Grodan Improved uses a new Advanced Wetting Agent. These leading edge Grodan stone wool blocks have the optimal fiber structure and physical proper- ties for crop uniformity, more even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the entire block, and the greatest steering capabilities available. Water distribution is more uniform throughout the entire block which is the basis for a well-defined root system with higher capaci- ties for water and nutrient uptake to produce robust and vigorous crops. These benefits translate to higher yields, improved quality, less water and nutrient usage, and reduced sensitivity of the crop to diseases.
