Sphagnum Peat Moss and Advanced Green Fiber Substrate

Sphagnum moss is an ideal medium and soil substitute for starting seeds and growing plants in pots, trays, blocks, and containers. It is made of dried and decaying processed sphagnum peat moss. Its natural sponge-like structure explains why it can hold or retain more water than ordinary fiber-made potting media.

Sphagnum is a genus of 380 species of mosses commonly known as peat moss. The latter is formed of sphagnum decay under anaerobic conditions. With the right conditions, peat can accumulate to a depth of a few meters.

Sphagnum has a distinct structure adapted to the watery habitat it lives in. Its main body consists of stems and branches all coupled with leaves while its lowermost parts are dead and decomposing underground.

Sphagnum encloses two distinct cells types: Normal photosynthesizing cells and larger barrel-shaped cells. With its high porosity, Sphagnum soaks up water like a sponge.

Decayed, dried sphagnum moss is called peat or peat moss. It is used as a soil conditioner which increases the soil’s ability to hold water and nutrients by increasing capillary forces and cation exchange capacity. Peat is often desired when plants need increased or steady moisture content to flourish, mainly in nurseries.

Advanced blocking substrate: peat moss with GREEN FIBRE

For environmental and economic reasons, a new generation of peat moss was invented using a mixture of peat moss and green fiber.

Klasmann-Deilmann achieved the next milestone in blocking substrate development a few years ago thanks to a specifically processed fine Green fiber, with the primary aim  to enhance plant growth and irrigation management. However, other advantages were also noted in terms of truck loading volumes and carbon footprint. Since then, peat moss with green fiber has become the standard substrate in the blocking segment.

Green fiber is treated in special mills to achieve a specific fine, free-flowing, structure. This ensures perfect mixing and even distribution in the blocking substrate. Green fiber has led to a completely new and innovative concept for blocking substrates and thus opens up new possibilities for the future.

Advantages of using peat moss with green fiber

  • Ideal for pot stability and use in automatic transplanter
  • Improves root development
  • Faster water uptake
  • Use of green fiber up to 25% by volume of the mixture
  • Reduced weight, lower transportation  costs
  • Very suitable for a hydroponic system
  • Reduced carbon footprint

In addition to the above, Green fiber when added to pot soil helps absorb water quickly, creating water canals to easily distribute it within the pot. It also promotes rapid and healthy root development, while helping the plant to maintain excellent growth and vigor.
