Cannabis Odor and how to deal with it

Introduction

When growing cannabis, whether for medicinal or recreational purposes, it’s crucial to address several key issues. One of the main challenges for cannabis growers is the potent smell of cannabis. Which can be difficult to control, and sometimes problematic. Proper control of the cannabis scent can make the difference, between a sustainable and a disrupted cultivation operation. In this article, we will look at some of the best strategies for controlling cannabis odor. Which also respect the environment and ensure the health and safety of both you and your neighbors.

The smell of cannabis is one of the most recognized characteristics of this plant. This strong, characteristic odor is from terpenes, a group of chemical compounds generally responsible for the smell and taste of many plants. Cannabis has a very high terpene content, which is why its smell is so strong and pervasive.

Controlling Cannabis Odor

There are several different ways to control the odor of cannabis. Below are some of the most common methods, that cannabis growers are using:

Using Carbon Filters

One of the most common methods for controlling cannabis odor is the use of an activated carbon filter. Activated carbon is capable of absorbing a wide range of smells and chemical compounds. Making it an ideal choice for cannabis growers. You put carbon filters typically into the ventilation system and absorb odors from cannabis before they can enter the air.

Carbon filters, specifically activated carbon filters, are highly effective at trapping and neutralizing the odors in the air.

Growers are using these filters typically in conjunction with an exhaust system. The smelly air is sucked into the filter, cleaned, and then exhausted out. To maximize the effectiveness, match the size of your carbon filter to your fan’s airflow rate and the size of your grow room. For example, if you’re growing in a 3x3x6 ft grow tent with a 200 CFM (cubic feet per minute) fan, you should get a carbon filter for at least 200 CFM.

Using Odor Neutralizers

There are various types of odor neutralizers that can be useful in controlling cannabis odor. These products work either by neutralizing odor molecules or by emitting a stronger scent that masks the cannabis smell. When choosing an odor neutralizer, it’s important to select a product that is safe for your plants.

Odor neutralizers, as the name suggests, neutralize odors rather than masking them. They come in various forms, like gels, sprays, blocks, or even electronic air purifiers. Odor neutralizers often contain compounds like cyclodextrin, and essential oils. That can absorb and neutralize the odor molecules in the air.

For example, a product like Ona Gel Pro is a popular choice among growers. You simply open the lid and place the container in your growing area. The gel evaporates over time, neutralizing odors in the process. It’s crucial to note that these neutralizers should be put outside the grow room as it can affect the odor profile of the cannabis if placed inside.

Good Ventilation

A good ventilation system is a fundamental tool for controlling cannabis odor. Regularly airing out the grow room helps to carry away the smell of cannabis while also ensuring that your plants receive enough fresh air. You should be choosing ventilation to correspond with the plant life cycle.

A robust ventilation system can significantly help control the odor. It involves exchanging stale air inside the grow room with fresh outdoor air. This can be done by an efficient exhaust system with inline fans and ducting.

For example, you might set up a system where air is drawn through a carbon filter, then exhausted outside via an inline fan. You will simultaneously draw, fresh air into the grow room through passive intake holes or an active intake fan. Proper ventilation not only helps control odor but also regulates temperature and humidity, contributing to overall plant health.

Using Ozone Generators

Ozone generators are another option for controlling cannabis odor. Ozone is a strong oxidizing agent that can neutralize the smell of cannabis. But be careful, ozone can be harmful to humans and plants if exposed to high concentrations.

Ozone generators work by producing ozone, a molecule consisting of three oxygen atoms. This molecule is highly reactive and can interact with odor molecules, effectively neutralizing them. However, because ozone can be harmful to both humans and plants, these generators should only be used in unoccupied spaces or for air exhausted directly outside and won’t be re-circulated in the grow area.

A product like Airthereal Commercial Ozone Generator can generate up to 5000mg of ozone per hour, which can be highly effective for odor control in larger operations. Remember to follow all safety instructions when using such devices.

In conclusion, each method has its pros and cons, and often a combination of these methods is used for optimal odor control. It’s essential to consider the size of your grow operation, your budget, and safety factors when deciding on the best approach for you.

Conclusion

When growing cannabis, it’s important to realize that controlling cannabis odor is a necessary part of the process. There are many methods to deal with this issue, from carbon filters and odor neutralizers to ozone generators and ventilation systems. By selecting the right method for your situation, you can ensure your growing is safe, efficient, and as stealthy as possible to your surroundings.
