What Size Inline Fan For 4X4 Tent

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 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.

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.

What Size Fan do I Need for 4×4 Grow Tent? Guide for Cannabis Growers

The volume of your space may be calculated by multiplying the length, breadth, and height of your room. Consider the following example: if you had a grow tent with dimensions of 4′ x 4′ x 7′, the volume would be (4x4x7) = 112 cu./ft. Converting Volume to CFM In two minutes, your exhaust fan should be able to exhaust the equivalent of the volume of your growth environment, or one minute if you are experiencing problems with high temperatures. Assuming there are no problems with heat, the growth environment volume from our example is 112 cu./ft., which implies we need to exhaust 112cu.ft.

  • As a result, I know that I require a minimum of a 56 CFM fan.
  • If you utilize air-cooled lights in your grow room, though, things are a little different.
  • The same is true for other heat-generating equipment such as motors and other such devices.
  • Suppose you have four 1000W fans, each with a 200CFM capacity, and the typical calculations indicate that each fan has a capacity of 200CFM, then the total will be — Fan Size= (200 CFM + (200 40%))= 280 CFM What is the significance of air circulation?
  • When compared to growing outside, this might provide some difficulties.
  • A consistent supply of fresh air combined with a little wind (not too much, not too little) helps cannabis develop more quickly and even protects plants from some pests and molds, according to research.
  • In the majority of situations, a 4 inch carbon filter will be more than sufficient for a 44 camper.

It is possible that you will be using an HPS (High-Pressure Sodium) lamp, in which case you would need a bigger 6-inch carbon filter and a higher CFM fan.

It’s also critical to choose the proper fan size for your carbon filter in order for it to work at optimal performance.

This implies that it does not require any maintenance in order to continue to function at its maximum capacity.

In addition, the fan is fluted on both sides, which allows it to accept ducting from both directions. This also implies that it is intended for use in regions where there should be extensive lines of ducting in order to increase air flow.

Hydrofarm Active Air Inline Fans

Active Air is yet another well-known name when it comes to inline fans for hydroponics. They have models in four different sizes: four inches, six inches, eight inches, ten inches, and twelve inches. This brand is well-known for its longevity, simplicity, and outstanding design. The fans operate silently, are covered with a ceramic coating to prevent rust and corrosion of the metal components, and come with all of the mounting brackets and hardware necessary to install the fans. Growing a huge amount of cannabis and want to have a professional-grade grow operation requires the purchase of high-quality equipment.

Due to the fact that Active Air’s fans do not come with a built-in speed adjustment, you will need to purchase one separately.

What Size Fan for a 4×4 Grow Tent

Approximately what size fan should I use for a 4×4 grow tent? For a 44 grow tent, the size of the fan you’ll need will vary on a number of different things. There are other factors to consider, like the type of lighting you’re using and whether you’re growing in soil or a hydroponic system. In most circumstances, a 6″ inline exhaust fan will be sufficient for most 4’4 grow tents due to its high capacity. However, if you want to use a HID light fixture that generates a significant amount of heat, you may need to upgrade to an 8-inch fan.

4×4 Grow Tent CFM

The majority of 44 grow tents require an exhaust fan that can move air at a rate of 200 to 400 cubic feet per minute to function well (CFM)

4×4 Grow Tent Turnover Rate

An exhaust fan should rotate the air in a 4×4 grow tent 1 to 5 times per minute, depending on the temperature.

When purchasing an exhaust fan, it is important to ensure that it is appropriate for the size of your grow tent. If you have more than a few plants in your grow tent, choose an exhaust fan that can move at least 200 cubic feet per minute (CFM) of airflow (higher CFM ratings are better).

What Size Fan Do I Need For My Grow Tent? (With Handy Table For Common Sizes)

First and foremost, the bad news. It’s possible that you’ll have to conduct some math. The good news is that It’s a simple piece of mathematics. And we’ll take you step by step through the process. In addition, we’ll provide you with a useful table that lists the most typical grow tent sizes and configurations. Chances are you will be able to find your information in the table and will not have to perform any calculations.

