# Coco husk chips

Springy chunks of coconut husk. Airy and slow to rot.

## What the simulation uses

- Holds water: 27.5 % by volume (Water it keeps after draining; the rest runs down to the drainage.)

- Pore space: 88.5 % by volume (Room for air and water between grains; low means roots suffocate when wet.)

- Weight: 125 g/L (How heavy a litre is.)

- pH: 5.5 to 6.8 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: 3 to 5 years (How long it lasts before rotting down to fine soil.)

- Nutrients: low (Plant food it brings.)

- Presses down to: 40 % of its loose depth (How far pressing can pack it, keeping its weight.)

## Description
Chunky pieces of coconut husk, a favourite in tropical vivariums. Water drains through fast, and the chips last three to five years before breaking down.

Also called coco chips, coconut husk.
