How To Make A Grow Tent Smell Proof

3 Ways To Smell Proof Grow Tent

Your cannabis plants are at the blooming stage if they have lush, big, crystal-like resin-covered buds on their stems. While this is fantastic news for your crops, the distinct stench that comes along with it may be a source of concern for some. This has the potential to be a fascinating and gratifying experience for indoor growers. The scent is passable, if not downright pleasant. Nonetheless, odor control is essential, particularly if the situation becomes bothersome for your neighbors. Most of the time, utilizing a carbon filter, you can either mask the odor or scrape it away completely out of the air.

It all boils down to finding the most effective method of controlling it.

We’ve also included several low-cost alternatives to the traditional techniques of odor-proofing grow tents.

You may use any one of them or a combination of them to create a worry-free marijuana growing environment.

Why not have it both ways?

Where Does the Smell Come From?

It is because they have not generated terpenes, which are the chemicals responsible for the aromatic qualities of a marijuana plant, that cannabis plants in their vegetative stage have a very faint odour. When a weed plant enters the blooming phase and begins to create flowering nodes, it will begin to grow trichomes on its leaves and stems. It is the trichomes which are the molecular factories which produce a large number of aromatic chemicals.

What Strengthens Odor in a Marijuana Grow Room?

If the stink is not managed, it will linger in the air, ultimately infiltrating the whole grow room.

Humidity Levels and Temperature

In a grow room, high humidity and warmth might help to keep the cannabis fragrance going longer. As a result, the first thing to evaluate is whether or not you have the right temperature and relative humidity settings. Certain strains may have specific requirements, however the following are the ideal humidity levels during the different stages of marijuana cultivation.

  • Moisture content during the cloning phase ranges from 70 to 80 percent
  • During the vegetative phase ranges from 40 to 60 percent humidity
  • During the flowering phase ranges from 40 to 50 percent humidity
  • During the last weeks of the flowering phase ranges from less than 40 percent humidity.

During the transition and growth stages of your weed plants, you must be aware of maintaining temperature and humidity regulation. This may be accomplished through the use of air conditioners and dehumidifiers.

Proper air circulation is important

Proper air circulation in a grow environment is important for keeping the temperature and cannabis odor at a manageable level. Additionally, it has the capability of recycling wasted CO2 from your grow room. As a result, ensuring that your grow room has adequate air circulation helps to maintain the proper temperature and relative humidity. Heat is emitted by grow lights in varying degrees of intensity. Hotter systems, such as ceramic metal halide (CMH) and high intensity discharge (HID), may have a more difficult time keeping the heat under control.

If there is insufficient air movement and ventilation, all growth illumination systems have the potential to generate dangerously high temperatures.

In order to provide enough air circulation, installing either standing or oscillating fans is the most practical option. When fans are used in conjunction with ducted intake and exhaust fans, it becomes simpler for the air to circulate, therefore removing the scent from the room.

Effective Solutions in Controlling Odor in a Marijuana Grow Room

In order to maintain optimal grow room odor management, With only one or two plants in a tiny grow tent, it’s very feasible to completely eliminate the odor from the environment. However, if you have a larger grow space, you will almost certainly need to cleanse the fragrance from the air. Here are the most effective strategies for eliminating odors from a grow room or tent, which any grower can confirm to using them. Without much effort, I’m confident you will find the best option for your particular situation through experimenting.

1. Install Carbon Filters or Scrubber in the Exhaust System

As previously said, it is hard to completely eliminate the aroma, but an air filter with activated charcoal may effectively eliminate 90 percent of the cannabis odor in your grow environment. In order to remove impurities from the air, carbon filters generate activated and highly ionized carbon, which draws particles from the air and draws them into the filter’s chamber. A pre-filter is used to keep odor-causing volatile organic substances such as mold spores, dust, and hair contained in a pre-filter.

After the filter removes odor molecules from the air, you are left with clean, fresh air that does not contain any odor molecules.

