How To Control Smell In Grow Tent

How To Smell Proof A Grow Room

The basic answer to this question is no, grow tents do not have the ability to block off odors. It is possible that the grow tent will have to cover the aroma of your flowering plants before the space can be considered smell-proof. While grow tents are distinctive for a variety of reasons, you must exercise caution if you want to keep the fragrance under wraps. There are several advantages to employing a grow room, including temperature regulation, enhanced lighting, and humidity control, to name a few.

Proper air circulation will assist you in keeping the temperature and odor levels in your grow environment stable and consistent.

Making certain that the grow room has adequate airflow will assist you in achieving the finest ventilation outcomes.

Even the smallest lighting systems, such as light-emitting diodes and miniature fluorescents, are not without their own set of difficulties.

What Strengthens the Odor in A Grow Room?

If left undisturbed, the scent of a blossoming plant may linger in the air for long periods of time, becoming increasingly potent. Factors like as high humidity and temperature are likely to contribute to the persistence of ascent in the growing region for an extended period of time. As a result, the first thing to take into consideration is to assess the moisture and temperature levels in the space. In addition, it’s crucial to remember that various plant species have a wide range of germination requirements.

  • You may resolve the problem by utilizing resources such as dehumidifiers and air conditioning units.
  • Locate the exhaust fan on the top area of the carbon filter, at the position where the aroma is the strongest, and turn it on.
  • It’s simply a matter of allowing the cleaned air to return to the room.
  • While this may appear to be an additional cost to your project, the total benefits make it a sensible choice in the long run.

How Do I Control the Smell In My Grow Room?

Yes, it takes a lot of effort to keep the fragrance of your grow room under wraps, especially when a flowering plant is approaching harvest time. Being able to construct an enclosed air environment where the fragrance would not escape is typically seen as a difficult challenge. The primary reason for such an occurrence is that plant pots require air in order to perform photosynthesis effectively. While a result, as new air is introduced, the old air must be exhausted in order to maintain humidity levels and give temperature control benefits.

There are several strategies you may employ to lessen the degree of stench originating from your grow room, as previously mentioned. Generally speaking, these strategies assist you in partially eliminating or redirecting the stench in a new way.

1. Use Smoke Absorbing Gel

The use of an absorbing gel in a grow room is one of the most effective means of eliminating odors from the environment. When it comes to regulating smells in grow rooms, Ona Gel is one of the most trusted names in the business. It is a product that is both cost-effective and durable. In addition, the Ona Gel brand manufactures a variety of different odor-absorbing gels that you may use in your grow room to reduce odor. Essentially, these gels function by neutralizing odors in the air, which in turn helps to reduce the perfume of blossoming plants.

While these gels are effective to a certain amount, if you have a few plants that have a strong odor, these gels may not be appropriate.

Furthermore, the aroma of blossoming plants is generally fairly distinct, so you may need to combine this strategy with other approaches to get the best results.

It is possible that you may need to use the gel in conjunction with some air fresheners in order to keep any odours confined.

2. Get A Good Carbon Filter

Using a carbon filter to manage the aroma of flowering plants in a grow room is a practical solution for managing the scent of flowering plants. In most cases, using a carbon filter in conjunction with an inline fan yields the greatest results. The majority of carbon filters are made up of used blocks, which act to capture carbon and neutralize any odors that may be present. As well as being prevalent for growing environments like as grow rooms, carbon filters are also used for a variety of other purposes.

Having said that, even the most effective carbon filter will not be able to completely eliminate the scent from your grow area.

The amount of air that can be cleaned in a given length of time is determined by the power of the fan and the size of the carbon filter.

In order to identify the most appropriate carbon filter size, you will need to take into account a number of other parameters as well.

3. Temperature and Humidity Control

This holds true for every phase of the planting procedure, including the soil preparation. When the temperature and humidity levels in a certain region are high enough, the aroma of blossoming plants is substantially enhanced. You’ve probably questioned why garbage collections outside smell the worse during the summer months rather than the winter.

