"RSM" stands for "Standard seed mixture". This is a turf mixture that has been produced for a specific purpose and in accordance with the specifications of science and the Research Society for Landscape Development and Landscape Construction e.V. (Research Association for Landscape Development and Landscaping). Standard seed mixtures therefore follow certain standards and are intended to give lawn owners security and protect them from disappointment when installing new lawns.
RSM mixtures are generally more expensive, but you should never save money on lawn seed, as the subsequent trouble with weeds and grasses and lack of vitality is far too high.
RSM mixtures are divided into quality grades from 1 to 9. The turf seeds from our store are all RSM mixtures in quality class 8-9, which means that they have an extremely low level of contamination.
