First Grow Veg?

this is my first grow, i am growing from bagseed some good mids. I am planning on growing these then getting some good seeds. Get experience first. They are about three weeks old and are about 9 inches tall. I wanna get a good yield but dont want to grow forever before starting my good buds. About how long should i veg for to still get a good yield. I have 6 plants right now but who knows how many are female. And mids will produce more weight then real good seeds right?

well i'd veg them till they show there own sex's far as "mids" not sure wat u mean

its midgrade weed. its not dirt but its not crucial bud. it had seeds. and not lots of red hairs

ahhh well keep growing and learning
