Cannabis Ruderalis

Although it’s not nearly as popular as indica and sativa, ruderalis has become a more prevalent species in more recent years. Originating from Central Russia, it has a similar chemical profile to hemp and contains very low levels of THC.

Classification

The name ruderalis comes from the word ruderal, a term used by botanists to describe hardy, non-domesticated plants. So any breed of cannabis that has the ability to adapt to extreme environments and avoid human cultivation has been classified as ruderalis. Only recently have indoor growers begun to utilize the characteristics of the ruderalis plant to influence new hybrid varieties.

Plant Characteristics

This stalky species of cannabis only grows to a height of 1 to 21⁄2 feet tall (30.5cm to .75m) and produces small, chunky buds. But what really differentiates the ruderalis from indica and sativa is its flowering cycle. Unlike the other cannabis species, ruderalis’s flowering cycle is induced according to its maturity and not by the photoperiod (seasonal changes in night length), a process known as auto-flowering. This auto-flowering can begin in as little as 21 days.

Hybrids

Over time, growers have combined their top indica, sativa, or ruderalis strains to create strains with the best aspects of both parents, known as hybrids. One well-known hybrid is Afghanica. This strain, once erroneously identified as indica, is an indica-predominant strain with a potent and sedating high. Great for indoor or outdoor growing, the plant can grow between 5 and 6 feet (1 and 2m) tall, depending on the setting.

Another well-known type of hybrid is an auto-flowering strain. As you might expect, this comes from cross-breeding a strain with ruderalis. Very popular with growers, this hybrid is easy to grow due to the short time from seed to harvest and its ability to flower when mature rather than when seasonal changes happen.
