Over the years, the use of recreational and medical marijuana has been legalized in some states. Together with this, policies on home cultivation of the plant have also been granted with specific conditions. Cannabis users are now able to save more money and guarantee quality buds because of a more controlled set-up when they are growing their own. However, there may be a tiny drawback to this gain. As we all know, marijuana plants give off a distinct pungent aroma. The particular scent is usually recognizable to the majority, users, or nonusers alike. Although this may be tolerable to some, it can also be bothersome for others and mean trouble. That is why as home growers, you should be able to find ways to mitigate this problem.

Where does Marijuana odor come from?

As mentioned, cannabis plants can release a pungent aroma. Just like any aromatic plant, cannabis releases a strong aroma to attract pollinators and prevent predators. Their scent may not be that noticeable during the earlier stages of their growth, but the intensity increases as they reach the flowering stage. Furthermore, the scents of growing one to two plants may not be a worry. However, growing a substantial amount of cannabis, even indoors, can be so hard to mask that you can draw unwanted attention even from afar. 


The scents of cannabis plants are brought about by the mixture of its different chemical components. However, it is noted to be chiefly influenced by the secondary compounds it contains, which are terpenes or “terps”. These compounds can be found on the Trichomes which are appendages or small outgrowths on the surface of cannabis. This highly contributes to a scent that can range from fuel-like to earthy and woody to citrus and floral. Despite that, this does not explain the skunk-like aroma that is often frowned upon by others. In a research study, it was believed that volatile sulfur compounds (VSCs) give cannabis its skunk scent. They utilized 13 cannabis cultivars that were analyzed for their smell by a four-person panel. The results revealed that the plant containing the highest concentration of VSCs ranked as the most pungent one. It was also discovered that going towards the end of the flowering stage the prenylated VSCs increased significantly. This stage is also when you would note the pungent aroma is most intense.

The third molecule detaches itself from the composition and attaches to and reacts with pollutants, bacteria, viruses, and molds, which contributes to the strong pungent smell cannabis gives off.

Utilizing a generator in your grow room can help create a good environment for your plants.
