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.
- At the same time, it is a method of removing heated air from the upper area of the tent, which is beneficial.
- 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.
- In certain instances, though, laying the filter on the floor is the most practical solution to the problem.
- While this strategy is advantageous in terms of saving space, it has significant disadvantages.
- 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 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.

Plants, on the other hand, have their own set of requirements. Their need for a moderate wind and an inversion of the atmosphere, which may be difficult to achieve when cultivated inside, is understandable. So, what exactly are we looking for? What is the best way to hang an exhaust fan in a grow tent?
- After that, connect the carbon filter to the exhaust fan and check that the fan is in the proper location.
- Growing plants in grow tents necessitates the use of ventilation in this situation.
- However, in order to keep the grow tent and the plants within in good condition, you must meet the needs of the plants.
- You must ensure that your plants receive excellent quality airflow in order for them to grow properly.
How To Hang Exhaust Fan In Grow Tent? Step By Step Guide
The Best Way to Hang an Exhaust Fan in a Grow Tent Step-by-Step Instructions The extraction system for a grow tent is comprised of three basic steps: preparing the carbon filter, hanging the exhaust fan in the grow tent, and installing the ducting system in the grow tent.
Step 1 – Prepare The Carbon Filter
To begin, you must prepare the carbon filter by wetting it with water. In order to prepare for this, you must first uncover the item by removing the protective plastic coating. More information may be found at: How To Make A Carbon Air Filter For Your Grow Tent.
Step 2 – Get The Screws Back
There will be a few screws that hold the flange plate in place on the interior. You’ll have to remove those screws, lift the flange plate up, then reinstall the screws while keeping the plate in an upside-down position.
Step 3 – Cover The Plate
The dust cover should now be placed on top of the plate to protect it.
Step 4 – Connect The Carbon Filter With The Exhaust Fan
Now is the time to cover the plate with the dust cap.
Step 5 – Insert One Blade Into The Paper
Make use of your scissors to cut a single blade of one of them into the foil paper at the end of your ducting and then extend out the ducts once more around the perimeter.
Step 6 – Use Shearing MachineWire Cutter
Because the ducting pieces are moving in a spiral motion, it is impossible to separate them. As a result, the cut may come close to meeting the opposite side but will not be able to be separated. The shearing machine and wire cutter are required to separate them at the point where the foil is cut in order to do this.
Step 6 – Continue!
Now take the jack chain and cut it into two equal parts so that you may hang the filter and the exhaust fan with ducting from it.
Two portions will adhere to the ends of the duct on opposite sides. As previously noted, two different ducts will be utilized to link both the exhaust fan and the carbon filter, with two duct clips on either end of each duct.
Step 7 – Hung Together
Carbon filter and exhaust fan will be strung together outside the tent using a hanging rail before being linked in place. Slide one end of the tiny duct onto the flange plate, attach the duct clip, and tighten the screws with a screwdriver to ensure that it is secure.
Step 8 – Placement of the Exhaust Fan
Following that, an arrow will be painted on the surface of the exhaust fan to indicate the direction of airflow. Please make sure that this arrow points in the opposite direction of the carbon filter since the exhaust fan will suck the air that is coming from the carbon filter rather than blowing it through the filter. As a result, when installing the filter and exhaust fan in the grow tent, it is critical to pay attention to the direction of the fan and filter.
Step 9 – Final Check!
Slide the duct over the flange all the way around on the tiny end of the ducting and attach it with another duct clip at the other end. Then, with the last duct clip, tighten the ducting by sliding the long end over the opposite end of the ducting. It is recommended that this extraction system be positioned as high as possible in order for the air to move through it correctly. That is why it is advisable to build a grow tent ceiling rather than a floor. In order to hang the exhaust fan and filter outside the tent, you must raise them while they are suspended by the jack chain from the tent frame.
Because it will be more comfortable for you and you will not require any assistance, it is advised that you elevate them while they are not linked.
