What are these white dots on the fir bark in my low light orchid plants (Oncidium and phalaenopsis)? They don’t seem to be bugs and I rinse every once in a while with BT so I don’t think they’re bug eggs. But I could be wrong. They’ve been there for a few months. Is it just the fir bark breaking down?
Anyway the plants seem healthy but I just wanted to make sure it wasn’t something that I should worry about.
