2 plants 7 1/2in - 8 1/4in tall. About 6 weeks old from seed. No white hairs atm. (sex)16/8 lighting atm, will change to 12/12 soon. sound good? all comments welcome. thanx!

16/8 wont show sex.Either go 12/12 then back to 18/6 after sexing or pull a clone and sex it alone same way

pull two clones from each, wait for them to root, then flower the parents. thank me later.
