Is there a strong smell emanating from your growroom? To clear the air of unwanted odors, you have two main options. You can either find ways to remove the smell from the air, or you can cover it up. Here are some ways to rid your grow tent of odors.

Carbon Filters

Carbon filters, also known as carbon scrubbers, are standard odor-control devices in growrooms. Carbon filters use activated carbon, which adsorbs impurities and aromas from the air through a chemical process, trapping them inside the pore structure of the carbon substrate and ensuring the smells do not leak into your neighborhood.

If you decide to use carbon scrubbers, then you need to ensure odors will be forced out through the filter. This means you need to install a fan that will pull or push air through the carbon scrubbers. The most common way of doing this is to set up the filter so it forms part of the exhaust system.

As the exhaust fan draws hot air away from crops, the carbon filter scrubs the odor from the air as it passes on its way out. Carbon scrubbers are effective, easy to maintain after set-up and durable.

Odor Neutralizers

Unlike carbon filters, which extract odors from the air, odor neutralizers cover up the smell. Odor neutralizers are formulated to combine with unpleasant smells. They usually have fragrances that are so strong, they overshadow the growroom smells. Odor neutralizer products should be placed outside of grow tents or growrooms that have flowering crops because strong neutralizers work so well, they can alter the flavor of your plants’ buds over time.

There are instances where growers have attempted to use incense, sprays or even colognes to cover growroom smells. Such products aren’t strong enough to neutralize the smell for the long term and it can alter the crop’s organic smell. If you use odor neutralizers to manage the aromas from your growroom, make sure you choose a neutralizer that is consistent. Once your plants begin to produce the flowering scent, they will not stop until your harvest. In fact, the smell just gets stronger as time progresses.

Air Purifiers

Air purifiers, also called air filters, are said to reduce odors through a filtering process. While some air filters help dissipate odors from the air, air purifiers lack the strength to draw all odors out of a growroom. Consequently, this only makes them marginally effective. These devices can be a great choice for other reasons, such as size and portability. They may not be an appropriate choice for growers who are looking to clear smells out of larger growrooms.

Ozone Generators

These devices are relatively new and are used to neutralize odors in your growroom. They are capable of cleaning the air, clearing odors and killing mildews and molds. Ozone generators also kill bacteria, not only in the growroom, but also in carbon filters and exhaust fans. In my opinion, using both carbon filters and ozone generators together to remove odors is the best option and it’s affordable.

Ozone generators are highly effective at removing odors from the air. This will also create an uncomfortable environment for mites and spiders, which helps keep them in check. The main disadvantage of these devices is that they are effective to the point that they can alter the flavor or even the aroma of your crops. Also, long-term exposure to ozone generators may be harmful to your health.
