How To Hang Oscillating Fan In Grow Tent

How To Hang Oscillating Fan In Grow Tent

You want your oscillating fans to be able to reach all regions of the growing space, which may entail purchasing a number of fans, but you also don’t want them to be able to point directly at your plants.

Can you hang an oscillating fan upside down?

It was not intended to be hung that way, and I believe the weight of the fan, if it were to be hung upside down, would interfere with its operation. Despite the fact that this is an excellent fan that is simple to install and performs well, I use it in a two-car garage and it truly helps to circulate the air about; it has made a noticeable impact.

How many Wall fans do I need for a grow room?

The finest inline fans for grow rooms have the ability to either push or pull air into the space. Two fans will be required in order to accommodate both.

Do you need fresh air in a sealed grow room?

Closed-loop systems entail the use of a grow chamber that is totally sealed. There is no air removed from or pulled into the grow-space from outside the enclosed grow-space. Instead, a heater and an air-conditioning unit work together to keep the temperature in the proper range at all times. The usage of dehumidifiers and humidifiers can help to regulate the humidity in a room.

Can you have too much airflow in grow tent?

Having an excessive amount of CFM flow in your tent is not necessarily an issue, unless you don’t have enough passive intake ports and the tent walls are bending in, in which case the fan will be put under undue stress. In such situation, you may also use active input fans to aid in the system’s overall balance.

Should I run my carbon filter 24 7?

During veg stage, you should run the inline fan continuously, but if you want to extend the life of your carbon filter, you shouldn’t have it connected at all during flower stage. Only when the buds begin to give off their aroma should it be connected during flower stage if you need it to mask the smell. During the growing process, mine are unhooked until I need to filter the smell.

Do I need to vent my grow tent outside?

It is not required to exhaust the air that is drawn through the carbon filter outside of your growing area; in fact, depending on your configuration, it may even be preferable to have the filtered air returned to the growing area immediately.

Can I vent grow tent into same room?

You may run ducting from the exhaust on your grow tent and direct the exhaust towards a different room or outside your home if you choose. Alternatively, you may just vent it into the same room in which the tent was placed. The second alternative is, without a doubt, the more straightforward. It also eliminates the most significant drawback of venting outside your home: the presence of a noticeable heat signature.

What happens if grow room is too hot?

A poorly ventilated grow room can cause a variety of other issues with your plants in addition to overheating. In the first place, increased water transpiration at high temperatures can lead to nutritional decomposition. Terpenes can also be lost from your plants if they are overheated, resulting in the loss of the distinctive flavors and fragrances from your strains.

How do I bring my grow room temperature down?

Use additives to help protect your plants from the effects of high temperatures! Kelp Extract (from seaweed). Supplement with silica. Supplement for Root Health (Essential for Hydroponic Growing in Heat) Increase the amount of CO2 in the atmosphere.

Learn how to include CO2 into your growing environment. Maintain the coolness of the roots. Reduce the amount of electricity you use by strategically placing fans. Reduce the temperature. Reduce the amount of power you use.

Is 32 degrees too hot for Grow Tent?

Moderator. Anything beyond 30 degrees Celsius/86 degrees Fahrenheit should be avoided at all costs. Because of the high temperatures, the plants become stretched and their buds become smaller and more airy. There are some strains that will fare better in hot temperatures than others.

Do I need air intake in my Grow Tent?

Larger grow tents can also benefit from passive air intake, but they will necessitate the use of exhaust fans with greater CFM ratings. The intake of fresh air is simply one component of the indoor growth equation. Many parameters, including as the size of the grow tent, the number of grow lights, and the number of inline fans, influence the creation of the best growth environment.

Can you install a power supply upside down?

Providing you have adequate space between the intake and the floor (and your case is equipped with a bottom-mounted air-intake grill for a PSU fan to pull air), the answer is simple: you should position your PSU so that it faces downwards. Having said that, if you choose to place your power supply facing up, that is entirely OK as well.

What size fan for 5×5 grow tent?

The best inline exhaust fan for a 55 grow tent is 6 inches in diameter and has a capacity of around 400 CFM.

How do you circulate air in a grow tent?

Here’s what you need to do (it’s simple): Install your grow tent, complete with a grow light inside. Install the exhaust fan at the very top of your tent, so that it is blowing air out of the tent. Make certain that there is an intake opening for fresh air to enter. Install a window fan that blows air out of the room where the tent is located.

How can I hide my grow tent in my room?

When using the sog method, it may be difficult to conceal the tent itself, but how difficult is it to conceal a tiny handfull of little plants, provided they are not at the blooming stage? Simply pull down the tent and store the plants in your closet, concealing them beneath boxes and/or clothes to keep them out of sight.

Do grow tents keep the smell in?

The basic answer to this question is no, grow tents do not have the ability to block off odors. It is possible that the grow tent will have to cover the aroma of your flowering plants before the space can be considered smell-proof. Proper air circulation will assist you in keeping the temperature and odor levels in your grow environment stable and consistent.

What size fan for 3×3 grow tent?

Member who is well-known. 6 inches is far too big for a 33. Every 2 minutes, you should take a deep breath and exhale. Calculate your cubic feet and divide the result by two to get the exact cubic feet per minute you want to be running at.

Is 85 too hot for a grow room?

It is recommended that plants grow in grow rooms between the temperatures of 68 degrees and 82 degrees Fahrenheit, depending on their stage of development. However, if you keep your plants at 85 degrees Fahrenheit for an extended period of time, they will begin to experience a variety of problems.

Can you leave your grow tent open?

Yes, theoretically, you are allowed to keep it open. It is my goal to be able to control as many factors as possible, and growing under a tent allows me to do this. You’re exposing your plants to everything that’s in the room when you do this.

Upgrading My Marijuana Grow Tents with Wall Mount Fans

When growing marijuana indoors in a grow tent, ventilation and air movement are critical components of the growing process. The flowing air simulates the wind and aids in the development of stronger branches, which are more suited for supporting hefty nugs. Airflow was provided by a couple of 6′′ clip fans and a domestic tower fan in my last grow tent, which I found to be sufficient.

