How To Set Up Fan And Filter In Grow Tent


Make your grow tent clean and odor-free by properly installing a carbon filter system and an inline fan system in your growing space. When growing plants inside, there may be a lot of undesirable scents and potential pollutant issues that can be harmful to both you and your plants’ health if not addressed. Installing a carbon filter and an inline fan system in your grow tent will help to alleviate both of these problems. Mold and mildew contamination concerns are often resolved by maintaining a proactive and clean garden, however not everyone is as conscientious as you may think.

But how can you assure that it is correctly configured to clean the air in the manner in which it is intended to do so?

I’ll go over the most prevalent layouts and explain why one is preferable to the other and why.

Conduit should be run from the filter to the fan and then from the fan to the exterior of the tent.

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 additional steps to make your grow space church as quiet as possible. Making the decision to choose a fan with speed controls and a CFM rating that is 25 percent more than your minimal need will allow you to run the fan at lower speeds without compromising performance.

If you want to further muffle the sound of your active exhaust fan, you may attach a silencer to it, which will lessen the sound of the intake fan.

Hydroponic Grow Tent Fan and Filter Setup Tutorial

There is a lot to consider when setting up your fan and filter combo since it requires a configuration that can transport fresh air, heat, and odours out of a grow tent and replace them with fresh, cold air as effectively as possible. This morning, we’re going to show you numerous different methods to set up your fan filter with air, also known as a grow reflector, as well as the best sorts of setups for different grow tent sizes. The first configuration is our most cost-effective fanfilter configuration.

  • In order to prepare for installing the exhaust system, we first install the cooler and filter, then use duct tape to connect the filter to the hood and pool the duct tape on the other side.
  • Then, either on the inside or outside of the grow tent, install a fan and secure it using duct tape on both sides.
  • This configuration is excellent because your exhaust fan is employed in three ways: it helps pool stale air from the grow tent, it helps scroll the aromas inside the grow tent, and it helps pool the heat from the grow ball out of the grow tent, all of which are beneficial.
  • This is because adding duct tape and bending that duct tape can create air exchange.
  • That is a significant reduction of CF fans, but increasing the number of fans will help to alleviate the situation.
  • This contributes to keeping the grow tent cooler.
  • Plants will grow more vigorously if the temperature and humidity are consistent.
  • This will help to exhaust the real room and scrub the stench.
  • Because grow tents do not have a bottom bed hall, the greater your level, the more duct tape you will need to get to the lowest section of the room, which is usually the coldest area of the room.
  • This identical arrangement is also effective with drool-air-cool reflector configurations.
  • If you have any other suggestions or ideas, please share them with us in the comments area below.

How To Set Up a Carbon Filter In A Grow Tent

It’s important to remember that while growing inside, the last thing you want is for musty plant aromas to fill your house, unless you’re growing something fragrant and gorgeous. Indoor growing can also produce odors and contaminants that are potentially toxic, such as those produced by soil, fertilizers, and the plants themselves. The most effective remedy for this would be to incorporate activated carbon filters into your airflow system in order to control smells and pollutants. Using this article, I’ll teach you how to set up a carbon filter in your grow tent, which will allow you to manage and clean the air while still keeping effective circulation.

First let’s start with all the stuff you will need:

  1. Filter with carbon that is appropriate for the size of your growing tent
  2. There are a variety of sizes available, but most commonly they are available in 4, 6, and 8 inch widths
  3. To connect your carbon filter to the fan, you’ll need aluminium ducting or another form of ducting
  4. Normally, this is included with the carbon filter so you won’t have to seek for ducting that fits the size of your carbon filter
  5. Heavy-duty rope clip hangers and other hanging devices are available. Duct clips are used to provide an airtight seal between your fan and the fitting
  6. You’ll need an appropriateextractor fan for your grow tent to keep the airflow under control. Duct tape is used to produce a more secure closure. (Aff.links)

Once you’ve gathered everything, you’ll be able to begin setting up your carbon filter in your groom room.

Let’s Begin!

