I don't know how true this is but when you're craving for a female (like I am lol) then I guess it can't help to try and follow some of these pointers. Got 'em from Dutch Passion

* 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.
