I went to a pet store and bought some loose substrate today. It is commercially made, but sounds like great stuff. It is ground very fine. The contents are virgin organic soil, peat moss, green tree moss, some orchid bark (not much, though), fine grain sand, and vermiculite. Sounds like everything but the kitchen sink. Does that sound good? Hope it works out. I put about four bags in and it came to four or five inches. What do you think?
