Air layer a whole branch or removing the whole branch and rooting several nodes could yield a plant that has multiple vertical shoots and a greater bud crop in shorter time. It could also technically be one plant and so ihelp to defeat plant limits that can cut yields unless lots of time is spent in veg and training.
I have used Espoma Seed starter to start cuttings in a solo cup with a 90% success rate. I speculate I should be able root a branch with a plastic bag like from a produce section at a grocer, an paper egg carton and some of the seed starter.
I think you could cut the bottom out of a couple egg slots and fill with seed starter scrape a few nodes train them thru the holes close and put in bag. Keep moist and root. Or do and air layer on the branch. either one.
