How Do I Hang Fans In My 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.

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 tiny end of the ducting and attach 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 opposite 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 using the hanging rail connector.

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.

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?

The Influence of the Ventilation System on Plant Growth It is something that is utilized to collect waste from a space outside of it that is referred to as an exhaust fan. For example, if you utilize an exhaust fan in your plant grow room, it will remove the foul odor, the air, the waste, and the humidity from the area outside of the tent. It is necessary to position the fan at a location where air may readily travel through the fan. The fan’s capacity to circulate air is determined by the height of the ceiling, the size of the space, and your ability to hang an exhaust fan in a grow tent in the appropriate manner.

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

Aluminum High Speed 1620RPM, 940 CFM, IPower 12 Inch Shutter Exhaust Fan with Aluminum High Speed 1620RPM, 1-Pack, Silver Any extraction system would be incomplete without a fan. When you use a fan, it will draw the air out of the tent, purifying it and creating the ideal climate for growing your plants.

Additionally, 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 intended usage of the fan.

4. Exhaust Fan Calculator

In order to calculate the extraction level required for your plants’ development in a grow tent, you will need an exhaust fan calculator. There is a straightforward calculation that may be used to quickly compute the extraction level of an exhaust fan. The formula is as follows: Fan volume (m3/hr) = Length(m) x Width(m) x Height(m) x number of air changes per hour Keep in mind that using ducting with the same diameter as your fan will improve the performance of your fan. Reduced diameter will result in a reduction in the quality of the job performed by the exhaust fan.

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. The more precisely you hang your exhaust fan, the higher the quality of the airflow you will receive and the greater the yield you will receive from your tent will be.

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

In order to properly hang an oscillating fan in a grow tent, there are a few considerations that must be taken into consideration. Never allow your fan to blow wind directly into or into your plants. It should only blow wind around the plants, not directly upon them. In addition, excessive wind will cause your plants to be clawed by the wind. When an excessive amount of airflow blows onto plants, it causes wind-burned, which causes the plants to claw. When you notice the clawed plants, you could assume that the clawing is the result of overwatering or underwatering, but the most likely reason will be over-winding of the plants.

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

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 flourish properly.

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

Check the humidity level on a frequent basis since plants are constantly exhaling water vapor into the air, which can cause difficulties within the tent if the humidity level is too high.

Seal The System

It is necessary to seal the entire exhausting system after utilizing it since it is beneficial in increasing the efficiency of the system. When employing a carbon filter and an exhausting system, it is critical to ensure that the air is adequately ventilated from the grow room; otherwise, the air will flow through without being properly vented. The major function of the exhausting fan is to provide suction, which is very hard to achieve without a seal.

Make Sure There is No Leakage

After using it, you must completely close the exhausting system since it is necessary to increase the efficiency of the system. When employing a carbon filter and an exhausting system, it is critical to ensure that the air is correctly ventilated from the grow room; otherwise, the air will flow through without being vented properly.

When it comes to exhausting fans, suction is their principal function, which is nearly hard to do without sealing.

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.

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.

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.

The bottom of most grow tents is equipped with passive air intakes, which are netted openings that let fresh air to enter the tent. 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.

  • 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.
  • 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).
  • To install the filter, just attach ducting to the side of your fan that is responsible for sucking in air.
  • 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.

5.Connect ducting to tent exhaust opening: Connect the ducting to the tent exhaust entrance located at the top of your grow tent. 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.

  1. You may also set a timer and receive alarm notifications.
  2. When my AC Infinity T4 was running at maximum power, I was pleasantly pleased at how quiet it was.
  3. This results in the fan motors being loud.
  4. 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 temperatures under control, you may require more than just an inline fan. My best advice, without requiring you to read the entire article, is to consider purchasing a portable air conditioner for the room in which your tent is located, or to consider adding CO2 to your growing environment, which allows you to grow a few degrees hotter than usual. See my full article on lowering grow tent temperatures 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.