Unfortunately, that was not nearly enough. My humidity level rose to an unacceptably high level during my last days of blooming, and I developed a moderate case of bud rot, often known as botrytus.

Hanging Wall Mount Fans in my Grow Tent

A professional grower advised me to “make your plants dance in the wind,” which I did after consulting with him. He recommended the Hydro-farm wall mount fan with metal blades, but I decided for the plastic blade version, which was half the price and worked just as well. The term comes from the fact that wall mount fans are often screwed into the wall. When it came to installing a wall-mount fan in a grow tent, there were some unique obstacles to contend with.


I utilized a piece of pegboard that I had cut into smaller parts to use as a backing for the fan I was making. I hung the pegboard with the help of rope ratchets and a couple of zip ties. The wall mount fan is attached to the pegboard with the help of some stainless steel hardware that I purchased from Home Depot earlier. While I centered the fan on the rear wall of my 55 grow tent, in my 44 grow tent, I was concerned about canopy infringement and wanted to squish the fan into a corner to avoid blocking the light.

Despite the fact that it was more difficult to cut, this form creates a natural balance in the corner and I anticipated it would be easier to attach.

Other Options to Consider

I’ve observed a couple other individuals in their grow tents who are employing wall-mounted fans. A piece of wood stretched over the side wall of his grow tent, with the fan installed atop the board, as described by user TerpKing over on the 420magazine message boards. He screwed the wooden board to the tent poles by drilling two holes on each end and fastening it with zip ties to the tent poles. He’s utilizing ratcheting rope hangers to hang the entire system and to modify the height of the assembly as needed.

How to Hang Exhaust Fan in Grow Tent? The Ultimate Step By Step Guide

Who doesn’t appreciate the beauty of nature? I believe that everyone desires the freshness of the plants that surround them. As a result, gardening is growing increasingly popular on a daily basis. Plants, on the other hand, have their own set of requirements. Their need for a moderate wind and an inversion of the atmosphere, which may be difficult to achieve when cultivated inside, is understandable. So, what exactly are we looking for? What is the best way to hang an exhaust fan in a grow tent?

After that, connect the carbon filter to the exhaust fan and check that the fan is in the proper location.

Growing plants in grow tents necessitates the use of ventilation in this situation.

However, in order to keep the grow tent and the plants within in good condition, you must meet the needs of the plants.

You must ensure that your plants receive excellent quality airflow in order for them to grow properly. To guarantee optimum ventilation within your grow room or tent, understanding how to hang an exhaust fan in a growing tent is an important thing to take into consideration.

How To Hang Exhaust Fan In Grow Tent? Step By Step Guide

The Best Way to Hang an Exhaust Fan in a Grow Tent Step-by-Step Instructions The extraction system for a grow tent is comprised of three basic steps: preparing the carbon filter, hanging the exhaust fan in the grow tent, and installing the ducting system in the grow tent.

Step 1 – Prepare The Carbon Filter

To begin, you must prepare the carbon filter by wetting it with water. In order to prepare for this, you must first uncover the item by removing the protective plastic coating. More information may be found at: How To Make A Carbon Air Filter For Your Grow Tent.

Step 2 – Get The Screws Back

There will be a few screws that hold the flange plate in place on the interior. You’ll have to remove those screws, lift the flange plate up, then reinstall the screws while keeping the plate in an upside-down position.

Step 3 – Cover The Plate

The dust cover should now be placed on top of the plate to protect it.

Step 4 – Connect The Carbon Filter With The Exhaust Fan

Tie The Exhaust Fan To The Carbon Filter In The Fourth Step The following phase is widely regarded as the most difficult, and many individuals find it challenging as well. However, it is not as difficult as it appears, however caution is advised. Connecting the carbon filter to the exhaust fan is the final stage in this process. Activated carbon is used in the carbon filter to absorb and remove pollutants, toxins, and contaminations from water and wastewater. It completely eliminates all of the humidity and foul odors while also purifying the air.

They can be installed in a variety of configurations, such as outside the tent with a carbon filter, inside with an exhaust fan, or both inside and outside with an exhaust fan.

The benefits of having both of them within your grow tent will be greater if you can manage to do so.

Step 5 – Insert One Blade Into The Paper

Make use of your scissors to cut a single blade of one of them into the foil paper at the end of your ducting and then extend out the ducts once more around the perimeter.

Step 6 – Use Shearing MachineWire Cutter

Because the ducting pieces are moving in a spiral motion, it is impossible to separate them. As a result, the cut may come close to meeting the opposite side but will not be able to be separated. The shearing machine and wire cutter are required to separate them at the point where the foil is cut in order to do this.

Step 6 – Continue!

Now take the jack chain and cut it into two equal parts so that you may hang the filter and the exhaust fan with ducting from it. Two portions will adhere to the ends of the duct on opposite sides. As previously noted, two different ducts will be utilized to link both the exhaust fan and the carbon filter, with two duct clips on either end of each duct.

Step 7 – Hung Together

Carbon filter and exhaust fan will be strung together outside the tent using a hanging rail before being linked in place.

Slide one end of the tiny duct onto the flange plate, attach the duct clip, and tighten the screws with a screwdriver to ensure that it is secure.

Step 8 – Placement of the Exhaust Fan

Following that, an arrow will be painted on the surface of the exhaust fan to indicate the direction of airflow. Please make sure that this arrow points in the opposite direction of the carbon filter since the exhaust fan will suck the air that is coming from the carbon filter rather than blowing it through the filter. As a result, when installing the filter and exhaust fan in the grow tent, it is critical to pay attention to the direction of the fan and filter.

Step 9 – Final Check!

