45 pack of individually wrapped starter blocks.
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.
Mini-Blocks sit in a tray (flat) without support for easy starting of seeds and cuttings. These Mini-Blocks are individually wrapped in white plastic to minimize algae growth. Remove wrapping and transplant into any loose media such as Growcubes or coconut fiber or leave wrapping on and set on top of a larger Gro-block. Packed in easy tear away strips, labeled with instructions.
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 — our improved stone wool substrate.
Keep it Real
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.
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.
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.
