Ruderalis, often called the “third strain” originated in Central Asia. Ruderalis is technically and usually Cannabis sativa, and like its cousins, Indica and Sativa, is an annual plant in the Cannabaceae family. The name “ruderalis” comes from “ruderal”, a term given to wild cannabis plants.
Unlike many other plants, it is autoflowering which means the plant flowers automatically once it reaches maturity and is not reliant on the strict light/dark hours required by other plants.
Because of the lower concentration of THC, it doesn’t provide many of the medical effects unless crossed with an Indica or Sativa. Growers make the decision between an Indica vs. Sativa and create a hybrid to reap the benefits of the growth properties of the Ruderalis Strain. If you compare the plant type, it is somewhat short and stalky.
