Ah! Another bit of information that I didn't know.
As you can tell I'm still puddying holes.
I can't tell you exactly where I saw that bit of info on to-be topped plants, as I browse through here and get lost sometimes in info and links. But I can tell you I DID see it, I'll try to find it.
But if I'm correct in saying that auxins DO move to the roots, (Are you saying that the auxins don't leave the terminal bud?) then having the lights on 18/6 would allow the auxins to move to the roots before you cut the terminal bud, saving that built-up hormone so the plant wouldn't have to produce more. (translating to less stress on the plant and faster pickup)
Has anyone tried putting clones under 13 or 14 hours of light? If the auxins do indeed move, then it might be better for them.
I agree that clones do need light to root. But maybe that's why people use 18/6 as opposed to 13 or 14. So the clones get a sufficient amount of light and a good amount of dark.
It's as though I'm hanging by a thread into complete persuasion. The one thread that is holding me up is the (once adamante) thought that auxins are the hormones responsible for new growth, and they move through the plant during different times of the day. If you're saying they don't move from the terminal bud ever, then that will release the snag.
I hope you can clear this up. I mean, this was a foundational fact which I have built upon. So it is very important for me to know the truth about this.
Maybe grass hopper can help us! He's the botanical genius, right?
