  1. This series offers you with the option to track the growth of your produce. Providing the greatest possible environment for your clone and seedlings. You may change the environment to suit your plant’s needs. You may upgrade your clone tent with a fan and a filter as an added bonus.

Consider the fact that if you do not resolve all of these concerns, your entire grow system may come to a complete and total collapse.

What’s The1 Problem?

As you can see, your plants are already enclosed in a protective habitat. As a result, you must ensure that they have access to sufficient fresh air that has the appropriate levels of CO2 (for breathing in) and moisture (for transpiring out), as well as the appropriate temperature (to strengthen stems). The fact that you have to handle it all from the confines of that same, closed space appears to be the biggest concern. It is necessary to exhaust and intake air to ensure appropriate air circulation throughout the tent in order for it to function properly.

Aside from this, there are a number of additional obstacles that may arise along your path.

  1. The accumulation of odors across the area
  2. The accumulation of heat throughout the room The presence of moisture and mold growth on the walls
  3. The air around the tent is too humid to allow the plants to transpire

7 Must-to-follow Tips for A Healthy In-room Venting

The accumulation of odors across the area; the accumulation of heat throughout the room. Mold growth on the walls as a result of excessive moisture. A lack of oxygen in the air around the tent because to excessive humidity.

Tip 1 of 7: Make Sure the Room is Large Enough

The accumulation of odors across the area; the accumulation of heat throughout the room; Moisture and mold growth on the walls; The air around the tent is too humid for the plants to be able to transpire;

Tip 2 of 7: Find the Best Passive VentingOption

There is absolutely no way that your grow tent would be able to pull in fresh air if it did not have any sort of passive exhaust system in place. Because you are unable to guide the exhaust air outdoors, you must find a way to do it in an indirect manner. Here are a few alternatives to consider:

Vent Grow Tent Out Window

The most effective method of releasing used air is through a window. However, in the majority of cases, you will not have this option. Reasons? You might want to keep your hidden pastime a secret from your neighbors, for obvious reasons. Alternatively, you could not have any windows at all, which is especially true if you’re working in the basement. However, if you’re fortunate enough to have a window, you may run ducting from the grow tent exhaust to the window to help with the ventilation. Make careful not to simply use the air pressure to vent it, but to also use a fan to help with the ventilation.

Duct out to A Different Room

In the event that you do not have a window, the next best choice is to exhaust the air through another room. It may be the room next to it, or it could even be the bathroom next door. In either situation, you’ll need to construct a ducting system to connect the tent exhaust to the opposite door or room. Thus, there will be a large reduction in the amount of air that flows through the duct.

In order to overcome this difficulty, install a fan at the far end of the vent that is at least 1.5 times as strong as the tent’s exhaust fan. This will ensure that air flow is continuous and consistent throughout the ducting system.

Try Venting Grow Tent into Attic/Chimney

Many farmers believe it to be a viable choice for venting their plants. However, there is a possibility that some significant complications will arise. First and foremost, there’s the odor to contend with. Because the air will be forced to flow through the whole roof, the foul odor will be able to bother everyone in the residence. Solution: Using a decent carbon filter at the beginning and end of the grow tent exhaust is a simple and effective way to solve the problem quickly and effectively.

Due to the fact that the attic exhausts air from the whole home (including the kitchen), there is always some heat in there.

Alternatively, you may divert the issue to a vent that exits your attic to resolve the problem completely.

Tip 3 of 7: Keep the Exhaust-Intake Holes At Opposite Positions

No matter how hard you try, some warm air from the exhaust system will remain in the room despite your efforts to eliminate it. You may avoid having your plants breathe it over and over again by using a simple workaround. As you are aware, warm air is more likely to be found in the top portion of the room due to the high light density in the upper section of the room. As a result, the air at the ground level will be significantly colder. As a result, be certain that your exhaust system is located at the very top of your tent.

Fortunately, the majority of high-quality tents are designed with this precise configuration in mind.

