What Size Inline Fan For 2X4 Grow Tent

How Many Cfm For A 2X4 Grow Tent

200 CFM is sufficient. You’ll need at least 150 people for your tent, depending on its size.

What size fan for 2×4 grow tent?

We recommend the 4 inch fan from AC Infinity for anything with a flow rate 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.

How do I calculate CFM for Grow Tent?

To calculate the CFM of your fan, multiply the size of the grow area by the number of blades. To calculate the overall volume of the tent, multiply the height, breadth, and length of the tent together. The entire volume of the tent should be the same as the cubic feet per minute (CFM) of your air conditioner. It is important to note that most fans are measured in Cubic Feet Per Minute (CFPM) (CFM).

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.

How much ventilation do you need for a grow tent?

To figure out how many cubic feet per minute (CFM) you’ll need to adequately ventilate your grow room, use the following formula: / (Grow Space Width X Length X Height) = Recommended CFM (cubic feet per minute). The length and course of the ducting have an impact on the CFM performance of a fan. If you are utilizing a carbon filter, this will significantly impair the performance of your fan.

How often should I exhaust my grow room?

Exhaust fans are often rated in cubic feet per minute (CFM), which refers to the volume of air that is pushed. A ventilation system that can exchange the air in your grow room AT LEAST once every three minutes will be ideal for your needs.

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.

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.

Do you need fresh air in a sealed grow room?

There is no air removed from or pulled into the grow-space from outside the enclosed grow-space. Although air temperature, relative humidity, and CO2 levels are important factors to consider when growing, they are not the only ones that should be considered. Generally speaking, odors are not an issue in the room because it is airtight.

What size carbon filter for 5×5 grow tent?

How long should a fan be on in a grow room?

It is recommended that your grow room’s extractor fan system replenish the air in your grow room once per minute, or at the very least every three to five minutes.

What size exhaust fan for 5×5 grow tent?

Another 6 or 8-inch fan should be used for tent exhaust. This fan should be mounted again outside the tent, this time near to the outside air opening. If you are concerned about stinking air blowing outside the tent, you may hang the necessary charcoal filter inside the tent. This will prevent this from happening.

How many CFM do I need for a 12×12 room?

It is recommended that you have at least 1 CFM per square foot of room area as a general guideline. To find out how much square footage your bathroom has, multiply the length by the breadth of the space.

Can I leave my 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 everyone and everything in the room as a result of this.

How many fans 5×5 grow tent?

Because a 55 grow tent may only accommodate one or two fans, make sure that they are carefully placed throughout the tent.

What size extractor fan do I need for Grow Tent?

Grow room capacity (cubic feet), carbon filter factor (+25 percent), insulation factor (20 percent), ducting (+10 percent for 10 feet) and light factor (+10 percent for 1000W) are all factors to consider when determining the size of your extractor fan for your grow room or tent. You’ll be given the fan size in cubic feet per minute (CFM).

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. In addition, switch off the other fans one hour after the light is turned off.

What size carbon filter for 4×4 grow tent?

What size carbon filter do you recommend for a 4×4 tent? In the majority of circumstances, a 4-inch carbon filter will be sufficient for a 44 camping tent. The fact that a 44 tent has a relatively limited interior volume means that a 4-inch carbon filter should be able to effectively remove any smells from the air before they are expelled from the tent.

How many CFM do I need for 1000 square feet?

50 CFM (cubic feet per minute) The total floor space of the house (square feet) 1,000 square feet per minute of continuous ventilation 50 CFM (cubic feet per minute) 2,000 square feet of floor space 100 CFM (cubic feet per minute) 3,000 square feet is a large area. 150 cubic feet per minute

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.

What size grow tent do I need for 4 plants?

A rectangular tent shape is the most effective for four plants, and the most typical size is a 44.

This provides each plant with around 4 square feet of growth room (or a 22 of the total area). It is really a little less than that, because you want to leave some space between the plants to allow for air circulation. However, this still allows for quite big plants.

How many CFM do I need for 500 square feet?

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

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

Selecting the proper grow tent fan size and power:

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

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

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

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

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

What size fan is needed for other grow tent sizes?

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

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

Grow tent fan placement:

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

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

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

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

Grow tent fan setup:

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

Passive or Active Air Flow For Your Grow Tent?

