Need help, I'm a first time grower

Ok. I put some seeds in a wet paper towel for four days to crack them, and they didn't . But I planted the in a small mcdonalds Sunday cup. And a few days later they sprouted, I have two tiny sprouters and they are about 2 inches from eachother. One is 1.3cms tall, and the other is .9 Cms tall. The one that is .9cms tall just appeared today in another cup and I switched it to the cup it is currently in to share the 14watt, but its a energy star fcl that is 14watt but = to 60watts. Currently its all I have. Now what I wanna know is if I can keep them under the same light, adjusting the light as it grows. What do you think will be its max hieght. And if I flower it right how much bud do you think it will produce?

Ty so much for reading!

Your light is essentially worthless beyond a couple of weeks of your plants' lives. In order to get a decent yield you will need approx. 100W of CFL lighting per plant. Your 14W just isn't going to cut it. Secondly, did you plant multiple seeds in one cup? Not a good move if you did.

just concetrate on keeping the thing a live and read some about what comes next..
