Beginners Guide to Achieve Grow Room Odor Control

If you have an indoor grow room with grow lights, you might have noticed the odors that plants produce. Depending on the plants you have, you feel different types of odors.

Controlling odor inside a grow room is one of the challenges that the grower has to face. It is necessary to get rid of the odor by having a complete odor control system inside the room.

If you are a beginner and want to know everything about grow room odor control, you are in the right place. We will see why plants produce odor, how you can control it, and everything that a grower should know.

Let’s start!

What Does Plant Odor Mean?

Plants emit volatile organic compounds (VOCs) in various stages of their life, especially in the flowering stage.

These volatile organic compounds are the chemicals that evaporate and stay in the air and produce a particular smell. These are responsible for the odors in your grow area.

Depending on the plant you are growing, there are different types of odors. Some plants produce a non-irritating smell, while some produce a noticeable and pungent smell. Some odors are pleasing, while some orders are annoying.

If you own a grow room, you might have witnessed different types of odors. It is necessary to have a grow room odor control to eliminate or mitigate the odor in the grow area.

Why Do You Need to Control Odors in Your Grow Room?

There are many reasons to control odors in the grow room; some of them are given below.

To Maintain Privacy

The first reason for having a grow room odor control is to maintain privacy. If you want to keep your grow room secret, odor control is necessary.

You will never want others to find out you have a grow room inside your house; therefore, you need to control the order so that no one notices what you are doing.

The people passing by or coming into your house will figure out you have an indoor grow room through the odor.

For People Working in Your Grow Room

The odor coming from the plant is not pleasant all the time, so the workers working inside the grow room find it irritating. They cannot work properly in a place that produces odors because it also affects the air quality.

Thus, you need to get rid of the odor and maintain an odor-free environment so that your workers can work without any problem.

Neighbors Don’t Like the Odor

Most of the time, your neighbors will never bear the plant odor. It can often lead to complaints or even lawsuits in the worst cases.

The odor of the plants is not what everyone likes, and surely, people around your house would never like to smell that odor.

If you have a grow room odor control system, your neighbors will never find out that you have an indoor grow room. They will not smell any kind of odor.

Air Quality of the Grow Room

The odor also affects the air quality of the indoor grow room. Your plants also need fresh air to grow well and provide the optimal yield.

Poor ventilation is not good for plants and the yield. Thus, you need to control the odor and make your indoor grow room odor-free.

How to Control Grow Room Odors?

The grow room owners can opt for different types of indoor grow room odor control systems. They can pick a suitable one to solve the issue.

Carbon Filter

Carbon filters are the most common for commercial grow room odor control, and these can also be used inside your small indoor grow area.

The filter contains activated carbon that absorbs the grow room scents/odors and makes the air odor-free. Therefore, these are usually part of the ventilation system.

These filters are placed along with your exhaust fan, and the air is pushed inside the carbon filter.

Activated carbon is capable of absorbing the odor chemically; the smell gets trapped inside the pores. Thus, there is no odor in the air coming out of the filter. It is one of the simplest grow room odor control systems for indoor growers.

The grower needs to decide how many carbon filters he needs according to the size of the grow room. But keep in mind that there should be one carbon filter on every exhaust you have to prevent the odor from going out of the indoor grow room.

You also need to maintain the carbon filters so that they can work properly. Otherwise, they will not be able to filter the odor. You need to replace the carbon filters every three to six months.

Ozone Generators

Ozone generators are also used for commercial grow rooms. The generator produces ozone which has three molecules of oxygen.

Unlike oxygen gas, ozone is highly unstable. The molecules of the ozone break their bonds immediately.

If we look at the molecular structure of ozone, there are three molecules attached. The third molecule breaks the bond, and the result is an oxygen gas molecule that is stable and an unstable oxygen atom that combines with the odor inside your grow room.

Once the molecule combines with the odor, the volatile organic compounds producing the odors are oxidized, and the odor is eliminated. Therefore, ozone generators are good for grow room odor control.

Control the Air Extraction and Exhaust

As a rule of thumb, you should draw less air from the environment than you extract. Experts say that the intake of air should be 20% less than the exhaust.

By doing so, negative pressure will be created inside your grow area. Due to this negative pressure, the odor will be expelled out of your grow room. But make sure to install a carbon filter to absorb the odor before releasing the air outdoors.

Odor Neutralizers

Odor neutralizers are excellent for eliminating the smell in your indoor grow area. These are quick and give promising results for grow room odor control.

You can easily find odor neutralizers in the form of blocks, sprays, and gels. They can either absorb the volatile organic compounds producing the odor or create a bond with them.

If the odor modules remain on the odor neutralizers’ surface, the odor is masked, and you cannot feel it.

Sometimes, the VOC molecules also create a bond with the molecules of odor neutralizers, and in this case, the odor is permanently eliminated.

You can place a few blocks inside the ducting. The air going through the duct will be neutralized by the odor neutralizer.

The order neutralizer sprays are the quickest to deal with the odor. You can use them inside your grow room to instantly get rid of the odor. They are also helpful in removing the odors from your clothes as VOCs can also stick to them.

Air Purifiers

Air purifiers can also be used inside grow rooms, and they are commonly preferred for commercial grow room odor control.

They can not only eliminate the grow room smells, but they can also remove the dust, microorganisms, and other particles in your air. The resultant air is purified, which is free from any kind of odor and impurities.

However, air purifiers are pretty expensive, and they do more than odor removal, so they are not used in the first place. In addition, some air purifiers do not work on the strong odors produced by indoor plants.

Keep the Humidity in the Optimal Range

Humidity control is necessary for your indoor grow rooms because high humidity is not good for the plant. If the humidity of your indoor area is not in control, it will be a favorable environment for mold, mildew, and other microorganisms.

Therefore, it should be in control to keep the plants healthy.

When the humidity and heat are not in control, the plants tend to produce more odor. Moreover, you need to control humidity to lower the odor inside the grow area to have an effective grow room odor control.

You can use a thermo-hygrometer to keep an eye on the humidity and temperature. To reduce humidity, you can use dehumidifiers and air circulation fans.

Role of LED Grow Lights in Grow Room Odor Control

Grow lights are also responsible for the odors inside your grow area. If the grow lights are producing too much heat, they are creating a favorable environment in which there will be more odor in the area.

In addition, high temperature also increases the humidity in the grow room, which is also harmful to your plants and favorable for odors.

Thus, the choice of grow lights matters a lot. There are different types of grow lights available. Some produce excessive heat, while some produce minimal heat.

LED grow lights are the most efficient. About 70-85% of the electrical energy is converted into light; therefore, a minimal amount of energy is converted to heat. These lights are suitable for commercial as well as small indoor grow areas.

LED grow lights are a bit more expensive than other grow lights, but they reduce your energy bills because of their high efficiency, and they have a much longer lifespan. Thus, they are cost-friendly in the long term.
