I feel like one beautiful thing about feminizing seeds is that you can know exactly what traits your "male" brings (by flowering it and keeping a clone or revegging). Also it seems to me like there is so much variety of expression in F1 and f2 seeds, what I've been doing is popping lots of seeds, taking clones from all those pops, seeding all of those with the "male" i like the most from flowering, and then keeping the seeds from the clones of the plants that I liked the best. That way I know exactly what I'm breeding. Does add a month and a half to the run though.
