What Is Cannabis Ruderalis?

The limited height and side branching of an AutoMazar or Black Jack make them the favoured hybrids for SOG, little spaces or under-canopy type guerrilla grows.


During a field trip in southern Siberia in 1942 the Russian botanist Janischewski discovered cannabis ruderalis, the third family of cannabis. Studying the known cannabis families of the Volga River region at the time he soon realized he had discovered something new. The weedy, thick stalked, but sparse, stout and quick growing c.ruderalis is a very hardy species also grown elsewhere in southern Russia. The rugged little plant is also grown in the northern Himalayas, the central and southern European states and notably in the United States mid-west. The plants short stature precludes it from being used as fibre hemp, but it has been used as an anti-depressant in Mongolian and Russian folk medicine for centuries.


Cannabis indica and cannabis sativa are photosensitive plants that have two distinct seasonal grow phases. These phases are controlled by photosensitive hormones that tell the plant when to vegetate or when to flower. When cannabis receives more than twelve hours of daylight in a twenty four hour period it will vegetate. When it receives less than twelve hours of daylight it will flower. These photoperiods are seasonally dependant when growing outdoors. When growing indoors these factors are controlled directly by the grower with lighting schedules. Cannabis ruderalis is not photosensitive and not seasonally dependant at all and will vegetate and enter the flowering cycle according to its own internal clock. Usually the truncated vegetative stage is 21 to 30 days with finishing times between 70 to 110 days from seed. This is called auto-flowering.


Sea of GreenFrom the Latin "rudera", a ruderal species is one that is first to colonize cleared areas after competing plants are removed. With a full maturation time of no longer than ten weeks cannabis ruderalis can become a dominant mono-culture on a cleared patch of land very quickly. Combined with the renowned cannabis tap root and root mat the quick maturation and re-seeding times of ruderalis makes it an ideal plant for such things as stage one permaculture preparation and desert reclamation.

Probably the most important development in cannabis breeding over the last fifteen years has been the mastering of high quality recreational and therapeutic automatic strains. Ruderalis played an important role in this breeding breakthrough. Master growers have been able to capture the medical depth and psychedelic range of standard photoperiod plants, but with the distinctive short seed to flower grow time of the ruderalis. These "auto-flower" strains do not need their light environment manipulated to start the flowering phase of growth, but will automatically flower. Ruderalis by nature is low in THC, but high in CBD (cannabidiol) which is making it the go to parent species for medical cannabis breeders.