Support the exhaust fan with the straps attached to the filter and jack chain, and connect them to the hanging rail using the hanging rail connector.

How To Hang Oscillating Fan In Grow Tent? Step By Step Guide
Hanging an oscillating fan in a grow tent is a simple process. Some gardeners may not wish to utilize ducting in conjunction with an exhaust fan and filter, and they may choose for oscillating fans rather than an exhaust fan with or without ducting since oscillating fans are less expensive than other types of exhaust fans. Oscillating fans are sometimes preferable to exhaust fans because they may oscillate, allowing for a pleasant breeze to be delivered without blowing on a specific location for an extended period of time.
I’ll demonstrate how to hang an oscillating fan in a grow tent, which I found to be both simple and time-consuming to put up in my experience.
Step 1 – Use Offset Flange
Use the offset flange black with screw holes to attach it to the tent pillars, which is included with the tent. You must connect two black flanges to the back wall of the tent, one to each of the cornerstones of the two corners of the back wall. Make an effort to get the flange as near to the roof as feasible. Then you’ll need to attach a long wood piece to the corner flanges, which will be held together with screws.
Step 2 – Secure The Oscillating Fan
You must fasten your oscillating fan with the wood piece in any location you deem necessary based on your requirements. Once you have completed the installation of the entire procedure, your extraction system will be ready for use. Now all you have to do is connect in the power cord, and your plants will be ready to move inside! If you follow the steps outlined above correctly, you can be confident that your plants will receive the proper airflow and atmosphere to thrive even more than they did previously.
Keep in mind that the technique of removing and installing your plants will determine whether or not your plants develop properly. The more precisely you hang your exhaust fan, the higher the quality of the airflow you will receive and the greater the yield you will receive from your tent will be.
What Are The Facts That You Have To Be Careful About While Hanging an Oscillating Fan In Grow Tent?
In order to properly hang an oscillating fan in a grow tent, there are a few considerations that must be taken into consideration. Never allow your fan to blow wind directly into or into your plants. It should only blow wind around the plants, not directly upon them. In addition, excessive wind will cause your plants to be clawed by the wind. When an excessive amount of airflow blows onto plants, it causes wind-burned, which causes the plants to claw. When you notice the clawed plants, you could assume that the clawing is the result of overwatering or underwatering, but the most likely reason will be over-winding of the plants.
Be Careful About The Arrow
Keep an eye out for the arrow on the fan’s surface, which will tell you to the location where the exhaust fan and carbon filter should be installed. It is important not to direct the exhaust fan toward the carbon filter; otherwise, it will have a negative effect.
Take Care of The Oscillation
In the case of an oscillating fan, you should pay attention to whether or not the oscillation is functioning properly. A failure to do so will result in noise when the system is unable to oscillate normally.
Use An Exhaust Fan Calculator
The exhausting system must be checked using anexhaust fancalculator since the general temperature, humidity, airflow speed, and other variables are all aspects that must be considered in order for your plants to thrive properly in their environment.
Maintain The Diameter
Maintain the diameter of the ducting and the exhausting fan, since this is an important safety factor to consider.
Be Careful About The Cheap Ducting Fans
If you can afford better ducting fans, don’t get the cheap ones. They may claim to be able to blow a lot of air based on their CFM rate, but in reality, they don’t have nearly as much power to blow as you may expect. As a result, pick your fan carefully.
Choose As Your Room Size
You must select the duct, filter, and fans based on the size of your room or tent as well as the cost of each item. If you have a tiny tent, you should avoid purchasing a larger fan.
Ensure Better Placement
As much as feasible, hang your exhaust fan as close to the roof as possible since the higher up your exhaust fan is positioned, the more airflow you will obtain from it.
Check the humidity level on a frequent basis since plants are constantly exhaling water vapor into the air, which can cause difficulties within the tent if the humidity level is too high.