Slide the duct over the flange all the way around on the small end of the ducting and secure it with another duct clip at the other end. Then, with the last duct clip, tighten the ducting by sliding the long end over the other end of the ducting. It is recommended that this extraction system be positioned as high as possible in order for the air to move through it correctly. That is why it is advisable to build a grow tent ceiling rather than a floor. In order to hang the exhaust fan and filter outside the tent, you must raise them while they are suspended by the jack chain from the tent frame.

Because it will be more comfortable for you and you will not require any assistance, it is advised that you elevate them while they are not linked.

Support the exhaust fan with the straps attached to the filter and jack chain, and connect them to the hanging rail with the hanging rail connector.

I hope you were able to find the answer to the question “How to hang exhaust fan in grow tent?”

What Are The Effects of The Ventilation System On Plants?

The Influence of the Ventilation System on Plant Growth “How to hang exhaust fan in grow tent” is now something you know. But have you ever considered it? What are the ramifications of having that exhaust fan running? The fact that you are growing plants indoors means you must give them with the best environment possible in comparison to what they would receive if they were growing outside. Plants require a carbon dioxide-rich environment in order to develop properly. Plants can come in contact with an acceptable quantity of CO2 from the atmosphere while they are growing in the open air.

Plant development can be hindered in a variety of ways if this is not the case.

The exhaust fan installed in a grow tent allows us to give them with fresh air, but not too much or too little, which allows them to develop more quickly while also maintaining the humidity and temperature within the grow tent.

Although learning how to hang exhaust fan in grow tent is a difficult configuration to master since it necessitates the use of several methods and tips, as well as certain strategies, it is not difficult if you grasp the procedure completely.

The health of the plant will be improved as a result of this approach. It will aid with the removal of foul odors and excessive heat from within the grow tent, as well as the maintenance of the temperature essential for plant growth.

What Are The Benefits of Installing Exhaust Fan In Grow Tent?

“How to hang exhaust fan in grow tent” is now something you know. But have you ever considered it? What are the advantages of having an exhaust fan installed?

1. Reduction of Noise

The installation of an exhaust fan within the ceiling will assist you in reducing the amount of noise generated by the grow tent. You will benefit if you want your grow room to be silent and if it has an appropriate ceiling system on which you can put an exhaust fan, which is what I recommend.

2. Greater Capacity To Pass The Air

Hanging the exhaust fan in the grow tent will be beneficial because, with the help of this inline fan, you will be able to adjust the distance between the extraction point and the outlet ports. Air will be able to travel through more easily if the space between the two points is increased.

3. Making Several Outlets

The DIY technique allows you to create a large number of exits and intake locations. It is necessary to have these exits and intake points if you are employing a large grow area for your plants.

How Does The Exhaust Fan Work?

With the help of the DIY approach, you may create a number of outputs and input points. When employing a large grow room for your plants, these exits and input ports are required.

What Are Components Do We Need To Install An Oscillating Fan In Grow Tent?

HVAC Exhaust Intake Fan, Low Noise, 4 inch Inline Duct Fan, 100 CFM, VIVOSUN Grounded Power Cord with an Extra Long Length of 5.5′ An input vent is required for the extraction system, which will also function as the extraction point in the grow tent. This vent will be used to evacuate air from the interior of your tent. Intake vents are available in a variety of shapes, sizes, and prices. You must select yours based on the size of your tent as well as your financial constraints. The smaller ones are preferable for usage since they limit the distance over which the air must travel.

2. Ducting

Suitable for heating, cooling, ventilation, and exhaust. AC Infinity Flexible 4-Inch Aluminum Ducting with Heavy Duty Four-Layer Protection, 25-Feet in Length When installing your extraction system, you will want ducting since hanging your fan and filter without it would be difficult to do. It is possible that ducting will be required to connect the internal vent to the motor and the motor to the exterior vent. There are several different forms of ducting, including flexible ducting, semi-rigid ducting, and insulated ducting.

3. Exhaust Fan

A fan will draw the air out of the tent, purifying it and creating the ideal climate for growing your plants. Aside from that, there are several exhaust fans to pick from, but you must make an informed decision based on your requirements, the size of the space, and the fan’s intended purpose.

5. External Vent

With its 4′ hood, the Deflecto Supurr-Vent Louvered Outdoor Dryer Vent Cover (HS4W/18) provides a stylish and functional solution for drying clothes outside. Last but not least, the exterior vent is a critical component of your extraction system. You have the option of mounting the external vent on the exterior wall of your tent or through the hanging rail; the decision is entirely up to you. Another option is to install a backdraft shutter, which will decrease the backflow of air going through the system while simultaneously shutting off the system while the fan is not in use.

How To Hang Oscillating Fan In Grow Tent? Step By Step Guide

Hanging an oscillating fan in a grow tent is a simple process. Some gardeners may not wish to utilize ducting in conjunction with an exhaust fan and filter, and they may choose for oscillating fans rather than an exhaust fan with or without ducting since oscillating fans are less expensive than other types of exhaust fans. Oscillating fans are sometimes preferable to exhaust fans because they may oscillate, allowing for a pleasant breeze to be delivered without blowing on a specific location for an extended period of time.

I’ll demonstrate how to hang an oscillating fan in a grow tent, which I found to be both simple and time-consuming to put up in my experience.

Step 1 – Use Offset Flange

Use the offset flange black with screw holes to attach it to the tent pillars, which is included with the tent. You must connect two black flanges to the back wall of the tent, one to each of the cornerstones of the two corners of the back wall. Make an effort to get the flange as near to the roof as feasible. Then you’ll need to attach a long wood piece to the corner flanges, which will be held together with screws.

Step 2 – Secure The Oscillating Fan

You must fasten your oscillating fan with the wood piece in any location you deem necessary based on your requirements. Once you have completed the installation of the entire procedure, your extraction system will be ready for use. Now all you have to do is connect in the power cord, and your plants will be ready to move inside! If you follow the steps outlined above correctly, you can be confident that your plants will receive the proper airflow and atmosphere to thrive even more than they did previously.

Keep in mind that the technique of removing and installing your plants will determine whether or not your plants develop properly.

