# Ryuoh stone

Dense and nearly watertight, with white veins and sharp ridges.

## What the simulation uses

- Holds water: 1 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 3 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 2550 g/L (How heavy a litre is.)

- pH: 7.2 to 8 pH (How acid it keeps the soil.)

## Description
Dense and nearly watertight, with white veins and sharp ridges. It can make nearby water slightly harder and push pH up a touch.

Also called mini mountain stone.

Estimated, where sources were thin: look authored for the app; physical values estimated.
