## What Size Carbon Filter For Grow Tent – [In Depth Guide]

Growers! Are you ready to begin your indoor gardening projects? Do you have a plan in place? Suddenly, there comes an unpleasant odor—Oops! Most likely, it’s coming from your grow room or greenhouse. What is the explanation behind this? Your carbon filter is not functioning properly. Why? You did not size it appropriately for your grow tent requirements. What size carbon filter should I use for my grow tent? There are many sizes of carbon filters available, depending on the volume of grow tents and the amount of air moving through them.

When it comes to filter sizing, other considerations such as available space for mounting the filter, temperature, and the number of lamps placed play a secondary role.

In this case, you would have to install a filter with a CFM value that is 20 percent higher than the one you estimated.

## How To Select The Right carbon Filter

It is not a trick to know how to choose the appropriate size carbon filter! In order to complete the task, some mathematics and common sense are required. Here are a few pointers that will help you be smart and knowledgeable when it comes to picking the appropriate materials.

• First, determine the size of your grow room and then select a filter that is appropriate for the space you have available.

This formula may be used to calculate the volume of a container. VOLUME=LENGTHxWIDTHxHEIGHTI Some grow tents do not have height markings, therefore you will have to estimate it yourself.

• Following the measurement of volume, it is necessary to calculate CFM, which stands for cubic feet per minute. The cubic feet per minute (CFM) figure indicates how much air your carbon filter will clear out in a minute. It is necessary to repeat the arithmetic in order to determine CFM.

You can calculate it by dividing the volume of your grow tent by three. CFM=Volume of Grow Tent 3Both volume and CFM will assist you in determining what size filter is appropriate for your tent.

• Carbon filters with a size range of 6″ or above are the best match for tents with 400CFM or greater.
• Similarly, a carbon filter in the size range of 8″ is appropriate for 700CFM and higher.

Always read the label on the filter and make sure that you are selecting the correct CFM for your tent size based on the information on the label. In order to save money, I propose that you get a filter that is in the size range of a CFMvalue that is 20% greater than what you calculated. It will help to lower the risk factors.

## Things To Know Before Sizing Carbon Filter

Growers! Do not order a carbon filter unless you have thoroughly read this article first. If you have finally decided to install a filter to remove odors, you should consider the proper size of the filter. Keep these critical considerations in mind, and then make the best decision possible.

• Dimensions: Consider if your tent has enough area to contain a filtration device or whether you will need to purchase one. Make use of the mathematic formulas listed above to do this. Temperature
• You should also take the climate in your location into consideration
• If it’s very warm, enough cooling and fanning would be required in addition to the Carbon filter
• Setup has been completed
• Size your filter in accordance with the requirements of your Setup. In some cases, growers place filters outside the tent, while in others, they place them inside. As a result, pick the appropriate size. Calculate the internal volume of a container. The internal volume of a cubic meter is possibly the most important information when determining the appropriate filter size. Calculate it using the Length x Width x Height formula, as shown below. Light
• The size of the filter should be able to be adjusted according to your lighting requirements. If you’re utilizing high-pressure lighting, go for a wider range of CFM to achieve better results
• Otherwise, stick with the smaller range. This is yet another decisive aspect that might assist you in making the appropriate size selection. It is expected that the CFM will be larger than 700 and the c filter will be more than 8incch or higher.

## What Size of Carbon Filter for 4×4 Grow-tent

A 44 grow tent is an excellent choice for first-time growers. It is readily capable of accommodating 4 to 6 medium-sized plants. This tent is not quite large enough to accommodate a giant filtration apparatus of this size. As a result, a 4-inch carbon filter is an excellent fit for this size tent when it comes to filtering the air within. Another point to mention is that a 4inch filter will be effective for typical pressure sodium light. The size of the filter would need to be increased from 4 inches to 6 inches if you intend to utilize High-Pressure Sodium lighting.

It is always recommended to select grow tent lights, fans, and filters based on the size of the tent, the predicted temperature, and the expected humidity level.

## What Size Carbon Filter for 10×10 room

Have you ever fantasized of having a vast garden indoors? Yes, you can buy 1010 grow tents and use them to grow your preferred crops in a controlled environment with lots of room and temperature control. A large area will necessitate the use of specialized equipment to purify the air of all types of chemicals and odors. 8″ carbon filters are the perfect complement for a grow tent that is 10×10 square feet. You should never use a filter for this size that has less than 200CFM flow. The smallest filter size for this tent should be 8 inches in diameter at the very least.

Making the proper decision at the appropriate moment is critical, and this can only be accomplished via knowledge.

As a result, always conduct thorough research before purchasing any product.

