One of the most overlooked aspects of growing cannabis is maintaining a healthy flow of air. Many experienced growers will tell you that ideally, you want new air into your growing area every one to two minutes. That means you have to keep things circulating!
There are ways that don’t require money — for instance, opening a window every now and then — but considering most people grow in tents, that won’t cut it. The best way to keep air circulating is with a fan. In our grow tent fan reviews, we’ll go over our favorite fans on the market and tell you why we are such fans of each. Let’s take a look!
|Best Overall||HURRICANE 736520 Fan||
|Best Value||Comfort Zone Clip-On-Fan||
|Premium Choice||AC Infinity CLOUDLINE Inline Duct Fan||
|VIVOSUN Inline Duct Ventilation Fan||
|Tjernlund M-6 Inline Duct Booster Fan||
We think that this product is ideal for a small grow tent, which is why it is our top pick. When it comes to changing the air in and out of your grow operation, you don’t need something blowing with gusto. While this product isn’t made specifically for growing, if you just need something to keep things moving, this fan is wonderful for that. It is small, so it fits easily in your growing area, and if you are growing a large amount of product, you can buy several of these fans and they won’t get in the way or cost you a fortune.
This model has a versatile mounting system, so you won’t have to fuss too much with where you put it in your tent. There is also a clamp, so you could just clamp it onto the container that your plants are in. Combined with the right ventilation system, this is a perfect anecdote for a stale air.
Not only is this fan small and flexible, but it is also quiet, which is crucial for your peace of mind. Those who use this for growing operations love it. Now, we wouldn’t recommend this fan for cooling off on a hot summer day, but it is great for making sure that your hard work doesn’t wind up with bugs or mold.
All in all, we think this is the best fan for grow tents this year.
This fan was meant to cool off humans during the hot summer months, and while it is not great for that, it sure is good for circulating air in your grow operation.
This comes as a two-pack, which is ideal for tent setup. You can have one fan situated by the plants you are growing and another to help push the air through the exhaust. This fan is made for the long haul, as Comfort Zone says it will last you for years. The clip-on mounting makes it easy for you to find the right spot to put it in your tent or room.
This fan comes with two speeds, depending on how hot your growing process gets. Both speeds, we are happy to report, are nice and quiet. While many people are more open about their growing operation these days, you still might not want a noisy fan blowing your cover.
Once you have your fan clipped in and set up to blow where you’d like, you can adjust the head. No need to fuss with moving the fan around!
We really love the value of this fan. Because it comes in a two-pack, you could buy several of these at an awesome price and have a decently sized grow operation well ventilated. The only drawback to these fans is that they have, on very rare occasions, caught on fire. That would certainly put a damper on your growth. Because that is so rare, however, and because the value is so good, we consider these to be the best fans for growing tents for the money.
This is a different product from our first two: AC Infinity has made a fan that is designed specifically for growing tents. It’s not only good for keeping the air moving, but it is also great for temperature control, which is a crucial part of the growing process. You can do that with a remote control that lets you adjust the temperature inside your grow tent. With this feature, you can be less hands-on with your growing experience, freeing you up to admire your work.
Not only can you set the temperature on this fan, but you can also set the temperature for different times or turn it on and off, as this model is fully programmable. This fan comes with a timer, an alarm, and fully adjustable fan speed.
You can use this fan with your filter as well, because the duct measurements are the same as most filters and vent sockets in tents. This comes with the ducting necessary to handle the hardware in your tent.
This fan is incredibly quiet, which leads us to our one complaint about this fan: It has little power. While you can hook it up to a filter, you might find that it just doesn’t quite have the juice to work properly with it. We therefore recommend this fan for small grow tents.
This is another quiet fan (30db) that works well to help regulate the flow of air in your grow tent. With a standard size of 4 inches, you can use this with your exhaust filter and expect good results.
This is probably the most powerful fan on our list so far, with a fan that blows up to 2,930 RPMs. That produces an airflow of 195 CFM.
Installing this fan is easy, as both ends are made to be simply inserted into their proper area. Then, all you have to do is wrap them with a layer or two of duct tape. Once installed, you’ll be happy with how quiet this product is.
