Auto flower light question

Can I just run it all the way through on 6500k bulbs without a big affect on yield? I have an NL auto in my veg cab on 18/6.

You can but youll see better results throwing in some 2700k, cfls are tricky and its hard to get big dense nugs without a bunch of 2700ks in there, atleast from my own personal experience.

Thanks man. That's what I needed to know.
