Improve Greenhouse Airflow

Best Fan for Grow Tent – 12 Amazing Products and Reviews

When it comes to growing plants, there are numerous things to think about and cover in order to have good results.

Growing plants indoors is especially tricky and the ventilation system is one of the essential things to have in mind.

Many growers, especially those with less experience, neglect the importance of ventilation and that’s why their results and returns are not as good as they should be.

Given that I have a lot of experience in the gardening field, I will share it with you and present you with some of the best grow tent fans which are supposed to provide precious ventilation to your plants.

As I said, ventilation is very important because it provides much better absorption of nutrients to your plants, helps them to breathe, improves plant growth, and, finally, enhances photosynthesis.

Since ventilation is so important and you need grow room fans to maintain a good level of ventilation, below you can check out a list that I’ve created that contains the best inline fans for grow tents and oscillating grow tent fans that you can find on the market.

1. VIVOSUN 6 Inch Inline Duct Fan


VIVOSUN 6 Inch Inline Duct Fan
  • Weight: 9.3 kg
  • Noise level: 37dB
  • Fan speed: 2550 RPM

Key features

Apart from grow tents, this inline fan can be used in various other places such as kitchens, grow rooms, bathrooms, etc.

Some even consider this fan the best overall inline fan for grow tent.

The installation is quite simple and the fan has a carbon filter that is supposed to eliminate hot air, any unwanted smell, and stale air.

And every grower knows that the awful smell can sometimes be very irritating and problematic.

Additionally, there is an Australian Virgin Charcoal Bed which helps this device to provide an excellent level of ventilation to the plants.

The housing and the composite fan blades are made of plastic, so the noise level is low and you shouldn’t have problems with it, even though some users claimed that it has been louder than it is supposed to be.

Furthermore, some users have heard certain scrapping noise coming from the fan, but again, I haven’t experienced anything similar, so I suppose it’s not a common problem with this VIVOSUN fan.

The filter should be changed every 6 months and this grow tent fan comes with one extra filter so you won’t need to buy it for at least one year.

Finally, this fan has a very good price-quality relationship and I can assure you that it’s a good bargain.

What we like
  • Made of quality materials
  • Easy installation
  • Very affordable
  • 1 extra filter
What we don’t like
  • Possible noise problems
  • Heavy

2. TerraBloom 6 Inch Inline Fan


TerraBloom 6 Inch Inline Fan
  • Fan speed: 2400 RPM
  • Power: 70W
  • Dimensions: 29.2×20.3×20.3 cm
  • Weight: 2.5 kg

Key features

This inline fan for grow tent is made from ABS plastic which is a great material and it has two main benefits.

First of all, the device is not too heavy and it’s, thus, very mobile and easy to carry and relocate.

And second of all, plastic is supposed to reduce noise.

However, if it’s still too noisy, there is a built-in speed controller that can also be used for noise reduction.

Just slow the fan’s motor from 100% to 50% and you’ll notice the significant difference when it comes to noise.

The device is easy to install as well as easy to clean and maintain, and it can be used for grow tents but also for basements, attics, etc.

Finally, the fan can work in temperatures up to 60°C.

As for the cons, most growers complained about the fan’s lack of durability and high level of noise.

What we like
  • Simple installation
  • Easy to maintain and clean
  • Affordable price
What we don’t like
  • Noisy
  • Not durable

3. AC Infinity CLOUDLINE T6


AC Infinity CLOUDLINE T6
  • Noise level: 32dB
  • Weight: 3.26 kg
  • Variable speed controller included

Key features

This grow tent fan can, just like the previous ones, be also used in a kitchen, a grow room, or any other grow space.

AC Infinity CLOUDLINE is made of plastic material so it’s very lightweight and it’s not supposed to make much noise.

As for the above-mentioned controller, it can be used to control numerous things such as temperature and humidity in your tent as well as the speed of the fan.

However, the opinions on the controller are divided.

On one hand, there are users who are thrilled with the controller and assert that it has made their life easier.

On the other hand, some users claim that the controller has had a short life span and that some of its functions simply haven’t worked properly.

To sum up, in my opinion, AC Infinity CLOUDLINE fan deservedly has an excellent mark on Amazon since it’s really powerful, easy to install and use and it’s not expensive, and even though it’s not the best inline fan for grow tent out there, I’m sure most users would be satisfied with it.

