sex???

Hi everyone, i still cant be sure about sex of this one, how long till i can tell for sure. Cant see any white hairs yet but there is no nads on it yet either. How mature does a plant have to be till it is obvious?

how old?.
indoor or out?.
well i carnt see any male sites. but mite be too early to tell.
what lites ect...

looks a bit leggy like a male, but lets hope not, its not dropping balls anyway.
if your growing outdoor it takes a lot longer, to flower.

Eight weeks and out doors. I can take a different photo but what part of the plant do you need to see??
