hey justaseed, ive got to say thats a nice looking setup you are running for just some cfl's...
blunt man, if you use between a 4100k and 3500k and enough wattage, you get nice veg growth without any strecthing(run 18/6)...when it comes time to switch over to flowering, you can drop down to the lower end of the spectrum as the redder light waves are better for flowering. (around 2800K or lower on 12/12)
