Sorry he ^ still can't type in rational sentences.

When the plant gets old enough it'll start to show its pistils if its a female (bud) or little balls which make it a male and worthless. This usually occurs in nature when the days shift to 12 hours of light /12 hours of dark. As it is now I doubt you're going to be able to keep it under a foot like you'd like. Usually bringing out door plants inside is frowned upon as well. For me in doors it took over a month from seed for my plants to display their sex.

I guess technically you could try to LST it to keep it short but I'd have to say good luck on that.... maybe you could transplant it to a new home outdoors somewhere farther away from your house were it won't be discovered.