What we like
  • Reasonable price
  • High-quality plastic material
  • Low noise level
What we don’t like
  • Possible controller issues
  • Possible short life span

4. iPower 6 Inch 442 CFM


iPower 6 Inch 442 CFM
  • Fan speed: 2380 RPM
  • Power: 95W
  • Noise level: 65dB
  • Weight: 6 kg

Key features

First of all, this device is very impressive with its 95W of power.

There is also a remote control that comes with the fan and which can be used to control its speed.

Additionally, the fan comes with a 1-year warranty and it can work at a temperature of up to 80°C.

The fan is easy to install and it comes in several sizes.

Furthermore, this iPower inline fan for grow tent is not robust, on the contrary, it’s quite small, and that is always a positive feature given that it won’t take up too much space.

However, it’s covered with double ceramic coating which makes it much heavier than some other inline fans.

In addition, this coating increases the noise, so it’s not surprising that this inline fan has a noise level of 65dB.

The coating, of course, also has its positive sides and one of the most important is that the device is durable and doesn’t require any special maintenance.

The price is reasonable so, all in all, the iPower inline fan is a powerful, durable, and reliable, but at the same time heavy and noisy device.

What we like
  • Durable
  • Powerful
  • Reasonable price
  • Easy to set up
What we don’t like
  • Heavy
  • Very loud

5. Comfort Zone 6 Inch Fan


Comfort Zone 6 Inch Fan
  • Corded power source
  • Dimensions: 44.5×45.2×49 cm
  • Weight: 680 grams

Key features

This fan is a bit different than the other previous inline fans on the list since this is an oscillating fan.

Given that it’s less powerful than other fans on the list, it’s much more suitable for bedroom or office ventilation, but it can also be used for plants.

Unlike other exhaust fans, it has a strong clamp underneath which is supposed to provide a firm grip which makes this fan a table fan and clip fan as well.

This feature makes this Comfort Zone fan unique since most oscillating fans do not have a clamp.

The clamp opens easy and the grips are padded with rubber so a surface on which this fan is clipped won’t be damaged.

This way you won’t need to use duct tape or any other means to attach the fan.

This clip fan is among the quietest fans and it has two-speed settings.

Apart from being adjustable in terms of variable speed, the head of this oscillating fan is also adjustable in terms of direction, so you’ll be able to adjust where you want the fan to blow.

When it comes to downsides, many users complained that this clip fan tends to catch on fire and sometimes make some irritating rattling noise, both because of certain problems with the motor and the mechanism.

What we like
  • Cheap
  • Lightweight
  • Fully adjustable head
  • A clamp
What we don’t like
  • Not powerful
  • Sometimes produces weird noise
  • Mechanism problems (fan often overheats and catches on fire)

6. Hurricane Classic Oscillating Fan


Hurricane Classic Oscillating Fan
  • Corded power source
  • Metal fan grill
  • Dimensions: 12.7×50.8×66 cm
  • Steel support neck
  • Weight: 1.36 kg

Key features

Hurricane fan’s construction is made of steel whereas the fan itself is made of plastic.

Hurricane Wall Mount fan is easy to install and has three speed settings (high, medium, and low) and two pull cord controls.

One pull cord is used for adjusting the speed and for turning the circulation fan on or off.

On the other hand, the other pull cord is supposed to adjust oscillation and help you set the perfect air flow.

Hurricane’s tilt is adjustable as well, so you’ll be able to adjust the fan’s position as well as the direction in which it blows.

The only complaint that I would have is the fact that this oscillating fan is not so powerful and, thus, if you have a greater number of plants, you should probably opt for some other fan.

On the other hand, some people who purchased this Hurricane Wall Mount fan claim that the plastic it’s made of is very fragile so it can easily happen that it breaks.

In conclusion, taking this fan’s features and price into consideration, in my opinion, this device is a solid bargain.

What we like
  • Lightweight
  • Simple installation
  • Adjustable speed and oscillation
  • 1-year warranty
  • Reasonable price
What we don’t like
  • Somewhat fragile
  • Not so powerful

7. Vortex S-600 Fan


Vortex S-600 Fan
  • Dimensions: 44.7×28.4×26.9 cm
  • Power: 66W
  • Voltage: 120V
  • Frequency: 60Hz
  • Weight: 3kg

Key features

This is probably the most powerful grow tent fan so far on the list.

