Just to query some clarification-
I don't know what Black Diamond is, but Diamond Black is lignite, which is one of the ingredients in Fertiplant. I think this is what Shane meant to refer to? Lignite is a form of coal, IIRC.

If lignite is a form of coal, then could you use barbecue coal and smash it up and use as a substrate additive? interesting thought to ponder
