Well, I checked these 2 in the aliflor today (similar to Hydroton) and the lasiantha was WELL ROOTED! I repotted it into a container with a mix of potting soil, orchid bark and aliflor.
Praetoria however has nary a root, still. So, I did the same thing and repotted in the same mix. We'll see....
Update on rooting: Praetoria and lasiantha
Congrats on lasiantha's roots!...be patient with praetorii...I waited 3 months and finally had success with Hydrponics.
Thanks for the update.

Good news!!!! I have killed them both so often I don't dare offer advise!!! But that is just me and I know others have an easy time!!!