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.

How to Ventilate Your Grow Space

You must have adequate ventilation in order for your plants to flourish. By giving your plants with fresh air from outside your grow tent, you are supplying them with CO2, which is necessary for their photosynthesis. Meanwhile, removing the air inside will help to keep the temperature and moisture buildup under control, avoiding mold and mildew from growing on your plants’ leaves and so hindering their ability to thrive. The extra benefit of refreshing the air within is that it helps to eliminate unpleasant smells.

Essential Grow Tent Parts

Assuming you have previously chosen or purchased your grow tent, this tutorial is equally useful if you are working in a grow room. This is a list of the three most important components that you’ll need to put together while building a ventilation system:

Inline Duct Fan (Active Exhaust Fan)

An inline duct fan, also known as an extractor fan, is a device that is used to exhaust hot and humid air from within a growing chamber or tent. Even little variations in temperature and humidity may have a significant impact on your chances of generating a fruitful harvest. Furthermore, unregulated heat and humidity cause poor growth circumstances, resulting in your plants being unable to absorb water or simply failing to make it through the day. The use of an inline duct fan in your grow room is essential for controlling the climate in your growing environment.

Using an active exhaust fan to draw in cooler air can assist you in maintaining a comfortable inside temperature level.

In ventilation systems with passive intake, inline duct fans also serve as a vacuum, drawing in new CO2 from the outside air and bringing it into the system.

Duct Tubes

Inline duct fans are attached to your grow room using ducting that is clamped or glued in place. The ducting serves as a channel to divert stagnant air away from your grow space. They are typically constructed of aluminum, although they may also be multilayered to provide additional protection against rips. Its size and bends have an impact on the performance of your inline duct fan, but we’ll get into that later.

Carbon Filter

A carbon filter will be required in order to prevent scents from traveling to your garage or closet. This device, which is also known as a carbon scrubber, removes the smell of plants from the air, capturing the odor and neutralizing it. Carbon filters are a must-have for growers that have to cope with very strong odors. They are also used to trap pollen and spores, which helps to keep the air clean for farmers who suffer from allergies or respiratory problems such as asthma.

Typical Grow Tent Setups

There are several configurations for these components that may be used to create airflow into your grow environment. As a standard configuration, the fan and the filter are placed inside, which makes it easy to control while also dampening the noise from the fan. If air is being drawn out of your grow room, one or both of these components can be placed in any sequence within the ventilation chain. It is possible to customize your ventilation system in at least four different ways in order to meet your requirements.

The fan and/or filter can be placed outside of the grow tent in this situation.

Because heat rises to the top of the building, venting that hot air at that point will improve the efficiency of the ventilation process.

What Size Inline Fan do I Need?

There are many different sizes of grow areas, and each one requires a particular amount of airflow to be properly ventilated. It is critical for maximum plant growth that stale air within your grow room is exchanged with fresh air from the outside of your grow area. CFM (cubic feet per minute) is the unit of measurement for this number. To determine the quantity of airflow required for your grow room, first calculate the volume in cubic feet of the space. Most grow tent specifications are offered to you in inches; thus, you must convert the size of your space from inches to feet.

This will match the capacity of your grow room, and the needed airflow will be equal to this value in cubic feet per minute, or CFM, as well.

When the dimensions are added together, the result is 72 ft 3 in length.

Because the volume of a grow area is equal to the amount of CFM necessary to air it per minute, the base CFM for this grow tent is 72. Keep this amount handy since you’ll need to adjust it to account for the ducting, carbon filter, and any other accessories you decide to install.

Factoring in Accessories

In order to boost your base CFM, you must multiply it by the efficiency percentages of your accessories. Adding components to your grow room, including as ducting and carbon filters, may limit fan performance, which will have an impact on the fan size you require. When it comes to ducting, the number and sharpness of its bends play a role in determining the resistance to airflow. As a result, airflow decreases the longer it needs go, making a straighter ducting path more effective. The greater the sharpness of the curve, the greater the severity of the efficiency drop; a 30° bend reduces airflow by 20%, while a 90° bend reduces airflow by 60%!

