I'm afraid the pictures aren't working for me.
I have this one but I'm very unsure how to care for it (only had it since November).
Mine is growing in fine bark. I keep it in the house, but in one of the cooler rooms. It gets east sun which is quite dim so far since I bought it. I was told by the nursary that this one is best to dry out between waterings and that's what I've been doing.
I've been told buds can blast really easily. On mine the bigger bud when I bought it flowered, but the smaller one blasted.
Mine now has a new growth, so I hope I can work out how to care for it and keep that going