It’s because the temperature is higher in the summer. It’s the same situation as a grow room, really. It is possible that the aroma of marijuana will be enhanced by high humidity and temperature levels, particularly during summer months.

4. Direct Ventilation Exhaust The Right WaySeal Up Holes

All aspects of the planting process are affected by this rule. If the temperature and humidity levels in a specific region are high enough, blossoming plants will emit a strong aroma. You’ve probably questioned why garbage collections outside smell the worse during the summer months rather than the winter. It’s because the temperature is higher during the summer. As far as a grow room is concerned, the situation is the same. It is possible that the aroma of marijuana will be enhanced by high humidity and temperature levels, particularly during summer.

Should I Use an Ozone Generator?

In general, an ozone generator is not recommended for use in a grow room that has inadequate ventilation. More specifically, an ozone generator is not recommended for use in a grow room, especially during the harvesting and pruning seasons. Ozone has the potential to negatively impact your general health, and you should investigate other solutions to the problem. These include ventilation fans, which you may place in strategic locations around the room to provide more ventilation. In addition, the usage of ozone generators is a complex procedure, as evidenced by the fact that certain jurisdictions, such as California, have put tight rules on their use.

It is possible to get ozone generators from a variety of different manufacturers, each with a slightly varied air capacity.

How to FindInstall the Right Carbon Filter

When installing a carbon filter that is appropriate for your needs, there are just a few basic procedures to follow. The processes may differ depending on a variety of factors, including the manufacturer of your filter and others. They are as follows:

Calculate the Exhaust Diameter

The majority of typical air-cooled grow lights include large 6-inch exhaust openings, which are ideal for providing ventilation when necessary. The majority of small-scale farmers who live in tents will benefit from a unique mix of resources, such as a fan, ducting, and an activated carbon filter. What makes a 6-inch exhaust hole appropriate? The 6-inch fans, on the other hand, are strong enough to deflect air away from the grow chamber. The air flow from the grow room area is frequently too feeble for any small-sized fan to be effective.

Determine the CFM Rating of your Fan and Filter

In addition, you must guarantee that the CFM rating on the carbon filter is the same as or higher than the CFM rating on the fan itself. This will allow you to get the highest possible level of efficiency when it comes to air ventilation. When you take this strategy, you can be certain that the filter is only cleaning a little volume of air at a time. Consider the following example: if you have a filter with a rating of “300 CFM,” the fan should likewise be rated at “300 CFM.”

Install A Fan and Filter Into the Exhaust System

The following step is to connect the exhaust fan and filter to the exhaust system. The use of a fan is essential for the proper ventilation of the grow room. While there are no precise procedures to follow throughout the installation process, you must make certain that the fans and filters are installed in the proper locations. By taking this strategy, you will guarantee that you install a resource that is quite effective at cleaning the air in the grow room. Growing plants in a grow room might be one of the most successful approaches available for the task.

Even if you are unable to completely eradicate the smoke, there are a variety of efficient remedies available to address the issue.

Aside from that, environmental elements such as temperature and humidity Medicinal marijuana plant owners who wish to regulate the fragrance of their grow rooms in locations such as dispensaries are an excellent example.

Techniques such as gels, charcoal filters, inline fans, and other similar devices are all beneficial. Furthermore, employing a mix of these strategies would be the most effective method of managing the odor.

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.

  1. It all boils down to finding the most effective method of controlling it.
  2. We’ve also included several low-cost alternatives to the traditional techniques of odor-proofing grow tents.
  3. You may use any one of them or a combination of them to create a worry-free marijuana growing environment.
  4. 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

Even while it’s hard to completely eliminate the aroma, an air filter with activated charcoal can reduce the stench of cannabis in your grow environment by 90 percent. 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. A pre-filter is used to keep odor-causing volatile organic substances such as mold spores, dust, and hair from entering the system. Ionized carbon molecules within the filter’s primary cylinder can sometimes capture and hold onto those contaminants when they are exposed to light.