Here’s a fun fact

Carbon scrubbing surroundings may reduce the number of airborne germs in your marijuana grow room from a stunning 10,000 parts per million to as low as 30 parts per million, depending on the environment. Furthermore, employing a carbon filter to manage odor in a marijuana grow room is the most ecologically friendly method of odor control available on the market. It is important to note that carbon filters can range in size from 4 to 12 inches in circumference. The cubic feet per minute of your marijuana grow space must be determined first before you can estimate the size of carbon filters you will require.

For example, you have a44grow space that is 4 x 4 x 6.5=104 square feet.

  • It is possible to reduce airborne bacterial counts in your marijuana grow room from a stunning 10,000 parts per million to as low as 30 parts per million when using carbon cleansed conditions. Aside from that, utilizing a carbon filter to manage the smell in a marijuana grow room is the most ecologically friendly method of controlling odor. Remember that carbon filters can range in diameter from 4 to 12 inches. The cubic feet per minute of your marijuana grow space must be determined before you can decide what size carbon filters you need. To calculate this, multiply the length, breadth, and height by three and you have your answer. You have a44grow space, which measures 4 x 4 x 6=104 square feet. CFMHere’s a table defining the suitable carbon filter sizes based on the average cubic feet per minute they can produce. (CFM).

How to Set Up a Carbon Filter for Ideal Odor Control

Taking a look at the table, we can see that a 4-inch carbon filter may be utilized. Another example is shown below. The fan and filter in your cannabis grow room should be able to handle 100 CFM in order to cover 500 square feet in 5 minutes if your grow area has a square footage of 500 square feet. As a result, you are able to reduce the stink in your grow room by properly replenishing the air in it. As an example, with a 10 x 10 x 12 foot cannabis growing room, you would have 400 as your starting point.

  1. The light temperature should be taken into consideration when utilizing a CMH light, thus it’s preferable to add 15 percent (60) to the formula.
  2. As a result, 400 + 100 + 60 + 80 = 640 CFM.
  3. Make sure that the CFM rating of your filter is higher than that of your fan.
  4. It will also ensure maximum efficiency by just taking in as much air as it is capable of holding, therefore cleansing as much air as it is capable of holding.
  5. Try to maintain the humidity level below 70 percent if your growth conditions allow for it.
  6. However, an inexpensive carbon filter should be effective for a lengthy period of time in controlling the odour in your cannabis grow room.
  7. Keeping in mind what I’ve discussed previously, you can combine the approaches presented in this piece.

If you decide to install a carbon filter, you may complement the filter with an odor-eliminating gel or spray. Consider constructing your ownDIY carbon filter as an alternative, especially if you are on a tight budget and have some basic DIY skills.

2. Use Inline Fans

The use of an inline fan improves the efficacy of a carbon filter by several factors. The fans are responsible for removing excess carbon dioxide from the atmosphere and regulating the ecosystem. In a similar way as scrubbers, the CFM calculates the appropriate inline fan to use to manage the smell and odor in your marijuana grow room or tent. In order to choose the best inline fan with the appropriate CFM capacity, multiply the following factors by 1.25: the length, width, and height (in feet) of your grow space (125 percent ).

  1. It should be the quantity of air that your inline fan is capable of expelling in a single minute from the system.
  2. As a result of this calculation, an air conditioner with a capacity of 260 CFM will exchange 260 cubic feet of air per minute.
  3. So you will have better control over the stench in your marijuana grow room as a result of this.
  4. In addition, the noisier versions are often the more affordable types.
  5. The most commonly used fan has a 6-inch diameter.
  6. Don’t forget to correctly install the fan so that it may work as a vacuum within your cannabis growing environment.

3. Consider Odor Cover-Ups or Neutralizers

During the latter six weeks of a marijuana plant’s lifetime, dealing with the stench gets significantly more difficult. Using odor cover-ups is the most effective method of acquiring additional protection. Trichomes produce the largest concentration of terpenes during these two weeks of development. Even in the presence of adequate air circulation and ventilation, the presence of a high concentration of cannabis scent in the air indicates a problem. As a result, it’s advisable to boost up your odor management tactics by incorporating odor absorption gels into your arsenal.