Seal The System
It is necessary to seal the entire exhausting system after utilizing it since it is beneficial in increasing the efficiency of the system. When employing a carbon filter and an exhausting system, it is critical to ensure that the air is adequately ventilated from the grow room; otherwise, the air will flow through without being properly vented. The major function of the exhausting fan is to provide suction, which is very hard to achieve without a seal.
Make Sure There is No Leakage
Check for leaks at the junction between the filter and the fan if you’re using a carbon filter to ensure that no air is leaking through the filter.
Finally, cleaning your exhaust fan is critical because if it is not cleaned, it will not function correctly and the temperature inside the tent will rise, which will limit plant development.

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.
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.
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.
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%!
- 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%.
- 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.
- This amount is multiplied by the efficiency % of each component to arrive at the final result.
- Adding in the heat output of your grow lamp (about 50%) gives us a needed CFM of 249 cubic feet per minute.
- 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.
- This will let the fan to operate at lower speeds while remaining quieter, as well as providing additional area for future expand space system growth.
Look for inline duct fans that are powered by direct current (DC) fan motors, which are the quietest as compared to alternating current (AC) fan motors. PWM-controlled EC motors are also acceptable in terms of acoustic performance.
How to Manage Grow Space Noise
There is no question that you will hear some noise when employing a high-powered fan to air your grow environment. You wouldn’t want to spend an extended period of time in an area with excessive noise pollution or catch the attention of your neighbors. Fortunately, you can plan your component selection with noise reduction in mind, and you can take further steps to make your grow area as as quiet as possible. Making the decision to choose a fan with speed controls and a CFM rating that is 25 percent more than your minimal need will allow you to run the fan at lower speeds without compromising performance.
If you want to further muffle the sound of your active exhaust fan, you may attach a silencer to it, which will lessen the sound of the intake fan.
Grow Tent Ventilation Setup & Exhaust Guide
The importance of ventilation in your grow room cannot be overstated. As a result, poor ventilation is responsible for the majority of cannabis issues and leaf symptomatology. CO2 concentrations, temperature, humidity, and other factors are all taken into consideration. Cannabis plants are only able to survive under specific environmental conditions. It is at this point that grow tent ventilation and exhaust become important.
Why Your Grow Tent Ventilation Is So Important?
Your grow tent should attempt to emulate the growth conditions seen in nature. And the greater degree of control you have over those circumstances, the better. The most important thing to remember is that ventilation and exhaust are essential. Because of this, your grow tent’s environment is favourable to healthy development, vigorous plants, and abundant yields.
Keep The Perfect CO2 Level For Cannabis
Cannabis, like other plants, need carbon dioxide in order to live. However, when plants are enclosed in a small area, the CO2 in the air will soon be depleted and replaced by oxygen if there is insufficient circulation to the plants. So we’ll have to figure out how to restock it in some way. This means that the cold, fresh CO2-filled air should be drawn into your setup while the used air is expelled out the back.
Control Humidity And Excess Heat
Bud rot occurs as a result of inadequate ventilation. Cannabis plants grow in temperatures that humans would consider to be “comfortable.” That is to say, the temperature should be between 70 and 85 degrees Fahrenheit (or 20 and 30 degrees Celsius) throughout the vegetative stage. Dropping the temperature to roughly 65-80°F (18-26°C) when your plants are ready to blossom can result in higher yields and better-quality buds when your plants are ready to flower. In addition to adjusting the temperature of your grow tent, you should also consider controlling the humidity.
If you do not have an adequate exhaust system, you may find yourself with a moist grow room where mold and fungi will begin to thrive. Believe me when I say that you don’t want anything to do with white powdery mildew or bud rot.
Avoids Pests And Plant Diseases In Your Tent
Mold and fungus aren’t the only types of organisms that producers must be on the lookout for and avoid. Protect your plants against insect pests, which can thrive in stagnant air and damp soils, as well as from other environmental factors. It is difficult for spider mites and fungus gnats to fly when they are in well-ventilated areas. This means that if you have the proper fan and exhaust system, your plants will be lot safer from these insects.
