Hemp, like any other plant, has a distinctive odor. Every grower can recognize it. But only true connoisseurs of this noble plant know that each quality marijuana variety has its own exclusive aroma which can be easily identified by its hue.
The cannabis aroma comes from the formation of aromatic substances called terpenes. They are natural organic compounds of the carbon class produced by plant biosynthesis. It is the terpenes that are the main components of resins, oils and balsams. In nature, these substances are needed by the plant to attract insects that pollinate them, or to scare away herbivorous animals. The most common scents are citrus (lime, lemon, grapefruit), pine, and freshly scraped earth. But there are often unusual specimens such as hemp scented with coffee, ripe berries, and spices.
Why does hemp smell?
The intensity of the smell of hemp depends directly on the amount of resin produced. The more resin produced, the more terpenes it contains. Because resin is synthesized by cannabis plants to protect them from environmental stresses, any stress, especially during the flowering stage, will result in an active resin production. The emitting fragrance will intensify. When, because of external factors, the plant begins to think that it is about to die, the survival instinct is activated. Hemp actively begins to produce terpenes to attract the insects that must pollinate it to continue its lineage.
To increase the intensity of the cannabis aroma, it is enough to let the soil dry out by delaying watering the plant for a few days. The lack of moisture will make the plant actively produce resin, the aroma will become much richer. Accordingly, to make hemp smell less, you should water it regularly.
This is pretty much what happens when you put a plant in a dark place for a few days. It begins to think that winter is coming and that it does not have long to live. Active production of terpenes begins in order to speed up the production of offspring.
The dry, hot climate also increases the intensity of the cannabis aroma. The terpenes begin to evaporate under the influence of high temperatures and are released into the air. Humid environments and temperatures below +28 degrees can reduce odor concentrations in the surrounding area.
