Hey King, I would grow it all the way through, if that's your only plant, it will still be some killer smoke, and we have all smoked plenty of seeded mj, before.
A lot of people, keep the seeds like DW2, does, they are all female seeds, that you can plant again, they got a chance to be hermies too, but not all of them are. Just good weed to smoke, and you don't have to buy any more seeds. I know I can't tell any difference between a hermied plant, and any other plant, as for potentcy.
But I'm sure some pros, on here can. lol
