What is a Cannabis Ruderalis


Table of Contents

Let’s get to know the famous cannabis ruderalis, a cannabis wild-growing species popular with users interested in receiving higher CBD content. Cannabis Ruderalis is a common, hardy weed plant that has become wild in Russia and Central Asia. It is a keystone resource for marijuana breeders, known to cross breed ruderalis with many other species to produce hybrids with certain features of it, like autoflowering.

Cannabis ruderalis are considerably smaller, usually developing only 1 to 2.5ft tall, than sativas and indica. Ruderalis crops become stalkier even amongst the three main marijuana species, with a smaller number of extra branches and smaller palmate-shaped buds. Ruderalis plants have no special lighting requirements, unlike most other species, that means they are also suitable for those active in growing crops outdoors.

The Origin of Ruderalis

The name itself is derived from the ancient greek word ruderal, that in the world of plants corresponds to a species that has been invaded by humans as the one to colonize land. It is suspected that Cannabis ruderalis arose millions of years ago in regions in Central and Eastern Europe, mainly in Russia, in which it continues to flourish as a herb. Wild ruderalis can be observed also today rising near highly populated areas including roadways.

In 1924, Cannabis ruderalis had first been described by the Russian botanist D.E. Janischewsky studied marijuana and found a plant in significant variations of form, size and seeds compared to other marijuana plants that were previously labeled.

Properties and Characteristics

The Cannabis ruderalis is often a small, stalky crop, particularly if contrast to its counterparts, indica and sativa. Usually, at harvest, it stands around 1 and 2.5 ft tall, with a rough and bushy growth rate which produces broad leaflets who articulate themselves in a light green color. The buds appear to be thin, but still somewhat chunky, from ruderalis plants, and are supported by the robust, thick stems. Modern marijuana ruderalis hybrids typically start flowering around 21 to 30 days just after seeds were already cultivated, irrespective of the light period. That’s why most of it hybrids are referred to as strains of “autoflowering.”

The flowering period that is triggered as per its development rather than enabled by the photoperiod like indica and sativa varieties is what really distinguishes ruderalis. In ruderalis strains, the high concentration of CBD has also greatly aided breeders that cross indicas and sativas with cannabis ruderalis strains to create autoflowering hybrids which produce elevated amounts of CBD.

Ruderalis is Autoflowering

Marijuana ruderalis are ‘autoflowering,’ unlike many other marijuana plants, that indicates this can shift from the vegetative stage to the flowering period independently of whether there is a difference throughout the light period. As marijuana plants generate flowers which contain a high amount of cannabinoids and other healthy nutrients, the reproduction phase is important. Regardless of the light-to-dark amount, 3 to 4 weeks since growing from seeds, typical ruderalis plants can start flowering under their own. However, the indica and sativa plant are considered to have a “photoperiod” feature, which means that it will only start its flowering stage if they are on the switching cycle of 12 hrs darkness everyday.

Marijuana growers should be the one to put the plants on the photoperiod by switching the light cycle to 12/12. It is widely believed that after arising far north of the equator, ruderalis adjusted the power to autoflower, where light periods are short and changing periodically.

This implies that although photoperiod plants such as indicas and sativas can flower only under tight indoor environments when periods of darkness and light are regulated, or when light is reduced during the winter season, autoflowering ruderalis can grow everywhere and develop flowers through the year.

Cannabis ruderalis alone’s effects are reduced by its naturally low in THC content. However, for breeders who want to take advantage of its autoflowering trait, the stability and short lifespan make it flexible and desirable. Its features give breeders the opportunity to produce an autoflowering hybrid with its genetic partner’s advanced potency and taste characteristics. Ruderalis are high in CBD that makes it non-psychoactive CBD that has increased in popularity over the years, and is naturally higher in cannabidiol.

THC, the psychoactive chemical that induces a euphoric high, also produces very little. Since Marijuana ruderalis are high in CBD and have low content THC, for those people who are interested in the healthy goodness of the marijuana plants, it is a more common option, but are looking to escape much of the euphoric effects commonly linked with the use of marijuana.


Because of its low THC levels, it was thought to be of little interest to recreational users. Although breeders tried their best to bring the best of all worlds together, producing both recreational and medical autoflowers that really can grow very quickly from crop to harvest. While its bud might not be among the available at any marijuana dispensaries, numerous users do not understand the impact on overall range and experience of a little marijuana species. Growers were able to change the genes from their other strains by using the power of cannabis ruderalis, giving them autoflowering features, raising their CBD amounts, and producing a harder, more durable marijuana crop.
