Aroma is the distinct smell created by a plant’s terpenes. Strains of cannabis vastly differ from each other in smell, all depending on their specific terpene profile. Terpenes are located in the resin glands of the plant. Female cannabis plants give off the most potent aroma to attract insects for pollination. To draw in more pollinating insects, the plant will release more terpeneresin.
The aroma of a strain of weed depends on a few factors, ranging from age of the plant, type of soil, water, fertilizer, light, and time of day. (Sometimes it can smell different in the morning than it does late at night.) There are reportedly over 200 different terpenes among cannabis plants. Strains are usually named for their unique smell or blend of smells. Scientists have determined that the scent that cannabis gives off is primarily to protect the plant from predation.
The aroma that terpenes produce has had many different therapeutic uses, such as raising energy levels, relieving insomnia, and even to helping create a sense of calm. Some of the more common cannabisterpenes are myrcene, limonene, caryophyllene, terpinolene, and pinene. Each is said to have its own set of unique therapeutic benefits for the user.
Many users will keep their cannabis in a sealed glass jar to preserve the terpenes’ aroma. Each terpene is useful for identifying one strain from the next. When you grind up cannabis in a grinder, it unlocks the potent smell even more.