Tip 4 of 7: Use An AC Unit for the Room

Many of your troubles will be resolved if you install an air conditioning unit in the room where your grow tent is located. In these instances, a mini-split air conditioner is suggested over a window air conditioner or a split air conditioner. Here are some of the advantages of having a high-quality micro split air conditioner in your room:

It’ll Keep The Temperature Down

Consider the fact that temperature build-up is one of the difficulties associated with venting inside the same room. An air conditioning unit, on the other hand, may be able to help in this situation.

It can Dehumidify Your Room(for A Price)

In air conditioning equipment, there is a section where condensation forms on a coil when the system is being operated. As a result, it will draw moisture from the air and channel it into a drainage system. You must, however, maintain a close check on the air to ensure that it does not get excessively dry.

It Keeps Supplying New Air

Although air conditioners are unable to remove stale air, they may certainly bring in fresh air.

And that’s a nice bonus when you’re having trouble venting the tent when you’re in the same room with it. If you are unable to bring in fresh, new air from other locations, the air conditioner can help you address the situation.

Tip 5 of 7: Don’t Rely on Passive Venting

You would believe that simply opening the door would be sufficient to remove the exhaust air from the room. This is not always the case. However, that was a pure coincidence! As a result of the high temperature of the exhaust air, they are more likely to become attached to the ceiling of the room. It will completely derail your entire strategy unless and until you have an active exhaust system for the grow tent ventilation system in place to drain them out completely. It is sufficient to run ducting till the window or door, attic, or chimney, and then direct the exhaust air out through these openings.

Tip 6 of 7: Use A Premium Carbon Filter

We are all aware of the need of a carbon filter in a growing system. However, when you’re venting into the same room as the source of the problem, the need of these filters increases even more. This is due to the fact that coal dust may be recirculated around the grow area/room in such circumstances, which is detrimental to both the air and the plants. Spend a little more money on a carbon filter of superior quality. Investigate and discover filters that include Australian activated coal by conducting a little study.

Tip 7 of 7: Set the System Right for the Light/Dark Cycles

The likelihood of plants transpiring increases when there is darkness. Moreover, they carry out photosynthesis during the light-dark cycle. Additionally, while the lights are on, the building of heat is more frequent. Furthermore, when the dark cycle is activated, the accumulation of humidity is more regular. This means that understanding what your air circulation/temperature/humidity should be throughout these two periods is critical. Because the intake air is coming from the same room as the exhaust air, you should keep these considerations in mind.

Possible Issues and Remedies

Even if you’ve been successful in restoring stability to the entire system, there are still a few things that you need to keep an eye on. Here is a list of potential problems and their solutions:

CO2 Filter Not Working

It is possible that the carbon filter is not actively operating at all times. This means that the exhaust air will not be completely devoid of odors. The causes for this might be one of two types:

  1. The activated carbon has reached saturation. Despite the fact that the activated carbon is not saturated, it is unable to function.


When it comes to the first scenario, there is no other option except changing the carbon filter or fabricating a new carbon filter. Before you do that, you need find out how long your carbon filter will last you. In the second scenario, it’s possible that the humidity in the air was the one who shut off the carbons’ ability to conduct electricity. Dehumidifiers placed inside the tent would be the best solution in those situations.

Mold Buildup on Wall

Over time, repeated venting into the same area can cause the wall of the room to get moist, allowing mold to grow on it. This is considerably more likely to occur if your walls do not have adequate protective coatings applied to prevent corrosion.


There is no other option other than to separate the wall from the damp air. You might try utilizing a whole-house dehumidifier to ensure that the air is sufficiently dry. Additionally, some air conditioners are equipped with a built-in dehumidifier, which may be beneficial.

Whether you are venting via those small holes in the wall, you should check to see if this is the case. Because the purpose of these holes is to preserve the wall cavities rather than to exhaust moist air from within the room.

