One week ago I took two rootless plants and began an experiment with them in live sphagnum that I received from a friend.
I have a Neofinetia falcata 'Shutennou' and a piece of Paph. Dollgoldi that broke off of the main plant. Both of them had no roots. The Neo has been in decline over the last year.
I put them on top of live growing sphagnum moss because I heard it is a miracle worker. I know this is not a controlled experiment, but I am getting results from two different species in only a week. I think I will let the photos do the rest of the talking.
