Yes, I also had the same thought-that the bark is too "fresh", it is wonderful in aiding the novice to avoid overwatering/rotting roots, but it does little for capillary action for succulent type roots as phalaenopsis. I've noticed that the moss gives more uniform moisture and plump green and vigorously growing roots-I just don't trust myself with the water can, lol. The plants are doing fine though. The one I talked about in my original post is now in moss and the roots look good, slowly but surely the leaves will catch up
Thank you for your advice
