Grodan 10x10x6,5cm Rockwool Propagation Cubes

Real Science

Grodan partnered with the Wageningen University and Research facility in The Netherlands and top growers throughout North America to identify the optimal stone wool substrate and irrigation strategies for specialty crops. The result of months of scientific research and trials is Grodan Gro-Blocks Improved.

Real Results

The result of this scientific rigor is Grodan Gro-Blocks Improved with our Advanced Wetting Agent. In the scientific trials, plants grown in these new blocks had faster rooting-in, higher yields, improved quality, and less water and nutrient usage throughout the entire crop cycle.

Real Improvement

These leading-edge blocks have the optimal fiber 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. Water distribution is more uniform throughout the entire block which is the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops.
