Ready for What’s Next: Peat-Reduced Substrates for Tomorrow’s Greenhouses

Investing in a new greenhouse or modernising existing facilities means planning for the future. One of the key considerations: which growing media will remain viable in the long term? Increasingly, the answer lies in peat-reduced or peat-free substrates – such as those in the ADVANCED range from Klasmann-Deilmann.

GreenFibre^®: A reliable alternative to peat
Limited peat harvests and growing environmental requirements are shifting the substrate market. The response: innovative formulations using alternative raw materials without compromising on crop safety. A key component is GreenFibre^®, an innovative wood fibre made for horticulture from sustainably sourced softwood. It supports optimal air-water balance, encourages healthy root development and contributes to a lower carbon footprint.

“GreenFibre^® is now the most important raw material next to peat in our ADVANCED Substrates – and it’s essential for sustainable, secure plant production,” says Anja Fritzen, Technical Adviser at Klasmann-Deilmann.

Tried-and-tested products for professional growers

The ADVANCED substrate line offers solutions across all segments – already proven in practice:

• Young plant propagation: The TS 3 fine with 20% GreenFibre^® is ideal for seedling trays and automated filling systems. It combines structural stability with excellent water uptake – perfect for sensitive crops and precision handling.
