ADVANCED Pot Herb Substrates

Modern and sustainable cultivation of pot herbs

Superior crop results achieved with perfect substrates has always been our goal. Therefore, we use only tried and tested alternative constituents to blend with high quality peat raw materials.
Due to their technical properties, wood fibre, perlite, coir pith and green compost have proved to be an ideal choice for this purpose. Pot herbs benefit from improved root growth, healthier plant development and also increased microbial activity in the root zone.

Moreover, we constantly strive to increase the sustainability of our substrates. The use of alternative constituents for the cultivation of pot herbs contributes significantly to this goal. They secure the reliability of our substrates and reduce substrate weight, which permits higher transport volumes. The result is reduced carbon emissions from transport and raw materials.

Our GreenFibre® fine is treated in special mills to achieve a specific medium-fine, very free-flowing structure. This ensures perfect mixing and even distribution in the substrate.

Substrates with GreenFibre® show a quick distribution of capillary water within the entire root zone, which is an important advantage e.g. in ebb and flow irrigation systems. It ensures easy irrigation management especially when growing with ‘dry-stress’ cultivation methods for compact plant growth.

In pot herb substrates GreenFibre® can be used at a share of 15 to 30 per cent by volume. When combined with more decomposed peat, the proportion of easily available water for the plants remains stable. Therefore, up to an admixture of 25% by volume, there are little differences in the irrigation behavior. However, the surface of the pots remains drier and the risk of root diseases is reduced. A nitrogen-based liquid feeding scheme in line with common practice leads to ideal growth results.


For more than 30 years we have been using TerrAktiv® green compost in substrates, since it is a natural, renewable and very efficient biostimulant with many positive effects for the crop:

  • Generates high microbial activity
  • Shows suppressive effects on soilborne pathogens
  • Stimulates root development and plant growth

The addition of 10 % by volume TerrAktiv® is already sufficient to achieve these effects.
