| Over the years, I have seen orchids grown in marbles, broken up Coke bottles, Beer bottle caps, sphagnum moss, wine corks, bark, rocks, etc and even the extreme of a piece of barbed wire stretched down the center of a green house (just so the owner could tell people that he grew his orchids on a barbed wire fence)! Truth be known, if there was ONE medium that was universally better for everyone, there would most likely be only one medium used. Everyone's conditions are different. For me, Phals + moss = one dead plant. Yet, I use sphagnum for my Bulbos and they thrive in it. Most likely due to the Bulbos being very shallow rooted. In this case, I tend to agree with those saying to leave it alone for now. Unless you have grown the plant in the same mix for 12 to 18 months it is very difficult to make valid observations. |
