I've actually grown to love cfls for veg. Since i dont need all that much power or light the first month it really cuts back and is more efficient(costs less). When i flower there is no comparison to my 400w hps, im in a small space so it really works to my advantage this way. If i were in any bigger of a space i would have invested in a 250w MH but even thats over kill for my set up. So in general i've just found what works for me, not necessarily for everyone.