What Are The Facts That You Have To Be Careful About While Hanging an Oscillating Fan In Grow Tent?

Using the wood piece, you must fasten your oscillating fan in whichever location you deem necessary based on your needs. Following completion of the installation process, your extraction system will be ready for use. Your plants are now ready to be brought inside; all you have to do now is plug in the power cord. Using the aforementioned process, you can ensure that your plants receive the proper ventilation and atmosphere to allow them to develop more vigorously than they did previously. Throughout this post, we attempted to provide detailed instructions on how to hang an exhaust fan in a grow tent as well as how to hang an oscillating fan in a grow tent to make things easier for you.

Keep in mind that the technique of removing and installing your plants will determine how well they thrive. If you hang your exhaust fan correctly, the quality of airflow you will get will be greater, which will result in a higher yield out of your tent.

Be Careful About The Arrow

Keep an eye out for the arrow on the fan’s surface, which will tell you to the location where the exhaust fan and carbon filter should be installed. It is important not to direct the exhaust fan toward the carbon filter; otherwise, it will have a negative effect.

Take Care of The Oscillation

In the case of an oscillating fan, you should pay attention to whether or not the oscillation is functioning properly. A failure to do so will result in noise when the system is unable to oscillate normally.

Use An Exhaust Fan Calculator

The exhausting system must be checked using anexhaust fancalculator since the general temperature, humidity, airflow speed, and other variables are all aspects that must be considered in order for your plants to thrive properly in their environment.

Maintain The Diameter

Maintain the diameter of the ducting and the exhausting fan, since this is an important safety factor to consider.

Be Careful About The Cheap Ducting Fans

If you can afford better ducting fans, don’t get the cheap ones. They may claim to be able to blow a lot of air based on their CFM rate, but in reality, they don’t have nearly as much power to blow as you may expect. As a result, pick your fan carefully.

Choose As Your Room Size

You must select the duct, filter, and fans based on the size of your room or tent as well as the cost of each item. If you have a tiny tent, you should avoid purchasing a larger fan.

Ensure Better Placement

As much as feasible, hang your exhaust fan as close to the roof as possible since the higher up your exhaust fan is positioned, the more airflow you will obtain from it.

Check Regularly

As much as feasible, hang your exhaust fan as close to the roof as possible, because the higher up your exhaust fan is mounted, the more airflow you will obtain from it.

Seal The System

Try to hang your exhaust fan as close to the roof as possible since the higher up your exhaust fan is put, the more airflow you will obtain.

Make Sure There is No Leakage

Check for leaks at the junction between the filter and the fan if you’re using a carbon filter to ensure that no air is leaking through the filter.

Final Check!

Finally, cleaning your exhaust fan is critical because if it is not cleaned, it will not function correctly and the temperature inside the tent will rise, which will limit plant development.

How do you hang your osciallting fans in your grow tent?

It’s pretty obvious from the title, but how do you hang your oscillating fans in your grow tent? Over the years, I’ve gone through a number of oscillating fans, and they don’t seem to last very long at all. One of the primary issues is that when there is negative pressure, the sides and back/front of the tent are sucked in, which inhibits the oscillation of the fan, causing it to stick and make a loud clicking sound as it is unable to move. As the plants grow in height, the problem becomes more severe since the center of the sides is sucked in the most.

My towel was placed behind the clip-on bit, which is tied to a bungee by the hook and fixed to a corner pole with cable ties by the hook.

The fans normally survive approximately 12-14 weeks when they are hung upside down because the gearing finally wears out and they cease to oscillate.

Fortunately, there are two stores close. I’ve also tried several off of eBay, and they’re much worse than the others. What method do you use to hang yours?

Grow Tent Fans – Sizes, Placement, Setup, FAQ (Updated 2022)

It is critical to have adequate circulation in your grow tent if you want to avoid mold and powdery mildew from forming on your cannabis. Throughout this article, I’ll cover all you need to know about choosing an inline fan for your grow tent and how to correctly install and configure it as well. How to choose the right grow tent fan size and power rating, where to install the fan, how to set up your grow tent fan, and what additional accessories you’ll need are all things I’ll assist you with.

Selecting the proper grow tent fan size and power:

“What is the right grow tent fan size?” is definitely one of the first questions you’re thinking about. as well as “What is the recommended grow tent fan power?” Generally speaking, when it comes to replenishing air in a grow room, the rule of thumb is that you should be able to replace all of the air once each minute. That is the CFM rating, which you will learn more about further down. In order to keep your grow tent cool, the fan diameter will be decided by the CFM (cubic feet per minute) rating that you want.

So don’t be concerned about having the correct CFM rate.

Then there are a few other factors, such as a 25 percent drop in fan power if you include a carbon filter, and a 30 percent loss in fan power for each 90-degree curve in your ducting.

The proper size fan for a 4×4 grow tent:

Let me give you an example of how to calculate the area of a 4×4 grow tent, which is a fairly typical size among indoor growers: The majority of 4×4 tents have dimensions of 48 in x 48 in x 80 in. As a result, the total volume of air in a 4×4 grow tent is 4ft (length) x 4ft (width) x 6.667ft (height) = 106.67 cubic feet (4ft (length) x 6.667ft (height). However, this does not imply that you require a 106 cfm fan. When you consider that a carbon filter will lower your fan efficiency by 25 percent, and that one 90 degree duct bend would reduce your fan efficiency by another 30 percent, a fan that produces 215cfm will produce 112cfm (200cfm x 0.7 x 0.75).

What size fan is needed for other grow tent sizes?

(Click on image to expand) It is important to note that grow tent inline fans are not made to the precise CFM output you want, thus you may have to go over by 50-100cfm when selecting a fan for your grow tent. I recommend using a fan with variable speed settings, such as the AC Infinity S or T Series, so that you may modify the CFM to meet your precise requirements.

Each of the AC Infinity fans listed below has ten speed options, so if you just want 100cfm, you may get the most basic model, which is a 205cfm fan, and run it on the middle speed level to achieve that volume of air.

