Burr, I have several Dendrobiums that are in pots with chunks of Coconut husk. This the part that is between the coconut shell and the outside shinny skin. Two or three chunk per pot (2 for small pots and 3 for larger ones). Cut them to fit from the bottom of the pot to the bottom of the rim or about 3/4" of a inch from the top. Put your plant between the chunks and secure plant with stick till the plant attach's to the husk.Now I have heard that coconut has a lot of salt so you need to soak the chunks in clear water a couple time to help remove it. I am having no problems with this kind of medium so far I have only been growing for a year but my plants are doing great. When I go to re pot to larger size I will just transfer the existing coconut husk with plant and put Aliflor pellets around it.