The exhaust system is where you should install your filter. When installed on Can-Fan and Max-Fan exhaust fans, Can-Lite activated carbon filters provide long-lasting, constant filtering performance with minimum resistance to cause airflow loss, resulting in lower operating costs. Using clip hangers, the filters and duct inclined fans may be hung from tent supports in rooms with walls and ceilings, or they can be affixed to a solid surface in spaces with no walls or ceilings. Your filter should be installed on the intake side of the fan in order to remove impurities from the airstream before they reach the housing of the fan.

Instead of blowing air into the filter, you should be drawing air through it to avoid dust, mold, and other particles from clogging the activated charcoal in the filter itself.

In order to get optimal airflow in an enclosed grow area, it is necessary to locate the intake fan at the bottom of the room so that the heavier air that collects at the bottom of the room is drawn in by the fan.

Depending on your configuration, it may not be required to exhaust the air that is pulled through the carbon filter outside of the growing area, but rather to return the filtered air to the growth area as soon as it is pulled through the carbon filter.

As a result, the carbon filter will continually “clean” the air in the growing area, removing smells from the environment.

Does it matter if the carbon filter is outside or inside?

In a nutshell, no. You can have the carbon filter outside the grow tent and inside the grow tent, or you can do both at the same time. One of the most important considerations is that your extractor fan pushes the air from your grow room/tent out via your carbon filter as efficiently as possible. It normally doesn’t make a difference as long as the air is passing through the filter; otherwise, foul odors and musty plant odours would emanate from the filter.

How can i reduce the noise and make it smell nicer?

When carbon filters and extractor fans generate a lot of noise, you may wish to put your extractor to a wall for reduced vibration, or you may want to hang your extractor inside the grow tent with the filter to reduce the amount of noise. Using a sponge air freshener within the filter to provide a pleasant fragrance around your grow area is another option. Alternatives include upgrading to acoustic-insulated ducting to eliminate vibrations altogether.

How to Set up a Carbon Filter in a Grow Tent or Grow Box

If you’re growing inside, the last thing you want is for your house to smell like a musty plant, unless, of course, you’re growing something that smells delicious! Using this short guide, I’ll walk you through the process of installing a carbon filter in your grow tent. Please keep in mind that there are many other ways to set up a carbon filter inside your grow tent, and this is just one of them that is extremely simple to do. First and foremost, you’ll require the following miscellaneous items:

  1. You should use a carbon filter that is appropriate for the size of your grow room. Connect your filter to the fan using aluminum ducting or another type of ducting. Duct clips are used to create an airtight connection between your fanfilter and your ductwork. YOYO hangers and other types of hanging equipment Duct tape is used to create a more secure seal. An extractor fan that is appropriate for your grow tent

Once you’ve gathered the materials, you’ll be able to set up your carbon filter in your groom room in five simple stages.

  1. Make sure your extractor fan is outside of the grow tent while not in use. Connect the ducting to your carbon filter and tighten the duct clamps to ensure a good connection. Mount your carbon filter to the roof bars of your grow tent using YOYO hangers to keep it in place. Distribute the ducting via one of the ventilation holes in your grow tent
  2. And Construct an extraction system by connecting the ducting to the extractor fan with duct clips.

You’ve completed your task! An example of a carbon filter installed within a grow tent may be seen below. There are several different ways to skin a cathang a filter, including: One often asked issue we receive here at is whether the carbon filter / fan should be placed inside or outside the grow tent. The answer is easy — you can do both at the same time! Ensure that your extractor fan draws all of the air from your grow room out via your carbon filter. It doesn’t matter which direction your extractor fan is configured as long as all of the air is passing through the filter.

As a result, carbon filters and extractor fans might create a lot of noise at times.

  • Install your extractor against a wall to reduce vibration. If you like, you may hang your extractor fan inside the grow tent next to the filter
  • Set an air freshener with a sponge inside your filter to provide a nice fragrance throughout your grow space. Upgrade of acoustic ducting in order to reduce vibrational noise

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 enlarge) 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. Remember heated air stays at the top of the tent so don’t hang 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. 3) Link the ducting: Connect the ducting to the output side of the grow tent fan, wrap it in either zip ties or metal brackets, and connect it to the hooks on the ceiling.

