Hey LK,
I got a giggle out of re-editing the photo, to indicate where I trimmed
the Headband to before I up-potted it into it's hempy bucket.
So, we were very much on the same page. :0)
What I was getting at is that when I apply any "X 2" to predict where the
stretch will end up should consider the height from the bottom of the bucket
more than the top of the hempy. (i.e. the buried stem counts as far as
the stretch goes!)
I did get a chance to take a few photos, including one that shows how I have
managed these plants so far.
Here is the top of my (very lovely) LA Confidential:

and there was the bottom.
You can see that I leave only fan leaves down where it matters.
I really appreciate your all taking the time and oversight.
JD
