I'm about to start my first grow in a few years, and decided to try some auto blueberry with CFL's. Since i don't know much about autos and can't find too much information about them, i'm confused about which light spectrums to use and when? Do i go for 2700k from start to finish or 6500k for a few weeks then switch to 2700k? I've read that the best thing to do is use dual spectrum CFL's or use both through the entire grow, but the site was a little vague. Anybody have any suggestions? Thanks in advance.
