Weed Smell & Odor Control Guide

Smell Control in Your Farm/Grow Room

Maintaining odor control in your cannabis farm or grow room is crucial to ensure that the pungent smell of the blooming flower does not disturb your surroundings. While you may be accustomed to the odor from your garden, it is essential to consider the impact on your neighbors. Over time, the overpowering smell can fill your entire home, regardless of the size of your garden.

Thankfully, some techniques can significantly control the smell of fresh cannabis flowers. Regardless of size, these techniques can be applied to any indoor grow facility.

By using these techniques in collaboration, you can thoroughly flush out the smells, creating a near-odorless environment – not just for your comfort but also for your neighbors.

This article will examine some of the industry’s standard best practices to help you eradicate the overpowering smell of cannabis growth..

Management of Temperature and Humidity Levels

The temperature and humidity levels in your grow space are two significant factors when it comes to odor management. Keeping your humidity and temperature levels up helps handle odor concerns.

During their vegetative stage, cannabis plants emit a relatively mild odor; at this early phase, the plants are yet to produce terpenes – the component that gives the buds its smell.

As cannabis plants transition from the bloom phase to flowering, the trichomes follow suite. These trichomes produce a high volume of smell-producing compounds.

As they go through the developmental stages, they increase humidity and temperature levels to handle the odiferous condition. Controlling such odor may include using air conditioners and dehumidifiers in your grow space.

Maintaining Good Air Circulation

Adequate air circulation in your farm is one particular way to improve temperature and humidity. Remember, the lights in your garden produce high heat. The heat produced varies across the light capacities. For example, a small grow system with LEDs and compact fluorescents may be easier to manage than ceramic metal halides or HIDs.

Nevertheless, these small or large lights can dry up your farm with inadequate air circulation or ventilation.

Typically, farmers allow air to move across their garden for several minutes while at the vegetative phase. The frequency of the permitted air increases at the bloom phase. Good air circulation is continuously reducing odors and temperatures, and it allows easy passage of used CO2 out of your garden.

One widely used approach is providing your growing space with fans. Oscillating fans, standing fans, ducted inlets, and outlet fans will be useful. These air circulation promoters are most efficient when used together.

A CFM-rated fan is an ideal choice. This specific fan indicates the capacity (in cubic feet) – the air a fan can cover in a minute. Knowing your farm’s meter/cubic foot measurement helps determine the appropriate fan specification for your space.

Anti-Odor Gels

You’d expect a more pungent odor in the last six weeks that ushers during full maturity.

The trichomes produce the highest terpenes concentration at this stage, which accounts for the strong discomforting smell. Even with a good ventilation and circulation system, you’d still perceive traces of the flower’s scent at some point. 

At such times, you may seek other supportive anti-odor techniques to complement the first established anti-odor systems.

An odor-absorbing gel is an excellent addition. These are gels designed to replace odors with more appealing fragrances. Take note – these gels do not get rid of the smells, they conceal them.

You may also consider anti-odor sprays; as with the odor gels, the sprays do not drive out smells, they only conceal them as well.

Now, you and your neighbor will only share a pleasing smell throughout your neighborhood.

Carbon Filters

Also called “carbon scrubbers,” this tool helps you get rid of up to 90% of your garden’s odor. The device is tailored to capture air particles with activated and ionized carbon. It traps hair, mold spores, dust, and volatile organic odor-carrying compounds.

The carbon filters serve either of two purposes in your garden. When placed on the floor, the filter recycles clean air into your grow space; and for rooms with filters and exhaust, besides redistributing heat, they also stale depleted air.

Carbon filters come in various sizes and shapes. A duct fan helps complement the filters’ effect. The ducted fan serves to disseminate bad air through the filter or to expel clean air from the filter. 

Carbon filters come in different models and designs, opt for a reputable brand and trusted model when choosing carbon filters. You also would want to select a filter that suits your garden space. 

As with fans, you may prefer carbon filters with CFM ratings.

Most times, carbon filters work best when placed at the highest point in your grow space, where most heat tends to accumulate. 

How to Get Rid of Weed Smell Tips

To assure you of an odor-free grow space, you will need proper ventilation, controlled temperature with fans, and carbon filter.

There are still odor traces that will linger, but the use of odor gel or spray will handle that. Also, carbon scrubbing eradicates bacteria spread by air form; it can significantly lower the number of bacteria in the air.

You should be able to avail of all the tools and items you need on your trusted hydroponic supplier and hardware store.

When growing cannabis indoors, know that the associated odors are not suitable for everyone. Either one or a combination of these inexpensive approaches will save you a lot in the end.

Even if you’re used to the smell, you wouldn’t want your family, friends, or neighbors to get bothered by the smell.

The concept of indoor growing cannabis is probably to keep your activities discreet. Be humble and stay low, and let your products speak for yourself.
