# Driftwood
Reusable

Dense, weathered wood that lasts. Can tint water tea-brown.

## What the simulation uses

- Holds water: 25 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 40 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 900 g/L (How heavy a litre is.)

- pH: 5 to 6.5 pH (How acid it keeps the soil.)

- Mould risk: low (How much fresh food it gives white mould; high-risk soils fuzz over in the first weeks.)

- Breaks down in: 5 to 20 years (How long it lasts before rotting down to fine soil.)

- Nutrients: low (Plant food it brings.)

## Description
Hard tropical bog wood that sinks and can last decades before it rots. Its tannins nudge the soil slightly more acid. Moss and epiphytes mount nicely on its surface.

Also called Malaysian driftwood, bogwood.

Estimated, where sources were thin: density and pH drop not measured on cited pages.
