Marijuana Strains & Cannabis Genetics

Welcome to the original Marijuana Strain Library. Here you will find detailed information on cannabis strains, including strain origins and genetics, strain-specific grow tips, smoke reports, descriptions of the effects, and more.

Marijuana strains are either pure breeds or hybrid varieties, typically of the species Cannabis Indica or Cannabis Sativa. Large variety of weed strains are continually developed to highlight a specific combination of properties of the plant or to establish marketing differentiation. Strain names are typically chosen by their growers, and often reflect properties of the plant, such as taste, color, smell, or the origins of the strain.

Cannabis Indica Strains

Cannabis Indica plants get their genetics from the original landrace strains of India, Bangladesh, Afghanistan, and Pakistan, where they were used primarily for the production of hashish. Unlike sativa, smoking indica buds typically results in a heavier, sedating stone, which is why they are often used for pain relief by medical marijuana users. When growing, indica weed plants tend to be somewhat compact, and have tight nugs and wide leaves.

Cannabis Sativa Strains

Cannabis Sativa plants are quite different from their indica counterparts in both the way they grow and the way they smoke. Known for its cerebral, uplifting high, sativa strains are very popular among recreational smokers as well as with the medical marijuana community. It is widely used to relieve anxiety, depression, and muscle tension, among other things. Sativa weed plants usually grow quite tall, and take longer to flower, but make the extra effort with higher yields.

Hybrid Marijuana Strains

Hybrid marijuana strains are much more common these days than pure indica or sativa. As more cannabis breeders cross different strains in an effort to combine and better favorable genetics, many wonderful hybrids have been introduced to the world. These weed strains combine their parents’ genetics and often have a wonderful balance of both indica and sativa characteristics.
