Ruderalis
Cannabis Ruderalis is a low THC sub species of cannabis, native to areas in Russia, central and Eastern Europe, and Asia. Some scholars debate whether Ruderalis should be considered a subspecies distinguished from Indica and Sativa. Cannabis Ruderalis is shorter than Indica and Sativa counterparts, reaching only 1 to 2 ½ feet tall at harvest time, with thicker stems and smaller buds. Ruderalis is considered to be autoflowering, as the flowering cycle is induced by maturity typically in 21 to 30 days, rather than the photoperiod Indica and Sativa varieties.