Imbalanced Cooling/Heating

When you’re utilizing a mini-split air conditioner to cool down the room where the tent is placed, the cooling should be adjusted to match the amount of heat that is emitted by the tent. Otherwise, an uneven heating-cooling ratio will result in an air system that is either excessively humid or too dry.


To determine the heat, you may take the temperature inside the tent and reduce it by 5-6 degrees Celsius to the temperature outside the tent. It will ensure that the supply of cold air is maintained. Another point to remember is that wattage is the same whether the light is LED or HPS. As long as the wattage is the same, both LEDs and high-pressure sodium lamps (HPS) will generate the same amount of heat.

Quick Grow Tent Ventilation Tips Before We Finish

  • Keep a close watch out for any changes in temperature. The use of inexpensive thermometers will suffice
  • In the event that you are successful in connecting the room to central heat and air conditioning, this will alleviate a great deal of your concerns. For as long as you are able, keep the doors and windows (if any) open. Do not use the little vents on the wall of the room to vent your air. Mold can accumulate in the wall cavities if they are not installed properly. During the summer, pay more attention to the overall condition of the ventilation system. Summer, in comparison to winter, provides higher temperatures and higher humidity to any air conditioning system.

4 Expert Tips for Venting Grow Tent Into Same Room

Because I am an Amazon Associate, I receive money when people make eligible purchases. You will not be charged any additional fees! Any plant will grow in the presence of fresh air and breeze, which is something that occurs naturally in the wild. When you cultivate your plants indoors, you must provide the right climate for them. It is not something that happens automatically. The air circulation in your home may be controlled with the help of exhaust and venting systems. When venting your grow tent, you have the option of venting it outside or in the same room where your grow tents have been put.

In this post, we’ll provide you some pointers on how to get ideal and healthy in-room ventilation.

But first, let’s take a look at why it’s crucial to have proper air circulation in your grow tent in the first place.

Benefits of Good Air Circulation In Your Grow Tent

A grow tent or chamber is a closed environment that does not allow for the passage of wind to occur. Plants may suffer from a lack of air circulation if they are not provided with enough ventilation. Your plants will not grow and flourish in the same way as plants planted in an open environment with a constant flow of fresh air would grow and thrive. Ventilating your grow room ensures that the plant grows in the greatest possible atmosphere. It provides the wind and air that the plant need for a variety of purposes.

  • Grow tents and rooms are enclosed environments that do not allow for the passage of wind to circulate. Plants may suffer from a lack of air circulation if they are not properly ventilated and maintained. If your plants are not cultivated in an open location with a constant flow of fresh air, they will not grow and thrive as well as ones that are. It is important to ventilate your grow area so that your plants may flourish. For a variety of reasons, it provides the wind and air required by the plant. Following is a list of the most significant advantages of continually venting your grow tent.

Preventing bud rot, mould and white Powdery Mildew

This occurs when air passes through the leaves of a plant and removes the moisture that has been produced by the plant during transpiration. Increased water and nutrient absorption by the plant is enabled as a result of this. The removal of moisture from a plant by air blowing reduces the likelihood of the plant decaying or developing mould on it. Pests are being reduced. Pests such as spider mites and gnats are unable to grow in a windy environment. They are readily blown away by the air. They prefer to live in dry soils where there is no wind blowing through them.

Controlling the Humidity and Temperature Air circulation aids in the uniform distribution of heat and water vapour throughout the growth region.

Strengthening of the stem An effervescent breeze sways and wiggles the branches of your plant, just like in the wild.

This aids the plant in its efforts to gain vigor over time. When the plant begins to blossom and put more weight on its leaves, the strength of the branches becomes increasingly important.

4 Expert Tips for Venting Grow Tent Into Same Room

When you vent your grow tent in the same room as your grow room, the following suggestions will help you get the most out of your investment.

