20 Best Fans For Grow Tent (2023 Updated)

I can’t say enough GREAT things about this fan. !!! First of all it comes with 10 speeds and it’s amazingly quiet, i couldn’t believe how quiet my tent got after replacing 2 GrowBuds fans with 2 AC Infinity CloudRay S6 with Auto Oscillation fans! Next, you’re now able to connect them to your existing setup with AC Infinity Exhaust fan, light, and hygrometers and can be individually controlled accept oscillation unless oscillation was on when fan turned off because when you turn it back on it’ll start with the same speed and oscillation as when it was turned off.

Still a nice feature, i love it! My tent got 4° cooler just by swapping fans for AC Infinity fans that are ONLY working on speed “6” out of “10”. I’m using CO2 in my setup so I need the temperature to stay above 80° and below 86° for CO2 to work/photosynthesize properly so, for me the temperature drop wasn’t a good thing, but for most it will be 😊 I just need to turn the fans down a little to allow the heat to build up more because these fans are really doing a great job of moving the air around.

Didn’t expect for the temperature to drop a little, but for me it’ll be very useful for those very hot 🔥 days when they come, so I’ll just need to get adjusted to this awesome power and proper cooling that’s only available with these AC Infinity fans.

I’m sure that for people with much bigger setups than 4’x4′ tent you’ll need bigger fans like the 9″ AC Infinity that’s being produced as we speak but anything beyond that you’ll need bigger fans and that’s a totally different setup because now that’s more of a professional setup and totally different amounts of finished product which is normally not for personal use.

As home setups go, this is by far the Best purchase I have ever made and I have a feeling it’s going to remain the Best for a while because I can’t see how can someone make a better fan then that! Hands down the best 6″ Clip-on Oscillating Fan on the market today.

I’ve tried GrowBuds, GrowBrite, and a couple Chinese (no name) models, but they all suck and don’t come close to the way AC Infinity works! Highly recommend! Outstanding seller, very helpful, very knowledgeable, NOT trying to sell you when you ask for for help or ask questions! Simply, a pleasure doing business with! This is my 3rd fan i bought in 2 weeks.

My family just bought a couple too. I’m telling everyone about them so everyone can upgrade save you should too. I promise you’ll be very happy you did!.

I really like the tent clip style. The app and UIS have given me no problems and make setup convenient and easy to adjust. The down sides make me pretty unsure if this is a small upgrade or a step sideways from other clip fans.

I’m not yet convinced the longevity of this will be significantly better than a cheaper fan. It is constructed externally like nearly every other fan you’ve used (plastic housings, etc. ) I’m hoping the IP-44 rating is what will make the lifespan difference.

The plug location on the fan head makes routing the UIS cable kinda difficult to get a satisfactory result. The oscillation causes wire movement which has me concerned about wire chaffing/fatigue long term.

if your tent bows in at all (like during exhaust negative pressure) the fan will likely contact the tent walls on both sides of the oscillation travel. You can hear the oscillation motor slightly load when this happens and this also makes me wonder about the longevity.

Fingers crossed on the lifespan. All the other AC infinity products have held up so far so this will probably do the same.

I had the privilege of being one of the people to test these fans ahead of time on my YouTube channel. And let me tell you…. I received them in December and I have not had any issues as of yet. They have been going strong 24/7 the past 5 almost 6 months on the #8 setting while oscillating.

They don’t slow down or make strange noises when they oscillate like most of the other cheap fans on the market. These run just like a fan should. They are also fairly quiet and push as much air or more than the little blizzard.

These fans are safe, tested and stamped with safety approval. This might increase cost slightly but at least they won’t burn down your house, not to mention that they last longer than a couple months.

They also have warranty! Just like everything else made by Ac Infinity, these fans are great. We needed new pole fans and ac infinity made it happen. There will even be bigger models available. Thank you to the Ac Infinity Team for putting out gear we all need.

ROG.

This fan is rated for 190cfm and it does that and maybe more. I had one of them for my intake (on a mushroom fruiting chamber) and a cheaper fan that was also rated at 190cfm along with another booster fan rated for 100cfm on my exhaust.