Use the clamp or zip tie that has been given.

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

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.

  • You may also set a timer and receive alarm notifications.
  • When my AC Infinity T4 was running at maximum power, I was pleasantly pleased at how quiet it was.
  • This results in the fan motors being loud.
  • 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.

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?

Since the carbon filter is where air will be entering your fan, you should put it at the top of your tent to collect the warmest air. 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.

Grow Room Intake and Exhaust Setup – Tips

The ability to adjust the environment in a grow room is vital to the operation of a well-functioning, productive facility. Plants thrive in well-designed environments that provide clean, odor-free air as well as optimal temperature and humidity conditions that promote plant health. How can you increase air circulation and ventilation in your grow room in order to maintain a safe and healthy environment for both the plants and the people who work in there?

Choose the Right Intake System for Your Setup

When the lights are on, the air in your grow room should be refreshed every 5 minutes, and more frequently if you are having difficulty controlling heat and humidity. This can be performed using a passive or active intake mechanism. Which is the most effective? It is most appropriate for small to medium sized institutions. Passive intake is recommended by HVAC mechanical professionals for the majority of grow tent systems. Instead of utilizing an air intake system, passive systems make use of an inline exhaust fan, which creates a vacuum that sucks stale air out of the tent while simultaneously drawing in new air via intake holes at the tent’s bottom.

Your grow room must be a negative pressure environment, meaning it must have a lower pressure than the surrounding environment in it to operate effectively. Because passive systems aren’t totally sealed, they are more susceptible to insect infestations and odor concerns than sealed systems.

Small to moderate-sized institutions will benefit the most from this option. The majority of grow tent setups, according to HVAC mechanical professionals, require passive intake. An inline exhaust fan is used instead of an air intake system in passive systems, generating a vacuum that sucks old air out of the tent while drawing in fresh air through intake holes at the tent’s base. Your grow room must be a negative pressure environment, meaning it must have a lower pressure than the surrounding environment in order to work effectively.

Grow Room Ventilation Configurations

Your business HVAC firm may propose one of many ventilation configurations, including placing the filter inside and the fan outside, placing the fan inside and the filter outside, and placing both the fan and the filter outdoors. However, putting the fan and filter within the unit is the ideal option for ensuring best performance with short, straight ducting that promotes efficient airflow, as opposed to the outside. In the end, the location of your grow lighting system and reflectors will determine the final design of your system.

The Importance of a Properly Sized Grow Room Ventilation System

Your business HVAC firm may propose one of many ventilation configurations, including placing the filter inside and the fan outside, placing the fan inside and the filter outside, or placing both the fan and the filter outdoors. In order to guarantee best performance, it is preferable to locate the fan and filter within the unit, with ducting that is short and straight to allow for efficient air movement. The location of your grow lighting system and reflectors is critical in the final design of your system.

Installing Grow Room Ventilation

With an adjustable rope, inline fans are often linked to the additional ceiling bars on your tent’s sidewalls. Depending on the use, it may be installed directly into an exhaust hole or to ductwork that runs through the port. Carbon scrubbers are hung in the same way as the inline fan, with the inline fan acting as a support. Outside air is drawn in from the bottom, passed through the filter, passed through the lights, passed through the inline fan, and then expelled outside.

Carbon Filter Outside Grow Tent- Guide & Warnings

Home»Environment»Carbon Filter Outside Grow Tent- GuideWarnings9075Views0 Carbon Filter Outside Grow Tent- GuideWarnings9075Views0 Perhaps your grow tent isn’t up to the task of housing a 16-pound carbon filter in the first place. However, you still want it to be there in order to filter out the foul odor. In this case, you’re considering installing the carbon filter outside the grow tent.

Despite this, it may have certain unintended repercussions. However, it is still feasible to retain the carbon filter outside the tent and ventilate the air so that it does not smell. In today’s post, we’ll explain how to do that. Keep an eye out for more information.

Why Put The Carbon Filter Outside Tent?

