Grodan Improved Gro-Blocks

Leverage the benefits of products developed alongside plant scientists, that are specifically engineered to deliver real results for your crops. Grodan Gro-Blocks Improved with Advanced Wetting Technology — Grodan’s improved stone wool substrate.

Keep it Real

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 Grodan’s 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.

Grodan Gro-Block Improved

New Grodan Improved! Improved product at current pricing. New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume
Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.