To be clear, absorbent gels can literally disguise the scent, but they will not be able to completely eliminate it from your marijuana grow environment.

Absorbing gels, on the other hand, should not be used in a grow room since the fragrance of the gel will be absorbed by your marijuana plants.

As a result, odor neutralizers should only be used in moderation.

Gels are typically packaged with a cover, which means you only have to open it when necessary. Because odor neutralizers are only effective for a few of hours at a time, you may consider this a last resort choice in an emergency situation.

Can Air Purifiers Remove Odor in a Marijuana Grow Room?

Recall how I stated that even the most effective carbon filters could not completely erase the odor from the air? Air purifiers, on the other hand, will be unable to do this. We are all aware of how effective air purifiers are in removing dust and allergens from the air that circulates in our homes. But they are not powerful enough to mask the distinct scent of blossoming marijuana, which may be overwhelming.

Should I Use an Ozone Generator to Mask the Smell in a Weed Grow Space?

The short answer is no. Back in the day, when indoor farming was done using outdated equipment, ozone generators were quite effective at eradicating the smell of cannabis from a grow tent. Unfortunately, it can only be utilized if there are no humans or animals in the immediate vicinity of the device. That demonstrates how hazardous the ozone machine may be. Ozone is classified as a serious indoor air pollutant, which means that when breathed, it may be harmful to the lungs. Similar to this, prolonged exposure to high quantities of ozone can result in lung illness.

Furthermore, the Environmental Protection Agency does not suggest using the equipment.

Key Takeaways

While growing indoor marijuana may be a rewarding experience, keep in mind that the odour may not be pleasant to everyone, especially those in your immediate vicinity. Using one of our suggested strategies, or a combination of many of them, is an investment that is worthwhile. When it comes to indoor gardening, the units we’ve created are very necessary. Your marijuana grow room should be temperature regulated and well aired. It should also be fitted with a carbon filter exhaust and fans, which will help to remove almost 100 percent of the odor.

  • Please keep in mind that eliminating all airborne particles will result in unhealthful air in your growing environment.
  • Take use of these time-tested methods to combat the scent and ensure that you don’t let the odor prevent you from growing high-quality marijuana in your grow room!
  • She contributes to a variety of online media and websites.
  • With significant expertise in both hydroponics and aquaponics, she is well-versed in the art of indoor growing.

Are Grow Tents Smell Proof?

Privacy is important to grow tent users at all stages of the growing process, including the flowering stage and even the process of receiving their grow tent package. It is during the first of these periods, however, that maintaining privacy becomes the most difficult. When growing cannabis, new producers may feel that grow tents are adequate in preventing smells from spreading. However, this is not the case. After all, it is a protective container. At the same time, the enclosure is constructed of fabric and zippers, raising the question of whether or not grow tents are odor-proof.

The materials and components that make up a grow tent system (reflective mylar, tent canvas, inline duct fan, ducting tubes, and so on) do not meet the requirements for being smell proof.

A properly routed ducting system will vent smells away from the developing system, but it will just send the nasty smell to the outside of the building. So, what are your plans for dealing with it?

Why Your Grow Tent Smells

Cannabis plants generate the foulest scents during the blooming stage, when buds begin to form, although they can begin generating odors as early as three weeks after the flowering stage has begun. During the vegetative stage, the odor is no different from that of other plants, thus there is normally no need to be concerned at this point in time. Terpenes, which are aromatic chemicals that give cannabis its distinctive fragrance, are found in high amounts in the plant’s leaves and flowers. Some strains have stronger odors than others, but they are all distinct in their own way.

As a result, while terpenes are responsible for the unpleasant emissions, they are also responsible for the unique characteristics of the cannabis plant.

How to Deal with Cannabis Odor

The use of a charcoal filter is the most effective method of reducing or eliminating the powerful fragrance of cannabis. This duct attachment functions as a gateway, allowing stale air to pass through while trapping smells within. Inactivated charcoal is used to prevent unpleasant odors by adsorbing odor particles in the micron-sized fissures on the charcoal surface, which are present on the charcoal surface. The larger the pores in the carbon filter, the more efficient and long-lasting the filter will be in the long run.

