Description Grodan Grotop slab rockwool growing medium The Grotop Master Grower provides the best quality soil for growing vegetables and flowers. In order to ensure stable plant growth and control of the entire production cycle, it is essential to ensure perfect conditions for the development of the root system. As a result of the special production technological process and its continuous quality control, Grodan carpets are characterized by stable, high quality, which guarantees the achievement of the best quality, high-yield crop. The Grodan growing field allows the water content to be controlled in the range of 45 to 85% so that the moisture and EC distribution within the field is even. This makes it possible to change the required moisture content on a daily basis (recommended daily fluctuation between 5-15%). During the growing season, it is gradually reduced in spring, then increased in summer and reduced again in autumn. With Grotop Master growing medium we can achieve maximum yield in all seasons. Rock wool, a hydroponic substrate with a light structure and weight – is made from the spinning of molten basalt rock, which is composed of fine fibers, so that cubes, blocks, crop boards and granular products can be made from it. Because rock wool and other rock or mineral wool used in horticulture are made from rock, they are considered by many to be organic products. Rock wool is a widely used growing medium in commercial horticulture for growing a wide variety of plants such as tomatoes, melons, cucumbers, peppers, strawberries, herbs and cut flowers; however, it can also be easily used by smaller hydroponic producers who want to enjoy the benefits of advanced root zone technology. The products made of rock wool are completely pathogen-free, as a result of which they guarantee a clean and healthy start to the new cultivation process. Grodan growing wool has excellent water retention properties (water storage capacity), which greatly facilitates the daily work of gardeners. By applying it, the best possible conditions for the development of plants can be ensured.
