I'm trying to find some soil I can use with my WTF's for plants. I know all the important stuff like no fertilizers or styrofoam. The plant nursery sells potting soil that has nothing added to it, but it has this stuff called "perlite," which looks like styrofoam balls (it's about the same size). The nursery people tell me it's actually igneous rock, so it's organic. My question is, is this going to be safe to use or not?
