Why it is important to control, grow room odor

Below are some of the reasons why many cannabis growers would want to control their weed grow room’s odor.

Discretion and security

Not every cannabis grower wants everyone to know what they are doing or planting. A smell emitting from the grow room may compromise your discretion and security irrespective of whether you live in a state that legalizes the growing of cannabis or not. It even becomes more problematic if you live in a country that does not allow the growth of the crop.

Dealing with nosy neighbors may also not be an easy thing to do. It may cost you some friendships, especially in cases where some people regard the growth of weed as something that is not right.

Respect

Keeping the odor at bay is also a sign of respect to your neighbors and visitors to your home. Do not assume that your neighbor will appreciate the smell of your favorite strain as much as you do. Allowing the smell to seep out of the grow room, again may gain you the wrath of your neighbors that may take forever to undo.

Low airflow in the grow room

A smell emitting from the grow room may also be an indication that the air circulation in the grow room is lacking. It could also mean that the ventilation setup you have put in place is not ideal, or there is too much heat in the grow room. If by any chance, you can smell the odor from the crops and grow room, you should go through the whole area to carry out a thorough investigation and rectify the problem.

Tips on Cannabis Odor Control

In as much as cannabis odor is part of what makes the crop stand out from the rest, too much odor in the grow room is not as pleasing. Controlling the grow room environment is one of the best ways of ensuring that your crops do not emit any odor, which may compromise your safety and security. Crops also grow better in an environment that is perfect in every way, including fresh and odorless clean air. There are many ways to control odor in your grow room and below, are some of the most effective ways.

Fit air and surface purifiers

People growing weed for commercial purposes have the biggest hassle in managing marijuana odor control in their grow rooms. One of the reasons for this is the number of crops in the grow room is larger than that of a non-commercial grow room. The best solution for commercial growing spaces is the installation of air and surface purifiers because they come in sizes large enough for bigger grow rooms.

The purifiers remove all airborne particles in the grow room, leaving it fresh, with a clean airflow, and more tolerable for both the crops and the grower. Some of the impurities that the purifiers get rid of are mold, pollen, smoke, bacteria, viruses, and dust, among others.

Improve air circulation

Cannabis plants need adequate air circulation through all their stages of growth. Besides lowering the odor levels, proper air circulation also helps to keep the temperatures in the grow rooms low. Adequate air circulation also helps to recycle any used carbon dioxide out of the grow space leaving only clean air.

Growing cannabis indoors requires the use of grow lights that have varying heat levels. During the different stages of growth, crops need proper ventilation to cope with the heat from the grow lights. Some of the lights come with in-built fans, while others do not have them.

In case you are using grow lights without any inbuilt fans, ensure that you install enough fans depending on the size of the grow space. Fans come in different types and sizes, all with varying air circulation levels. Pair the fans with exhaust fans and air ducts to get clean air that keeps odor away from the room and the crops.

Install dehumidifiers and air-conditioners

Another way of controlling odor in the grow room is by managing the room temperature and humidity effectively. The humidity levels of the cannabis crop drop as they grow through different stages. Weed requires less humidity in the flowering phase than it does in the vegetative phase.

If you notice that there are higher temperatures and humidity levels than there should be, you should install air-conditioners and dehumidifiers to help tackle the issue. The gadgets will not only eliminate the odor, but hey will also ensure that the crops grow under the temperatures and humidity levels they require for them to thrive.

Setup a carbon filter

Another way of managing odor in a grow room is by installing a carbon filter. A carbon filter is an exhaust with activated charcoal and pores. It helps to trap particles in the air that include mold spores, dust, and hair, among others. Activated carbon filters can manage 90% of weed odor control in a grow room effectively. Carbon filters last long, and they are easy to install and maintain. They are also highly practical and readily available.

Use odor neutralizing and absorbing gels.

Cannabis growers will go to any lengths to mask the odor in their grow rooms. Sometimes masking the scent may require emergency solutions such as using absorbing and neutralizing gels. Gels are best for small grow rooms. The gels absorb the aromas from the plants, but they can only do so for a short period.

They also come with their scents that can alter the smell of the buds if left to stay in the room for longer than they should. The length at which you should use an absorbing or neutralizing gel or spray will depend on the size of the product, the size of the grow room, the number of crops, and the levels of humidity and temperature in the growing space.

Use ozone generators

Using ozone generators is not a very common practice, but it is just as effective as all the other methods in the industry. The people that use ozone generators are mostly commercial cannabis growers. Just like the carbon filters, ozone generators get rid of all contaminants in the grow room that include mold spores, pests, bacteria, and odor.

The generators work by producing ozone, which reacts with the pollutants to break them down to less harmful molecules through oxidation. In short, the generators use oxygen atoms to get rid of bad smell in a grow room.

Grow strains with fewer odors

All the above tips will help in the reduction of weed odor in the grow room, but you can go a step further to ensure that you get a minimum scent. You can choose to develop strains that emit low natural odor as they grow. Some of the most popular low odor strains include Northern Lights, Blue Mystic, and Durban Poison, among others.

Durban poison is a pure Sativa strain that produces giggle fits and a cerebral buzz after smoking. It has a distinctive taste of cinnamon and licorice, but it does not have any potent odor during its flowering stage.

Northern Lights may have one of the most skunk tastes and smells when smoking, but it does not emit any odor during the flowering stage. Blue Mystic has a berry fruity and smooth flavor when smoking it. Blue Mystic is an Indica strain that flowers in only ten weeks, and it grows with a mild odor during the flowering phase.

Another strain that you can grow without worrying about an odor during the flowering phase is Caramelicious. The strain is one of the easiest to grow, as it requires minimal management. It produces high yields, and it does better indoors than it does outdoors. The smoke from the strain feels and tastes like dessert, and it is famous for its relaxation effects.

FAQs

Is it possible to tell when cannabis plants start to smell?

Yes, it is possible to tell when marijuana starts to smell. In the early stages during germination and the early vegetative stages of growth, cannabis does not have any odor. In the late vegetative mode, the smell remains minimal but faintly distinctive in some strains. At this stage, it is also easy to monitor and manage odors easily.

The way to monitor the odor is by rubbing your finger against the stem and sniffing the finger. At this stage, the most likely smell will be sweet, skunk, or musky. The leaves may not have any odor at this stage. During the flowering stage, all these changes as the plants start to reveal their sexes.

Terpene production during the flowering stage goes up, and if you have feminized strains, you can expect strong odors to follow with the fast growth. Terpene aromas increase with the coating of the trichomes. During this stage, if you do not do anything to mask the odors, you may not prevent anyone from outside the grow room from finding out that you are cultivating cannabis.

How safe is it to use ozone generators to grow room odor control?

You may have read about some organizations asking weed growers to stay away from using ozone generators. The best alternative to use instead would be carbon filters. In as much as ozone generators manage odor control, they are not the best devices to use as they may cause health issues to the people that encounter their applications.

In some states, using ozone generators is illegal, which goes to show just how risky they are. They are also a new concept in the market and expensive for small scale weed growers. The following links could provide more information on the dangers of ozone generators to cannabis growers.