Grow tent fan placement:

Depending on where you want your grow tent fan to be, you have two alternatives. It is possible to work either inside or outside the grow tent. What’s the difference between the two? If you pick outdoors, the fan will draw air from the interior of your tent to the outside through a duct located on the top corner of your tent, allowing you to be more comfortable. You’ll want the fan and filter (if you’re using one) hanging near the top portion of the tent, where the warmest air will naturally travel to keep it cool inside.

Hangers are not often included with fans, so double-check that you have them.

If you decide to place the fan outside, you’ll need to figure out how to get it to rest in a comfortable position.

Because of the fan’s ability to produce a low pressure condition within the tent, when air is blasted out, new air is naturally drawn into the tent.

Grow tent fan setup:

Yes, the diameters of your inline fan and duct will need to be the same at the place where they connect.

Passive or Active Air Flow For Your Grow Tent?

The sorts of fan sets you may utilize in your grow tent or growing room are passive and active. Passive fans are the most common. The difference is whether you want air to passively re-enter your grow tent or if you want it to aggressively re-enter your grow tent. Passive grow tent air circulation relies on a single inline fan to evacuate hot air from your grow room, reducing the need for additional fans. When air is forced out of your enclosed grow area, the pressure in the room drops to a negative pressure, which means that air from outside the tent or room should naturally be drawn in via any openings to replace the air that has been forced out of the space.

  1. If you want to guarantee that the air returning to the tent is being filtered, or if the air returning to the tent is not returning rapidly enough, active grow tent air replacement is the best option for you.
  2. Simply ensure that you have the right size ducting (which should be the same diameter as your fan), duct clamps, hangers for hanging, and zip ties before beginning (make sure zip ties are long enough to go around the diameter of your carbon filter).
  3. To install the filter, just attach ducting to the side of your fan that is responsible for sucking in air.
  4. Clamps should be used on both sides (usually provided).

If you’re using an active air flow configuration, I’d recommend operating both fans at the same speed to ensure that the quantity of air escaping the grow tent equals the amount of air returning to the grow tent.

How to install a grow tent fancarbon filter inside your tent:

Attach the hangers to the support bars that run along the roof of your grow tent. You’ll need enough for the fan and the ducting, so plan accordingly. Make sure they’re the right length for the fan you’ll be hanging. Keep in mind that heated air rises to the top of the tent, so avoid hanging the tent too low. 2.Attach zip ties or metal brackets to the attachment area of your grow tent fan: Place zip ties or metal brackets to the attachment region of your grow tent fan. Zip ties should be used to connect hangers.

In order to use your grow tent fan, you must first connect your carbon filter to the intake side of the fan (the side that sucks air in).

You may either connect it directly to the fan or use ducting to attach it to the fan.

Attach the grow tent duct sleeve to the fan ducting by wrapping it securely around it.

Other Inline Fan Installation Notes:

The setup is straightforward; it took me no more than 30 minutes to complete my AC Infinity T4 installation. The most efficient design would be to route the duct out a window so that the hot air from your tent does not just blow into the room where your tent is placed, where it would be sucked back in and render the entire operation ineffective. Not everyone has the benefit of having a window in close proximity to their camping site. In that case, if you’re compelled to blow tent air into the same room where the tent is placed, I highly recommend investing in a portable air conditioner to re-cool the air before sucking it back into the tent through the bottom tent windows.

Does It Matter What Carbon Filter I Choose For My Grow Tent Fan?

When selecting a carbon filter for your grow tent fan, the one thing you want to be certain of is that the diameter of the connection point on the fan and the filter are the same. Make certain that your inline fan is equipped with a four inch carbon filter if your fan is four inches in diameter. Apart from that, there isn’t much of a difference between carbon filters; they’re simply large metal canisters that filter your air through charcoal to remove impurities and odors from it.

Do I Need an Oscillating Fan in Addition to my Inline Fan?

Even though the inline fan removes and replaces the air in your grow tent, it performs a poor job of circulating the air. As a result, you should think about including an oscillating fan in your grow tent to keep the air circulating and prevent mold and mildew spores from taking root. It will also aid in the distribution of fresh air for the benefit of the plants. There are little affordable oscillating fans that you can attach into the grow tent poles if you have a look at the fans I’ve listed below.

Which Grow Tent Fans I Recommend:

As long as you’re willing to purchase the ducts and hangers separately from the fans, AC Infinity offers fantastic grow tent fans. Purchasing the ducts and hangers is simple – simply match the duct diameter to the fan diameter. What is it about the AC Infinity fans that makes them so much superior than the competition? This fan is equipped with a programmable controller, which allows the fan to switch on in response to a range of different scenarios. For example, you may program the fan to turn on when the humidity reaches a given threshold.

  • You may also set a timer and receive alarm notifications.
  • When my AC Infinity T4 was running at maximum power, I was pleasantly pleased at how quiet it was.
  • This results in the fan motors being loud.
  • Quiet Inline Duct Fans With Temperature and Humidity Control – CLOUDLINE SERIES Them fans are priced similarly to other fans without the technological characteristics, therefore it makes financial sense to purchase one of these instead of another fan.

The fans are available in three sizes: 205cfm, 351cfm, and 750cfm (4-inch, 6-inch, and 8-inch). Click here to see whether they are available on Amazon.

VivoHome Inline Fan Kit

If you don’t want to go through the trouble of sourcing all of the components separately, this kit includes a fan, 8 feet of ducting, clamps, hangers, and a carbon filter. It is available in two different sizes to accommodate different grow tent sizes. With this kit, the main drawback is that the fan cannot be programmed to come on when particular conditions are fulfilled, such as a certain temperature or humidity. The fan has a simple on/off switch. Despite the fact that some customers have stated that they are content with the fan running all of the time.

