or room. Where embedded fans are used in closed systems to draw air from the outside or push air from the inside to the outside, an oscillating fan keeps the air inside from becoming stale.

They also play an important role in stirring the plants, acting as an artificial wind within the closed system. Plants need natural forces to move around to help them stay healthy, and since there is no wind indoors, oscillating fans are replacing natural wind.

This type of fan is also good for maintaining temperature over a large area. Hot spots can develop quickly in any room, especially one with grow lights and other heat sources.

The area near the light can be a few degrees warmer than the rest of the tent. Moving air from one place to another will make the ambient temperature in your space more even. The moving air is also used to dry the plants and prevent mold from forming.

Static fan
These are the basic fans you’ll find everywhere. They do not oscillate or move. They can sit on the floor or be clipped to a structure, but static fans are stationary.

Static fans are used when you need to constantly move air in a specific area of the room and you want the airflow to stay in the same place over time.

A good example of when you need a static fan is if you have an area with several lights in one place. A static fan cools the surface temperature of the light and cools nearby areas before an oscillating fan moves the air out of the area.

Fan size
The bigger the fan, the more air it can move. It’s a simple concept that makes choosing your fan size easy.

Of course, this isn’t always the only problem, considering many of us work with limited space constraints. If you have a huge warehouse, you just buy as many max fans as possible and move as much air as possible.

Queue
Inline fans come in a variety of sizes. The most common sizes you’ll see in grow tents are 4" and 6" with occasional 8 or 12" fans. They do get bigger, but once you get past 8 inches, you’re getting into some heavy-duty big spaces, not a normal grow tent situation.

Vibrating
Oscillating fans also come in a variety of sizes, but most will require a 12-inch fan or larger, which is the most common size. If you have a regular grow tent, chances are you’re looking for a small oscillating fan for grow tents that measures around 12 inches. These move a lot of air and don’t take up much space.

Stationary
Static fans can be found in the same size as oscillating fans. The most common in our applications are clips on 8" or standard pedestal fans. Most box fans that sit on the floor are about 20 inches. You can choose the size you need according to your specific situation.

Budget
Because followers are so important, it makes sense to spend the money you have on the best fans. Since they’re usually not that expensive, you can get better fans for just a few bucks more in most cases.

You want a fan that lasts a long time and moves a lot of air. You also generally want it to do so with minimal noise.

There are a lot of poorly made fans that you can get for very cheap, so be careful! If you stick with the fans we’ve highlighted here, you’re sure to get a quality device at a reasonable price.

Conclusion

Grow tent fans are important equipment for indoor planting. Installing these fans is simple using the instructions that come with each fan. With all the options above, you can easily choose the best fan for your gardening area to keep your plants healthy and happy.
