Are there alternatives to peat?

It is practically impossible to imagine commercial horticulture without peat. Peat-free cultivation using rock wool (Grodan), coco fiber or bark compost substrate only plays a subordinate role. On the other hand, peat-free or peat-reduced potting soils are available with different proportions of substrate compost, bark humus, clay, wood chaff, wood fibers, coco waste or similar materials.
