That's what I envisioned when I first heard about it. Like growing Peace Lilies in a glass vase with a Betta Fish swimming around in between the roots (Am I showing my age?). I did that once and still have the vase and thought growing orchids that way would be cool. But when I started researching, I couldn't find anything about it.
You may have started in the Orchid forum and I was just lost and confused.