  1. If you are utilizing LED grow lights, you must also take into consideration their heat production, which can raise your necessary CFM by as much as 50%.
  2. Because the efficiency of accessories on the market might vary substantially, you can utilize approximated efficiency percentages based on the type of component you are using.
  3. This amount is multiplied by the efficiency % of each component to arrive at the final result.
  4. Adding in the heat output of your grow lamp (about 50%) gives us a needed CFM of 249 cubic feet per minute.
  5. The following is a breakdown of this calculation: Multiplying your base CFM (72) by the percentages of ducting (20 percent), carbon filter (60 percent), silencer (20 percent), and grow light heat (50 percent) of your choosing will provide about the 249 CFM you require.
  6. This will let the fan to operate at lower speeds while remaining quieter, as well as providing additional area for future expand space system growth.
  7. PWM-controlled EC motors are also acceptable in terms of acoustic performance.

How to Manage Grow Space Noise

There is no question that you will hear some noise when employing a high-powered fan to air your grow environment. You wouldn’t want to spend an extended period of time in an area with excessive noise pollution or catch the attention of your neighbors. Fortunately, you can plan your component selection with noise reduction in mind, and you can take further steps to make your grow area as as quiet as possible. Making the decision to choose a fan with speed controls and a CFM rating that is 25 percent more than your minimal need will allow you to run the fan at lower speeds without compromising performance.

If you want to further muffle the sound of your active exhaust fan, you may attach a silencer to it, which will lessen the sound of the intake fan. You may also choose to use insulated ducting instead of regular ducting to lessen the whooshing wind noise that occurs during the installation.

Where to put oscillating fan in grow tent?

Dora Tremblay posed the question. Score: 4.7 out of 5 (48 votes) Put it in the center of a square tent and you’re done! (use multiples in larger areas). If you have any other type of fan, be extremely cautious to set it on the floor and direct the air upwards in order to guarantee that the temperatures at the top and bottom of your growing space are more evenly distributed.

Where should grow tent fans be placed?

In general, we recommend that you put your extractor fan and all other components of your exhaust system within your grow tent in order to reduce noise contamination. But if you’re running out of room or having trouble keeping the heat under control inside your tent, feel free to set up your fan outside of the tent.

Should I run my fan 24/7 In my grow tent?

Flowering is the most critical stage of the entire growth process, and this is especially true for cannabis cultivators. During daylight hours, both exhaust and oscillation fans should be functioning, as they should always be. As a result, the ideal approach is to have scrubber fans running 24 hours a day, seven days a week throughout late blooming stage.

Does Grow tent need intake fan?

Passive air intake may be used in larger grow tents as well, although larger grow tents would necessitate larger 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.

What size exhaust 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. There were 44 questions that were connected.

  3. 1.5 Install a Swamp Cooler in the Grow Tent

Should I open the flaps on my grow tent?

Some tents are equipped with built-in ventilation flaps at the bottom, which are particularly useful in hot weather. If you open one of them, it will aid your intake fan in drawing in more fresh air and overcoming the extra negative air pressure that a grow tent cannot withstand. Otherwise, if the tent is in a dark room, it is OK to proceed with it.

Do you need to vent grow tent outside?

It is vital to have adequate ventilation in your grow tent. Plants can get anemic and eventually wither and die if they do not receive enough fresh air and exhaust enough stale air. We all require fresh air, and a closed environment such as a grow tent is not equipped with any ventilation by default.

What size extractor fan do I need for Grow tent?

