Not sure y u posted that link. Didn't really explain anything at all
If u want to root em outside. Get jiffy pellets or something similar. Cut clone bang it In glass of water to remove air bubbles. Then plant it. Snip tips of leaves. Fine mist the plants at morning and night or whenever dry.
Keep soil moist and keep a dome on. I get roots showing in about 4 days. Which is faster than anything I've read. And that's outside on a short light cycle.
And genetics really have not played a roll in anything. All my cuttings root very fast.
I've also had cutting root with out ever being misted I just left the dome on for a week straight and it was good to go. It's really simple don't over think it.