First and first, this is not a suggested course of action in any way. First and foremost, you should keep your carbon filter (as well as your fan) inside the tent. However, if you find yourself in any of the following scenarios, you may need to reconsider your position-

Your grow tent size is too small

Carbon filters are typically 6″ or 4″ in diameter with a length ranging from 16″ to 24″ in length. If the size of your grow tent is between 10 and 30 square meters (24, 48, 48, etc.), you may have difficulty accommodating the filter.

Your tent might not be strong enough

You can’t always rely on the strength of your grow tent to keep you safe from the elements. As a result, hanging a 16-20 pound carbon filter might become dangerous. Furthermore, if it is knocked from its perch, it has the potential to start a fire, destroying all of the plants in an instant.

You Don’t Want to Waste Grow Space

When the carbon filter is too heavy or too huge to be suspended from the grow tent roof, many of us may consider placing it on the floor of the grow tent instead. However, this takes up a significant amount of your growing area, which is at a premium. Another advantage is that it will bring warm air down to the plants, which is detrimental for a high harvest. The most ideal alternative to this design is to retain the fan within the tent and the carbon filter outside the tent, which is the most desirable solution.

Items You Need

  1. The carbon filter
  2. The inline fan
  3. The inline fan silencer (which is only applicable to setup 2)
  4. Kit for flanging ductwork. (In order to make airtight holes in the grow tent)
  5. The following tools are required: a box cutter or wire cutter (for cutting ducting)
  6. Duct clamps (for securing tight connections)
  7. And duct tape (for a more secure seal).

Setting up the Carbon Filter Outside Grow Tent

The following instructions will walk you through the process of installing a carbon filter outside your grow tent. But, before we get started, I believe you should recognize something really crucial! Carbon filters are most often the first step in the process of developing a grow room ventilation system. As a result, the air first passes through the filter, where it is cleansed of unpleasant compounds. Because it sucks air through it, a carbon filter is utilized as an exhaust filter in vehicles.

Instead, air is blasted into the filter, which then serves as an intake filter for the engine.

Setup Guide 1: Fan Inside- Filter Outside

It is recommended that we retain the fan and filter on the inside of the case in case 1. Your grow tent may not be robust or large enough to accommodate the filter in this situation, but a fan would suffice. Now, here are the steps to follow:

Step 1: Prepare the Carbon Filter

Take the filter out of the package and place the pre-filter onto it to complete the assembly. There should be elastic bands available for you to use in order to secure the positioning of the pre-filter. In many circumstances, gardeners choose to position the pre-filter in the same location as the inline fan intake port on their equipment. Think about what a pre-filter is supposed to perform, and you’ll see why this would make sense.

Step 2: Find The Suitable Place for The Filter

Because we’re thinking of putting the filter outside, the carbon filter should be placed as “near” to the vent hole as is reasonably practicable.

The reason for this is that if it takes a significant length of ducting to reach the filter, the airflow will be significantly reduced. As a result, the filtering process of the carbon filter will be slowed down significantly.

Step 3: Cut Ducting at the Required Length

Given that you’ve placed the inline fan within the tent, you’ll need to connect it to the filter on the exterior of the structure. Measure the distance between the fan flange and the filter flange with precision. And then cut the ducting to the precise length you need it with a box cutter or wire cutter. With aduct flanging kit, you can be certain of accurate and leak-free functioning.

Step 4: Connect The Filter Flange with the Fan Flange

After that, connect the ducting to the fan’s tapered end and route it outside through a vent hole. Keep in mind that the vent hole and the inline fan should be on the same line. This will help to reduce the amount of airflow that is lost to the filter. To finish, use duct tape and duct clamps to secure the vent hole, the fan-ducting junction, and the filter-ducting joint together.

Setup Guide 2: Both Fan and Filter are Outside

Growers may want to locate both the fan and the filter outside under some circumstances. This is especially true when the fan-filter combination is expected to remain in place. In such instances, you must devise a method of reducing the tremendous amount of noise generated by inline fans. Taking that into consideration, here are the steps-

Step 1: Place the Carbon Filter Ready

Remove the carbon filter from the previous setup and install it on the new location, just as you did in the first step. Make every effort to keep the filter as close to the tent as possible.

