yeah different strains do different things. but people flower them from seed so i'd think if you had enough plants you could get a few females out of the deal. just depends on how long youre willing to wait.
I think it usually took me about 2 to 2.5 months till I got them to autoflower on 18, 6.
I just made my plant flower though after a month, it is a quick harvest. This thing is small though and I definately think it wanted to grow some more.
