2700k = red spectrum (better for flowering)
6500k = blue spectrum (better for veg - although to be honest, I used a red spectrum for veg once and it didnt seem to make any noticeable difference)

A mix of red and blue is best, especially during the flowering phase, which is why other forms of lighting are better than CFL, because they emit both spectrums.

@Bigsby - I guess I am going to have to do a bit more research, but I might take you up on that offer.
