Autoflowering cannabis switch from a vegetative stage to a flowering stage based on age rather than the ratio of light-dark hours they get. Autoflowering seeds are hybrids of cannabis Sativa or Indica with cannabis Ruderalis, which is a type of cannabis plant native to Central, Eastern Europe and Russia. Cannabis Ruderalis is lower in THC than cannabis Sativa or Indica. However, they are high in CBD which makes them a good variety for CBD users.

The first autoflowering cannabis had low THC levels, and therefore, they weren’t very popular. The flowers of the Cannabis Ruderalis autoflower regardless of the hours of light it gets (approximately within 2-3 weeks).

In order to get higher THC levels, cannabis Ruderalis is crossed with cannabis sativa. From this cross, we get a plant that autoflowers and that at the same time has higher THC levels than a standard cannabis Ruderalis plant.

New autoflowering strains have as much THC content as THC-rich cannabis Sativa and Indica strains. Autoflowering cannabis seeds have become very popular because of their ability to flower without depending on darkness. For instance, New autoflowering strains can reach up to 27% of THC.