Step 2: Put the Fan on Top of the Filter

Removing and re-installing the carbon filter is quite similar to the first step of the prior setup. Keep the filter as close to the tent as possible to ensure that it does not become clogged.

Step 3: Cut the Vent Hole and Ducting

Create a hole in the tent wall if it does not already have one if it does not come with one built in. For an exact cut, a duct flanging kit should be used. Make sure that the diameter of the fan is the same as the diameter of the blades. Now, measure the distance between the vent hole and the fan and cut a piece of ducting to that measurement. In this phase, you will need to utilize a box cutter or wire cutter, as you are aware.

Step 4: Secure Connections

Duct foil tape and duct clamps should be used to secure all of the connections. The following connections should be located beneath the rudder: the vent-ducting junction, the ducting-fan joint, and the fan-filter joint. Problems-

  1. It is possible that the fan will not suck as much air from the outside as it might from the inside. When the fan is located outside, it will be incredibly difficult to reduce inline noise.

Consequences of Keeping The Filter Outside Tent

As we stated at the outset, placing the carbon filter outside is not a recommended mode of operation. It has a variety of disadvantages, especially if you’re concerned about carbon filter number one. At this stage, we’ll demonstrate the ramifications of your actions-

You’re Defeating The Purpose of the Pre-filter

It has already been stated that placing the carbon filter outside is not a recommended procedure. When it comes to carbon filter 101, there are some disadvantages to using this method. At this stage, we’ll demonstrate the ramifications of your actions.

You Can Not Draw Air Through The Filter Anymore

Despite the claims of many manufacturers, carbon filters are not equally effective in drawing air in and out of a system from both directions. In this situation, we’re extending it outwards from the center. And this will result in a decrease in the effectiveness of the filter. Additionally, this inefficiency may have an impact on the predicted output from your growing space.

Treatment:There is no effective treatment for this. You’re going to have to deal with the problem one way or another. However, placing an oscillating fan at the bottom of the structure may help to circulate the air and decrease the impact to some amount.

The Fan has to Work Harder

Irrespective of whether the fan is located inside or outside the tent, it must exert more effort in order to direct exhaust air into the filter. If there are a few of turns in the ducting, the job may become much more difficult. Solution: Purchase a fan that has at least 5-10 percent greater CFM than the one recommended by your grow system. Maintain the ducting’s length and straightness to the greatest extent practicable.

It Might Catch on A Fire

We can see from the preceding statement that the fan is subjected to a great amount of strain when the filter/fan-filter combination is located outside the building. An increase in pressure may induce overheating in the fan motor, which may result in a failure. In the worst-case scenario, it might even result in a fire. Solution:In this case, we strongly advise you to go for inline fans that are equipped with circuit breaker help. If the fan experiences any further stress or heat build-up, it will immediately shut down and turn off.

Safety Concerns

Is it OK to place the carbon filter outside the tent? It’s possible that you’ve received the answer along with detailed instructions. The following are some safety recommendations that you should bear in mind:

  • Electric fans with circuit breakers should be used
  • Ducting should be kept short and straight
  • Install a pre-filter at each point where air will come into contact with the ducting to filter it. Utilise an air-conditioning fan that delivers 5-10 percent more CFM than the grow system requires. Make sure you utilize an electric inline fan with a circuit breaker
  • Otherwise, the fan will not work.

For example, if you wish to collect unpurified air from a grow tent, the length of the tube should be as short as it possibly can.

It’s simple to create many inlet or outlet locations with an inline fan by utilizing do-it-yourself approaches.

