Another theory is that the early genetics came from the first oilseed hemp variety called Finola, which was developed from Russian stock in Finland during 1995.
[7] These early hybrids with large amounts of C. ruderalis genes[8] were lacking some of the finer qualities of high grade cannabis strains available.
[10] Because the effect was weak when consuming it due to its low THC levels, autoflowers weren't popular among recreational users.
[12] Breeders started developing ruderalis hybrids that had high THC or CBD levels and only needed around 9 weeks to completely mature.
These hybrids became known as autoflowering cannabis, for its ability to flower automatically without depending on darkness, like normal photoperiodic strains.
Further complexities with stabilizing autoflowers has previously led to non-autoflowering and low quality strains making it into the market.
