i always thought u could never tell sex at seed, thats very interesting. heres some info from the Dutch Passion website on how to gain more females. I quote "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."
