What Size Exhaust Fan For 4X4 Grow Tent

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.

1. 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?
2. When compared to growing outside, this might provide some difficulties.
3. 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.
4. In the majority of situations, a 4 inch carbon filter will be more than sufficient for a 44 camper.
5. 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.
6. It’s also critical to choose the proper fan size for your carbon filter in order for it to work at optimal performance.
7. iPower 4 Inch 190 CFM Duct Inline Fan with Remote Control This inline fan provides good and dependable service as a result of the superior technology with which it was outfitted.
8. When the fan is turned on, it produces no noise or vibration because of the way it is designed specifically for this purpose.
9. 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.

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).

So, for a 4×4 grow tent with an area of around 106 cubic feet, a grow tent fan (inline fan) with a capacity of 215cfm would be sufficient.

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 makes incredible 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 better than the competition? This fan is equipped with a programmable controller, which allows the fan to turn on in response to a variety of different conditions. For example, you can program the fan to turn on when the humidity reaches a certain level.

• You can also set a timer and receive alarm notifications.
• When my AC Infinity T4 was running at full power, I was pleasantly surprised at how quiet it was.
• This results in the fan motors becoming noisy.
• Quiet Inline Duct Fans With Temperature and Humidity Control – CLOUDLINE SERIES These fans are priced similarly to other fans without the technical features, so 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 if 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.

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 many watts do I need for a 4×4 grow tent?

In a three-quarter tent, you should aim for 350 watts. Amazon led lights are something I would avoid. Generally speaking, they are either very inexpensive and of poor quality, or very expensive and of poor quality. For those searching for an already-assembled light, 700 will be a challenging range.

What size exhaust fan for 3×3 grow tent?

In a 3/3 tent, you should aim for 350 watts of power. I would steer clear of Amazon’s LED lights. They are either very inexpensive and of poor quality, or very expensive and of poor quality. If you are searching for a light that is ready to go, 700 is going to be difficult to come by.

Do you need AC for Grow Tent?

Portable Air Conditioning for Grow Tents You may also purchase an air conditioner for your grow tent instead of a duct system if you choose not to use one. It is convenient to have a portable air conditioner since it can be moved about the room as needed. The use of an air conditioner is handy, but it has the potential to pollute the air with carbon dioxide.

Are tower fans good for Grow Tents?

Tower fans may offer circulation above and below your plants at the same time, allowing for more efficient plant growth.

Many types oscillate, allowing them to completely cover the tent. Even while they are more expensive than some of the more affordable tent fan alternatives discussed above, if they can cover double the area, you will require fewer fans, which can help to offset the expense.

Should I leave my fan on when lights are off?

During daylight hours, both exhaust and oscillation fans should be functioning, as they should always be. If you have 2-3 oscillating fans, one intake fan, and one exhaust fan, you should leave the oscillating fans running throughout the whole dark time. Also, switch off the other fans one hour after the light is turned off.

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?

The terrible news is first and foremost. Some calculations may be required. The good news is that it is still possible to participate. Simple arithmetic is required. And we’ll take you step by step through the process.” As an added bonus, a useful table with common grow tent sizes and configurations will be provided. Many times, the table has the information you want, and you will not need to perform any calculations.

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.

1. The total volume is equal to 5 x 6.5 = 162.5 ft3.
2. The capacity of a fan is measured in cubic feet per minute (cfm), which is an abbreviation for cubic feet per minute.
3. For the most part, we recommend that you strive to refill the air in the tent once per minute.
4. Using this formula, divide the entire grow tent volume by two or three to obtain the base fan capacity you want.
5. Not so fast, my friend.
6. If you simply have one fan extracting air and nothing else, the capacity we offer is the minimum amount required.
7. 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.

• All of the components of your fan, such as ducting and filters, lower its overall capacity. In order to compensate for this reduction, you must factor it into your calculations and purchase a fan with more power. Your cooling requirements are increased by other components, such as light fixtures. For this reason, you will need to add some more capacity. Adding more capacity to your tent if it will be used in a hot climate is a good idea. As a guide, below are some of the most typical components and elements to consider, as well as the effect that adding greater capacity will have, expressed as a percentage increase.

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.

• A 44 percent rise would result in a 1.44 percent gain.
• As a result, a 125 percent rise would result in a 2.25 percent increase.
• As a result, 5 percent would be 1.05 percent (and not 1.5, which is a 50 percent increase).
• In our example, that was 162.5 cubic feet per minute.
• In our case, the required capacity is 162.5 cfm multiplied by 1.71 to equal 277.875 cfm.
• 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.

1. 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.
2. 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.
3. We suggest their 6 inch fan for anything that requires less than 402 cfm.
4. 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.

How to Calculate Required CFM for a Grow Tent

When it comes to ventilation a grow tent, it’s critical to understand how much air has to be moved in order to offer a suitable amount of fresh air. Due to the fact that it takes up the whole area, you can safely assume that the volume of your grow tent is equal to the amount of air that has to be exchanged. When you are filling the area with accessories, the calculations get a little more complicated. So, using our full-grow tent ventilation instructions, you can learn how to calculate the CFM you require.

The Formula

Determine its cubic foot capacity by multiplying its length by the width and height of the object in question. Convert measurements between different units of measurement as needed. This will equal the volume of your area, and the needed airflow will be equal to this value in cubic feet per minute, or CFM, as shown in the table. The following is an example of the formula: As an example, a 48″x36″x72″ grow tent translated to feet would be a grow tent measuring 4’x3’x6′ in size. When the measurements are added together, the result is 72 ft3 of space.

Grow Tent Accessories

In order to boost your base CFM, you must multiply it by the efficiency percentages of your accessories. In your grow environment, adding components such as ducting and carbon filters may lower fan performance, which will alter how hard your fan has work to get the desired results. When it comes to ducting, the quantity 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.

1. Smoothing out any creases can also help to improve the operation of the fan and the flow of air.
2. These considerations increase your necessary CFM, which necessitates the use of a high-capacity fan in order to move the predicted airflow.
3. Grow light heat multiplied by (base CFM multiplied by component components) = Required CFM For example, our 4’x3’x6′ grow tent has a CFM of 72 as a starting point.
4. Adding a carbon filter (60 percent), ducting (20 percent), and a silencer (20 percent) to our ventilation system increases the airflow rate to 166 cubic feet per minute.
5. Keep in mind that these percentages are not set in stone and may change at any time.

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.

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. Your carbon filter will also operate better if it is installed at the greatest possible elevation.

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.

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 quantity 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.

Look for inline duct fans that are powered by direct current (DC) fan motors, which are the quietest as compared to alternating current (AC) fan motors. 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.