1. Place Your Grow Tent in A Large Room

If you want to vent your grow tent into the same room, be sure the area is large enough to accommodate the humid and hot air that will be coming from your growing environment. It will be difficult to tell the difference when venting in a large space. The air that has been removed from your grow tent will naturally depart from your room. When you open the windows, the fog will simply dissipate. The room becomes stuffy if you vent a grow room into a compact space, on the other hand. In the majority of circumstances, choose a space that is not currently in use.

2. Air Condition Your Room

onehourairftworth.com is the source of this information. The most important guideline for in-room venting is to make certain that the air in the room is properly condition. If you do not condition the air, you will be forced to vent from the grow tent, where the same air will find its way back into the grow tent. Another disadvantage of not air conditioning your room is that it becomes extremely hot and stuffy. The humidity in the room will also increase, which will lead to the growth of diseases such as mould and fungi.

  1. You will also make certain that the space has enough of fresh air, which will be beneficial to the grow room.

Best Ways to Discreetly Exhaust Your Grow Tent

While grow tentkits are included with comprehensive assembly instructions, you will still be need to make important decisions about where they will be placed in your house. When attempting to determine the best location for a grow tent, the convenience of usage, garden security, and tent exhaust alternatives should be your key concerns. Figuring out where to vent your grow tent may be quite difficult, especially for first-time farmers. While tent manufacturers have created incredible technology for use within tents, there is little information available on how to properly position your exhaust outside of the tent’s setup.

Grow Tent Exhaust System Basics

Grow tentkits come with comprehensive assembly instructions, but the final decision on where and how to place them in your house is up to you and your creativity. When attempting to determine the best location for a grow tent, the convenience of usage, garden security, and tent exhaust alternatives should be your key concerns. For new growers, determining where to vent your grow tent might be a difficult task to complete successfully. In spite of the fact that tent manufacturers have created incredible technology for use within tents, there is little advice available on how to position your exhaust outside of the tent setup.

Use Existing Outdoor Vents

For the most majority of experiencedindoor producers, pre-existing external vents are the preferred technique of draining a growroom or tent after harvest. Not only are these vents intended for the goal of directing air to the exterior of your property, but you are unlikely to have to undertake any big modifications in order to get access to or install them. Even better, outdoor vents are exceedingly unobtrusive and safe to install.

Laundry Room

If you have enough space, the laundry room is one of the greatest places to set up a grow tent for cannabis cultivation. Apart from having built-in exhaust vents that lead to the outside, these facilities also have water connections and electrical outlets to make life easier. If you want to make the most of your laundry room vent, you may place your ducting such that air is forced directly out the vent that was designed for your dyer. This will almost certainly need the use of a ducting boot that is the same size as your ducting and the vent.

The second solution may also necessitate the installation of a booster fan and a shutter to guarantee that hot air from the dryer does not enter your grow tent.


“Passive vents” are found in areas of your home that are not climate-controlled, such as attics and garages. If you didn’t already know, passive ventilation is the process of exchanging old air for new air without the need of any mechanical devices. It is possible that you have passive vents in your attic or garage if you have seen vents that are exposed to the outside straight from the inside. You have two alternatives when it comes to utilizing passive vents. The first advantage is that you can set up your grow tent in either of these locations and have it exhaust straight through a passive vent.

For the second option, you may make a hole in a wall or ceiling and direct the exhaust from the tent into a garage or attic.

For a garage or attic to be a successful exhausting place, you must guarantee that there is sufficient air movement through these spaces.

You may improve air exchange by adding a simple booster fan to your passive vents, which will help prevent mold growth and excessive heat build-up in your home. When it comes to transporting air out of garages and attics, AC Infinity Airlift Shutter Exhaust Fans are excellent choices.

Different Window Setups

‘Passive vents’ are used in areas of your property that are not climate-controlled, such as attics and garages. For those who are unfamiliar with the term, passive ventilation is a method of exchanging old and new air without the need of any mechanical equipment. In your attic or garage, you may have seen vents that open straight to the outdoors. These are passive vents, and you may have noticed them before. There are two ways for utilizing passive vents. If you want to start with, you may set up your grow tent in either of these locations and send the exhaust through a passive vent.

