Welcome!I live in Portland, OR, and we have pretty amazing varieties of soils around here that have a high mineral content, and some with high clay, as well.
California or GeorgiaWhere does the Miracle Gro Organic come from?
How big do you need? Petco has their $1/gal sale going on right now, makes it very affordable.I wish I had an extra tank to experiment with, but I'm a bit too poor at the moment. Has anyone done experiments with their local soil?
I am currently doing an experiment in a 10G with soil from my property paired with Nature's Care Organic (similar to MGOPM).