It has a strong motor, that is energy-efficient, and double insulated walls.

This insulation helps both with preventing the condensation as well as with silencing the noise that the Vortex fan emits.

There is also a variable speed controller that can certainly make the use of this fan easier.

One of the best things regarding the speed and sound, even if you increase the speed of the fan, the noise it emits won’t be any higher.

However, sometimes that noise can be a bit loud, which is normal concerning the fact that Vortex is a really powerful fan.

Nevertheless, that noise can, for some people, be irritating and, thus, an insurmountable obstacle when it comes to purchasing this particular product.

All in all, the Vortex fan has a good price-quality relationship, the installation process is simple, and the design is very modern, so it can fit into both grow tents as well as grow space inside the house.

What we like
  • Powerful
  • Easy to set up
  • Cool design
  • Fair price
  • Energy-efficient
What we don’t like
  • Sometimes too loud

8. Tjernlund M-6


Tjernlund M-6
  • Voltage: 120V
  • Corded power source
  • Made of metal
  • Power: 125W

Key features

This fan is, just like the previous one, very strong, so it can push air in or pull it out in large quantities and, thus, improve air circulation.

However, since it’s made of metal, it’s a bit louder than some other plastic fans.

But still, that noise is not unbearable and since you get some great ventilation in return, I’m pretty sure that you’ll be able to live with a little noise.

Tjernlund M-6 can be used for indoor grow tents and gardening but also for eliminating moisture or bad smell from the house.

Nevertheless, even though this inline duct fan seems to be almost perfect, there is one thing that I didn’t like at all.

It’s possible to control the speed of the device using a remote control, but it is sold separately.

That basically means that you need to make two purchases to have all the necessary parts to be able to use this inline fan properly.

In my opinion, that is a huge mistake by the manufacturer and I’m sure that many people who think about buying this particular fan, in the end, give up on that purchase because of this inexplicable mistake.

What we like
  • Durable
  • Firm construction made of high-quality materials
  • Powerful
  • Fair price
What we don’t like
  • The speed controller is not included

9. Hydrofarm ACDF6


Hydrofarm ACDF6
  • Frequency: 60Hz
  • Voltage: 120V
  • Noise level: 72dB
  • Weight: 4.5 kg
  • Power: 115W
  • Dimensions: 31.7×31.7×23.6 cm
  • Fan speed: 2890 RPM

Key features

This particular fan provides a proper airflow and will certainly supply your plants with an excellent amount of fresh air.

In addition, it’s very firm and sturdy.

It’s made of metal, so it’s relatively heavy, but it’s also easy to install and maintain.

Given that it produces a great air movement and it’s made of metal, it’s only logical to think that it’s noisy.

And, unfortunately, it is.

However, there are a couple of ways to reduce the noise.

Firstly, you could hang the device by bungee cords and, thus, eliminate the vibrations or simply use the speed controller and set it to lower speed so that the noise level would be lower.

Many people, actually, buy inline fans that are more powerful than necessary, just to be able to lower the speed and, therefore, reduce the noise.

But, all in all, this fan is, honestly, quite loud.

Nevertheless, this fan is, in spite of the noise, a very good option regarding both the quality and the price, and, in my opinion, it should definitely be put on a shortlist.

What we like
  • Sturdy and durable
  • Improves air circulating
  • Reasonable price
What we don’t like
  • Loud

10. Hurricane 20 Inch


Hurricane 20 Inch
  • Corded power source
  • Fan speed: 1400 RPM
  • Metal construction
  • Dimensions: 59x29x63.2 cm
  • Weight: 7.82 kg

Key features

This particular Hurricane Wall Mount fan is probably the strongest and the best oscillating fan on this list.

Its motor is very powerful and makes enough air circulation so your plants will never lack fresh air.

Furthermore, the construction is made of metal so this fan is quite heavy, but also very sturdy and firm, and almost unbreakable.

Unlike other oscillating fans on the list which had plastic blades, this Hurricane Wall Mount fan has very sharp metal blades that can work in 3-speed levels.

Therefore, keep in mind that it’s very dangerous to close your hands to the fan blade or let children play around it.

Both the oscillation and the tilt can be adjusted.

The oscillation range is 90° and the tilt is not as adjustable as with some other oscillating fans, but it’s still on a satisfactory level.