## What Size Carbon Filter For 3×3 Grow Tent

Three-quarter-size grow tents are classified as tiny tents and are appropriate for growing 2-4 large or medium-sized plants in one area of space. In this case, the interior space or volume is insufficient to accommodate large filters. As a result, a 4-inch carbon filter will effectively clean the air and absorb odors in this 3-foot-square tent with no effort. A 6-inch filter, on the other hand, is preferable in this situation if you are employing high-pressure lighting. You may not be able to regulate the temperature if you do not do so.

## Carbon Filter Size Calculator

Is it difficult to decide which size to buy? But don’t worry, we’ve come up with a mathematical answer to your dilemma. The first thing we need to know before making an order for the filter is the volume of the grow tent, which we can figure out by measuring it. Here is a formula that will assist you in determining the volume of liquid. CFM Volume is defined as the sum of the length, breadth, and height. After determining the volume, you may compute the CFM, which is the quantity of air per cubic meter cleaned in a minute after determining the volume.

There is a formula written down there.

It is indicated on the filter box in cubic feet per minute (CFM).

## Where to Put Carbon Filter in Grow Tent

Before you begin sizing, decide where you want to place your filter within the tent before you begin. If it’s too heavy, growers will typically lay it close to the ground. However, following extensive investigation, it has been shown that filters suspended along the inside side of the tent top function well and efficiently. A fan linked to the filter would assist in drawing hot air outside through ducting, hence it is recommended that the filter be mounted along the roof’s eaves.

It would also aid in the preservation of your outside space for plants. Growers place the filter on the exterior of the tent in order to create more compact tents. Even while this sort of configuration is technically conceivable, it is not advised. There are safety concerns associated with it.

## What Size Carbon Filter for 5×5 Grow Tent

Is the size of your grow tent 55? Specifically, what size carbon filter would you recommend for it? The size of the carbon filter is determined by the amount of air passing through it and the amount of interior space available to install or hang the filter. The projected CFM for a 55 tent will be in the vicinity of 400. Carbon filters in the 6’x12″ and 8″x12″ sizes with a CFM of 400 or above will perform well in this application. Both have a CFM rating of more than 400. 450CFM is the capacity of the carbon filter 612; 460CFM is the capacity of the carbon filter 812.

If you are experiencing greater heat, then an 8″x12″ will work better in this situation.

## What Size Carbon Filter for 4×8 tent

Based on other criteria such as light capacity and temperature, an 8-inch filter with 700CFM or above will be an excellent fit in this situation. Fresh inline carbon charcoal filter with a flow rate of 750CFM that is appropriate for a 48 tent configuration. Additionally, the projected height of these tents is 8. As a result, the interior capacity is rather big (4x8x8) in order to fit an 8-inch filter without difficulty. If you install a 6-inch filter in this location, it will also perform satisfactorily, but not perfectly.

## What Size of Carbon Filter For 2×2 Tent

This is the smallest size tent available, and it has been built just for novices. Despite the fact that they are absolute mini-minor structures, if you wish to place filters here, you may still do so. Because it is the final smallest version, the filter size for the 2×2 growing tent should be 4 inches. Everything is now up to you to decide how you would set it up in your tent. The most effective method is to suspend it from the inside wall of the roof, so preserving some room for plantation.

## Bottom Line

It’s time to put the Carbon filter sizing tricks aside for good. Even yet, it might be difficult for individuals who do not enjoy mathematics. You should conduct thorough research and study the labels of every product you want to purchase, whether it be a carbon filter or a grow tent. I would recommend purchasing a complete kit or a starter kit. Set up according to the size of your tent, which may contain everything from a fan to a tent to a filter to lighting. Making use of the gear will reduce your chances of making blunders.

## What Size Carbon Filter Do I Need?

What size carbon filter do you recommend for a 4×4 tent? In most circumstances, a 4-inch carbon filter will be more than sufficient for a 44 camper trailer. 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. It is possible that you will be using an HPS (High-Pressure Sodium) lamp, in which case you would need a bigger 6-inch carbon filter and a higher CFM fan.

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

## Do Carbon Filters Remove Odor

A carbon filter that has been correctly installed can minimize plant smells by up to 99 percent. They may, however, have some difficulty while your plants are in their later phases of blossoming, and they will not be able to accomplish much if you are constantly opening and closing the tent. Carbon filters function by enclosing molecules in a complex pore structure for an extended period of time. Because activated carbon makes strong connections with organic chemicals, they are particularly effective at trapping terpenes, which are the primary source of plant scents.

Also required is that the grow tent be maintained in a continual condition of negative air pressure to ensure that all of the air passes through the filter and out the exhaust vent.

