Which is actually better for growing Phalaenopsis orchids: sphagnum moss or bark?

Q: What are the pros and cons of using pure sphagnum moss versus pure bark as growing media?

A: Bark has one very biggest advantage, which is that bark, coconut husk and other media hold water poorly, so even if you water heavily, as long as ventilation is ideal, it will dry out quickly. It will not cause root rot, bud blast and similar problems due to excessive water. For beginner growers, this is undoubtedly like having a cheat code for growing plants. Of course, bark also has the following disadvantages:

1. It is difficult to estimate the moisture content of the medium by observing the surface, so it is not suitable for enthusiasts like us who grow many varieties.

2. Unlike sphagnum moss, plants are harder to secure, which is unfavorable for moving plants around

3. Plant growth is not as good as when grown in sphagnum moss

4. The medium has a shorter lifespan and decays faster

5. It is unfavorable for repotting, and the roots are easily damaged during repotting

6. Its water retention is not as good as sphagnum moss and it consumes water faster (for beginners this is an advantage, but for experts it is a disadvantage ^_^)