For the second option, you may drill a hole in a wall or ceiling and direct the exhaust from the tent into your garage or attic space.

For a garage or attic to be a successful exhausting place, you must first guarantee that adequate air is circulating through these spaces.

For venting air out of garages and attics, AC Infinity Airlift Shutter Exhaust Fans are excellent choices.

Window Vent Kits

Window vent kits, which are meant for portable air conditioners, are used by some tent growers to ventilate their cannabis gardens. Not only are these kits widely accessible on places such as Amazon, but they are also particularly designed to function with ducting. Even more, window vent kits are unlikely to attract attention because they are often utilized to exhaust hot air from air conditioning systems.

Boarded Windows

Cutting a piece of plywood to the size of the chosen window and painting it black is how you go about creating a boarded window. Open the window approximately 6-inches and attach the black piece of plywood to the whole window frame, covering the entire window frame. Finally, drill a circular hole into the piece of wood that is the same size as your ducting. This hole will serve as a vent for your home. This configuration enables you to position your grow tent near a window without experiencing significant noise leakage.

  • Summary The use of grow tents for indoor cannabis growing is a handy and cost-effective choice.
  • When you take into consideration the many exhaust choices, this concept becomes more complicated and difficult to grasp.
  • They are not only intended to move air, but they also serve to keep your garden safe from intruders who may come in via the open windows.
  • AC Infinity is the most recognized name in air delivery systems, having designed and developed the most cutting-edge breakthroughs in cooling and ventilation technology throughout the years.

They provide a range of inline fans that are both silent and efficient, and which automate the growth process and track crucial data. For additional information, please see www.acinfinity.com or contact us.

Do I need to vent my grow tent outside?

Asked in the following category: General The most recent update was made on May 1, 2020. Make certain that your ducting is the correct size for your grow tent. In order to expel hot air from the grow tent, outside ducting will need to be connected to an exhaust fan window. It is also critical to ensure adequate ventilation within the grow tent. Clip-on fans or an oscillating fan are all that are required to generate a gentle artificial breeze in your home. It is not required to exhaust the air that is being drawn through the carbon filter outside of the growing area; in fact, depending on your setup, it may even be preferable to return the filtered air to the growth area as soon as it is brought through the filter.

The primary issue is the heat generated by the LEDlight, as well as the accumulation of heat in such a small confined space.

Make certain that your grow tent is well ventilated in order to avoid these typical difficulties as much as possible.

Here’s what you need to do (it’s simple):

  1. Install your grow tent, complete with a grow light inside
  2. Install the exhaust fan at the very top of your tent, so that it is blowing air out of the tent. Make certain that there is an intake opening for fresh air to enter
  3. Install a window fan that blows air out of the room where the tent is located.

Is it necessary to use a carbon filter in a grow tent? The use of activated carbon filters in grow tents and growrooms is widespread because they are effective in reducing smells and controlling emissions. In the end, you will have cleaner air that is free of odors, spores, and other allergies. Odors and emissions have an impact on how pleasant your house is to live in; they may be uncomfortable at the very least and potentially dangerous at the very worst.

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

Extraction fans, also known as extractor fans, are used to exhaust hot and humid air from within a grow room or tent. They are also known as extraction fans. Slight variations in temperature and humidity can have a significant impact on your ability to produce a profitable harvest. Furthermore, unmanaged heat and humidity cause poor growth conditions, resulting in your plants being unable to absorb water or simply failing to make it through the season. The use of an inline duct fan in your grow room is essential for controlling the environment in your growing area.

You can manage the inside temperature more effectively by using an active exhaust fan to draw in colder air.

In passive intake ventilation systems, inline duct fans also function as a vacuum, drawing in new CO2 from the outside air.

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.

What Size Inline Fan do I Need?