Although this compact fan seems to be almost perfect, several users complained that it has a short life span and I have to admit that it’s quite expensive, especially for an oscillating fan.

I haven’t used it long enough to determine whether it’s true or not, but all of you who consider buying this oscillating fan should keep in mind that a short life span is a possible downside.

But again, regardless of this issue, from my perspective this Hurricane Wall Mount fan is the best oscillating fan on the market.

What we like
  • Powerful motor
  • Sturdy and durable construction
  • 3 speed levels
What we don’t like
  • Short life span
  • Pricey

11.  Comfort Zone Oscillating Circulation Fan


Comfort Zone Oscillating Circulation Fan
  • Corded power source
  • 3 speed modes
  • Weight: 2.6 kg

Key features

This circulation fan has an AC motor and 3 blades and it can cover a maximum of almost 5 meters when it’s set on the highest speed mode.

Even though it has metal blades, it’s pretty quiet and the oscillation is adjustable (80°).

Apart from the oscillation and speed, the tilt is adjustable as well.

Additionally, although it’s not large and heavy, the Comfort Zone Air Circulation fan can move a solid amount of air.

In terms of design, this exhaust fan is more suitable for bedrooms or kitchens, but it can also be used for grow tents.

One of the main cons of this fan is the fact that, apart from the blades and the fan cage, the entire construction is made of plastic and, thus, it’s a bit fragile.

However, if you take good care of it and try not to drop it or kick it around, it should last long enough.

The price is very reasonable and, in my opinion, this fan has an excellent price-quality relationship.

So, if you need a somewhat powerful and quiet fan and you don’t want to spend much money on it, the Comfort Zone Air Circulation fan is a great option.

What we like
  • Affordable
  • Lightweight
  • Quiet
  • 1-year warranty
What we don’t like
  • A bit fragile

12. VIVOSUN 4 Inch Inline Duct Fan


VIVOSUN 4 Inch Inline Duct Fan
  • Fan speed: 2930 RPM
  • Weight: 750 grams
  • Power: 12W
  • Voltage: 110/120V

Key features

This is probably the simplest fan on the list.

It’s made of metal, apart from blades which are made of plastic, and that is always a safer option.

Furthermore, even though it’s not large and heavy it can provide a satisfactory amount of fresh air to the plants.

Thus, it’s recommended for smaller or medium grow tents.

When it comes to temperature, the motor’s maximum operating temperature is 130°C, while the maximum ambient temperature is 60°C.

Regarding its size and weight, this fan is quite powerful and doesn’t require any special maintenance.

As for its downsides, it doesn’t have any speed settings or controllers.

It can be, simply, turned on or off and that’s it.

Therefore, VIVOSUN 4 Inch Inline Duct fan is probably the best fan for some old-fashioned gardeners who don’t have time and will to bother with some technologically advanced inline fans.

What we like
  • Easy to install and simple to use
  • Lightweight and portable
  • Cheap
What we don’t like
  • No controller
  • No speed modes

FAQ


Is it good to leave my fan on in a grow tent?

Well, the unwritten rule is to leave the fan on during the light hours of the day. Namely, during this period the heat and the humidity can have some a bad effect on your plants and, thus, the ventilation is necessary so you need to leave the fan on.

During the night hours, a fan can be turned off.

How do I know what size extractor fan I need?

In general, any fan that you can afford is okay and it will certainly help your plants. However, there is a rule which is used to determine what size of the fan is necessary for a certain room.

That rule says that you need at least 1 CFM (cubic feet per minute) of air per square foot of the room.

So, just do simple math and determine the square footage of your grow tent or grow room and you will know exactly what size extractor fan you need.

Do I need a carbon filter for my grow tent?

It’s not mandatory but all the best fans have carbon filters. Namely, carbon filters eliminate the smell from your grow tent and keep it out of it.

That means that your plants will be able to breathe the freshest air possible and that will certainly help them grow better, bigger, and stronger.

Conclusion

My goal was to present you all the features, as well as the pros and cons of the best oscillating and inline, grow tent fans in this text, and I hope I managed to fulfill that goal.

As for my opinion, for me, the best fan on this list is Vortex 347 CFM S Line S-600 fan because it has excellent quality as well as an affordable price, so I think it’s a great bargain.

However, all the other inline and oscillating fans are also great options and I’m sure that all gardeners who have grow tents will find the convenient fan that meets all their criteria and conditions.
