Abstract
The invention relates to a substrate composition, comprising substrate material and material providing structure and form arranged distributed in the substrate material, wherein the particles forming part of the structure-providing material are mutually connected at least partially by a binder. As a result of this binder it is no longer necessary to perform a temperature treatment, so that the associated drawbacks are avoided. In addition, the form-retention of such a unit is considerably greater than the prior art units. The substrate material is preferably formed by potting compost or another organic material. The binder is preferably formed by a pre-polymer reacting with water. This has the advantage that the polymerization takes place when water comes into contact with the binder. This takes place for instance when the binder is brought into contact with the potting compost.
