Check odor

The smell of cannabis can be pleasant to some, but can be a nuisance to others. If you grow cannabis indoors, the smell can also be a problem for those around you. However, there are ways to control the smell of cannabis while growing. Below are some of the best methods for minimizing the smell of cannabis.

  1. Use odor filters

One of the most effective ways to control the smell of cannabis is by using odor filters. These filters remove the smell of cannabis from the air before it spreads through the house. Odor filters are usually placed in the extractor hood of your grow room. Make sure you choose a filter that is suitable for the size of your grow room and the amount of cannabis you are growing.

  1. Ventilate your grow room

Another way to minimize the smell of cannabis is to properly ventilate your grow room. This means that you need to have good extraction to replace the air in your grow room. Make sure you clean the extractor regularly and replace it when necessary.

  1. Use odor-absorbing materials

There are some materials that can absorb the smell of cannabis. An example of this is activated carbon. This material is often used in odor filters and can also be used to minimize the smell of cannabis. Place some activated charcoal bags in your grow room to absorb the smell.

  1. Check the humidity

High humidity can enhance and spread the smell of cannabis. Keep the humidity in your grow room below 60% to limit the smell. If the humidity is too high, it can also lead to mold growth, so it's important to keep an eye on this.

  1. Choose low-odor cannabis strains

Some cannabis strains have less odor than others. If you want to minimize the smell of cannabis, it's a good idea to choose low-odor strains. For example, choose strains that have been specially developed for indoor growing and that have less odor than strains that are grown outdoors.

6. Keep your grow room clean

A clean grow room is essential for controlling odors when growing cannabis. Regularly remove plant debris, dirt and dust from your grow room to prevent odors from building up and spreading.

In addition, use an air filter system to purify the air in your grow room. There are several types of air filtration systems available, such as carbon filters and ozone generators, that are effective in removing odors from the air.

  1. Use odor absorbing materials

There are several materials you can use to absorb odors in your grow room. Odor absorbing materials such as activated carbon, zeolite and charcoal are effective at capturing odor molecules in the air. Place these materials near the air inlet and outlet of your grow room to trap the odors before they can spread.

  1. Grow low odor cannabis strains

Some cannabis strains naturally have less strong odors than others. If you are concerned about the smell of your grow, choose low odor strains such as Northern Lights, Blue Mystic or Lowryder.

  1. Use air fresheners

If all of the above methods aren't enough to control the odors in your grow room, consider using air fresheners. There are several types of air fresheners available, such as aerosol and electric air fresheners, that can reduce odors in your grow room. Just make sure you choose an air freshener that is safe for use in a grow room and does not release any harmful substances that could affect the quality of your cannabis.

  1. Choose the right time and place to grow

Finally, it is important to choose the right time and place to grow cannabis. If you live in an area where cannabis is illegal, consider growing your plants indoors to prevent odors from spreading outside. In addition, it can help to only grow your cannabis plants when the conditions are right, such as a period with little wind and high humidity. This can help reduce the spread of odors.

By applying these methods, you can effectively control the smells of cannabis while growing. This way you can enjoy your home-grown cannabis undisturbed without having to worry about the smell.