In order to provide airflow into your grow environment, there are several configurations for these components. 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 motor. If air is being drawn out of your grow room, you can place them in whatever sequence you like inside the ventilation chain. The configuration of your ventilation system may be customized in at least four different ways to meet your specific requirements.

The fan and/or filter may be placed outside of the grow tent in this situation.

Because heat rises to the top of the building, draining the hot air from the top of the building will make the ventilation process more productive. Positioning your carbon filter at the highest place will also improve its performance.

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.
  • 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. You may also choose to use insulated ducting instead of regular ducting to lessen the whooshing wind noise that occurs during the installation.

However, you will want to consider whether or not there are any possibilities for vent expanding into the exact same room.

Are you interested in knowing what they are?

As a result, continue reading to learn about the 7 strategies for same room vent growth, as well as the troubles that they would resolve.

What are common issues with the same room vent growing?

Know that a growing system is simply one that has both exhaust and intake ports, which allows it to both feed new air into the environment and exhaust the heated air or exhaust that results from the process. As a result, the heated exhaust air is prevented from accumulating all around your tent, and the fresh new air is prevented from entering. As a result, you must continue to provide the tent with fresh, chilly air. However, there is a problem, and that problem is that it is difficult to achieve all of the above requirements if your entire system is contained within a single room.

  1. Without doing so, you will find yourself in a situation where drilling through your walls is not an option for you.
  2. But that’s not all there is to it.
  3. It’s also probable that you’ll have to deal with mildew and wetness on your walls as a result of this situation.
  4. As a result, it is imperative that a solution be found.

What is the main issue that we need to be targeting in all our solutions?

Before we can go on to finding a solution, we must first identify the one key issue that we should be focusing on, which is providing your plants with a continuous fresh air supply so that they can receive a continuous fresh air supply that is rich in CO2. However, this isn’t enough in and of itself. You must also make certain that the air is at the proper temperature and has the appropriate amount of moisture. It’s also worth mentioning that you’ll have to deal with the issue of appropriate air circulation throughout the entire grow tentas as well.

As a result, you must exhaust all of the completely vented air while still maintaining a continuous flow of fresh air.

7 tried-and-tested tips for same room venting

Note that if you don’t have any type of exhaust system, not even a passive one, your tent will not be able to obtain any fresh air since it will not be able to breathe. However, there are still choices that you will be able to investigate more. You can, for example, open a window to let the humid and hot air out and cool off.

However, if you are growing in your basement, it is possible that there are no windows available. If you do have a window, though, you need construct a tunnel leading from the tent to the window. Don’t forget to utilize a fan instead of simply venting it through the air pressure.

2. Create a duct to another room

It’s important to note that if you don’t have any sort of exhaust system, not even a passive one, your tent will be unable to get any fresh air. However, you will still have a number of alternatives to choose from. In order to vent away the humid and hot air, you can open a window, for instance. It is possible, though, that there will be no windows in your basement if you are growing in it. If you do have a window, though, you need construct a tunnel leading from your tent to your window. To ensure proper ventilation, make use of a fan rather than simply relying on air pressure.

3. Vent in a large room

If you intend to vent inside the same room, you will need to make sure that there is plenty of space available. This is due to the fact that hot air will constantly accumulate in that area. Consequently, if the room is large enough, there will be enough space for this humid and hot air to at the very least be isolated from the comparatively chilly air present at the bottom of the room. But the question is, how much space do you require for your room to function properly? There isn’t a single, straightforward solution to this problem.

The basement room is the finest alternative if you’re considering which room to employ for this function.

You will, however, require a tiny system with a single or a single plant in order to accomplish this.

To do this, you can make use of whatever type of inexpensive thermometer you like.

4. Vent into your chimney

Many people choose to vent up a chimney or even an attic as an alternative. However, you must be aware of the fact that there will be a scent if you choose to go this route. After all, because the air will be going throughout your whole ceiling, the foul stench that will emanate from there will be able to offend virtually everyone who is there in your home. Not to mention the possibility of mold growing in your attic due to the fact that your attic or chimney will be venting your entire house.

