Well, Happy Belated New Year to everyone
Haven't been watching this forum, so I have a Lot of reading to catch up !
Wanted to mention I've found a 'Good Cheap Grit' for adenium soil mixes: Aquarium Gravel ! (may not be the 1st to use this, but it cheap) If you want you can even color coordinate the gravel to the blooms.
I prefer the Natural color browns/tans.