  • 4-inch carbon filter equals 260 CFM
  • 6-inch carbon filter equals 530 CFM
  • 8-inch carbon filter equals 780 CFM
  • 10-inch carbon filter equals 860 CFM
  • 12-inch carbon filter equals 1765 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.

Controlling Smells & Odors in The Grow Room

What exactly is that smell? Have you ever been standing in a quiet place with no one else around and caught a whiff of marijuana on the breeze? No matter if you couldn’t see where the source was coming from, you wouldn’t dispute what your nose was telling you. A distinctive and strong aroma associated with cannabis is one of the plant’s most enticing characteristics. That same lovely fragrance, though, is easily identifiable and can create a great deal of difficulty. If you have growing marijuana plants in your grow room, you are creating a factory for that delectable tell-tale fragrance, and in order to safeguard your females, you must make that smell unnoticeable.

When it comes to eliminating odors from the grow room, there aren’t many solutions available to growers.

When it comes to a tiny grow with only one or two plants, you can typically get away with masking the scent.

In order to ensure that you are not leaking any scents that can attract the notice of inquisitive neighbors, you will likely need to cleanse the air after a major growing operation. The following are the most effective methods of eliminating odors from your grow room:

  • The following items should not be used: Carbon Filter/Scrubber
  • Odor neutralizers
  • Air purifiers
  • And Ozone Generators.

These are, without a doubt, the most effective method of minimizing marijuana grow room aromas. Carbon filters (also known as ‘carbon scrubbers’) are capable of physically pulling scents from the air and neutralizing any aromas that do travel through them. Carbon filters are required if it is necessary to neutralize the air that is expelled from your vehicle’s exhaust. It is impossible to mistakenly release the scent of cannabis into your neighborhood with a decent carbon filter installed in your air conditioning unit.

When using a carbon scrubber, you must create an environment in which the odorous marijuana air is driven through the filter.

Setting up a carbon filter as part of your exhaust system in a sealed grow tent and using an exhaust fan to move hot air away from your grow area is the most typical way to accomplish this.

An example of a carbon filter in a grow tent– this equipment removes all scents from the air, ensuring that odors do not escape the tent’s perimeter.

  • They are incredibly efficient
  • Once they have been put up, they are quite simple to maintain
  • And they endure a long time.

How to FindInstall The Right Carbon Filter

1.) Determine the diameter of your exhaust pipe (or pipes). Many typical air-cooled marijuana grow lights (also known as 6′′ air-cooled hoods) are equipped with a 6′′ exhaust hole (thus the name). For the majority of small-scale growers that use a tent, you will want to get everything in 6′′, which includes the fan, carbon filter, and ducting (if applicable). What is the significance of 6 inches? A 6′′ fan is powerful enough to expel the air from almost any small-scale grow operation. In contrast to 4′′ fans, which are frequently insufficient for 4′′ carbon filters, typical air-cooled grow lights will not fit.

  1. 2.) Compare the CFM ratings of the fan and the carbon filter.
  2. This not only assures optimal efficiency, but it also provides an additional layer of security by ensuring that your carbon filter only takes in as much air as it needs to effectively scour for smells.
  3. A 600 CFM fan would draw in more air than a 300 CFM filter could deodorize in a single minute.
  4. The 6′′ Carbon Filter (300-400 CFM) is matched with the 6′′ (400 CFM) Fan–6′′ Ducting.
  5. 3.) Connect the exhaust fan and filter to the system.
  6. Because the carbon scrubber is located at the back of the exhaust system, the possibility of blossoming cannabis odor escaping is reduced significantly.
  7. It has been my experience that placing an exhaust fan on top of a carbon filter and positioning it where the stench is the highest would help in an emergency situation to purge a room of odors.

