Abstract
The present invention relates to a method and an installation for producing growth substrate blocks, particularly for blocks for cuttings for horticultural use, where loose substrate material is compacted in a forming chamber (18) and thus forms useable block bodies. With the present invention a compulsory moistening of the blocks with suitably heated water is performed, after which these are made ready for use almost immediately, so that an actual conditioning no longer is necessary or can be reduced considerably. The blocks can be moistened and heated from the inside to a desired temperature in a both quick and energy saving way. The moistener, which preferably is water, can contain various additives such as nutrients or the like.