Consequently, as its efficiency reduces, the carbon filter will not get burdened down.

The use of a carbon filter will result in a significant reduction in the spread of odor.

It also has a lock, which is useful for keeping your stockpile safe and secure.

8.Check Your Ducts for Air Leaks

Maybe a little hole has appeared in your grow space’s ventilation system, which is allowing an excessive amount of cannabis odor to escape. Running soapy water over your ducting and then turning on the fan is one method of checking for leaks. If you notice a bubble-filled area, you’ll know there’s a leak.

9.Grow Low-Odor Cannabis Strains

My prediction is that genetically engineered cannabis strains will be available in the not-too-distant future, resulting in a plant that generates little to no terpenes. Terpenes are the oil generated by the cannabis plant and are responsible for the pungent odor that the plant emits. For the time being, you can experiment with cultivating strains that are known to create less odor than others, however the results will be less than ideal. Maybe it’s just that it’s simpler to handle.

Which cannabis strains are thought to be low-odor?

1.The Northern Lights (also known as the Northern Lights of Canada) (click for details) Northern lights is a strain that is 10 percent sativa and 90 percent indica, and it is a very easy strain to cultivate.

Best Smell Proof Grow Tents 2021: How to smell proof a grow box

In response to photochemical reactivity, plants emit various Volatile Organic Compounds (VOC) during the process of food assimilation, which provide a distinct odor or odor in any growing environment where they are present. Volatile organic compounds are defined as “any compound of carbon, except carbon monoxide, CO2, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, that participates in atmospheric photochemical processes” according to the American Chemical Society.

Where does it come from?

Since growing plants in a controlled setting does not allow these chemicals to escape from the cabin if there is an insufficient system in place to excrete them from the interior environment, this is an important consideration. Volatile Organic Compounds (VOCs) are released by mature plants as part of their physiological process, and it is impossible to prevent them from releasing these compounds when they are mature. The difficulty emerges when this odor remains retained in the growing environment at a low concentration for an extended period of time, and growers detect it using their sense of scent.

An unpleasant odor is produced in a growing environment when air passes over a bed of activated carbon.

It is possible that something will emerge out of the grow tent that is unsightly to our eyes. Selecting the appropriate carbon filter, or growing in an odor-proof grow tent, are two options for dealing with this problem.

Top 7 Smell Proof Grow Tent 2021

Installing a deep carbon bed with extra activated carbon, on the other hand, might easily address the situation. Deep carbon beds are long-lasting and effective in keeping the stench at bay for prolonged periods of time. Also, make certain that the filter and fan that are attached are the same size as the spigot and fan diameter. In addition, odor control in the growing environment may be achieved by utilizing a reducer solution. A smaller carbon filter spigot may obstruct the flow of the fan, as the air must come into close touch with the filter carbon in order to eradicate the odor from the fan motor.

How to smell proof a grow room?

Various ways to managing odors in a grow room are available. However, improving air circulation in a developing environment should be the first order of business. The goal of adequate air circulation is to eliminate CO2 that has been accumulated. An additional consideration is the heat generated by high-intensity grow lights. Plants are capable of adapting to a wide range of temperature and humidity conditions depending on their developmental stage. In order to circulate air in the grow room, it is absolutely necessary to install an oscillating fan at an appropriate spot in the room, which will vary based on the space’s form and makeup.

1 Installing a Carbon Filter

In addition, an activated carbon filter eliminates roughly 90 percent of the odor from the grow chamber. Some types of odors also attract grey mold, spores, dust, and hanging particles, which can result in a fetid environment if left unchecked.

2 Ozone Generator

It also eliminates approximately 90 percent of the scent from the grow room, which is another benefit of using activated carbon filters. In addition, some types of odours attract grey mold, spores, dust, and hanging particles, all of which can contribute to the creation of an odiferous atmosphere.