I had to turn the ipower fan down with a speed controller so the other 2 fans could keep up.

We are using this as an exhaust fan on our 37 belt sander and its doing a fantastic job. It can mount horizontal or vertical so we had options on the installation. Its way better than I expected, since most other fans we priced for the same size and cfm were over $700.

Its been run pretty solid for a month now. If it continues to perform at this level, we will add more for other operations in the shop.

Solid construction and this moves a lot of air. The humidity in my basement is very high in the summer. This fan takes the humidity outside through a vent pipe very effectively.

I purchased 1 of these for my 4×4 tent so I could remove the milk crates I had stacked in the corner for my oscillating fan and couldn’t be happier. So much so that I bought another one for my 5×5. I was skeptical at first l, as I thought I wasn’t going to be able to mount it.

ZIP TIES was all I needed to securely mount it to corner pole of my tent. I have it on low and that’s all the breeze I need. Plants look like palm trees in Miami blowing in the wind. The 90 degree oscillation covers my whole tent.

Trust me NO MORE SMALL CLIP ON FANS THAT WONT STAY PUT AND IVE GAINED ALL MY FLOOR SPACE. IF YOU’RE IN A TENT I THINK THIS IS A MUST HAVE PRODUCT.

One of the fans came with box tore. When I opened the fan was broke plastic pieces busted off. The other fan worked about 5 hours then quit working. oscillation still worked but not the turning of the fan blades.

Very disappointed just junk not as described with product pictured. Nothing usable and the one piece that maybe good was bent when crammed in the small box. Went right to the curb for trash pickup in the same box as shipped just wrapped a twenty around it.

Good product with a decent price and “FREE” shipping to Hawaii. A lot of outfits won’t even ship to Hawaii. The cost of the shipping (for the ones that do ship) is so high, it sometimes cost more than the item I want to purchase.

This fan works great. Thank you Walmart!.

Solid and simple design. quality paint ,good power for a 6 inch,dependable. almost the same quality as a canfan 6 inch or a vortex 6 inch. cant go wrong with hurricane or vortex or can fan. there 6 fans are all pretty much the same quality and cfm.

the only difference is probably the quality of the inner parts which I would need more research to give a honest opinion on that topic. hope that helps guys. its a good fan but if you can get 1 of these 3 brands for cheaper pick the cheapest one cause there all pretty good quality.

Moves air nicely! I have this paired with a 4×8″ Phresh filter for my 2x2x5. 5 tent, and it definitely creates a negative air pressure environment in the tent. I’ve only been using it for about a month (installed September 2015), so only time will tell if it lasts.

I keep mine running 24/7.

I’m usually a “lurker NOT a commenter” but with this product I make an exception. I picked up a S6 fan to replace an older cheap duct fan to move air from a room with a wood stove To the hallway in front of the bedrooms a distance of about 30 feet.

The construction of the fan looks to be of EXCELLENT quality, not some cheap plastic junk. It’s almost too good looking to stick in the ceiling. The quality mounting equipment that comes with it is a real plus.

The only fault I found was where the duct attaches to the fan. I found it to measure 5 ¾ inches but that can be fixed with a strip of cardboard on the mounting flange. The motor itself makes almost no noise.

BUT BE ADVISED…. You WILL hear the air movement… Remember, that’s why you bought the fan in the first place. My fan is about 6 feet from the intake register but I have found that a setting between #3 and # 4 ,like others have said, moves plenty of air with very little noise.

At #8 the thing cranks!!! I have no doubt that this fan will solve my air movement issue.

I don’t get it? This thing is supposed to be top of the line. The aesthetics are cool. The technology with the sensor and the meter readout panel features that make it more appealing. The whole design of the fan looks great.

When the fan powered on it was much louder than I expected, even louder than what my iPower vortex 442cfm at same negative pressure. I believe it’s louder because it has to work faster to achieve the same results as my iPower fan.