Finally, it’s vital to note that cannabis plants benefit from, and even require, a mild breeze in order to flourish at their ideal levels. This helps to give the stems a good exercise and keeps them from becoming too weak to sustain normal bud growth in the future. Your stems might get anemic if you don’t have a consistent wind blowing through your grow tent. This can lead to bowing. This, in turn, can hinder the leaves from absorbing enough light to effectively photosynthesize, resulting in a reduction in the ability of the plant to grow.
Ways To Setup A Ventilation System In Your Grow Area
It may be necessary to make an investment and experiment in order to find the optimal ventilation for your ventilation system. Nonetheless, it is a feature of your system that will almost certainly pay off in the future. For begin, there are two different methods to configure your ventilation: passive intake or active intake.
Exhaust Fan With Passive Intake
Passive intake depends on negative pressure to generate passive airflow, which is why it is called passive. Quite simply, you have a fan that is pushing air out of the tent, but there is no fan pushing air in from the other side of the tent. As an alternative, you may install an intake hole that allows new air to enter the tent passively. You can have a single passive intake hole that is approximately three or four times the size of the exhaust hole, or you can have many passive intake holes.
This approach will cut energy use and will be the most effective for the majority of farmers.
Active Air Intake And Exhaust System
Alternatively, an active intake system employs a fan to actively suck air into your grow tent. So there aretwo fans working together. One to keep the air from inside the tent from blowing out, and another to keep the air from blowing in from outside the tent. When using this system, the size of the intake hole is less important. So if your grow tent has an intake hole that’s about the same size as your exhaust hole, your tent will lend itself well to an active intake system. Since most fans allow you to change their power,you may discover your own balance that allows you to attain the perfect temperature and humidityin your tent.
The Ultimate Ventilation Setup
The fundamental concept of exhaust systems remains constant. Keeping clean, fresh air coming in while venting out old and humid air is critical for the system to function properly. However, there are other accessories and pieces of equipment that you may incorporate into your setup.
The ideal ventilation design will not only keep your crop healthy, but it will also be discrete, resulting in the least amount of noise and aromas possible. I’m going to presume that your setup includes any or all of the following components:
- The use of rope ratchets for securing your equipment
- An exhaust fan (we’re going to use a passive intake for this project)
- A carbon filter is used. Ducting and clamps are used. A deafening silencer
- A fan that oscillates
- Grow lights that are air cooled (most types of lights, such as LEDs, generate practically minimal heat and hence do not require inclusion in your ventilation system)
Ducting Your Fans And Accessories
The remainder of your equipment will be connected to your exhaust fan in the stages that follow this one, so pay attention. This will be accomplished by the use of aluminum ducting. Using flexible aluminum ducting, I have discovered that the right mix of price, adaptability, and convenience of installation may be achieved. However, insulated aluminum ducting will also work well if you want stronger duty ducting and have the necessary funds. Check for kinks and wrinkles and smooth them out if necessary to ensure peak performance.
You will have a less efficient system the longer and more roundabout your journey is.
Inline Exhaust Fan
After erecting your grow tent, the first thing you should do is connect your exhaust inline fan to it. However, you should avoid connecting anything to your power source until you’re ready to begin growing. Step inside your tent and attach your exhaust fan to the exhaust hole in the floor of your tent. Hanging your fan from the ceiling of your tent is one option. Connect the fan’s exit port directly to the exhaust hole, or duct it if you find it more comfortable, and then close the fan off completely.
Carbon Filter To Deal With Odor
Using your exhaust system to your advantage might let you develop discreetly if you like. It is possible to keep the scent of cannabis out of your home by using a carbon filter. Your carbon filter is something that has to be considered while configuring your exhaust system. In order for the air from your grow tent to be expelled outdoors, it first has to travel through your filter. Many growers choose to employ the simplest possible configuration, which is to hang the carbon filter inside the tent.
