Autoflowering strains are descendants of the Ruderalis species of Cannabis. Autoflowering strains are those that do not depend on the light cycle to start flowering. They are perfectly capable of growing on their own with minimal interference. They aren't fussy and require no alterations in their cycle. Of course, they do go through a vegetative period that lasts for only 4 to 6 weeks, after which they enter the flowering stage. On average the entire life cycle, i.e. from seed to harvest, takes only 9 to 12 weeks for most of the autoflowering strains on the market today. Despite their compact stature and structure, autoflowering strain can produce great yields.
