you might get hermies.
i take cuttings and put them in 12.12
i never try to revert. When i pick a mother from seedlings i take all the females and take two cuttings from each one. And continue to let them grow long. The cuttings i take, i put in my flowering room, marked and tagged. In 8 weeks i determine which mom is going to be the keeper. Then i clone off of her and make more moms.
To skip all this just go buy 10 clones and make moms. They are already the top choice of a pro.
