What happens if i flower my plants when they are still seedlings?

Ok I am not saying I am going to do it, but what would happen if I did? I mean my biggest plant is only about 4 or 5 inches tall and about the same in its leaf span and I planted the germinated seed on March 1st so it is not even 2 weeks old yet, but its growing very fast and very well so I wondered what would happen if I changed it to 12 12 lightig now to induce flowering? Anyone know? I am anxious to see how many females I get.

Also side question here does anyone have a link to a good cloning post? I know how to take a clipping and what to do to get it to grow roots, but I don't know anything about how to maintain the mother plant or whether I need to keep one around permanantly for clones.

You would get about an eighth

they will probably double or triple in size by the end of flowering