3 Installing AirSurface Purifiers

In addition, these are some of the most efficient strategies for removing odors and contaminants from the grow room that are suitable for big grow rooms, particularly corporate farming facilities, in order to reduce the degree of smell to a tolerable level.

4 Odor Absorbing Gels

Some growers may find odor absorption gel to be a fantastic odor-controlling choice, but this is not the case for everybody. The reason for this conundrum is that certain gels have an aroma that may or may not be a fragrance for everyone. In any case, the gels are effective in big quantities, and producers report a more pleasant environment following their use. Having a smell-proof grow room helps users to accomplish their growing activities in a more efficient manner.

5 Maintaining Grow Room TemperatureHumidity

The scent of a grow room is directly related to the temperature and humidity in the space. The scent becomes more noticeable during the flowering stage if the humidity level is maintained at the same level as it was during the vegetative stage, which is due to the fact that plants require various amounts of humidity and temperature at different phases of development. Additionally, the greater the temperature of the grow chamber, the higher the humidity and the stronger the fragrance are as well.

It is necessary for growers to reduce humidity by about 50% during the flowering period. When plants are transitioning from the vegetative stage to the blooming stage, it is ideal to maintain both temperature and humidity levels simultaneously.

How to make a smell proof grow box?

Step-by-step instructions on how to construct an odor-proof grow box or a smell-proof grow box, as well as the necessary accessories and tools;

Step 1:

Calculate the appropriate amount of space for your plants based on their requirements before employing the resources at your disposal. To construct a grow box, you will need the following items: a used wooden cabinet; exhaust fans; air ducts; a grow light; Mylar coated sheet; drippers; an inline fan; a thermostat; and the equipment you will require: a drill; a square; a tape measure; a circular saw; a knife; and a tape measure. You won’t have to cut or reposition the wooden cabinet, and you won’t need to drill holes in it to accommodate all of the items you want to store within.

Step 2:

Create two windows on the upper side of the cabinet: one for seeing and another for passing the electrical lines through. You’ll need another hole or a small window to allow you to cross the water line and install drippers.

Step 3:

Install a Mylar sheet on the inside of the cabinet to protect it. It will prevent moisture from entering the cabinet and will reflect light while also keeping the temperature stable throughout the winter. Mylar is not the only inexpensive choice; you can also use Styrofoam or repurposed aluminum foil.

Step 4:

Install the common fans and a thermostat, and set it to operate at the predetermined temperatures in accordance with the needs of the plants in question. You may just use a USB drive, which eliminates the requirement for wiring. Another hole at the base corner for air intake is required, which should be 6′′ from the bottom. Create a second hole in the box, this time in the opposite direction of the first hole, to allow warm air to escape. Two fans were put in opposing directions to each other, one for drawing in fresh air from the outside and throwing it into the box, and the other for throwing air out of the box, both of which were positioned in the same location.

Step 5:

Connect the thermostat to the master control switch in order to regulate the thermostat’s temperature. The thermostat is equipped with a small probe that allows you to connect it to the switch and route the wire via a small hole that you drill towards the bottom of your grow box.

Step 6:

On the ceiling of your grow box, a tiny hole will be required for the passage of a wire for the LED Light. Cut a little more wire so that you can adjust the light more easily during the vegetative and blooming stages of the plant’s life. It is preferable to utilize LED lights since they create less heat than conventional lights and will therefore keep their box cool. The amount of light produced by an LED bulb is determined by the light needs of the plants you choose.

Step 7:

A tiny hole on the ceiling of your grow box will be required for the installation of an LED light. Cut a small amount of additional wire so that you may adjust the light more easily during the vegetative and blooming stages of the plant’s development.

Using LED lights is preferable since they create less heat than conventional lights and will thus remain box cool longer if used properly. Depending on the light needs of your chosen plants, the capacity of your LED lights will vary.

Step 8:

Installing a carbon filter in your grow box may assist you in absorbing odors in the environment, and replacing the carbon filter every two cropping cycles is recommended. A few pieces of activated charcoal in a dish at the bottom of the grow box will absorb any odors created by the plants or any other materials used in the construction of the grow box if you don’t have any other options. You have completed the process and may now grow any type of plant in your grow box, including cannabis, veggies, and herbs.

