Cloning research

[Jason_mazzy]

Looking on new ways to try to get larger black pine cuttings to root so off to the web to research light spectrums. Of course the only research on cloning light spectrums is marijuana sites. So I am expecting a knock at the door anytime now asking about my growing tent.

Anyone know if there is certain spectrum that induces rooting?

Indoor growers traditionally clone with blue light. I haven't read anything scientific to back it up though.