It looks somewhat like this: You don’t even need to connect the fan to anything; you can simply allow the cleaned air to circulate back into the space.

This is something I learnt from a dispensary owner.

It is suggested that you do not use these items in your grow room or tent if you have blooming cannabis plants growing in them.

Although not as effective as a grow area, these are quite good in neutralizing scents outside of it.

These products are intended to bond with unpleasant odors in order to “neutralize” the odors they encounter.

Many other types of products, including incense, “bathroom sprays,” and cologne, have been reported as being used by marijuana farmers to mask the odor of a blossoming marijuana plant.

It is also possible that applying these solutions on your cannabis plants can lessen or modify the natural fragrance of your plants.

As soon as the stench enters your grow room, it just gets stronger and more pervasive until the crop is harvested.

Sprays, Glade Plugins, and other similar products– The majority of the time, they are only effective for a few hours at the most.

In an emergency, the following is the best spray to use: Ozium Air Sanitizer– This smells quite “citrus clean,” and it appears to do a good job of masking the scent of cannabis without making you smell like you just sprayed a load of Febreeze all over your house.

All you need is a simple spritz of perfume!

Ona Products is a highly recommended marijuana odor neutralizer.

The fact that they are so successful in neutralizing scents has resulted in their availability to the general public.

When used in a small grow room, they are efficient in masking odors, albeit they only last for a limited period of time and must be replaced every few weeks to a few months.

You will be able to cover practically all odors with a few blooming plants in a grow tent or closet, and one or two of them placed outside the grow area will completely mask the stench.

You will not be able to smell your cannabis plants if you use Ona products in your living room, den, or other open sections of your home.

Because Ona products might diminish or modify the fragrance of your cannabis buds if they are in the same room as your flowering plants, you should avoid placing Ona products in the same room as your flowering plants if at all possible.

You might also direct your exhaust air to pass over an Ona product just before it is vented to the outdoors.

Ona products are intended for usage outside of the growing environment.

What is the duration of their existence?

The majority of growers report that they last at least 4-6 weeks, which is plenty time for a couple of them to offer covering throughout the stinky second half of the blooming cycle.

Many air purifiers make the promise that they may reduce odors, which is normally achieved through the use of a filter.

No, not at all.

But these are not powerful enough to remove all of the odours from a growing environment.

As a result, while air purifiers may be a smart choice for other reasons, I do not advocate purchasing one only for the purpose of attempting to eliminate odors from your grow room.

Ozone generators claim to be able to eliminate smells, purify the air, and destroy mold and mildew among other things.

What exactly is the big deal?

So much so that they are now considered illegal in the state of California, where I currently reside (see:).

And maybe most significantly, ozone generators are harmful to your health! Here are only a handful of them, along with links to studies from credible organizations, all of which conclude the same thing: Ozone producers are harmful to human health.

  • ‘In fact, when ozone is breathed, it has been shown to cause lung damage.’
  • OSHA (Occupational Safety and Health Administration) of the United States
  • Ozone is classified as a “Major Indoor Air Contaminant” by the Environmental Protection Agency.
  • “Ozone is a powerful lung irritant, and exposure to excessive levels is a contributing factor to the worsening of lung disease,” according to the EPA.
  • “In populated locations, it is not recommended to utilize ozone-generating equipment.” “Ozone is a respiratory irritant.”

Growing techniques such as blowing ozone out of the home or ensuring that ozone only enters the exhaust are claimed by certain growers to be safer than others. Again, we highly advise against the use of ozone since, in the best case scenario, it is only capable of performing the same functions as a carbon scrubber. Possibly the most serious consequence is that it is damaging the lungs of you, your pets, and your family. Make Certain That Only YOU Get to Enjoy the Smell of Your Plant!