In order to determine the extractor fan size for your grow room or tent, multiply the grow room volume (cubic feet), the carbon filter factor (+25 percent), the insulation factor (20 percent), the ducting factor (+10 percent for 10 feet), and the light factor (+10 percent for 1000W) by the following formula: You’ll be given the fan size in cubic feet per minute (CFM).

Can I use a fan to dry my buds?

A fan, automobile heater, and a PC fan are all examples of what is available.

Any fan is a good option since appropriate marijuana drying does not offer direct air to the buds; for quick drying, direct air is one of the greatest possibilities; warm air is also a good option because it helps the buds dry faster (many people use PC fan, because of its warm air).

When should I run my carbon filter?

To put it another way, carbon filters need to be replaced after 18-24 months of continuous (24/7) use. Depending on how harsh the environment is, they can endure up to 4 years. This lifetime, on the other hand, is dependent on the carbon quality, consumption, humidity, and plant species, among other factors.

How do you place a fan in a grow room?

Air circulators should be pointed at a wall or ceiling to maximize efficiency. Put it in the center of a square tent and you’re done! (use multiples in larger areas). If you have any other type of fan, be extremely cautious to set it on the floor and direct the air upwards in order to guarantee that the temperatures at the top and bottom of your growing space are more evenly distributed.

Do you need fresh air in a sealed grow room?

Simple definition: A sealed room is a growth environment that has no openings or air exchanges with the outside world or with any other room in which it is located. It is not required to be completely airtight; nonetheless, the closer it is to being completely airtight, the better.

Should you put a fan on seedlings?

A fan can assist in ensuring adequate air circulation around seedlings. Don’t direct the fan directly at your seedlings; instead, aim it to generate a gently breeze for them. Maintain the fan’s operation 24 hours a day. In addition to assisting in the prevention of illness, the continual air flow will aid in the development of stronger, more enduring seedlings.

Can I vent grow tent into attic?

Experiment with venting the grow tent into the attic or chimney. Many farmers believe it to be a viable choice for venting their plants. However, there is a possibility that some significant complications will arise. First and foremost, there is the question of whether or not to use the term “issue” in the context of this document. First and foremost, there’s the fragrance. When you vent your grow tent into your attic, you will avoid the accumulation of humidity and heat.

What causes high humidity in grow tent?

When the temperature within your grow tent is greater, more water vapor will be able to be held in the air. The heat generated within a grow tent allows water to travel more quickly through the air, resulting in increased relative humidity.

Is negative air pressure bad for Grow tent?

It provides a steady atmosphere for your plants while also reducing the possibility of mold or mildew development on them. Negative pressure in your grow tent is a certain approach to provide the optimal and most stable environment for your plants to develop, even if there are reasons to employ positive pressure or equalized pressure in your grow tent.

Do light leaks matter during veg?

Plants emit oxygen when the lights are turned off. Furthermore, the transition from an 18-hour vegetative cycle to a 12-hour blooming cycle indicates to the plants that it is time to flower. Any light leaks that occur after the switch have the potential to disrupt this and force the plants back into vegetative development. In some plant species, you may even encounter genetic anomalies that are not present in other species.

What size fan for 2×4 grow tent?

We recommend the 4 inch fan from AC Infinity for anything that requires less than 205 cfm.

We suggest their 6 inch fan for anything that requires less than 402 cfm. We suggest their 8-inch fan for anything that requires less than 807 cfm. If your tent’s airflow requirements exceed 807 cfm, you’ll need to install many fans in it.

Do grow tents keep the smell in?

Simply said, grow tents will not be sufficient to keep smells at bay. The materials and components that make up a grow tent system (reflective mylar, tent canvas, inline duct fan, ducting tubes, and so on) do not meet the requirements for being smell proof.

Do you need AC for grow tent?

If the temperature range in your grow room is consistently between 60 and 85 degrees Fahrenheit, you can get by with simply a dehumidifier and a fan to keep things running smoothly. If your grow room is enclosed, you’ll need to install an air conditioner.

What is the best way to cool a grow room?
