Chemovar refers to a specific chemical variety of cannabis plants, based on their chemical composition, which includes the presence of different cannabinoids, terpenes, and other compounds. It is sometimes used interchangeably with the term "strain."
Cultivar refers to a cultivated variety of cannabis plants that is selectively bred to have specific characteristics, such as high THC content or a certain flavor profile. Cultivars can be indica-dominant, sativa-dominant, or hybrid, depending on the genetics of the parent plants.
Strain is a term that is often used interchangeably with cultivar or chemovar to describe a specific variety of cannabis plants that has been selectively bred to have certain characteristics.
Dominance refers to the genetic makeup of a particular cultivar or strain. A cultivar or strain can be indica-dominant, sativa-dominant, or hybrid, depending on the proportion of genetics inherited from each parent plant. Indica-dominant strains tend to have more relaxing, sedative effects, while sativa-dominant strains tend to be more uplifting and energizing. Hybrid strains are a combination of both and can have a range of effects depending on the specific genetics.
