Product Description

Details

Giant and vigorous autoflowering strain with good trichome production. The villagers near lake Chebarkul (Russia) 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. The high vigor, hardiness and extreme flowering speed combined with the autoflowering gene allow these landrace plants to grow in places where most cannabis strains wouldn't stand a chance.

This Chebarkul landrace strain is likely to be the result of a past hybridization between the landraces originating from nearby Kazakhstan and the local Ruderalis 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 3 generations of controlled open pollination. By decreasing the proportion of weak plants and hermaphrodites while preserving a high genetic diversity, we were able to adapt this strain to indoor growing.

The plants automatically start flowering after only 2 to 3 weeks after germination. As the Siberian Ruderalis plants are flowering, they keep getting taller and taller until they reach 120 to 190 centimeters. Towards the end of their flowering cycle, over 25% of the plants turn purple. Not only are these plants vigorous but they need very little nutrients in order for them to thrive. Even less so than most landrace strains because they naturally grow in rocky soil.

The Siberian Ruderalis comes from a place where the winter is extremely cold (-21°C in January on average). Therefore, the seeds have a very thick, waterproof shell which allows them to only sprout in late spring when the winter is over. For that reason, cold treating or cracking/nicking the seeds is recommended. Soaking the seeds in water containing Aloe Vera gel and cracking them after the soak allows to achieve germination rates over 80%.

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

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

The Siberian Ruderalis Landrace could be a precious asset to breeders looking to create hardy XXL autoflowering strains with a very unique flavor and high CBD content.

Genetics Ruderalis landrace strain (P4) from Cherbakul (Russia), open pollinated indoors to increase the sexual stability.
Structure Tall and vigorous ruderalis strain. The plants quickly develop a strong root system and grow very fast. The internodal distance is long. The buds are generally slightly fluffy but certain phenotypes can have relatively dense clusters.
Bouquet Citrusy, sweet, floral, piney and spicy undertones.
High Mild high, soothing, and relaxing.
Terpene profile It has not yet been tested.
Growing Tips Cracking/nicking the seeds is paramount. Soaking the seeds in water containing aloe vera gel and cracking them after the soak allows to achieve germination rates over 80%.

The optimal light cycle indoors is 18 hours of light for 6 hours of darkness. Indoors these vigorous autos can reach 120 to 190 centimeters. That is why most indoor growers top them off a couple of times in order to keep their final height manageable. These plants are extremely sensitive to nutrient burn and require a very poor soil to thrive. Mix coco coir or sand/rocks with the soil in order to make it poorer. Note that the plants can receive a mild nutrient solution in the second half of their life cycle.
