Autoflowering seeds are sativa or indica species that are crossbred with a ruderalis species. Once you cross an indica or Sativa with a ruderalis, a fast flowering cultivar is produced, which gives a tremendous amount of yield. Ruderalis is native in areas with short summers, such as Northern Europe, Russia, Mongolia, and China.
Since these areas have minimal summer days, this variety is automatically programmed to flower in a short period. This means that there’s no need to alter the light cycle to encourage the plant to transition to the flowering stage.
