Cannabis ruderalis is a small, low-THC Cannabis type from Central and Eastern Europe and Russia that flowers based on age rather than day length, so it finishes quickly. The key to growing it is that it can be grown in long summer days without a light cycle change.
Cannabis ruderalis is a variety, subspecies, or species of Cannabis native to Central and Eastern Europe and Russia. It contains a relatively low quantity of the psychoactive compound tetrahydrocannabinol (THC) and does not require a photoperiod to blossom (unlike C. indica and C. sativa). Some scholars accept C. ruderalis as its own species due to its unique traits and phenotypes which distinguish it from C. indica and C. sativa; others debate whether ruderalis is a subspecies under C. sativa.
Seeds of C. ruderalis were brought to Amsterdam in the early 1980s in order to enhance the breeding program of seed banks.
C. ruderalis has lower THC content than either C. sativa or C. indica, so it is rarely grown for recreational use. Also, the shorter stature of C. ruderalis limits its application for hemp production. C. ruderalis strains are high in the cannabinoid cannabidiol (CBD), so they are grown by some medical marijuana users.
C. ruderalis was first scientifically described in 1924 (from plants collected in southern Siberia), although it grows wild in other areas of Russia. The Russian botanist, Janischewski, was studying wild Cannabis in the Volga River system and realized he had come upon a third species. C. ruderalis is a hardier variety grown in the northern Himalayas and southern states of the former Soviet Union, characterized by a more sparse, "weedy" growth.
C. ruderalis is traditionally used in Russian and Mongolian folk medicine, especially for uses in treating depression. Because C. ruderalis is among the lowest THC producing biotypes of Cannabis, C. ruderalis is rarely used for recreational purposes.