What Size Fan Do I Need For My Grow Tent?

It is not the size of the fan that is crucial. It refers to the capacity of the fan. First and foremost, you must determine the amount of capacity you require. The capacity, in turn, dictates the size of the fan. For the majority of home gardeners, a 4 or 6 inch fan would suffice. How do we determine the amount of fan capacity you require for your grow tent’s fan? By following the steps in the computation we’ll go through later. Alternatively, you might scroll down to our table and see whether your tent size is listed there as an option.

Calculating Base Fan Requirement For Your Grow Tent

Obtaining the overall volume of your grow tent is the first piece of information you’ll need. To obtain this, simply multiply the width by the length by the height (width times length times height). For the sake of this computation, we are using feet rather than cubic feet per minute since fan capacity are measured in cubic feet per minute in the United States. It makes no difference whether or not you utilize meters in your calculations. Consider the following scenario: you have a 5 by 5 foot grow tent with a height of 78 inches, or 6.5 feet.

  • The total volume is equal to 5 x 6.5 = 162.5 ft3.
  • The capacity of a fan is measured in cubic feet per minute (cfm), which is an abbreviation for cubic feet per minute.
  • For the most part, we recommend that you strive to refill the air in the tent once per minute.
  • Using this formula, divide the entire grow tent volume by two or three to obtain the base fan capacity you want.
  • Not so fast, my friend.
  • If you simply have one fan extracting air and nothing else, the capacity we offer is the minimum amount required.
  • In addition, there are variables that raise the capacity requirements.

Adjusting For Ducting, Filters, Lights, Etc.

Components such as ducting and filters all contribute to a reduction in the capacity of your fan. You must take this into consideration in your calculations and purchase a fan with greater power to compensate for the drop in airflow. Other components, such as lighting, can enhance your cooling requirements. You’ll need to build in some extra capacity to accommodate them.

If your tent is going to be in a hot environment, you should also include some extra capacity. Here are some of the most typical components and considerations to consider, as well as the impact of the additional capacity you’ll wish to add, expressed as a % increase in capacity.

  • Lights: a 10% rise for each additional grow light
  • Filters: a 25% increase for each additional filter
  • Ducting: a 1% increase for each additional foot of ducting
  • Bending of ducting: 30 percent for every 90-degree bend (15 percent for every 45-degree bend)
  • External heat: If your grow tent is located in a warmer area (e.g., the attic or a sunny room) and/or is not adequately insulated from the external environment, the temperature will rise by 10%.

Add together all of the percentage increases to obtain the overall % increase. Consider the following scenario: we have a single grow lamp, one filter, and 6 feet of ducting with one 90-degree curve. However, the tent is not situated in an exceptionally hot environment. Growth lights add 10% to the total percentage increase, which is 25 percent to the filter and 36 percent to the ducting and bend. The total percentage increase is 71 percent. Then you’ll want to convert this percentage to a decimal and multiply it by one hundred.

  1. A 44 percent rise would result in a 1.44 percent gain.
  2. As a result, a 125 percent rise would result in a 2.25 percent increase.
  3. As a result, 5 percent would be 1.05 percent (and not 1.5, which is a 50 percent increase).
  4. In our example, that was 162.5 cubic feet per minute.
  5. In our case, the required capacity is 162.5 cfm multiplied by 1.71 to equal 277.875 cfm.
  6. However, it is typically a good idea to get a fan that has around 25% greater capacity than you actually require.

Get A Fan With More Capacity Than Required

We strongly advise you to get a fan with a larger capacity than you require. Running fans at full capacity puts greater strain on them, which means they will not last as long as they should. It also causes them to become louder. When you run a fan at a lower speed than its maximum speed, it will last longer and operate more silently. It also provides the ability to expand capacity in the event that your cooling requirements develop in the future. Nothing can be predicted; a heat wave, for instance, may occur.

Adding 25 percent to our previous example works in the same way as before: increase the capacity by 1.25 times the percentage.

Make a rounding error and purchase the next largest capacity fan of the type you desire.

It has a capacity of 402 cubic feet per minute.

