I was thinking mineral mix as in fertilizer, as opposed to soil-less potting media.
The only thing I can think of in the use of inorganic matter is in hydroponics. Certain kinds of systems use rocks or other type of anchoring for roots. But the plants are fed organic as well as chemical fertilizers in order to produce.
Now that's a thought for experimenting. I might try it...pumice and vermiculite to anchor and provide moisture, and give adequate nutrients in a weak, daily liquid fertilizer regimen.