How to Make Your Grow Tent Smell Proof? Best Ways to Hide the Smell of Weed!

A lot of excitement comes with growing your own marijuana! The entire process of cultivating your plant, from the seedling stage all the way up to the flowering stage, when you get to smoke the fruit of your labor, is a memorable one! However, while there are a plethora of factors that you must consider when working towards the growth of your plant, there are certain little issues that frequently arise but are overlooked. Some producers, on the other hand, find that they become a nuisance over time.

  1. In the event that you are a marijuana producer who is producing a significant amount of pot, one concern that you may have on your mind is how to make your grow tent smell proof.
  2. There are a lot of options to make your grow tent smell-proof that are both cost-effective and functionally equivalent to a home treatment for this problem.
  3. The purpose of this post is to provide you with an accurate image of what you can do to make your grow tent smell proof as we progress through it.
  4. Meanwhile, there may be other producers who are growing their marijuana in areas where it has previously been legal but is still considered a social stigma, and they do not want their neighbors to know that they are growing marijuana in their home.
  5. The question is, though, where does this odor come from?

Understanding Terpenes: Why does Marijuana Have Such a Strong Smell?

The fragrance that marijuana releases may be detected immediately! You’re familiar with the fragrance. Every smoker is familiar with the odor. Even many non-smokers are familiar with the fragrance, and even those who do not immediately recognize it will realize that it is the scent of something exceptional. A strong scent of marijuana permeates your house, and it tends to remain there for a long period of time. It may be found in your hands and mouth as well as on your clothing, furniture, carpet, and other surfaces.

  • Terpenes, which are chemical substances responsible for the scent of every plant, are responsible for the smell that we associate with marijuana.
  • However, marijuana plants emit a powerful odor even while they are developing, and while smoking increases the intensity of the odor and allows it to spread further and wider, your cannabis emits a very strong odor when it is growing.
  • Terpenes are naturally occurring compounds found in plants that help them grow and reproduce.
  • To put it another way, the more potent a strain of marijuana is, the more potent its scent will be; in other words, the more potent the smell of your marijuana, the higher the ‘high’ it will provide you.
  • A significant amount of marijuana purchasers really pick their strain of pot depending on the type of fragrance that it emits after it is harvested.
  • terpenes are also known to have therapeutic characteristics of their own, and they contribute to the overall medicinal capabilities that the marijuana plant exhibits.
  • Some terpenes have anti-inflammatory qualities, while others have antibacterial capabilities.

Some terpenes can be used to treat depression and stress, while others can be used to cure malaria, among other things. Terpenes have a variety of other advantages, and as a result, they are essential to the growth of the marijuana plant.

How to Make Your Grow Tent Smell Proof? Best Methods to Hide the Smell of Weed

It is possible to make grow tents odor-proof using a variety of techniques. The following are some of the most effective methods for concealing the smell of marijuana and making your grow-tent smell proof against the pungent odor that the marijuana plant releases.

1. Using Carbon Filters

Carbon filters, which are generally believed to be the finest remedy against the smell that marijuana releases while it is growing, are one of the most effective alternatives that you have when it comes to eradicating the smell of marijuana. In nature, activated carbon is extremely absorbent, and it is because of this feature that carbon filters are employed to keep the smell of marijuana under control. The filters will easily last you two seasons of growth and will assist you in ensuring that all of your odor is contained on the filters themselves.

2. Using Strong Exhaust Systems

Another excellent suggestion is to install a powerful exhaust system. Either you may set up a true full-sized system of growth that makes use of industrial-grade fans, or you can just place a basic pedestal fan in front of a window and turn it on when the weather is warm. If the fan is powerful enough, it will take in all of the air and expel it, ensuring that the smell of marijuana does not stay in your room for long periods of time afterwards. It should be noted that this method would remove the scent from one room or location and release it into the open air, which means that any neighbors or passersby will be able to smell the cannabis that you are cultivating and would be able to know right away!

