My post included 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.
What got me to thinking was the line that said: Fewer hours of light will give more females. The reason I point this out is, I've seen a few debates recently about 18/6 lighting vs 24/0 lighting.
If the above paragraph is correct and true, wouldn't 24/0 produce more males?

I also posted this information a month ago...seems no1 seems to believe it. I decided to go with a schedule of 16/8 this go around as according to High Times would be the best light time for female plants. So far all my plants are females, and NO sign of hermies...YET!!