Secret Jardin Clip On Monkey Fan for Grow Tents:

Secret Jardin created this 6-inch clip-on oscillating fan with a grow tent owner in mind when they created this product. The clip is designed to attach securely on the support poles of grow tents. The fan will ensure that your grow tent has adequate air circulation, which is necessary to avoid the growth of mold and powdery mildew. I’d recommend using one of these oscillating clip fans in conjunction with an inline fan in order to maintain the ideal growth environment in your grow tent.

Keeping Your Grow Tent Cool

When it comes to keeping your grow tent temps under control, you may want more than simply an inline fan. My best recommendation, without requiring you to read the entire post, is to consider purchasing a portable air conditioner for the room in which your tent is placed, or to consider adding CO2 to your growing environment, which allows you to grow a few degrees hotter than usual. See my whole post on decreasing grow tent temps for more information.

Ideal Grow Tent Temperature and Humidity for Growing Cannabis:

The optimal temperature for cannabis plants is between 70 and 80 degrees Fahrenheit (23 degrees Celsius). Consequently, consider yourself fortunate if you have a modest grow light in a small tent, or other circumstances that allow you to maintain those temps without using an inline fan. During the seedling and vegetative stages of the cannabis plant’s life cycle, 60 percent to 70 percent humidity is ideal. When cannabis plants are in the blooming stage, they grow best when the humidity is between 40 and 60 percent.

As your plants mature, they will begin to use a significant percentage of the CO2 that is available in your growing environment.

I developed numerous useful lists and tips to assist you in completing your home improvement project the right way, in addition to determining the proper fan size for your needs. The following are some other articles I strongly recommend: Choosing the Proper Size Grow Tent, This Year’s Best LED Grow Light List, and Understanding Grow Light PAR PPFD and Wattage, among others. Last but not least, don’t forget to check out myhome page for a comprehensive collection of useful resources.

Grow Tent FanCarbon Filter FAQ:

You’ll just need 30-45 minutes to complete this task.

What should I do if there isn’t a CFM output for my exact grow tent size?

The AC Infinity fans feature a number of different speed settings to choose from.

As a result, if you just want 100cfm, you may get the 205cfm (smallest model) and utilize the middle of the ten available speed settings.

If I’m buying parts separately, how do I know if they’ll all fit together?

The diameter of all of these components is the same. If you purchase a 6′′ fan, be sure you also purchase 6′′ ducting and a 6′′ filter to complete the installation. That’s all there is to it, really.

Do I need to hang the carbon filter?

The carbon filter should be placed at the top of your tent in order to capture the warmest air because it is where air will reach your fan from the outside. It would be inefficient to hang the filter low or to place it on the floor, for example.

Which end of the grow tent fan do I connect the carbon filter?

Connect the carbon filter to the “front” of the fan, which means that the fan is sucking air through the filter rather than expelling air through it, and that the fan is running continuously.

What size fan will fit in my grow tent?

Most grow tents accommodate 8-inch ducting, while some may only accommodate 6-inch ducting.

What if the size of my duct is too big for the duct hole on my grow tent?

If your grow tent outlet is 6 inches in diameter and your ducting is 8 inches in diameter, you’ll need to purchase a ducting reducer.

There’s too much negative pressure in my grow tent

Alternately, reduce the speed of your fan and, if possible, open up the passive air intake windows on the bottom of your tent even more, or consider installing an active air intake fan, which works in the same way as your other fan but is mounted on the bottom of your grow tent and pushes air into the growing chamber.

Can you wash or clean carbon filters after extended use?

It is possible to clean a carbon filter using compressed air. The filter may be used for up to one year before it has to be cleaned.

Can you place a carbon filter on each side of your fan?

Yes, although it may result in a slight reduction in the power efficiency of your fan. Check to see if your fan is strong enough to manage the additional carbon filter load.

Do all carbon filters come with pre-filter wrap for the exterior of the canister?

Pre-filter wrap is not included with all carbon filters; thus, if you want a pre-filter included, be sure to check the product page specifics before purchasing.

What’s the largest outer dimension of my carbon filter?

Increase the output size by approximately 2 inches. On a 4 inch carbon filter, the canister diameter would be approximately 6 inches in diameter.

How long do carbon filters last?

Carbon filters are designed to endure for at least one year of continuous usage.

Do I need inline and oscillating fans in my grow tent?

Inline and oscillating fans serve various functions in the grow tent, so it’s a good idea to use both if you have the option. : grow tent fan oscillating

Oscillating fans

Only a few months ago, I would have walked past this topic and said to myself, “Pfftt. go out and purchase a fargin fan and set it to oscillate dick.” Now that I’ve gone through two brand new Lasko fans, one 16-inch and one 12-inch, I’m ready to move on “, the other 18”, as well as three 18″ers that I’ve had for years with no problems other than linty dirt that accumulates every now and then. But the little tiny piece of plastic that breaks in the same place every time when I hang them upside down in my tents (I imagine it’s because I hang them upside down when they aren’t meant to be hung upside down) because if I put them right side up, the gigantic base takes up a good 18-24 inches of floor space when they aren’t meant to be put right side up.

  1. Others are orbital, some are oscillating, and most significantly, some are wall mounted, which is ideal for my situation.
  2. Right, you’d mount it on a piece of plywood and then hang it from the tube frame you’re picturing.
  3. I’m not seeking to spend $100 on a fan, but considering that I’m passing through $35-40 fans left and right, maybe a $100 fan is the best solution.
  4. According to my understanding, having more moving parts means that things are more complicated, and complexity means that things break more frequently.
  5. I purchased two oscillating 48s for $60 each “I have tower fans that are completely ineffective; they only move the air around 45 degrees; I need something that moves the air as near to 90 degrees as feasible.

My understanding is that the towers are adequate for blowing air around the bottoms of plants and for keeping air flowing around the top of the soil and everything within 2 feet of it, but other than that, they are worthless to me.

