Yeah it seems like 2x 4' flouros and 4x cfls are gonna be ok for you. So I would say pick up some more. Make sure you put the plants close to the lights also. It would also probably be easy to add some more lights like the ones you're using, down the line if you want.

The more and the better lights you have, generally the better output you're gonna get. Anyways, good luck :thumbsup:

You should also try just reading through random threads here and follow some grow logs. It would help to learn somethings, that's what I'm doing.
