Would someone be so kind as to answer these questions:

1) At what point can I go 12/12 with them? How tall? How many nodes? Or what other criteria? Should I do 12/12 or some other time?

2) I have a switchable 400w light so should I use HPS or MH?

3) Any tips for determining sex? I have heard that males tend to show first? True? I don't want to have them under 12/12 any longer than needed so I don't want to wait for balls unless I have to.

4) Any other advice or tips on this subject would be greatly appreciated.

thanks in advance,

AK47 nice!, Wait till you have 4 nodes (about 6 inches) then go to 18/6 for a few days to a week,(so not to shock the babies) then switch to 12/12 to jump start the flowering. Now soon you will be able to determine what sex they are.Once you know I would go back down to 18/6 for a short while (again, so not to shock them), then to 20/4 for your vegging or 24/0. Your HPS wouldbe better for the vegging and your MH for the flowering.
I hope I have been of some help.PEACE.
