This document specifies a method for the determination of the dimensions and of the bulk density of pre-shaped growing media.

- includes solid, regular shaped, stable growing media sold, or which are ready for use, as a growing medium, where the dimensions and any corners are stable;
- excludes plugs;
NOTE - For the determination of the dimensions and the bulk density of plugs, EN 18250:-1 applies].
