Ruderalis

Cannabis ruderalis was first described by Russian botanist Dmitrij Janischewsky in 1924, who identified it as a distinct species growing wild along roadsides and abandoned fields in southern Siberia. The plant evolved in extreme northern latitudes where summer days exceed 18 hours and a reliable photoperiod-triggered flower would never receive enough darkness. Instead, ruderalis developed an internal genetic clock: it begins flowering automatically 3-5 weeks after germination regardless of light cycle. Pure ruderalis plants are agriculturally useless — they yield 10-30 grams of low-potency flower per plant. Their value lies entirely in the autoflowering gene, which is recessive but transferable through breeding. The first commercial autoflower strain was Lowryan #2 (Joint Doctor Seeds, 2003), a cross of Mexican Rudy x Northern Lights #2 x William's Wonder that established the autoflower category. Today every autoflower seed on the market — Royal Critical Auto, Auto Blueberry, Northern Lights Auto — traces its day-neutral flowering back to ruderalis genetics. Modern "auto" hybrids contain roughly 25% ruderalis DNA, enough to preserve the autoflowering trait while delivering 15-22% THC and 80-150g/plant yields. Ruderalis is also the only Cannabis subspecies native outside of Asia in significant wild populations.