5 Ways to Control Odors in a Growroom

Cannabis plants emit volatile organic compounds (VOCs) into the atmosphere in order to produce their distinctive scent. It’s only that these volatile organic compounds (VOCs) may produce pretty strong, unpleasant odours that might serve as tell-tale signals of what you’re producing, which you may not necessarily want everyone to know about. The good news is that, with a little know-how, these odors may be readily eliminated, decreased, or prevented altogether, resulting in a healthier environment.

Carbon Filters / Carbon Scrubbers

A carbon filter is by far the most effective method of eliminating growroom odor. Before the air is taken from the growroom, they practically scour the air to remove any lingering plant odours. Carbon filters are a critical component of your ventilation system’s performance. The extractor fan draws in air from your growroom and passes it through a filter that has an activated carbon layer. It is during this process that the smell emanating from your plants is caught and held inside the pores of the activated carbon.

  • The deeper the carbon bed, the greater the amount of activated carbon present.
  • Carbon filters will successfully keep the odour of the plant from escaping from the grow chamber.
  • A reducer can be used in the event that this is not the case; however, the effectiveness of your fan and filter will be reduced as result.
  • Maintaining your carbon filter properly will ensure that it continues to function as efficiently as possible for as long as feasible.
  • Using pre-filters and filter covers can help prevent dust and debris from entering your carbon filter, which can shorten its lifespan.
  • This will be determined by the type of filter you choose.
  • It is not recommended to use a humidifier in your growroom that uses unfiltered water.

This may be avoided by always using RO (reverse osmosis) water in conjunction with your humidifiers. Using reverse osmosis, you may demineralize or deionize water by forcing it through a semi-permeable membrane while applying pressure to the water in the process.

Negative Pressure

In a growroom, negative pressure is the ideal type of pressure to have. This signifies that there is more air exiting the growroom than there is being brought in to the growroom. The advantages of negative pressure include the ease with which temperature and humidity may be controlled, as well as the reduction of growroom odor. It is recommended that you use a less powerful intake fan so that you are drawing in 20 percent less air than you are extracting. Otherwise, your tent will become too full of smelly, unfiltered air which will begin to seep out of zippers and seams before it has a chance to pass through your carbon filter and create negative pressure.

Ozone Generators

Rather than masking scents, ozone generators actually eliminate them from the environment. They accomplish this through the process of oxidation. Ozone is made up of three oxygen atoms (O 3) that are chemically linked together. It’s similar to the oxygen we take in, but with an additional oxygen atom. Oxygen atoms are typically found in pairs because of their strong bonding properties. This makes O 3 very unstable, with the additional oxygen atom breaking off and attaching itself to organic molecules such as volatile organic compounds (VOCs), which are responsible for plant odors.

  • There are various different types of ozone generators available on the market.
  • They serve as an additional layer of protection, ensuring that all smells are eliminated before the air is withdrawn.
  • For further information, see The Most Up-to-Date Automation Options for Cannabis Cultivation.
  • Generally speaking, if you do use an ozone generator, it should not be utilized outside of the growroom, especially in a residential setting, due to the potential health hazards associated with it.
  • Children, the elderly, and persons suffering from asthma are among those who are most at danger.
  • It can also aggravate chronic respiratory disorders such as asthma by irritating the eyes, nose, throat, and lung tissues.

If you intend on working in your growroom for a lengthy amount of time, it’s also a good idea to turn off any ozone generators you may have. The greatest aroma is produced by cannabis plants during their blossoming period.

Odor Neutralizers: Blocks and Sprays

These are the most effective and safest neutralizers to utilize outside of your growing area in order to maintain peace of mind about any odours that you suspect may have made their way out of your growroom. The use of odor neutralizers outside of the growroom is strictly prohibited due to the fact that they are so effective that they might have a negative impact on the final smell and taste of your harvested product. You may, on the other hand, purchase blocks that are designed to sit in your additional line ducting.

When it comes to eradicating scents from your clothes after you have left the growroom, the sprays are excellent.

