when do they show their sex

[kamakazi]

a mate of mines got a few plants growing outdoors in a shed and was just wandering when can we expect them to turn male/female? theres quite a few bunched together in a small area and there actually touching eachother so we're a little worried that the males are going to spread. how long once they show their sex does it take for this to happen?

I have found that they will start when there is 13 hours of daylight.