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

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

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

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

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

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

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

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

Other Inline Fan Installation Notes:

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

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

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

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

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

Which Grow Tent Fans I Recommend:

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

  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.

I developed numerous useful lists and tips to assist you in completing your home improvement project the right way, in addition to determining the proper fan size for your needs. The following are some other articles I strongly recommend: Choosing the Proper Size Grow Tent, This Year’s Best LED Grow Light List, and Understanding Grow Light PAR PPFD and Wattage, among others.

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.

First time grower with 4’x2’x5′ tent needs ventilation help

You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. Greetings, everyone! I’m getting ready to start my first grow here very soon, and while I’ve gotten a lot of things down pat, one area that I haven’t been able to figure out is ventilation, which has been a major source of frustration. For a tent that measures 4x2x5 feet and with LED lighting, what size fan would I require?

  • I’m not really clear what CFM is or how to estimate how many CFM are required for a certain area of a given size.
  • Any assistance would be much appreciated!
  • Budget is ultimately what determines the final outcome.
  • It’s 4x2x5 like you mentioned.
  • 4 times 2 times 5 equals 40 Your tent has a volume of 40 cubic feet.
  • Whenever you purchase a fan, it will have a CFM rating.
  • It informs you how much air it can move in a minute by displaying the capacity.

As a result, for your tent, I would recommend a fan with a minimum capacity of 40cfm.

That is something you should take into mind.

The sort of fan you employ will also make a significant difference.

I do use them, but only to blow air into the cabinet, not to accomplish anything else.

Generally speaking, there are three categories of supporters.

They will underperform and will eventually burn out as a result.

CENTRIFIGAL: These are the fans that you wish to use for your project.

They will last for a long time and perform admirably.

MIXFLOW: I’d never heard of them before, but they’re a hybrid of axial and centrifugal flow.

If you can’t afford a centrifigal fan, it’s probably best to start with one of these instead.

Most of the time, an inline fan is necessary, especially if a filter is being utilized.

It’s in the hundreds of thousands of dollars.

Your tent has a volume of 40 cubic feet, and if you plan on employing a carbon filter, I would recommend investing in a good fan with a flow rate of at least 80cfm.

Once a minute is a pretty broad rule of thumb to follow.

Especially if there is going to be a lot of heat involved.

It can still generate a little amount of heat, depending on the lighting conditions.

Allow me to describe my set-up to you.

My fan is a mixflow, and it has a capacity of around 120cfm.

There is no ducting.

I’m using a mars II led with 700w of power.

I have a few of wireless thermometers that I use to double-check the readings.

Which is excessive, especially considering the fact that it is summer in my region of the world at the time.

However, if there isn’t enough ventilation, the heat will build up and eventually reach the plants themselves.

Because it is so chilly, I’ve seen several individuals who have had to turn on heaters in their tents.

As a result, that might be another factor to consider.

You must change the air to ensure that your plants receive a consistent supply of CO2, with one change per minute being ideal; however, if you are experiencing heat difficulties, you may need to change the air many times per minute.

If this is the case, you will want additional ventilation.

I hope I’ve provided you with some valuable information here.

I’m going to stop talking now.

Perhaps someone else can provide some alternate advise.

Paul, I simply wanted to point out that in order for a fan to be able to remove air at the rate specified by the manufacturer, fresh air must be drawn in at the same rate.

The actual Cfm will be decided by how quickly the inletslet air in.

You refer to it as rambling.

A 120cfm fan would be sufficient for dissipating the odor, or should I look for something a bit larger?

It is also my intention to construct my own carbon filter in the manner oforI like the latter since it is not a monstrosity, and if at all feasible, I would want to keep my filter in my tent.

For my soil and nutrients, I’m looking at $600 maximum, plus $60 for nutes.

What’s the difference between up and down?

Doctor Earth |

With free shipping through Amazon Prime, the tent costs $80.

Indecisive whether I want to spend the money on smart pots or simply use the free 2 gallon buckets I can acquire from work.

The lights will cost me $309 since I will have to either make two separate transactions (which is what I’m doing) or wait an extra week to get started while the second CC is being delivered.

So, as of right now, I have $80 in my bank account.