Additionally, they can be irreversibly linked to the neutralizer’s contents by a chemical process, and so permanently cancelled out and destroyed.

Controlling Heat and Humidity in Flowering

During the blooming stage of the cannabis plant, the aroma is at its strongest. For starters, this is the time of year when the buds are maturing and all of the oils and terpenes are at their peak concentrations. Second, the rise in temperature and likely humidity during flowering will serve to accentuate this even further. In order to avoid rot, fungus, and mold, you should maintain your humidity level low during blooming anyway. However, this is an additional incentive to keep it low because scents become more intense in humid circumstances.

  • (See also: Managing Cannabis Fan Leaves for more information.) If you are having difficulty controlling the temperature, which is causing the humidity to rise, you might want to consider upgrading to LED lights or cooling your lights by blowing air from outside the tent over them.
  • SummarizeIt is true that one of the most enticing aspects of cannabis, both to the producer and to the end user, is the strong, distinct scent that the plant emits.
  • As a result, it is critical to eliminate the odor from the workplace completely.
  • By either removing the odor from the air or devising a means to mask its presence.
  • When expanding, it is always advisable to be considerate of others who may be in the vicinity of your facility, no matter how little or huge that institution may be.

What’s that smell? Odor control in the Grow Room

Written byMark W. Butwellon the 24th of November, 2015. If you are a cannabis grower then you are familiar with the strong odors that this herb produces within a grow tent or room. This is especially true during her flowering stage. The unfortunate thing is that this delightful smell can be recognized easily and may cause you a lot of trouble. In this article, we’ll take a look at some of the different options available for neutralizing the smell of your plants. There are basically two ways to go about it: either you find ways to remove the smell from the air, or you cover it up with something to mask the smell.

However, if your grow space is bigger and includes more plants, then you are better off finding techniques to eliminate the scent.

Use Carbon Filters Carbon filters are also known as carbon scrubbers and are the traditional means of managing smells in a grow room.

If you are in need of neutralizing the air that comes out of the exhaust, then carbon filters are your best option.

These devices are meant to employ activated carbon which collects pollutants and odors through a chemical process from the air and then pushes them through a filter.

This means that you need to install a push or pull fan that will pull or push air through the carbon scrubbers.

Installing them this way ensures that there is an exhaust fan that draws hot air out from the grow area.

Carbon scrubbers are very effective, easy to maintain after set up and are durable.

Use Odor Neutralizers Unlike the carbon filters that work by ‘scrubbing’ odors from the air, odor neutralizers work by covering up the smell.

They usually have fragrances that are so strong they can overshadow the grow room smells.

This is because strong neutralizers work very well to the extent that they can alter the flavor of the plants’ buds over time.

There are instances where growers have attempted to use incense, sprays, or even colognes to cover the smell of flowering crops.

If you choose to use odor neutralizer to manage the aromas from your grow room, ensure that you choose a neutralizer that is consistent.

In fact, the smell just gets stronger as time progresses.

These neutralizers are easy and quick to use.

When using Ona products, you need to be ready to replace the gel or the blocks each week or over several months.


Conversely, they are not strong enough to rid cannabis smells from the grow room or tent.

Consequently, this only makes them marginally effective.

They may not be an appropriate choice for growers who are looking to clear the smell of cannabis out of larger grow rooms.

Use an Ozone Generator “How an Ozone Generator Works 1000 564 a.png” v_shapes=”Picture x0020 13″ These devices are relatively new and are used to neutralize odors in your grow room.

The use of odor generators in grow rooms have several pros and cons.

The approach to using carbon filters and ozone generators to remove odor is basically the best option and it’s affordable.

This will also create an uncomfortable environment for mites and spiders which helps to keep them in check.

The disadvantage of ozone generators is the fact that these devices are so effective to the point that they can alter the flavor or even the aroma of the crops in your grow rooms, and exposure to these generators for long periods of time may be harmful to your health.
