How do i pre-flower to show sex?

I am starting my first grow from some bag seeds that I have and I wanted to know how I can determine sex at an early age.
I read something about pre-flowering but can't remember the process. It was something like pre-flower, then veg, then flower.
I will be growing in a homemade stealth pc grow box under cfl's.
If anyone can tell me the correct amount of time I need the lights on for pre-flower, veg and flower, I would appreciate it.

Preflowers will appear when the plant becomes sexually mature, even while still in veg. On average between weeks 4 and 6. I think somehow you became confused. Preflowers occur naturally in a plants grow cycle if allowed to veg long enough to become mature...

Veg 18/6 (on/off)
Flower 12/12

I veg for about three weeks before they go in flower...preflowers will show when they are mature enough.

you can force the by inducing 12/12 ntil they show sex then revert to veg if need be....some peeps advise against this....I have never had a prob...as long as you have stable genetics.......It worked for me. But waiting for pre-flowers is ideal.

Thanks for all of the responses, but I think what klonerone said is what I was referring to.
I think I will do 12/12 until I see sex, then yank any males before I veg.
 
i think the safest way is to keep veg till you want to flower. then remove the males and keep the chicks. flowering then reveging then reflowering might confuse your plants and end up being hermies and your whole efforts gone to hell
