sounds like a plan m8 the cfls you have are they blue or red? if you got blues the mix of the lights blue cfl n red hps will give you stronger weed, i dont no the ins n outs but its sumfin to do with giving the plants both spectrums of light?
another thing the strains you got chronic n g13 might not react too well from going straight to flower, i dunno much about them but some strains do better than others straight from clone to flower.
Obviously all strains will produce more given some veg time might be an idea to see what they go like this run, but av your veg room up n running so your following batch will have been vegged.
and yeah cfls are wicked m8 ive used cfl and hps to veg b4 and much prefer the cfl gave me bushier plants and they just seemed that extra bit healthy.
