Oh and you SHOULD use both on seedlings, prevents stretching through the SARP effect, red light tells them to stop stretching. Just FYI

excellent info northern! I've been wondering about this. I'm about to start a new batch (2nd grow) and was wondering the effects of a pure cool blue spectrum as opposed to mixed. My first grow was started under 2700k because I didn't know any better. I've now got dozens of each. Any idea on what ratio of 2700k to 6500k is ideal?

Yes it should not be a problem. Mixing spectrums can be beneficial at times. I have mixed spectrums all the way through vegging and flowering and buds turned out great. As long as there are plenty of lumens, you should be fine. Plants just prefer a certain range during certain stages, but even using different spectrums should's be a problem if it is bright enough. Good luck!
