Solo-Cup Grow

So I've decided to take on a task as a new grower ><. I want to see how solo-cup plants it will take me to yield a dry oz. I've got about 7 seeds in the ground right now, and probably another 7ish going in tomorrow. I will be putting 3 plants into slightly bigger pots, but leaving the rest inside of the solo-cups. Just out of curiosity, how many CFLs do you think it'll take to run 3 2ft plants and 7-8 solo-cup plants? I have 4 42w bulbs in there now along with 2 25w(or around 25w) bulbs. How many more bulbs do you think I need to achieve a decent yield? I don't want a "Great amount of light" Just enough to somewhere around a qp out of all of them.

If I'm being way to un-realistic please tell me. I do know solo-cup plants are possible as I've seen pictures of them, I just don't know how hard it will be to achieve success.

the bigger plants would do well with 3 42 watt lights each, 1 on top and 1 on each side, the solo cup can probably work with 2 25 watt lights each, just make sure they are close enough or it wont work very well. If you want great amount of light it would probably be 50% more than what I stated.
