These are going to be some broadstroke comments, not a dissertation...
Haze comes from the hazebrothers in socal in the 60s and 70s, who worked the original line before Nevile got ahold of the seed and worked it further in the Netherlands.
It's a linw of potent sativa hybrids known for its energetic effects with no ceiling. It's also a traditionally long flowering plant, which is why it was further crossed with Northern lights and skunk to make such strains as super silver haze, the piff, the cough, etc...
Furthermore, autos aren't a blank slate. You can't just cross a plant with an auto and get a true representation with auto flower time. No two autos breed the same, and alot of people are getting scammed into buying flavor of the month cannabis with the promise of shorter flowering times.
