I'm guessing for folks who desire the more sativa Dom autos... I really can only think of that as an "advantage" because it cuts down the long life of a truer sativa. Some Thai, Mexi, and Hawaiian sativa photos can go 12-14 weeks in flower. Every super auto I ever tried had Haze in it somewhere.
Also if you haven't realized... Sativa autos are very hard to come by that are hybrids or Sati Doms. Pure sativa autos are almost non existent now with all the breeding... Hell it's getting harder to find pure landrace sativas! Last 10 yrs have been built for speed... Which isn't bad but when you love that Sati High School high its getting harder to find..
