Each of the several broad categories of fans is designed for a particular use. Therefore, you should define your needs before trying to choose a fan for your grow room.

Unlike inline fans, oscillating fans turn back and forth, slowly changing the direction of airflow in a growing room. This helps to move cool air around.

The choice of the best rotating fans isn’t easy. You will most probably come across cheaply made models that have a very short lifespan.

Our main objective today is to help you choose a design that will be almost ideal for your growing environment.

What to look for the best Oscillating Fan

There is no reliable grading system for fan efficiency when trying to choose the best model. However, we have uncovered a few tips that will help with your selection.

Cubic Feet per Minute (CFM)

This refers to the airflow rate, which is the volume of air the fan delivers in a given time. Visualize one cubic foot as a block of air measuring one foot by one foot by one foot.

Almost all manufacturers supply a cubic foot per minute rating, showing the volume of air the fan will push per minute.

A larger number indicates more air movement in your growing environment. However, small differences don’t interfere with airspeed.

CFM can also be used to determine the efficiency of the fan. Theoretically, CFM divided by watts gives an efficiency index.

The higher the index, the more efficient the fan is in using energy. Other manufacturers may argue that the efficiency index is of little importance.

You should also know that oscillating fans that deliver the highest air movement tend to be noisy. But this is normally wind noise and nothing to worry about.

Size

Oscillating fan size may range from as small as 6 inches to more than 20 inches. The size is usually determined by how large the blades are by design.

Most ideal size for a grow room should range from ten to twenty inches. Blades of such sizes can drive sufficient air in the grow room.

We recommend a 16-inch, 18-inch, or 20-inch for most normal size indoor gardens. However, you can opt for a larger rotating fan, if your growing space is larger.

It is also worth mentioning that the blade size determines how big the fan is, but the number of blades is no indication of its quality or performance.

According to our analysis, a three-bladed model can move more air than a five-bladed model, depending on the size and pitch of the props.

Speed Settings

It is advisable to choose a fan with variable speed settings. This helps to effectively control how the air is moved in your growing environment.

The most popular models are equipped with three speed settings: low, medium, and high. You can adjust the speed conveniently.

Variable speed controls help to eliminate any stagnant air in the room, thus improving the transpiration rate of your plants.

Apart from the front mounted control knob, you can opt for a model that comes with a pull chain control for easy adjustment.

Tilting and Adjustable Head

The convenience of controlling the oscillation is of utmost importance. An ordinary oscillating fan will just rotate from left to right, but an advanced design allows you to modify the oscillation.

Consider a unit that has a tilting head (can move up and down). This enables you to mount the fan facing downwards or upwards conveniently, depending on where you want the air to be directed.

Some models are engineered to oscillate in a unique figure eight motion. This kind of oscillation maximizes air movement in the grows room in all directions.

You can also opt for a model that can be locked into a specific position. This will conveniently allow you to direct air to one specific direction at a given time.

Mounting Options

This may as well be one of the most important factors when shopping for a quality oscillating fan for grow room.

There are two major types of mounting or installation options you can consider: standing and wall mounted.

A standing rotating fan is ideal for a grow room with sufficient flow space to spare. However, a standing model can tip over and damage the head or even your plants.

Also, most standing designs are not very sturdy. Repeated contact with the fan may deteriorate the structural integrity of the stand.

The most desirable option for most growing rooms is a wall mounted oscillating fan. You will not have to worry about floor space.

Wall mounted units are also very sturdy. They sit above the plants’ canopy, providing a wider coverage.

Remote Control

Apart from the control knob and pull chain control, you can choose a model with remote control. This allows you to change mode and speed easily without having to use the knob.

Some manufacturers, such as Hurricane, engineer remotes that can be used universally to control more than one fan in the same growing space.

Safety Features

We recommend you to choose oscillating fans that are ETL listed and CETL approved. Such models come with safer parts that will not expose you to any danger during use.

Final Words

The aforementioned products are our top five oscillating fans for growing rooms. However, you can choose a separate model that’s more appealing to you.

When shopping for a high performing model, consider a fan that has a head that can oscillate as well as tilt upwards and downwards.

The size of the blades depends on the amount of air movement you need in the grow space. A 16-inch, 18-inch, or 20-inch size is sufficient for most grow rooms.

Consider a model with variable speed settings, three to be precise. This will help to effectively eliminate stagnant air and enhance transpiration rates of your plants.

For easy and convenient operation, we recommend a model that comes with remote control.
