Is my orchid healthy?

[Roberta]

Orchids need air around their roots, so they want a medium that dries out somewhat. Bark, cocoonut chips, etc. have lots of air space. It is much better to have a medium that dries out, so that you need to water more often - that fresh water flowing through the medium pulls air behind it - which is very important. Those roots want "humid air" not soggy wet.
