Autoflowering cannabis strains are direct descendants of the infamous Cannabis Ruderalis species. It is thought to originate in Central and Eastern Europe, as well as Russia, where it was first officially discovered by botanist Janichewski in 1924. From a pure botanical perspective, we do know that Ruderalis based strains proliferate in hostile environments with harsh climate conditions. In addition, autoflowering strains do not follow a lighting regime, but rather grow “by age”. Initially discarded for the low potency and small yields, autoflowering strains have been heavily used since the 90s in several breeding projects, and serve today as the basis of semi-auto cannabis strains (see Outdoor Strains). They have become increasingly popular in the last ten years, due to their improved yield, aroma and potency.

What are Autoflowering Cannabis Strains
Ruderalis based strains proliferate in hostile environments with harsh climate conditions. Autoflowering strains do not follow a lighting regime, but rather grow “by age”. Also they have been heavily used since the 90s in several breeding projects, and serve today as the basis of semi-auto cannabis strains (see Outdoor Strains).
Appearance of Autoflowering Cannabis Strains
The appearance of autoflowering cannabis strains resemble the one of Cannabis Indica varieties. Those varieties tend to grow shorter and bushier with heights not exceeding 120cm. They present a sturdy shape, producing smaller leaves of a rather dark green. Autoflowering strains will start flowering automatically, event that occurs after 4 to 6 week of life.
Growing Autoflowering Cannabis Strains
All in all, autoflowering cannabis strains do not require excessive care and attention. Being able to grow in harsher climate conditions, they can handle stress and deficiencies better than their Sativa and Indica counterpart. Autoflowering strains do not require a high feeding regime, and more importantly they don’t follow any light schedule.
