I have a question, with my P1 parents who are stabilized can I do 12/12 from seed to sex them and hopefully find males and females or should i grow them out? I know that with the ensuing generations will need to be grown out to find the differences between them.
It would be hard to tell which males and females are good unless you grow them out so that you can make your F2. You need to select the best ones to stabilize the genetics. If you just throw them 12/12 you will not have a good idea how they perform in veg or pest resistance. So it is best to veg them out and take clones for sexing. You can take fresh clones and run them 12/12 while they are rooting.