In this manner, the air will first pass through the carbon filter, after which the exhaust fan will expel the filtered air to an outside environment (first picture).
In the event that you do this correctly, the only location where you’ll be able to smell cannabis will be when you’re inside your grow tent.
Silencer For Extra Stealth
When installing a silencer, it is best to position it immediately after the fan; but, if necessary, you may place it farther down the ducting. It works by muffleing the air coming from the exhaust, resulting in significantly less noise. And they are quite effective. My tent, which is located within the home, has a suppressor placed in it, and the decrease in noise is incredible. I highly recommend it.
It also alters the sound style; it moves from being a dreadful whining to a pleasant swooshing that sounds more like wind as a result of the shift in volume. Always keep in mind that it will reduce airflow, so you’ll need to account for it when calculating CFM requirements (more on that below).
Connecting An Air-Cooled Reflector (Mostly for HID grow lights)
If you’re utilizing high-intensity discharge (HID) grow lights, it’s extremely probable that your hooded fixture can accommodate ducting. You’ll need to have direct airflow passing through the light’s reflector in order for it to work properly. This will assist you in keeping the temperatures down as well as the light bulbs cool, which is important because HID lights generate a lot of heat. Depending on your reflector and how many additional accessories you have, this can add a significant amount of complexity to your setup.
Starting with your CO2 filter and working your way up to your reflector is a good idea.
Sealing Your Grow Tent To Create Suction
A sealed grow tent guarantees that only air enters through the intake hole and only leaves exit via the exhaust fan when the tent is closed. Your exhaust system will be prone to air leakage and will be extremely inefficient if the seals are not properly installed. Sealing provides a separate environment, allowing you to regulate temperature, humidity, and CO2 levels independently. Additionally, it guarantees that your exhaust system is running at maximum efficiency. Your exhaust fan will generate negative air pressure as a result of reducing air leakage, allowing fresh air to enter via the intake hole.
When used in conjunction with a carbon filter, this will further reduce the likelihood of cannabis scents penetrating your house.
However, if you have tears or pinholes, you may use anything from duct tape to Black RTV Silicone to close them up again.
Check For Air Leaks
To check for air leaks, start by turning on your system and closing your tent from the inside outward. Moving an incense stick about the interior of your tent and observing its behavior can give you a better understanding of its behavior. If the smoke rises straight up into the air, the air is exactly where it should be. To finish, take the incense stick outside the tent and position it near to the intake hole on the other side. If the smoke snakes towards the intake, this is a strong indication that you have accomplished effective sealing and negative pressure in the engine.
Oscillating fans are both inexpensive and quite effective. The process of blowing and spreading air uniformly within your grow tent, while also ensuring that the wind is powerful enough to keep the stems of your plants strong You may use floor fans that are placed in a corner of your room or grow tent fans that are much smaller and clip on to the poles of your tent to keep the heat out. It’s possible to hang it or place it in your room if you’re a bit of a do-it-yourselfer and you have a fan laying around.
The number of fans you need will depend on the size of your grow tent and the size of the fans you use.
You may just require one or you may require several. There is no straightforward method of determining how many you require. However, attempt to position the fans in such a way that your entire crop receives some air circulation.
How To Calculate CFM For Exhaust Fans
To properly ventilate your grow tent, you must first determine how much fresh air is required in order to guarantee that your plants develop in a healthy manner. You may determine the appropriate Cubic Feet per Minute (CFM) required to ventilate your tent using a formula, which is provided below.
