18/6 light/dark.
Constant light cycle ie. same on/off every day.

I think more blue light gives more females.

Also you want you temps to be in the 70's.

I would start clonning as soon as you can.

Heres a quote from dutch passion seed company that says:

From literature and our own findings it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors. The environmental factors that influence gender are:


* a higher nitrogen concentration will give more females.
* a higher potassium concentration will give more males.
* a higher humidity will give more females.
* a lower temperature will give more females.
* more blue light will give more females.
* Fewer hours of light will give more females.

It is important to start these changes at the three-pairs-of-leaves stage and continue for two or three weeks, before reverting to standard conditions.

ok so when you mean 18/6 hours of light, does that mean, when you go to the dark hours it has to be completly dark..like putting a bag over the plant or something? Im doing 24 hours lighting for the first 2 weeks, then im going to start the 18/6 cycles..

oh and is a blue fluorescent light considered blue light?

So far as the statement, "Fewer hours of light will give more females"
I've interpeted this to mean something on the order of 17/7 for vegging.
Peace