Then when you crunch the numbers of the electrical current juicing the fan it isn’t exactly what it’s cracked up to be. In fact, two of two fans only operate at 80% the specs on the sticker. The readout on the display panel may say 80%, or 90% of the 402 CFM, but that’s based on.

94 amps. When in actuality the display panel says 80%, or 90% of the actual. 71 amps. The specification sticker on the fan says 70W, actual 58W. Says. 94A, actual. 71A. As a result of the lower current than specified the fan is unable to achieve it’s specified CFM draw.

Due to this malfunction this AC Infinity cannot achieve full negative pressure in a 48″×48″×80″ tent. It seems clear to me that people are so attracted to it for features and aesthetics that it blinds them from looking into it’s functionality.

It’s become apparent to me that in the past 10 years quality control has gone by the wayside 8n the manufacturing liney.

I recently purchased the 4in in-line fan with temp. and humidity sensor along with the 4in ducting. It is by far the best fan system I’ve ever used!! If your looking for performance and innovation with a fantastic price point this is the system for you.

Especially for the budget grower. The ability to control/adjust the grow environment and up to 4 devices with a swipe of a finger gives you complete control of your grow anytime. It has given me the piece of mind that my plants are exactly where they need to be no matter what stage of life they are in.

I was so impressed with this fan I add the charcoal filter to complete my venting system. I highly recommend this fan system wether a novice or a seasoned grower.

Was initially happy with unpacking the unit. Plugged it into the outlet and found out real quick 😳 that the Mars Hydro inline fan is quieter. But it doesn’t have an app capability so I can deal with a little more noise for the trade off.

If this fan were quieter than the Mars Hydro I definitely would have given it 5 stars 🌟.

Kit is great does what is needed. Controller is best used by phone app. Only gripe/challenge to programmers add wifi capabilities not just Bluetooth. That would make it next level. To adjust away from home or in another room.

Obvious to put together, in several configurations. Smart controller is IMPOSSIBLE – 3 of us couldn’t figure out instructions, had to go online to independent videos, still very difficult to figure out options.

shouldn’t be that hard!!.

Our old one (not this model) died. The humidity in the house was at 57%. Our windows and doors were bleeding. This model had double the cfm. In a week and a bit humidity is down to 20% and the fan finally stopped running 24 hours a day.

Our windows and doors aren’t bleeding anymore! Definitely recommend this product. It came with everything we needed for the installation.

Solid steel, well constructed and powerful fan. I installed fan in the basement and ducted it up the bathroom wall to replace my old bathroom fan. It runs so quietly I often have to look at the switch to make sure it is turned on.

The only drawback is that it needs 12″ X 12″ space and my floor joists are only 9″ high, so you need to plan where you want to hang it. Hanger brackets were supplied.

Powerful, could use it in a huge tent if you wanted. I’m using it in a 2×2 tent and it’s much more than enough. High quality, works well. Motor in fan is strong enough that it doesn’t run silently, it makes a mmmmm noise.

Not so loud you have to speak up or turn up the radio, etc, but a noticeable background noise if you are in the same room. Of course if you increase the fan speed you get the sound of moving air–if you turn it way up it really blasts the air.

But at lowest setting you can barely hear the air movement, just the hum of the motor. It was a good value for me.

Very quiet and I like the adjustable speed

I got this to boost a 120v dryer that its blower went out. It worked great for 1. 5 months for that. I did exceed its heat rating slightly. But the 4/5 star doesnt have to do with that. Cfm rating isnt accurate.

But still good flow for grow tent (I’ve grown before) It’s because the casing is very loose. Falls apart. If you use some black electrical tape to tape it up. its perfect and enhances flow. The high heat or vibration also caused the fan blade to come off the shaft.

And bind up and luckily I was at home and heart it to unplug it before it burned. I superglue the fan duct back on and it’s still trucking along. I know this is likely due to the heat. But it still needs a better locking case.

That has nothing to do with heat it’s not properly sized plastic and the locking twist snap is very short. So one little squeeze and it pops apart. Overall it’s a good fan though. Put tape on it and grow away!!!.

