If you grow an aroid in sphagnum moss, like an Anthurium or Philodendron, and don't completely overwater it, but just keep the moss damp, not wet, it would grow fine. I have a lot of Anthuriums in moss, like this A. scherzerianum, being photobombed by Bulbophyllum Wilber Chang. Or, if you know how to do its you could grow a plant in semi-hydro in LECA or PON
