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,
