Thanks for the information,

You sure have a lot more experience than I, since I've only had my 18 plants since germinating those seeds in June and potting them up in July, 2015.
At what point do you cut the tops off. I have one that is now 10" tall but none of the other are more than 6" tall. Most of mine are more like 4" tall. When you root those cuttings (and it sounds like you allow them to callous, like I do with plumeria), do you remove most of the leaves before rooting them?
By the way, I would never even attempt to root a plumeria cutting this time of year. I would wait until March at the soonest. Does that hold true with adenium? A plumeria cutting can be stored for several, even many months, and it will still root. I don't know about storing adenium cuttings.
