Practically every "Potting-Mix" and "Potting-Soil" is soil-less. It is too bad so many of the manufacturers of it (Miracle-Gro for example) uses the term "soil" on the label. Only when you get into the "Miracle-Gro Garden-Soil", "Black-Kow", and the like, will there be "dirt" involved. At least that's what I understand.
