What OneBakedWalrus wrote, is almost true.. Except for the little detail, that there's no sure way to get 100% feminized seeds, as of yet.
- There'll be a very small chance of gaining a male seed with the methods most breeders use.
I always get a little exited, when my plants start to sex.. There's nothing better than seeing it being a female, regardless of me only buying feminized and autoflowers. It's a sign that it's in it's preflower stage, You'll be seeing more and more of those hairs soon, and she should be flowering in a couple of weeks.