1. First let’s find out your grow tent’s volume
While the height of your grow tent may vary, we’ll use a 4×4 grow tent with a pretty standard 8′ height as an example. (width) * (depth) * (height) = 128 ft 3 (width * depth * height)
2. Calculating Base CFM
The amount of air in your grow tent should be replenished by your inline fans once every two to three minutes, at the absolute least. The following is the formula: 128 feet/3 minutes =64 CFMB However, the temperature and humidity of the surrounding environment must be taken into consideration. If the room from which you’re obtaining the air is excessively hot, add an additional 20% to your calculations. And if you’re dealing with high humidity, increase the percentage by another 40%. In a hot and humid environment like mine, the result might be something like this: 64 (cfm) multiplied by 1.4 (humidity) multiplied by 1.2 (warm climate) Equals 108 Base CFM This implies that in order to adequately ventilate your 128ft 3grow tent, you must exchange 108 cubic feet of air every minute.
3. Factoring In Accessories
Now that you’ve calculated your basic CFM, you’ll need to add in your accessories, which may include ducting, grow lights, and a carbon filter or silencer, among others (where necessary). All of these factors might have an impact on how hard your fan has to work in order to create the ideal growth conditions. For example, any abrupt bends in your ducting will drastically limit the efficiency of the airflow through the system. A 90-degree curve has the potential to restrict airflow by up to 60%!
If you’re using a charcoal filter to eliminate scents emanating from your tent, add additional 60 percent to your calculations.
|Accessories||Effect on CFM|
|LED grow lights||20%|
|HID grow lights||50%|
|Ducting 30º Bend||20%|
|Ducting 90º Bend||60%|
If we only had a few bends, a few LED grow lights, and a CO2 filter, we’d be in business. In the end, our CFM formula would be: 108 (base) * 1.2 (lights) * 1.6 (filter) * 1.9 (ducting) = 394 Total CFM Required You will now need to purchase an exhaust fan that can produce this amount of Cubic Feet of air per Minute, depending on the size of your grow tent and the accessories you will be using. Check out the greatest 6′′ inline fans that are capable of performing admirably.
Other Air Flow And Ventilation Tips
It is reasonable to expect some noise from your grow tent because it requires a powerful fan to air it. It is possible to reduce this so that your growth is more subtle and unobtrusive, but it is not recommended. Choose a fan with variable speed settings and a CFM rating that is 25 percent more than your requirements; this will allow you to run it at a reduced speed and so reduce noise.
Furthermore, the majority of inline fan types are equipped with noise-reducing capabilities. However, as previously said, you may also connect a silencer to your fan, which will reduce the noise it makes.
CO2 Injection To Increase Yields
Injection of CO2 into a grow tent Plants, as most growers are aware, “breathe out” oxygen while “absorbing” Carbon Dioxide (CO2). While plants do not have lungs, they do have hundreds of small holes on their surfaces known as stomata, which allow them to collect CO2 from the surrounding environment. In contrast to us, they require more carbon dioxide in the air than oxygen in order to maintain optimum health. This invisible gas is essential to the process of photosynthesis, and your plants will “suffocate” and die if they do not receive enough of it.
- It may even be possible to make your plants more resistant to heat and light by doing so.
- Trying to get the most out of every situation.
- Even novices and enthusiasts may get incredible yields in the absence of this.

Grow Room Air Conditioner
Despite the fact that it may be deemed unnecessary, an air conditioner may be a worthwhile purchase if you are coping with extreme heat. This is especially true for larger venues. It might be an excellent method of avoiding excessive heat and exerting the greatest amount of control over your temperature. Whether you’re growing in the heat of summer or the cold of winter, your plants will benefit from the right cool breeze and provide you with strong and consistent harvests. You have the option of putting your air conditioning unit on the ground.
It’s also a good idea to put it near an outlet so that any remaining water can be easily drained.
According to this calculator, 5,000 BTU is sufficient for grow tents measuring up to 4x4x8 feet in size.
In conclusion, ventilation is extremely crucial to the health and production of your plants, as you can see. The more the degree to which airflow is left to chance, the greater the likelihood that you will be disappointed with poor yields. There are several methods through which you may exercise control over the ventilation of your grow tent in order to achieve maximum yields. Hopefully, you were able to choose one that best meets your needs. And remember to go back to this post anytime you have any questions.
