CFL's will not produce what a hps bulb can do, you just cant compare it, its like a economy car vs. a Ferrari its just not comparable. Also CO2 is a waste using CFL as you need atleast 600-1000watts of light to properly introduce C02 for your plants to use it.

your plants look great so far and remember its weeks 7 and 8 that the plants start to really pack on the bud, be patient and no sampling.
