No offense, but decomposed granite is exactly that and always have been. At least as long as I have been around(long time)

Decomposed granite is naturally occurs, from wet freeze. The surface absorbs water then freezes, this causes the surface to decompose.

Crushed stone or rock, is just that also. Its man made, a crusher.

I agree, crushed stone is horrible for a monitor substrate. Decomposed granite is much better, but not great by any means.

Of course I have seen many monitors in nature in very granitic areas, but they do get the freedom of choice. They pick what they like. As there are all types of granitic soils. Cheers
