Should this plant be bigger???

I've had this plant for atleast 4 , 5 or 6 weeks , i grew it from seed and im just woundering if it should be bigger then this??

Over a month old it should be much bigger than that, yes.

would more light possibly help it get bigger faster?

oh and i forgot to add that i have the light cycle on 18/6

What's the color temp of your CFL? What kind of soil are you using? Feeding any nutrients? How often do you water? What are your room temps? Humidity?
There are a lot of factors that contribute to early plant growth, not just light. Take a look through the FAQ and figure out if your environmental conditions are right on in order to make your plant happy.
