yes it is totally possible depending on the plants. The plants that are true epiphytes which would normally be growing up in a tree than in the ground do very very well in moss. I grow my Anthurium veitchii's, my Anthurium warocqueanum, many of my Anthurium spectabile young plants, my Anthurium metallicum, Anthurium cutucuense, and others in moss in big 14" coir lined baskets. This method allows a the plant a full ability to make adventitious roots that hand out of the basket, these would normally attach to something, but they can just dangle if humidity is high enough. even the Pachyneuriums (the bird nest types) will grow in moss or just orchid bark....they make a lot of surface roots that tend to be brittle and they do NOT like to be disturbed, and, once they get really huge, its yard to repot them. They would normally be perched up in trees on sturdy branches, but few of us probably have the ability to put them up there logistically. When I planted big Schlectendalii in the ground 15+ years ago, I made a hollow in the edit and willed it with orchid bark. I can take a picture of the roots now, all these years later,,,they are a big nest above the ground which is where they like to be