Best Fan For Grow Tents (Reviews And Comparison)

Beginning growers are always eager to avoid the use of fans. I was in the same boat. I assumed I could just take any fan I had lying around and put it in my grow tent. I was wrong. And it has the potential to function. However, it is frequently insufficient. All plants, with the exception of the tiniest, require both an inline fan and an oscillating fan. At the very least. In addition to being reasonably priced, even the highest-quality fans for your grow tent may be found online. It’s only a matter of knowing which models are the most cost-effective.

Let’s get right in and get started with a brief comparison of the best inline and oscillating fans currently available on the market.

Best Fans For A Grow Tent Compared

The fans listed below are the best available alternatives on the market. We offer a great selection of inline and oscillating fans to choose from. The best bargain is represented by the top selections. After that, we offer recommendations for the greatest affordable models as well as the finest quality selections available.

Best Inline Fan For Grow Tent: AC Infinity Cloudline T6

The AC Infinity Cloudline T6 is, by a wide measure, the greatest overall inline fan on the market. It is not prohibitively costly when you consider everything it can accomplish, and it was created expressly with farmers’ requirements in mind. Many inline fans are straightforward, similar to the types of fans that you may see placed within computer casings. They simply turn on and off, often in response to a thermostat setting. The T6 is far more intelligent, and it comes equipped with several incredible features that make the asking price well worth it.

  1. Many inline fans that have programming capabilities are difficult to configure because of the interface’s numerous panels and menus.
  2. The ability for airflow to self-adjust is a trait that is extremely useful in keeping things moving.
  3. The Cloudline T6 has a total of ten speeds.
  4. The three available speeds are not always sufficient, depending on the other environmental conditions present within your tent.
  5. The reason this is beneficial is because many people utilize a wireless sensor that appears to be always disconnected or experiencing connectivity troubles.


  • The wired sensor will not disengage
  • Airflow that can be adjusted on its own
  • Exceptional value for the money. 10 different speeds
  • More than 5000 favorable ratings


The Comfort Zone CZ16W is a 16-inch wall-mounted three-speed fan with an adjustable tilt. It has three speeds and an adjustable tilt. It oscillates, allowing it to provide flowing air across the whole grow space. This is not a high-end fan with temperature and humidity meters attached to it. It is a straightforward, no-frills wall mount fan that will circulate a significant amount of air in a medium- or small-sized grow tentor room or greenhouse. One of the reasons it is our top pick for the finest oscillating fan is because it has everything you could possibly want in a durable, well-made device without adding any unnecessary features or sophisticated technology that would make things more difficult and therefore more expensive.

  1. Three speeds aren’t something out of the ordinary.
  2. The inclination may be adjusted, which is convenient.
  3. Fixed fans with no tilt severely restrict your installation options because they must be installed at precisely the same height as your plants.
  4. The oscillation of this fan is quite smooth and pleasant to the touch.

I just find it irritating when the movement of an oscillating fan is choppy and uncoordinated. There are no irritating jerks when the fan catches up to the oscillation motor with this fan, which makes it a pleasure to use.


  • Pull cord control makes operation simple
  • The design is sturdy, with a metal safety grill for further protection. Three different speeds
  • An adjustable tilt
  • And wall mounting capabilities.


  • It would have been good if the atimeror had shut itself down.

Best Budget Inline Fan:Vivosun 4 Inch Inline Duct Fan

The Vivosun 4′′ Inline is my favorite budget-friendly inline skater on the market. When you purchase one of these, don’t expect any high-tech features or gadgets to come included. This is a 4′′ fan that may be used as an intake or exhaust fan depending on the application. Because of its 4′′ diameter, it is compatible with the widely used 4′′ duct tubes. It is made completely of metal (as opposed to plastic, as some other models are) and rotates at 2930 RPMs. Neither speed switches nor thermostats will be found on this device.

  • Unless anything becomes entangled in the fan, it is not particularly heavy, and it requires little maintenance.
  • There are no additional headaches associated with using this little fan, which will circulate a lot of air without causing you any discomfort.
  • It is also available in a 6 and 8 inch variant, but the 4 inch version is the most common because it is normally large enough to accommodate most small to medium sized grow tents.
  • For additional information, please see our fullVivosun grow tent review.


  • Simple metal construction with only a few potential pitfalls
  • It moves a lot of air despite its little size
  • It does its function really effectively. Very reasonably priced


  • To turn off, the device must be linked to a power switch.

Best Budget Oscillating Fan:PELONIS PFT30T2ABB-V

The Pelonis PFT30 oscillating fan is a powerful oscillating fan with a low barrier to entry. In spite of its modest size, this 12 inch low profile fan can move a significant amount of air for such a little fan. It is intended to be used as a table fan, but it may also be put on the floor to help circulate some of the cooler air that tends to sink deep in your grow tent when it is hot outside. It is a surprisingly strong tiny fan that does not produce excessive noise. Its overall height is slightly about 19 inches, and it has three different operating speeds.

The buttons were a bit bothersome, and I would have preferred a dial instead, but this is a small complaint.

The main unit housing has the appearance of being susceptible to cracking, and the fan cage is made of thin metal that will bend and dent with severe use.

An affordable small 12′′ oscillating fan that will do the job while not costing you a lot of money is presented here.


  • For its small, it moves a significant amount of air. Because it is only 19 inches tall, it can be placed practically anyplace in your tent. It is possible to change the tilt or the speed. It comes with a one-year warranty.


  • It does not appear to be as durable as more costly alternatives
  • Does not include a means to put it on the wall, so you’ll have to come up with a creative solution

Highest Quality Inline Fan:AC Infinity Cloudline T8

When it comes to quality, the AC Infinity Cloudline T8 is the best alternative I could find in this price range. It is not the cheapest 8-inch duct fan on the market, but it is the one with the most options and the best degree of quality available at the time of purchase. There are two connected sensors that will feed temperature and humidity data to the fan, and it is a button-controlled duct fan with a beautiful LED readout display. Due to the fact that it was specifically built for grow rooms, this fan understands exactly what it is doing.

It is simple to install and can be clipped into your existing 8′′ ducting.

In order to achieve this extra silence, a pulse width modulated motor was used, which not only produces less noise but also consumes less power at the same time as it produces more noise.

