Orchid mix, no kidding. And here I thought these things had to stay saturated - hence the self watering pots. Well, as dry as it is here, I just might need to keep it pretty wet..... sorry, thinking as I'm typing.
Heck, I can't even keep my orchids in orchid mix damp enuff! Big diff in our environments, huh, Lin? Our humidity was in the single digits last week, yikes....