3. Using Air Fresheners

Another effective method of suppressing the smell of marijuana is to use air fresheners. The problem with them, however, is that they are not genuinely containing the stench, but are instead substituting a harsher smell for it. When the impact of your air freshener wears off, the scent of marijuana plants will reappear in your environment. Due to the fact that the scent of the room freshener tends to fade after a time, you would either need to spray a lot of air fresheners or hunt for alternative methods.

As a result, many buyers opt to purchase carbon filters in order to make their grow tents smell-proof.

4. Using Odor Control Gels

Making use of odor control gels is still another excellent option that you have available to you. Even though they are regarded to be more potent than your standard air freshener, they perform in a similar manner. In the same way that a carbon filter absorbs the scent that marijuana plants create, odor control gels provide an overwhelming smell that prevents the smell of marijuana from being the most prevalent smell in the room.

In the case of producers who want to cultivate their marijuana in modest amounts, odor control gels and air fresheners are acceptable options; but, if you plan to grow a large quantity of marijuana, these options may prove to be prohibitively expensive.

5. Using Other Stronger Smells

This is a typical method of getting out of a jam. One of the most effective methods of concealing the scent of marijuana is to substitute it with other, stronger aromas that are less noticeable. If you use this method, it always works for a short amount of time before the cannabis scent takes over once the old scents have faded away completely. Using other strong fragrances to mask the smell of cannabis can be an effective short-term remedy if you are expecting company and need a solution for a couple of hours or longer.

This is one of the most effective methods of temporarily making your grow tent smell-proof for a limited period of time.

6. Using Air Purifiers

Using air purifiers is another excellent method of getting rid of the odor associated with marijuana. However, if you look at the construction of an air purifier from the inside, you will notice that most air purifiers are equipped with activated carbon filters, which are the fundamental reason why the smell of cannabis is confined. Sucking up odors is made possible by the activated carbon found in air purifiers, which guarantees that your grow tents are odor-free. While this might be a bit pricey, it is one of the most effective ways to ensure that all of the odor is removed from the house.

Why is the Smell of Marijuana a Problem?

Some marijuana farmers are concerned about the fragrance of their product since it is an instant ‘tell’. There’s an issue with this since some producers enjoy the “high” that they receive from marijuana, but the scent of marijuana is an instant turn-off for them. Others who enjoy using marijuana for medicinal reasons may find the scent of marijuana a little overpowering at times, and as a result, they do not smoke it but rather ingest it through other ways. The largest concern, though, is that it is a visible indicator of marijuana use, and many individuals who smoke or cultivate pot do not want others to know that they are doing so.

This mentality will take a long time to shift, and until then, marijuana, even though it is legal, will continue to be seen as a social taboo.

What is the Best Method to Make Your Grow Tent Smell Proof?

Personally, I believe that employing a carbon filter is the most effective and least expensive approach to ensure that your grow tent remains odor-free. Purchase a high-quality carbon filter that incorporates absorbent charcoal into its design.

When you consider that the purpose of a grow tent is to absorb the fragrance rather than to replace it with another scent, it performs well. The majority of other remedies are only temporary cures for the underlying problem, however employing a carbon filter is really successful.

Are There any Smell-Proof Grow Tents?

Unfortunately, there are no grow tents on the market that are completely smell-resistant. Because the scent is expelled from these tents through the use of inlet and exhaust fans, and because the fans would not function well without clean and fresh air, it is not feasible to create a grow tent that is completely smell-proof. Carbon filters, on the other hand, may be used to achieve the required degrees of smell-proofing in a system.


If you’ve been wondering how to make your grow tent smell proof, we hope this post has answered your concern. There are a variety of methods by which you might accomplish this, with carbon filters being one of the most effective. As part of our educational efforts, we offered detailed information about tarpenes, which are the underlying reason of this odor, as well as an explanation of the function that they play in the plant’s existence and its medical advantages. With this knowledge, we hope you can eliminate the odor of marijuana from your growing environment.
