My understanding is you can do this one of two ways. But I am new to this also.

1) You can clone one and then introduce the clone to HPS or flower cycle and see what it grows.

2) Most common method is to sex it during flowering cycle. Many posts on here and all over the net on what to look for. But its usually during the flower cycle.