However, the good news is that both of these problems can be resolved.

This will address the problem in a short period of time.

This will, without a doubt, prevent the accumulation of heat and humidity.

5. Put your exhaust and intake holes right at very opposite positions

It’s important to realize that there will always be a little amount of heated air escaping from your exhaust system. Even that, though, is a source of concern, since your pants will in fact be perspiring all over themselves. However, there is a solution to this problem, and that answer is provided by an exhaust system. Remember that because warm air is lighter than cold air, it will be present in the upper regions or areas of your body as well.

As a result, your floor part will be significantly colder than the rest of the house. As a result, you must locate your whole exhaust system directly above the top of your tent, and then locate the specified intake hole directly below the bottom of your tent.

6. Make use of a good carbon filter

It is important to understand that while using the same room venting, there is an issue with the coal dust being cycled and then recirculated all over the room. This is detrimental to the plants, which will unavoidably be harmed as a result of this. Carbon filters, on the other hand, can be beneficial in this situation since they can filter out all of the coal dust. It is important to note that when purchasing carbon filters, you should ensure that they are of high quality so that you can be confident that your plants are developing properly.

7. Buy an AC for your room

If you can just place an air conditioner in the room where the grow tent is being stored, you will be able to resolve a slew of concerns relating to adequate air circulation in your home. If you do decide to get an air conditioner, go for a mini-split model rather than a split or a window model. It is important to note that if you install an air conditioner, the room temperature will be reduced, and the room will also be dehumidified. You should, however, be on the alert for dry air, which can be harmful to your plants if it exists.

The machine will introduce new and fresh air into the space while removing the old and stale air from it.

As a result of this, heat and humidity tend to collect, which has a detrimental impact on the plants’ growth.


Exhaust from your grow tent may be sent outside your home or into a separate room using ducting. You may also choose to vent it into the same room where you have the tent set up if you like. The second approach is significantly more convenient since it removes the inconvenience of venting outside your house.

How to vent a grow room?

Simply exhausting the humid air with the aid of an exhaust system is all that is required. You may also install a dehumidifier if the situation calls for it. It is possible that you may need to raise the humidity level from time to time throughout the growth process.

Should I leave a vent open in the grow room?

Ensure that the intake vents in your grow tent are fully operational if you are utilizing passive intake technology. At the same time, you should leave a window open near your grow tent to allow for ventilation. This will assist in replacing the heated air that is escaping from your tent. If you are utilizing active intake, on the other hand, you should put your intake fan near the intake vent of your grow tent.

Why should you opt for passive venting?

The absence of an exhaust system means that your tent will be deprived of any opportunity to obtain some fresh air. You may, on the other hand, open your windows and let the hot and humid air go.

How important is airflow in a grow room?

Proper ventilation in the grow room is critical to the success of the operation. This is due to the fact that it inhibits mold, mildew, pests, and illnesses from establishing root in the home.

Make sure to arrange the airflow and ventilation system of the grow room before you begin planting any trees. You can naturally alleviate many of the challenges associated with indoor gardening by using the greatest circulation fans available.

How do you vent a grow room without windows?

In the event that your grow room does not have windows, you might exhaust the air through a separate room in the house. It is possible to vent the air out of the room next door, which is what we are referring to. A ducting system connecting the tent exhaust to the adjacent room will be required in this situation.

How often should you vent your grow tent?

Your grow tent must be exchanged at least once every 5 minutes to ensure proper air circulation. If you are utilizing a grow tent that is 5′ x 5′ x 6′, you will have 150 sq/ft of available space. You’ll need a fan and filter that can move between 30 and 60 cubic feet per minute (CFM) to ensure appropriate airflow. Aside from that, you must maintain a balance between the air that comes in and the air that leaves.