What more would I require that I haven’t considered, what kind of fans would be the most appropriate for that $80 while still allowing me to purchase the goods I haven’t considered?

I guess I’ll attempt to use some computer fans as input fans if it’s feasible.

Paul, I simply wanted to point out that in order for a fan to be able to remove air at the rate specified by the manufacturer, fresh air must be drawn in at the same rate.

The actual Cfm will be decided by how quickly the inletslet air in.

Yes, you are quite correct.

It will continue to function as long as your air intake hole/flap is the same size or larger than your exhaust hole/flap, which is preferred.

However, it will place a slight additional load on the fan.

Are you ready to go yet?

I’ve never attempted to build a carbon scrubber, so I can’t provide any advise or expertise on the subject.

Filter manufacturers utilize vibrating machines to carefully pack the carbon and ensure that every gap is properly filled.

There are various other ventilation systems that you may utilize, but I won’t go through them all here.

It is true that employing intake fans will alleviate some of the strain on your exhaust fan, but if you are using fans that blow more air into the tent than your exhaust fan can suck out of the tent, you will be in what is known as a positive pressure condition.

A lot of individuals employ a design known as passive intake, active exhaust, which means they just use an exhaust and do not have any fans pumping air into the car; instead, they often have a large hole someplace for air to enter through.

A negative pressure environment is what this is referred to as.

For the time being, I will not provide any off-site links because I am not completely certain of the rules, but you can look up the websites for some of these companies.

When it comes to the soil and nutrients, I’m not acquainted with the brand, but I did some research and discovered that it’s jam-packed with nutrients that your plants would like, but I don’t advocate using it at first.

Seedlings do not require any nutrients, and if you use that nutrient-dense soil, it may restrict their growth and, in some cases, cause them to die.

As for the nutes, you won’t need them straight immediately, as previously said.

As a result, you should be able to go a few weeks without having to purchase any fertilizer.

I’m not sure how dolomite lime and oyster shells are going to be utilized.

It’s beneficial to have them on hand.

When it comes to smart pots, I have no personal experience with them.

It is all up to you.

It appears like you are on the right track with your setup.

If you haven’t previously done so, there is a great place to go for information if you haven’t before.

Here’s the URL to the page.

I hope I didn’t come off as proposing the use of a ventilation fan.

My setup is still in progress, but I’ve received two $300 credit cards with 0% interest in the mail.

When I get my first mars hydro 300w old model, a tent, seeds, soil, and a fan, and after I’ve figured out what I’m doing, I’ll buy my second mars hydro 300w old model.

I was planning on doing two, but someone informed me that the third light would result in a yield boost of between 25 and 33% over the first two.

Is that also a reasonable yield increase as a result of the additional light?

Worst case scenario, I go with a 120 off Amazon, where I can buy one for 20-30 dollars, with the goal that it will not burn out in one grow and that I will be able to upgrade later.

According to my research, automatic plants do not like to be transplanted, and many of the really large Fast and Vast plants I’ve seen in grow journals appear to have been planted directly into the soil.

I actually just discovered it today, but after glancing through it, I saw that the most of the lighting topics were about HIDs, with little coverage of LEDs and no autoflower section, though I didn’t examine at all attentively, just scanned through all of the posts.

Are you sure you’ll be able to fit those three lights into that small space?

Even with cool running lights, they could generate a significant amount of heat in such a small space with so many of them so close together.

It’s just a wild guess.

I was unable to provide you with a percentage.


I tried the inexpensive tiny axial fan, but it didn’t function well, was noisy, and was made of plastic, which finally caused the motor to melt through the plastic.

So it had to have been under a lot of pressure.

I’ve had it for about 3 months and it appears to be functioning quite well, pulling a good volume of air.

In the long run, it would have been less expensive.

In one of these forums, I recently came across a wise saying: ‘If you purchase cheap, you buy twice.’ However, I am aware that you are on a tight budget.

I was always concerned about being seen and didn’t want a fan that made a lot of noise.

I wouldn’t miss having an intake fan at all.

I just use it to relieve some of the tension from my exhaustion.

I would love to have total control over them, including when they blossom and how big they are.

What I don’t know is whether they can be transplanted successfully or not.

As a result, it starts off with only standard dirt, but as the roots grow, they will spread out into the excellent soil.