## 4 Inch Carbon Air Filter

Carbon filters, when correctly placed, have the ability to eliminate plant aromas by up to 95%. But if your plants are in their later phases of blossoming, they may have some difficulty keeping up with them, and they won’t accomplish much if you are constantly opening and closing the tent door. As a result of its complicated pore structure, carbon filters are capable of trapping molecules indefinitely. As a result of the strong interactions formed by activated carbon with organic chemicals, they are particularly effective at absorbing the principal source of plant scents (terpenes).

A steady negative air pressure must also be maintained in the grow tent to ensure that all of the air passes through the filter and out via the exhaust vent.

If you really want to get rid of any remaining stench that the carbon filter might have missed, you might want to look into getting an ozone generator.

## How Long Do Carbon Filters Last

If you take good care of your carbon filter, it can last for a year or even longer than that. The most important thing you can do to extend the life of a carbon filter is to keep it clean and free of debris. Dust will gradually begin to clog the microscopic holes in the carbon filter, reducing the efficacy of the filter over time. The dust will also obstruct airflow, putting an undue strain on your fan’s ability to operate. The use of a pre-filter on your carbon filter is always recommended in order to capture dust before it clogs the activated carbon in the carbon filter itself.

Inevitably, the carbon itself will degrade with time, becoming it less efficient at odor removal, necessitating the replacement of the carbon.

This might take up to a year or longer, depending on the size of your carbon filter and how hard it was forced to work throughout the course of its useful life. When you begin to notice additional scents emanating from the tent, it is a good indication that the carbon filter needs to be replaced.

## How to Clean Activated Carbon Air Filter

Because the activated carbon generates strong chemical connections with the water, it is very impossible to clean a carbon filter. So, after it’s gone, the only thing you can really do is replace it with a new carbon filter, which is expensive. Alternatively, if you only want to remove a little amount of dust and debris from the filter, you may carefully brush it off, or if it’s caught in the vents, you can gently vacuum it off. The most effective method of preventing dust buildup in the first place is to use a pre-filter to ensure that the carbon filter is operating at optimal efficiency.

• The CFM figure should be more than the exhaust minimum of the filter itself.

## 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.

1. As a result, I know that I require a minimum of a 56 CFM fan.
2. If you utilize air-cooled lights in your grow room, though, things are a little different.
3. The same is true for other heat-generating equipment such as motors and other such devices.
4. 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?
5. When compared to growing outside, this might provide some difficulties.
6. 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.
7. In the majority of situations, a 4 inch carbon filter will be more than sufficient for a 44 camper.

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

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

An inline grow tent fan (with a capacity of around 215cfm) would be sufficient for a 44 grow tent covering an area approximately 106 cubic feet.

## Do carbon filters smell?

Carbon air filters are able to filter organic compounds (gases) from the air because of the adsorption process that occurs. When a carbon air filter becomes saturated, it may begin to emit a weird stench, which you will notice. This is an extremely strong indication that it is time to replace your carbon filter.

## Can you have too much airflow in grow tent?

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

## Are carbon filters worth the money?

It is possible that the carbon air filter will be more expensive than the particle filter, which does not include carbon. If you find yourself stuck in slow-moving traffic or encountering strong scents while driving, it may be worthwhile to invest in a carbon cabin air filter.

## Will a carbon filter eliminate all smell?

Member in good standing. It is only when you have appropriate ventillation, constant negative air pressure, and the suitable size carbon filter for your ventillation system that a carbon filter will completely eliminate odors.

Also, some of the less expensive carbon filters are not up to the task of performing as they should, so invest in a high-quality filter to be on the safe side.

## How long do carbon filters last?

To put it simply, carbon filters need to be replaced after 18-24 months of continuous (24/7/365) use. Depending on how harsh the environment is, they can endure up to 4 years. This lifetime, on the other hand, is dependent on the carbon quality, consumption, humidity, and plant species, among other factors.

## Does carbon filter go inside outside grow tent?

There are several reasons why you should avoid storing your carbon filter outside of your grow tent. Inside a Grow tent, you will not be able to adequately filter out dust, dirt, and other contaminants. The filter is unable to gather and cleanse sufficient amounts of air from your Grow tent. Your fan will be under strain as it attempts to push more air outdoors for filtering.

## What do I need for a 4×4 grow tent?

In this case, the total light power required for a 44 grow room is around 800-1200 watts. You may get it from a single 1000-watt bulb or from a number of 600-watt lamps. There are many growers who believe that one 600w light at a near height might be beneficial. However, unless you’re growing in a 3/4-inch pot, a 600-watt bulb will not enough (or smaller tent).

