Positive developments on peat-free compost

In 2023, we have made significant developments in the field of substrates with reduced peat or even peat-free alternatives. We conducted numerous trials in collaboration with our clients, aiming to meet the widely-accepted agreements within the industry. Specifically, our goal is to integrate as much as 35% of circular raw materials into our substrates by 2025.

Additionally, we conducted experiments to meet the specific requirements posed by our clients' end-users - peat-free substrates

With the achieved results, we look optimistically towards 2024.

We wish everyone joyful holidays and a happy, healthy 2024. 

Below are some photos from the trials:

  • Cyclamen peat-free
  • Pansies peat-reduced
  • Fuchsias peat-reduced
  • Skimmia start peat-free and peat-reduced
  • Ellwoodii peat-free and peat-reduced
  • Goldcrest peat-reduced
  • Rooting of fuchsia cuttings peat-free
  • Primula peat-free

Research into mixing various raw materials

Due to the use of more and more different raw materials, it is important to keep a good grip on the production of substrates. For example, light raw materials such as wood fiber and heavy raw materials such as green compost have different behavior in the substrate.
Mixing these raw materials has an effect on nutritional content and air content. And this can have consequences for your cultivation.
