Need a bit Of help

Hey guys I am new to growing and ive got three plants going into budding faster then i can believe, but they are doing great, I have 12 perfectly beautiful clones all female coming my way and was wondering how many lights i am going to need, Ive got about 6 lights that equal about 500 watts or more, I will greatly appreciate all help and advice Thanks.

Well it depends what size containers are you in and how big do you want the plants?

I will take pictures of what i have going now, and my oldest girl is 2 foot and is in a great size pot.
