Mineral Soil Mix
This mix has mostly pumice, sand, and turface, with some bark as well. It dries out very quickly so it is great for plants that are very sensitive to extra moisture like lithops, cacti, and haworthia. Because of the bark, this mix dries even faster than my old 10% soil mix which used coir as the organic matter.
You can get a smaller 3.5 pint bag, or a full gallon for a better deal.
Ingredients: Pumice, Sand, Turface, Bark
