Grodan Max Rockwool is the latest generation of Rockwool developed in collaboration with Wageningen University and selected medical facilities. In South Africa, Grodan Max is exclusively available to high-tech SAHPRA approved medical facilities. Like all Grodan products, Max is also made from natural basalt rock, but the brown colour of the wool is because Grodan have developed a new wetting agent and innovative sugar-based binder, and this offers the user to grow in a more ”green” way.

Grodan Max wool has optimized properties, with more even water retention capabilities, improved root aeration, more even EC distribution and the wool allows a grower to implement precision crop steering through more aggressive drybacks. Compared to improved wool, the superior properties of Grodan max present the opportunity to reduce water and nutrient use by up to 15%, to increase root biomass by up to 10% and increase yields by 5%.
