I hear ya, but it seems like that would only work for a very small amount of soil, I mean, even with all the supersoil ingredients, the base soil(bagged potting soil) makes up a big majority of the final mix, w/o doing the math, its like 65% or more is the base soil. So that would be almost impossible for ppl that need the equivalent of a pallet of dirt. To do as your saying, it seems like it would be quite a task, your making the entire soil. You would have to go get a bunch of sphagnum moss, peat, coco, sand etc...on top of the amendments.