Components for Creating an Inline System

  • Ventilation system requires an internal vent, which serves as the point of extraction for the system, to function properly. Generally speaking, these vents and grills are available in a variety of forms, sizes, and colors to accommodate various characteristics of a grow room environment. It is preferable to use a short vent in order to limit the distance that air must travel
  • The use of ductwork to link the vent and the motor, as well as the connection of the motor to an external vent, may be required. There are many different types of ducting available, and the most suitable for grow rooms are the flexible varieties. Another kind is semi-rigid and insulated ducting, which are two of the most common options. Fan– A fan is the most important component of a grow tent system, and the fan you choose will be determined by a number of criteria. These considerations include the size of the space and the specific purposes for which the fan is intended. Calculator for exhaust fans– this tool may be used to determine the degree of extraction necessary for a system. It is preferable to have a fan with a diameter and length that are identical to the ducting that you will be using. It is important to remember that a fan can only be used with ducting that has a specified diameter. The amount of effort that the fan must do to cleanse the air will be reduced if the length of the fan is decreased. Lastly, an external vent can be installed on the exterior wall or on the roof, depending on the design of the building. Many alternatives are accessible in this area
  • For example, As an optional feature, you may also install a backdraft shutter in conjunction with the ductwork to assist avoid problems such as air flow backward. This will also assist to keep the system closed while the fan is not in use, which will be beneficial. Duct tape should be sufficient for holding everything in place. As a result, consider including work claps into the process.

A grow room ventilation system is a device that maintains a constant flow of air between the outside world and the inside growing environment. The system also incorporates some sort of ventilation system to keep air flowing through the grow area.

How Does A Ventilation System Affect Plants?

The primary purpose of a grow room is to give plants with the optimal growth environment, as opposed to what is accessible to them outside of the facility. As a result, this also entails delivering a continuous supply of fresh air that is high in CO2. Using a ventilation system, you can keep the CO2 levels in your grow room at the appropriate range for plant growth. As the quantity of CO2 in the air decreases, it becomes necessary to maintain a steady supply of fresh air from the outside. Plants are accustomed to growing in the elements and wind of the outdoors, where they are exposed to the elements.

The following facts will help you understand why these systems are so important for plant growth:

How to install an exhaust fan in a grow tent?

It is now necessary to set up the grow tent ventilation system at this phase. It’s the part that most people find difficult, yet it’s a straightforward operation. There are a variety of grow tent ventilation configurations to choose from. Having said that, it is advised that the fan and filter be hung within the tent for maximum effectiveness. If you only have tiny to medium-sized carbon filters, this is the most effective method. It contributes to the reduction of your expanding footprint by drawing air through the filter.

  1. At the same time, it is a method of removing heated air from the upper area of the tent, which is beneficial.
  2. This is not ideal since the filter may suck in extra warm air and direct it to the plants while the system is still in operation, which is not desirable.
  3. In certain instances, though, laying the filter on the floor is the most practical solution to the problem.
  4. While this strategy is advantageous in terms of saving space, it has significant disadvantages.
  5. Furthermore, if the ventilation system is located outside the tent, it has the potential to enhance the amount of noise produced by the fan.

Before you begin, be certain that you have sufficient knowledge about the grow room’s climate and ventilation requirements. The following are some of the steps required in installing a carbon scrubber and ventilation fan:

  • The inline fan should be connected to one of the new ceiling bars in your grow area. Consider utilizing adjustable rope clip handles to suspend fans from the ceiling, which work nicely for this purpose. Either move the inline fan over so that it fits directly into the exhaust hole, or connect the inline fan to your ducting for further convenience. A convenient exhaust hole allows you to run the inline fun through and out of the machine for maximum ease. Hang the carbon scrubber — in most cases, it should come with handy ropes to make installation easier
  • Connect the carbon scrubber to the inline fan in such a way that the fan pulls air through the carbon scrubber. Consider utilizing ducting or just connecting them together if they are the same size as one another. Confirm that your components are the correct size and that they are arranged in the proper sequence. Through the bottom intake holes and up to the filter, the outside air will be passively drawn in from the surrounding environment. After then, the air is moved via the inline fan and out through the exhaust holes as a result of this innovative strategy.

The success of your grow is determined on the attention to detail. If you want to maximize your produce, you’ll need to educate yourself on the subject. How to install an inline duct fan in a grow tent is covered in this article. Read on to learn more.