I had been browsing at picture plants for a long when I came across Fast and Vast, which has some insane yields and potency, so I decided to give it a shot.

The promise of producing high-THC bud in a shorter amount of time was a significant lure, but I’ll definitely experiment with some conventional plants sooner or later. That is, in fact, exactly what I intended! I just reworded it a lot better, thank you for your assistance.

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 purchase a fan with speed controls and a CFM rating that is 25 percent higher than your minimum requirement will allow you to run the fan at lower speeds without sacrificing 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.

Grow Room Fan Size Calculator with Size-wise CFM

Grow Room Fan Size Calculator with Size-Wise Results»Home»Environment»Grow Room Fan Size Calculator with Size-Wise Results CFM31702Views0 If the ventilation is too low or too high, it is the same as having dead(almost) grow plants. And the overall ventilation of your grow system is mostly determined by the size of the intake and exhaust fans that you use. So, how do you determine the appropriate fan size for a grow room? To calculate the size of your grow room or tent’s extractor fan, multiply the volume of your grow room (in cubic feet), the carbon filter factor (+25 percent), the insulation factor (20 percent), the length of ducting (plus 10 percent for every 10 feet), and the light factor (plus 10 percent for every 1000W).

  1. If you want to figure out what size intake fan for grow room to utilize, simply subtract 15-20 percent from the size of the extractor fan.
  2. Some of you may eventually raise an eyebrow and wonder, “What on earth do these ‘factors’ mean?”.
  3. Take it easy for a while, dear grower.

Factors to Consider in Calculating Grow Room Fan Size

First and foremost, let’s define what these parameters are, how they influence the calculation of grow room fan size, and what precise proportion they must contribute to the computation.

Factor 1: The Volume of The Room/Tent

To begin, determine how much space your fans will have to contend with, also known as the active grow space. Or to put it another way, that is the area illuminated by your grow lights. And, in order to keep things simple, let’s suppose that your fans will be able to completely replenish the air in the room in one minute (explained in the next section). a general rule of thumb Simply take the measurements of your tent (length, breadth, and height) and multiply them together to obtain the total volume.

Without taking into consideration any other considerations, this figure represents the fan CFM that you require.

Let’s say you’re working with a tent that measures 10x10x7 ft. For example: Fan Size= (10 feet by 10 feet by 7 feet)/1 Minute = 700 CFM; Fan Size = (10 feet by 10 feet by 7 feet)/1 Minute = 700 CFM;

Factor 2: Time of Complete Air Replacement

When determining the fan size required for your grow room or tent, you must first determine the volume of air that needs to be ventilated each minute of the day. Because, as you may be aware, the size unit (CFM) indicates the amount of air that the fan can move in a minute. a general rule of thumb Calculate the volume of your grow area (length x breadth x height) and divide it by the number of minutes it takes to completely exhaust all of the air in your grow space. According to this example, if the room’s dimensions are 10 feet(L) x 10 feet(W) x 7 feet(H), the total volume will be 700 cubic feet in total.

Factor 3: Presence of Carbon Filter

It is necessary to determine the volume of air that needs to be ventilated in each minute when determining the fan size needed for your grow room or tent. Remember that a fan’s capacity (measured in cubic feet per minute) is measured in cubic feet per minute (CFM). As a general guideline, Make a calculation based on the volume of your grow area (length x breadth x height) and divide the result by the number of minutes it takes to completely exhaust the air in it. According to this example, if the room’s dimensions are 10 feet(L) x 10 feet(W) x 7 feet(H), the total volume will be 700 cubic feet in size.

Factor 4: Insulation of the Room

If you are growing in a well-insulated area that does not experience a great deal of heat exchange with the surrounding environment, you do not need to take this element into consideration. Theattic, basement, upstairs, south-facing bedroom, and other such spaces with less insulation and more exposure to the sun are examples of such regions that need to be taken into mind. In any of these scenarios, the temperature will be either higher or lower than the temperature that you are required to maintain in your grow room.

If the unit is located in a chilly environment, such as a basement, the needed CFM should be reduced by 15%.