Specifically designed for growing tents, this fan doesn’t take up much space. Because of that, you can use several of these in one tent if you’d like. While it is great for ventilation, it can also work well for circulation.
This is a good fan even when you aren’t growing! Let’s say that you are in between grows. You can use this as a dehumidifier in the hot summer months, and it is also good for hotter rooms, like basements or kitchens.
This fan has durability issues, which is why it is a bit lower on our list. However, the folks at VIVOSUN are attentive and quick to get you back on the right path toward an ideal growing situation. The reputation that VIVOSUN has cultivated for customer service is second to none.
This mounted exhaust fan is the first of its kind on this list. This is not a fan that runs on its own, but instead, must be hooked up to the ventilation system in your tent. In fact, this fan has many options, but you will have to buy outside accessories for them to work. For instance, you can regulate the speed of this fan, but only with a separate speed controlling device.
This does, however, come with everything you need to mount it to your setup or outside of it. As it’s best used for exhaust and not intake, you’ll probably find yourself mounting this outside of your grow tent.
We think that this fan is good for overall circulation but still should be used in tandem with smaller items, like the first two fans on our list. The amount of power it takes to keep this going is small, as is the noise output.
Most who use this find it to be a worthwhile product, but expect to need maintenance on it in about a year’s time. Considering that it only has a 60-day warranty, that’s not great.
This is a nice tiny fan that can keep the air moving between multiple plants at once. With two different speeds, you can choose how much circulation you need and whether to keep this fan stationary or oscillating. The head itself can be moved forward or back, so along with being able to move the mount itself, this gives you almost 360 degrees of movement.
This is another fan that was made to keep you cool during the summer, so it has multiple applications, but it is not a powerful product, and we would argue that it is much better as a fan for a grow tent than a fan for a human.
The problem with this little fan is the same as with many others: durability. If you leave this motor running, which you need to do in a grow operation, it will burn out quickly. While we think this is a nice product, there are better ones out there for your money.
This is meant to be used with other products, and while the cost on the fan itself isn’t prohibitive, once you put the whole package together, it gets quite pricey. Along with the fan, you need a filter, a speed control unit, and ducting. But when everything is put together, this is a nice product.
It’s a bit more powerful than the other fans on this list. Meant to be used as an exhaust fan, it’s good for circulation and odor control. Of course, the installation of this item is more difficult compared to the little desk fans we’ve reviewed, but this is still a great item for growing.
The problem with this fan is the noise. Even though it isn’t super loud, it is still noticeable enough to be hard to ignore. You can fix this by purchasing the speed control unit, but even then, it is still much louder than anything else on this list.
A grow setup is much like a sports team. You can have all the best items, but if they don’t work well together, then you won’t get very far. For fans for growing tents, this couldn’t be more true. Our top pick is a tiny desk fan, not a fancy high-quality model made specifically for growing. When it comes to getting a fan, know what you need and stick to that. In this section, we’ll go over a few things to consider before buying a grow tent fan.
How much noise can you handle? Of course, there are a couple reasons that you want a quiet fan. The first is that you probably don’t want a loud humming going on in your house all the time. The other is that while growing cannabis is growing more common, many folks still like to maintain a level of discretion.
Depending on the size of your grow operation or the number of plants you have, you will either need one tiny fan, a whole bunch of tiny fans, or exhaust fans. The size of your operation will dictate how much you need to spend on it. If you have a ton of plants, you might want to spend more on a fan that will keep the whole tent temperature controlled and ventilated, but if you just have one plant, there’s no need for anything more than a tiny desk fan looking down on it.
We always advise looking into warranties, even if it is a product with a low price tag. It’s also good to look into the reputation of the customer service team that you might have to deal with. Some companies offer refunds; others care more about their customers and are more prompt in helping.
This is not a complete list of all the fans that exist out there on the market, but it is a wonderful place to start, especially if you are new to the game of growing. You can see that you don’t need something super high tech! So, what were you a big fan of? Was it the multi-use top pick from Hurricane? Or were you totally enamored with the premium pick from AC Infinity? It’s hard to pass up the opportunity to grow something via a remote control! Whatever you choose, we hope that it is a delightful journey for you, from seed to harvest.
