Nobody can do anything but respect that. Move at your comfort level. And completely understandable.
I made up a reading list for a student locally in a webdoc; give me a couple of days to locate it and there is tons of info available from states coop extension. It was pretty heavy on the culture and propagation end of things.
Hey I didn't realize you were talking that size. Of course you will have time to make it into a pot by freeze.
Right after flowering for the plant. I would pick the buds off the twig I was going to air layer though. Just to allow the tip buds, usually under calyx of the flower, to start growing.
Already got you covered with that reading list coming.
Good growing and good discussion thanks.
