Brandon Forder Apr 24, 2024 8:10 AM
One of the most ignored features of cannabis growth in an indoor environment is air circulation.
Air circulation is essential for a good indoor cannabis garden since it allows for the interchange of fresh air while also regulating the temperature. Buying the best grow tent fan is essential if you want to take control of the climate in your grow tents.
The best grow tent fans for sale have been tested and reviewed in-depth in the sections below. Inline or clip-on, the options outlined below are worth your attention.

Oscillating Tower/Pedestal/Floor Fans
Oscillating fans, on the other hand, may move air in a sweeping arc across a considerably broader area, and they can usually be modified to move it higher or lower. Your cannabis plants will benefit from increased overall airflow thanks to the oscillation of the casing that holds the blades (often a three-blade design), which moves in a smooth arc motion and allows for more efficient cooling of space than your stationary fans.
Clip-on Fan
With the rise in popularity of indoor grow tents, it's more important than ever to have a fan that can keep up with the demands of your plants. Since clip-on fans circulate air while preserving temperature and humidity, they meet this criterion because they are space-saving and often inexpensive. Similarly to oscillating fans, some clip-on fans can also move in a clockwise or counter-clockwise direction.
Wall Mounted Fan
The ideal option for larger grow operations is a wall-mounted fan. Even while it may not be ideal for small places, it can provide enough power to quickly cool down your grow area. You should use wall-mounted fans in a large grow room or commercial-style grow area if you want significant ventilation. An enclosed grow tent may not be a good fit for certain attachments.
Power
You'll need to know how many cubic feet per minute (CFM) your grow tent is moving in order to properly ventilate or circulate the air within.
"Cubic feet per minute" is the abbreviation for CFM. Cannabis growers use CFM because it represents the volume of air that must be circulated or exchanged every minute.
A few equations must be solved in order to obtain the appropriate CFM rating for inline fans that pull in new air and exhaust hot air.
The length, width, and height of your grow tent should be taken into consideration.
Once you've completed the following steps, you'll be able to meet your minimum CFM requirements. Inline fans, on the other hand, are frequently used in conjunction with ducting, carbon filters, and other growing equipment that requires a higher CFM.
Calculating the appropriate CFM coverage is a simple matter of multiplying your base CFM by 3. You should have at least 210 CFM in a 4x4 grow tent to ensure enough air exchange.
Fan Size
The more air it moves, the bigger the fan has to be. This is a straightforward concept that makes it simple to select the appropriate size of fan.
Of course, this isn't the only thing on our minds, especially for those of us who have limited workspace. In order to move as much air as possible in a large warehouse, you would need to buy as many of the largest fans as you could afford.
Inline
A variety of inline fans are available. The most typical fan sizes in grow tents are 4′′ and 6′′, with an 8′′ or 12′′ fan appearing on occasion. Even while they can get bigger, once you pass the 8-inch mark, you're no longer in the realm of the typical grow tent.
Oscillating
Oscillating fans exist in a variety of sizes, although the most frequent sizes are 12" and larger. If you have a typical grow tent, you'll likely be looking for a small oscillating fan around 12 inches in diameter for use in your grow room. A lot of air may be moved in a small space with these devices.
Static
Oscillating fans come in a variety of sizes, and static fans are no different. The clip-on 8-inch or standard-size floor fans are the most frequent for our use. A typical 20-inch box fan sits on the floor. Depending on the circumstances, you can select the appropriate size.
Budget
It makes sense to spend as much money as possible on the greatest fans you can afford. For only a few dollars more, you can acquire a much better fan than the one you're now using.
For a long-lasting fan that can move a lot of air, look no further than this. You also want it to be as quiet as possible while doing so.
If you're looking for an inexpensive fan, be aware of the dangers. If you stay with the fans we've listed, you'll get a good one at a good price.
Speed Settings
Control over your growing environment is a positive thing. There are two options here: either buy a fan with variable speed settings or buy them separately (as is common practice with the majority of inline fans). Allowing for experimentation, you can adjust airflow, humidity and temperature settings.
When placing your fan, keep in mind how easy it will be to operate the dial and controls. It's possible to manage oscillating fan types from outside your grow room with a remote.
Head Adjustment And Movement Of Clip-on Fans
Controlling the oscillation of your fan is essential to ensuring that your growing space is adequately covered. The more power you have, the better off you'll be. Most fans oscillate from left to right, however some more modern ones feature more complex figure 8 motions for better air circulation.
In addition, the head of your fan should be able to be tilted and adjusted so that your plants' stems get a decent exercise every day.
Safety Features
Your plants require a steady growing environment, which is provided by your grow tent. However, it must also be safe for your plants and those who share your home.
An ETL- and CETL-approved fan is an option. As a result, it has a more secure design and a better build quality.
What is a Grow Tent Fan?
When it comes to grow tent fans, the most common shape is circular, but they can also be square, rectangle, or oblong in design. They are used to produce and improve airflow within the grow tent.
Typically, they include three or more blades inside a metal or plastic cage. At varying amounts of power, most use an electrical source to generate recycled air.
Grow tent fans come in a wide range of sizes and styles, and can either be freestanding or fixed. They can also be oscillating or non-oscillating, floor or table-mounted and even clip-on (monkey fan).
Are Grow Tent Fans Necessary?
It is essential to have grow tent fans to keep the plants in optimal growing conditions, and they are usually used in conjunction with inline fan systems, grow tent heat, and dehumidifiers.
If you want the healthiest and highest-yielding crop, you'll need to keep the temperature and humidity in your grow room in check with these devices.
The plants' stems will be strengthened and your grow tent's air circulation will be improved as a result of the fan's steady light breeze.
What Kind Of Duct Do You Need?
Your inline fans will likely necessitate the installation of ductwork as well.
With an inline fan system, flexible aluminum ducting is a wonderful option for use. It's simple to set up and cost-effective.
If you have a larger tent, you may want to consider using aluminum or a heavier-duty conduit.
Recall that shorter ducts with fewer bends reduce airflow as much as longer ducts with more bends.
How Do You Manage Fan Noise?
Noise is to be expected when using a high-powered fan to air your grow tent. There are, however, techniques to lessen the impact of your growth and make it less obvious.
You'll be able to lessen the noise level by using a fan with variable speed and a CFM rating that's 25% more than what you require.
The majority of inline fan models tested have noise-reducing features. The sound of your intake fan can also be reduced by attaching a suppressor, but this must be factored into your CFM calculations.
At the very least, you'll need an oscillating fan if you're growing weed in a grow tent. An inline fan will likely be required as well in order to exhaust the tent's air. Another inline fan will be needed for larger tents to help circulate the air.
All of the above-mentioned fans will do an excellent job for you. Unless you're working with an infinite budget, we recommend sticking with our top picks because they offer the best value. Then go for the "highest quality" selections.
Do not buy "budget" models unless you have a very limited budget. If you're willing to pay a little more, you can obtain better fans.