If you already have another AC Infinity inline fan in the same application space, this device may connect to it and interact with it through Ethernet.

When you handle it or put it together, you can tell that it is of high quality. Comparing this product to other similar items in the same price range, it appears to be significantly more well-built.


  • Motor that is exceptionally silent
  • 8-inch standard size
  • The accuracy of a wired sensor is higher. It is delivered with duct clamps. Extremely well-constructed


My research revealed that the Hurricane 20′′ Wall Mount fan is the highest-quality oscillating fan available. When it comes to a fan that will endure for years and not break on you. while still moving a significant amount of air. and you have a reasonable price, this is the fan for you! This fan is classified as a high velocity fan, which implies that the blades move incredibly quickly while the fan is running at a high speed. It is also a 20-inch fan, which means the motor is rather strong.

However, if that is not enough to terrify you, remember that these blades are hard metal blades, so think of this as a high velocity finger removal machine, and keep it out of the reach of children and animals.

It is constructed in the style of a tank, with heavy-duty metal fan blades and a cage.

The tilt is not as dramatic as some other wall mount fans I have seen, but the 90 degree oscillation makes up for it a little bit in terms of cooling power and comfort.


  • It is constructed in the manner of a tank. A massive volume of air is moved by a powerful engine
  • Controlled by a lever, it has three speeds and is ETL approved.


  • For a wall mount fan, it is a little pricey
  • It has less tilt than some other versions.

Grow Tent Fan Buying Guide

In the event that you are unsure about what type of fan you want or which characteristics are most important, our shopping guide will help you to sort things out. We’ll start with a brief overview of the many types of fans available.

Different Types of Fans

For gardening purposes, there are three fundamental types of fans that are commonly used: Each type of fan is designed to perform a certain function. The majority of serious growers will require all three categories in order to run a profitable enterprise. It is vital to have airflow in addition to humidity control and temperature control, which may be achieved by a central A/C unit, a window mount unit, or a portable unit. This is due to the reasons described above. It is not sufficient to just regulate the temperature and humidity.

Inline Fans

These are fans that are normally installed within a duct system or that are used as exhaust fans that vent directly to the outside air stream. However, many of the higher-end devices are fitted with sensors and on/off switches, which is not always the case. These fans are referred to as inline fans because they are installed directly in line with the ductwork and function as an integrated element of the ventilation system, as opposed to a freestanding fan that circulates air around the room. A real grow tent will require at least two inline fans, one for intake and one for exhaust, in order to function properly.

Smaller tents are often equipped with only an exhaust fan.

Oscillating Fans

In a tent or a room, oscillators are fans that circulate air around the space. Optically symmetrical fans, which are used in a closed system to bring in air from the outside or push air from inside to the outside, prevent the internal air from becoming stale. Inline fans are used to bring in outside air or push air from within the system. They also play an essential function in agitating your plants by acting as an artificial wind source within your closed-system environment. Natural forces are required to move plants around in order for them to remain healthy, and because you do not have any natural wind inside, the oscillating fans are taking the position of natural wind.

Hot spots will rapidly appear in any space, but especially in one that has grow lights and other heat sources.

Moving air from one location to another will help to maintain more consistent ambient temperatures throughout your home. Moreover, the circulating air helps to dry the plants, which helps to prevent mold from growing on the leaves.

Static Fans

These are the standard fans that you can find everywhere. They are not oscillating or moving in any way. Static fans, on the other hand, are always stationary. They can either be placed on the floor or attached to buildings. The usage of static fans is most often required in scenarios when you need to continually move air in a specified region of the room while maintaining the same location of the airflow over time. A good example of when you would require a static fan would be if you had an area of your building where multiple lights were concentrated in one location.

Fan Size

The greater the size of the fan, the greater the amount of air it will move. This is a straightforward notion that makes determining the appropriate fan size simple. Of course, given the fact that many of us are working within limited space limits, this is not often the primary issue. With a large warehouse, you could simply purchase as many of the largest fans as you could afford and utilize them to move as much air as possible.


Inline fans are available in a variety of sizes. The most typical fan sizes you will find in grow tents are 4′′ and 6′′, with the occasional 8′′ or 12′′ fan thrown in for good measure. The grow tents do go even bigger, but once you get over 8 inches, you are dealing with heavy-duty enormous areas rather than the typical grow tent environment.


Oscillating fans are available in a variety of sizes as well, however for the majority of applications, a 12′′ or bigger fan is required, which are the most popular sizes. If you have a standard grow tent, the chances are strong that you will be looking for a tiny oscillating fan for grow tent use that is around 12 inches in diameter. These are capable of moving a large amount of air while taking up little area.


Both static and oscillating fans are available in the same sizes as oscillating fans. The clip-on 8-inch or standard-size floor fans are the most frequently seen in our application. The majority of box fans that sit on the floor are around 20 inches in height. You can select the appropriate size for your needs based on your individual circumstances.


Because fans are so vital, it makes sense to invest in the greatest ones you can afford with the money you have available to you. Because they are normally not that costly, you can usually purchase a substantially better fan for only a few dollars more than you would pay for a lesser-quality fan. When it comes to fans, you want something that will endure a long time and circulate a lot of air. In most cases, you want it to do it with the least amount of noise possible.

There are many badly constructed fans available for purchase at incredibly low prices, so exercise caution! Following the recommendations we’ve made here, you may be certain of receiving a high-quality equipment at an affordable price.

Best Fan For Grow Tent: Final Thoughts

At the very least, an oscillating fan will be required if you are growing marijuana in a grow tent or greenhouse. Most likely, you will also want an inline fan to exhaust the heat generated within the tent. In bigger tents, a second inline fan will be required to draw in fresh air from the outside. All of the fans on our list will provide you with excellent service. Except if you have a limitless budget, we strongly recommend that you stick with our top picks because they are the most value for your money.

They are nice fans, however you can buy much better ones for not much extra money if you shop about.