Fan LOOKS really nicely made and sturdy. Pretty but it leaks an leaks quite badly at that. This leaks a good amount of air threw the middle seam where it’s put together. You can feel the leak blowing from a distance.

I bought this to vent my cnc laser engraver. Disaster because it just sucked smoke from inside the case an blew it all over the room. Covering this thing in duct tape and now it works but it’s ugly. An to have to modify something straight out the box is never fun.

It’s quiet, works flawlessly and endlessly. It doesn’t work with speed controllers, it will slow marginally and then stop dead and hum/groan so this fan is full speed only. It preforms great at full speed however and I am very happy with this, so much so that this is my second one.

I have 1 on the intake with a modded/hacked house filter and the exhaust one is hooked to a carbon filter. I have another fan I paid more than twice as much for and it slows nicely with a speed controller but it maxes out at 100 CFM so I must say it again.

I am very happy with this fan.

Quality fan! Do yourself a favor and buy this fan the other fans like it don’t even come close to the quality ofthis fan! Thing is solid, very good quality I bet you could throw it off a mountian and the thing would still work lol!.

This thing moves some serious air, no complaints. No vibration or weird humming like some of the cheap in line fans. It is loud without filter or muffler on it, but what fan isn’t. Great buy, great product.

Quality unit and has no issue moving air as promised. It’s noise level is as expected, but can be reduced by adding a length of duct on the inlet.

Its starting to make another weird noise first was the clicking noise now its making another weird noise total of two weird sounds. Feel like that thing its gonna fudge up soon. Regret paying all that money for that fudge up fan.

😒🤦†♀ï¸.

I purchased this inline duct fan to resolve heating/cooling issues in our master bedroom above the garage. I installed the fan on 5” duct work and used 2 feet of insulated noise reducing flexible ducting.

Only place to install the fan was about 3 feet from the take off duct at the furnace, where the fan has to move it about 20 feet to the bedroom register. Atmosphere website has full specs for the product which I used heavily to research my purchase.

The 10 year warranty also moved me to this purchase as well. Solved our heating and cooling issue and moves a lot of air. Very low noise from the unit it self. No vibrations from the unit – I did place neoprene on the mounting bracket as a precaution.

Only noise is a massive increase in air flow to the bedroom. I also installed atmosphere’s varispeed triac switch, since I needed to turn the fan to low-Med because it works too good. Overall I’m very happy with my purchase.

I have used can fan, can fan Max, and a couple of lower-end generic centrifugal fans. This is the quietest centrifugal fan I have ever heard. At full speed it is quiet, unobtrusive. Coupled with a speed controller set to approximately 50% the sound is practically unnoticeable.

The integrated gaskets for connecting to ducting or carbon filters works really well. In all aspects this is an excellent product and performance is top-shelf.

IMO this line of product takes nothing more that the Vortex name. With high hopes after reading all the hype. I ordered several, upon opening the first box, I had a strong feeling that these were no where close to the other Vortex Fans that I’ve used for many many years, some which have been running for decades w/o any issues.

These fans felt like a cheap toy compared to my other Vortex Fans. Clinging to any hope that I might be wrong, I installed three. Within a month they were all three had broken or stopped working and were removed and thrown into the trash.

SAVE YOUR MONEY!.

This fan is simply the 195cfm model. But it is super quiet, and efficient. It will clear the odor 100% of a 2×2 or 3×3 (with carbon filter) within an hour. Or simply exchange all of the air within 5 minutes.

For the price, you can’t beat it. I definitely would recommend this fan for any small grow. A 6″ is not needed unless you’re running a cool tube. And even then you could get a 6″to 4″ adapter and it will do the job just fine.

Fit perfect with existing bolts that were used to hold the original panel. The build quality was excellent with no odor, no flash, no burrs or sharp edges. It was nice because iIdidn’t have a filament printer to make this myself and my Photon was too small.

You can make a 2-piece design of this and then you would have to glue it together. So this was perfect.

Awesome product! Does what is intended to use it for!