What Is A Good Fan To Get?

There are many various types of fans available on the market, and the most of them will perform admirably. In general, the more money you spend, the higher the quality of the product or service you receive. This typically indicates that the fan operates at a lower noise level, is more efficient (has a larger capacity per watts consumed), and has a longer lifespan. Our favorite fans are the AC Infinity Cloudline fans. They are neither the most affordable nor the greatest quality. However, they are the most cost-effective option.

The 4 inch fan has a capacity of 205 cfm, the 6 inch has a capacity of 402 cfm, and the 8 inch has a capacity of 807 cfm. In huge tents, you may require more capacity than even the largest fans are capable of providing. This would necessitate the purchase of a number of fans.

Table Of Fan Requirements For Common Grow Tent Sizes

The fan power (in cubic feet per minute) required for various grow tent sizes is shown in the following table. It is not an issue if the height of your tent is somewhat different from the standard height. The capacity that has been provided will still be adequate for your needs. In the same way, if you have a few additional feet of ducting (or a few extra feet less), you may still utilize the closest circumstance in the table to get the job done. Because you should be purchasing a fan that can handle around 25% more airflow than your requirements, you should have some wiggle space if you find yourself in need of a little extra power later on.

  • That implies one light for everything up to and including the 55, two lights for the 48 and 510, and four lights for the two biggest sizes, respectively.
  • That means the cfm value you are given is your final number, and it is this number that you should search for in a fan while shopping.
  • We suggest their 6 inch fan for anything that requires less than 402 cfm.
  • If your tent’s airflow requirements exceed 807 cfm, you’ll need to install many fans in it.

Do I Need An Intake Fan?

In most cases, an intake fan will not be required for tiny tents. If you have a sufficient number of intake vents or if they are of sufficient size, having only intake vents may be sufficient. Generally speaking, opening intakes should be three to four times the total size of the outtake vents, according to the rule of thumb (s). You might have one enormous intake aperture or three smaller ones that are each as large as the outflow opening, depending on your needs and preferences. If your tent does not have enough, or openings that are large enough, you will need an intake fan to keep the air flowing.

It has the potential to have around 25% less power.

It goes without saying that any ducting and bends in the ducting that are linked to the intake fan should be taken into consideration as well.

In the case of 5 feet of ducting with one 90-degree bend linked to the intake fan, you need to increase its capacity by 30% (25 percent for the bend and 5 percent for the ducting length), therefore you multiply by 1.3 to get the required increase in capacity.

What Size Carbon Filter Do I Need?

When purchasing a carbon filter, there are basically just two considerations to keep in mind. The first is that the flange size must correspond to the fan size. If you purchase a 4 inch fan, be certain that you also get a 4 inch filter. Second, ensure that the filter’s capacity (also measured in cubic feet per minute) is equal to or greater than the fan’s capacity.

It is recommended that you get filters from the same manufacturer as your fans. For example, if you choose the AC Infinity fans that we propose, they will come with matching filters as well.

Where To Place Fans And Filters

You have a great deal of latitude in this situation. The first option you must make is whether to place both the fan and the filter inside or outside of the tent, depending on your preference. It is also possible to have one inside and one outdoors. Inside is normally less difficult, but it may not be a choice if you do not have the necessary room. If you’re thinking about placing your grow tent outside, check out ” Carbon Filter Outside Grow Tent “. The fan and filter should be placed at the very top of the tent if they are being used within the enclosure.

In order to pull in colder air, the intake vents (or fans, if you want to use them) should be situated toward the bottom of the enclosure.

Fan Size For Grow Tent: Final Thoughts

Calculating the proper fan size for your grow tent may appear to be a difficult task, but it does not have to be. In following the guidelines we provided above, you will end up with a fan that is capable of successfully removing any surplus heat from your tent, regardless of whether you have a large grow tent or a little grow tent setup. Most likely, the size of your tent was already included in our table, and you were able to avoid having to perform the calculation. It wasn’t that tough, even if you had to perform the arithmetic (or even if you simply ran through it in your head), since it wasn’t that complicated.
