The result of months of scientific research and trials is Grodan Gro-Blocks Improved with our Advanced Wetting Agent. These leading-edge blocks have the optimal fibre structure and physical properties for crop uniformity, more even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the entire block, and the greatest steering capabilities available.