Factor 5: The Ductwork Curves and Length

It should go without saying that ducting bends and length will reduce the air extraction capability of the fans in the system. Depending on the size of your grow room and the quantity of plants in it, there are three possible ducting configurations:

  1. Ducting that is as short as possible or without bends
  2. The following types of ductingruns are available: medium ductingruns (5-10 feet) with 2-3 bends
  3. Long ductingruns (10-20 feet) with 3-6 bends

As a general rule of thumb The fan CFM will increase by 5 percent for every 5 feet of ducting that is installed. The CFM will increase by 20% for every 90-degree angle in the ducting.

If you have a 200CFM starting fan size, you need do the following: Consider the following: fan size considering ducting(15′)=(200 CFM + (20015 percent))= 230 CFMF Consider the following: 320 CFM (assuming bends (3) = 200 CFM plus (200-60 percent)) = 200 CFM

Factor 6: Lights and Other Heat Sources

As you are aware, the two most evident heat sources in a lamp are the lights and the pumps. If you utilize air-cooled lights in your grow room, though, things are a little different. However, if they are not air-cooled, you must account for each of them when estimating the size of your expected fan. The same is true for other heat-generating equipment such as motors and other such devices. As a general rule of thumb For every 1000W of bulb power, increase the fan cfm need by approximately 10%.

Grow Room Fan Size Calculator(ExtractorIntake Fan)

To complete this section of thegrow room fan size guide, we’ll use a test case of a grow space, imply certain basic circumstances, and figure out the ultimate size of bothgrow room ventilationfans of both extract and intake. Consider the following scenario: we have an 8x8x7 grow tent in your basement, along with an inline carbon filter that is connected to a 4′′ duct system. There are 15 plants to grow in the space since it is large enough for ScrOG type training (according to our size guide).

In addition, except from the light, there are no other significant sources of heat.

Extractor Fan

Let’s start with the formula for the grow room extractor and intake fan calculator:-

Step 1: Calculate the Space Volume

Let’s start with the formula for the grow room extractor and intake fan calculator:

Step 2: Calculate The Air Replacement Time

For the sake of argument, let us suppose that whichever fan we end up with will be able to replenish the whole volume of air in the tent/room in less than one minute. The computation becomes less complicated as a result of this. Fan Size = Volume x Number of Minutes to Empty 448 cubic feet per minute = 448 cubic feet per minute of air (Cubic Feet Per Minute)

Step 3: Calculate Carbon Filter Allowance

As previously stated, we have a 4″ carbon filter installed in our setup, which is connected to the ducting system. Furthermore, the precise pace at which it will impair fan efficiency is 25 percent. As a result, the fan size is 448 CFM plus (448 25 percent) = 560 CFM.

Step 4: Calculate the Insulation

The amount of insulation in the grow room/tent has a significant impact on the environment in which the plants develop. Consider the fact that we have a grow setup in the basement, which is significantly colder than the other room where it was originally planned to be. As a result, we’ll take a 15% reduction in the needed fan size for the space into consideration. Fan Size= 560 CFM – (560 15%)= 476 CFM Fan Size= 560 CFM – (560 15%)= 476 CFM

Step 5: Calculate the Ductwork

When we have an 88 grow tent setup with a grow room ducting fan, we are advised to maintain the ducting to a maximum of 10 feet in length (including the bends). That is not a rule or anything like that, but let us stay with it for the purpose of calculation.

There are approximately 2 bends in the ducting as a result of multiple turnings and modifications. As a result, fan size = 560 CFM + (560 10%) + (560 40%) = 840 CFM. Fan size = 560 CFM + (560 10%) + (560 40%) = 840 CFM.

Step 6: Calculate the Lights

Lights, which act as heat sources, are meant to increase the CFM need by 10% for each bulb. However, because we use an air-cooled HID lightset, these will not cause the area to become hot. And we don’t have to factor it into our calculations either. Fan Size= 840 CFM + 0= 840 CFMFinally, thegrow room extractor/exhaust fan calculatorrecommends that we choose a fan with a capacity of840 CFM or greater.

Intake Fan

Are you finished with the calculation of the grow room exhaust fan size? Now is a good time to introduce some fresh air into the grow chamber through the air intake fan. Once you’ve determined the size of your exhaust fan, determining the size of your grow room intake fan is rather straightforward. In the grow chamber, there should be a tiny negative pressure in the air. That implies you have to take in slightly less air than you exhale in order to maintain the same pressure. It follows that the CFM of the intake fan cannot be as high as the CFM of the exhaust fan, for obvious reasons.