## Can you leave your grow tent open?

## 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.

## Should I run my carbon filter 24 7?

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

## Do you need carbon filter for veg?

No. It’s a waste of your carbon filter, and it limits the movement of air in your home. I don’t bother until about halfway through the flowering period. No, but because my veg tent is right next to my flower tent, I simply use the large fan to bring both tents together.

## What size exhaust 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.

## Does a carbon filter need to vent outside?

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

## Does Grow Tent need intake fan?

When employing lighting systems that are less than 400 watts, passive intake air is the most effective. 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.

## 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 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.

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.

### 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.

## Carbon Filters: Should I Use One in My Grow Room?

So you’ve finished building up your grow room and have begun cultivating some plants in it. Congratulations! You may not be aware of it at first, but gradually you will discover that your growing area has a distinct odor. Chances are you’ll want to keep the smells of your grow area to yourself, whether it’s the strong fragrance of your plants or a slight stench from the humidity in the air. Use of a carbon filter in your grow room is highly recommended, especially if you want to keep the operation’s location secret or if you just want to keep the odours from your growing space out of your home.

## What Are Carbon Filters?

A carbon filter, like most other air filters, is intended to cleanse the air that enters it while also exhausting new air into the surrounding area. Using carbon media, these metal cylinders are filled with air and connected to a high-output fan in order to remove smells and particles from the air in your growing environment. In order to accommodate the size of your grow room and the quantity of filtering you want, carbon filters are available in several different sizes and configurations.

When your grow room is correctly set up, all of the air from your grow room will pass through the filter, and the scents in your grow room will be completely eliminated.

## How Carbon Filters Work

It is, in fact, pretty straightforward: CO2 filters operate by capturing and retaining undesired odors (odor particles) and dust particles, allowing only clean and fresh air to pass through the tube. Carbon filters are made of a variety of materials, however the majority of them, including Yield Lab carbon filters, are made of charcoal. Porous in nature, it may be utilized for a variety of applications ranging from removing specific gases from the air to lining face masks and other protective gear.

Adsorption, which is the act of capturing molecules from the air, is possible through the use of these holes.

Of course, air does not simply float into the carbon to be filtered; it must first pass through the carbon.

In order to prevent dust and odor molecules from escaping or spreading outside your grow room orgrow tent system system, the fan draws in all of the air in your grow room and pushes it through the filter, which effectively blocks the air from leaving your grow room.

## Using a Carbon Filter in Your Growing Area

The following are some crucial considerations to bear in mind when it comes time to begin employing a carbon filter in your growing environment:

### Find the Right Size

Despite their similarities, all carbon filters are not created equal. Carbon air filters come in a variety of sizes, depending on the size of your growing space and the cubic feet per minute (CFM) value of your exhaust fans. The size of your carbon air filters will depend on these factors. You will need to complete the following procedures in order to calculate the CFM value:

• Obtain the dimensions of your grow room or grow tent: height, breadth, and length. In order to determine how much space you’ll be occupying, multiply these numbers by one another, as follows: Calculate the value by multiplying it by the current exchange rate (the number of times you want the air to be completely exchanged each hour). Once per minute multiplied by 60 equals a continual flow of fresh air
• To achieve this, multiply by 60 equals once every minute
• Your CFM is calculated by dividing this value by 60.

The most accurate technique to determine what size carbon grow room filter to use is to make sure that the CFM value of your filter is either equal to or lower than the CFM values of your grow room and exhaust fan combined. Consider the following scenario: you have a5ft x 5ft x 8ftgrow tent:

• Multiply5x5x8. This amount is equivalent to the cubic feet of your growing space (200)
• The cubic feet (200) are multiplied by the number of exchanges every hour (60), resulting in a total of 12000
• A total of 200 CFM may be obtained by multiplying that amount (12000) by the number of minutes of exchange in an hour (60). Take the 200 CFM that you now have and seek for a filter that meets or surpasses that CFM

As a general rule, it is usually preferable to exceed your CFM requirements rather than to fall short. If you purchase a smaller filter than you would use, the carbon will be depleted rapidly.

Once you’ve determined what size filter you’ll need, you’ll want to be certain that it’s set up correctly. In order to get the most out of your carbon air filter, you must make certain that it is filtering all of the air that is circulated throughout your grow room. This implies that you must connect it to a grow room fan and connect ducting to it, and then carefully seal it with duct clamps after that. Place the fan and filter above or near your plants to maximize air circulation.

Then, place the fan so that it draws air from your grow room and exhausts it into the filter, as shown. This configuration will ensure that all of the molecules in the air will pass through your carbon filter before any air is allowed to escape your growing space.
