Siberian Ruderalis

Siberian Cultivar Description


Hardy Ruderalis From The Southern Ural Region

This Siberian Ruderalis is a giant and vigorous autoflowering variety with good trichome production. The villagers near Lake Chebarkul have been using these semi-wild plants for making some incredibly flavorful, high CBD Charas.

This Siberian Ruderalis variety can thrive in some of the most inhospitable places on earth. It shows great vigor, hardiness and extreme flowering speed. Furthermore, the autoflowering gene allows these landrace plants to grow in places where most cannabis strains wouldn’t stand a chance.

This Cherbakul landrace strain is likely to be the result of a past hybridization between the landraces originating from nearby Kazakhstan and the local Ruderal variety. This would explain the pungent citrusy smell, high trichome production as well as the mild psychoactivity of most phenotypes.

Central Asia is likely to be the place were cannabis was domesticated for the very first time, over 14 000 years ago.

These seeds are the result of 4 generations of controlled open pollination. The goal has been to decrease the proportion of weak plants and hermaphrodites while preserving a high genetic diversity. This meticulous process led to its successful adaptation for indoor cultivation.

XXL Autoflowering Strain

The plants automatically start flowering after only 2 to 3 weeks after germination. During the flowering phase, the Siberian Ruderalis plants steadily grow taller, reaching heights of 120 to 190 centimeters. To maintain a manageable height indoors, most growers top them multiple times. As the flowering cycle nears its end, a stunning transformation occurs, with over 25% of the plants adorning a mauve/purple hue.

Our friend “Guardian of the Lost Terps”, a member of the “Russian Landrace Bureau” handpicked the seeds (The first generation) directly at source.


Originating from a land of extreme cold, with average January temperatures of -21°C, these seeds possess a sturdy, waterproof shell. This unique adaptation ensures they sprout only when winter’s grip has loosened, flourishing in late spring.

To kickstart the germination process effectively, we recommend cold treating or cracking/nicking the seeds. A fantastic tip is to soak the seeds in water containing Aloe Vera gel, and then gently crack them after the soak. This method has been proven to yield outstanding germination rates of over 80%.

Note that each seed pack contains extra seeds so growers can practice the seed cracking method.

A Very Light Feeder

Not only are these plants vigorous but they need very little nutrients in order for them to flourish. Thriving in rocky soil in their natural habitat, they require even fewer nutrients than most landrace strains.

Caution is essential, as these plants are highly sensitive to nutrient burn. To ensure their optimal growth, it’s best to provide a relatively poor soil environment. However, during the second half of their life cycle, a gentle nutrient solution can be introduced to support their journey to full maturity.

The Siberian Ruderalis Landrace could therefore be a precious asset to breeders looking to create hardy XXL autoflowering strains with a unique flavor.

    Excellent strain, I plant it everywhere I can just to keep this land race alive. Although not super potent THC-wise it Is great to make concentrates. I personally also made a 50/50 hybrid with a 100 percent indica afghan autoflower that packs a stronger albeit still mild punch. This is the only site I use now!

    Duperie génétique, stable et résistante, une odeur de citron/menthe ..floraison très rapide.