So, based on our prior data, the final intake fan size is 714 CFM (840 CFM – 15%) = 714 CFMSo, the final intake fan size is 714 CFM (840 CFM – 15%).

Quick Recommendations(for Grow Tent)

There are a limited number of grow tent sizes available, and determining the appropriate grow fan size can be a time-consuming procedure. For normal grow tent sizes, we’ll supply you with a fan size that has been calculated in this section of the grow room fan size calculator guide:

Boost Grow Room/Tent Fan Life By Doing These

You should be aware of how critical it is to have a fan in a grow room. Being a little more cautious about a few things might help to extend the life of these gadgets. Let’s have a look at how-

Don’t Mismatch Your Ducting and Fan Diameters

Already, ducting is a significant factor in lowering the fan efficiency. The situation becomes much more dire if your fan and ducting have adiameter mismatches, as described above. As an illustration, a combination of a 6′′ fan and 4′′ ducting will result in airflow being slowed. Summary: Make an exact fit between the fan diameter and the ducting diameter when designing your system.

Induce Active Air Intake Instead of Passive

If you’re dealing with a medium-sized grow room or tent, a few air intake holes will not be adequate to draw in enough fresh air to keep things running well. In order to keep up with the wind pressure and air supply in grow spaces that are higher than 8’8″ or so, active air intake fans for grow rooms should be used. Also, find out how to set up an exhaust fan in a grow room to ensure optimum efficacy and efficiency.

Use A Centrifugal Fan

Growing in tiny tents or rooms with squirrel type grow fans is an excellent option. Centrifugal fans, on the other hand, are more appropriate for bigger spaces with higher extraction power requirements. The calculations for the grow room fan calculator in this post were all created in this manner, in fact, throughout the whole text.

Centrifugal fans are those that are used in conjunction with an air conditioning panel, ducting, and a carbon filter to circulate air. It will filter the air in your home, chill the grow lights, and ventilate the garden air as well as provide other benefits.

Control Your Fan Speed

You must provide varied levels of air ventilation for your plants depending on their development stage and the season. If we take the vegetative stage as an example, it should be higher than it should be during the seedling period. And a fan speed controller can help you do this. Using timers, some of their more complex models allow for this CFM fluctuation to be pre-programmed in advance. In addition, make certain that the fans have a suitable on-off cycle.

Protect from Bugs

The inlet/outlet fan is normally situated close to the ground surface of the machine. Because the air near the ground has a lower temperature than the air above it. However, this increases the likelihood of bugs, dust, and airborne diseases entering the building. Maintain the protection of your grow room fan arrangement by installing a bug mesh into the inlet fans to eliminate this hazard. It will also help to lessen the amount of noise generated by the grow room exhaust fan. You have, on the other hand, recommended that you use the quietest grow room exhaust fan available.

When Exactly You Care About Fan Size?

We know that you, as a dedicated grower, already have an idea of what you want to do next. But let us consider the significance of accurate grow room fan cfm calculation for the time being –

Growing Plants Demands More Airflow

In the early stages of a plant’s growth, the leaves are less in size than they eventually become. As a result, the amount of CO2 that they absorb from the surrounding air is not that significant. A good wind around the leaves may be able to provide them with the necessary carbon dioxide supply. However, as they mature, their leaves increase larger, necessitating the production of CO2. Photographic activities like as photosynthesis and transpiration are carried out more often. CO2 (for photosynthesis) and oxygen (for transpiration) are becoming more scarce as the climate warms.

In order to do this, more powerful and consistent extractor fans will be required, but the passive and active air intake systems will remain operational.

To Evacuate Excess Heat

A grow system’s primary heat sources include lamps, lights, and pumps, which are all widespread in the industry. They become the primary source of heat and temperature in a closed-off grow room environment. Unless you provide adequate ventilation, they will soon elevate the temperature to 100 degrees Fahrenheit or more. When the temperature rises to this level, plants begin to develop more slowly and are more susceptible to heat stress. Even in the worst-case situation, they may succumb to their injuries.

In addition, the humidity in the grow chamber will rise as a result.

Final Words
