Grodan GRO-Block Improved GR10 - Large 4" (4 x 4 x 4) with Hole - Unwrapped Strips in Carton, 144 Units (24 Strips of 6)

A core component of our "Precision Growing” philosophy, Grodan Improved Gro-Blocks with Advanced Wetting Technology allows you to cultivate more uniform and high-quality crops while using less water and nutrients, batch after batch.

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.

• PRECISION GROWING PHILOSOPHY - Grodan Improved Gro-Blocks with Advanced Wetting Technology allows you to cultivate more uniform and high-quality crops while using less water and nutrients, batch after batch
• OPTIMAL FIBER STRUCTURE - ideal 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
• UNIFORM WATER DISTRIBUTION - the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops
• SCIENTIFIC TRIALS - plants grown in these Improved Gro-Blocks had faster rooting-in, higher yields, improved quality, and less water and nutrient usage throughout the entire crop cycle

More About Grodan GRO-BLOCKS Improved GR10 Large 4" w/Hole 4" x 4" x 4" Strip

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 with Grodan’s Advanced Wetting Agent.

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.

New and improved wetting agent and hydrophilic technology greatly enhances the water characteristics of Grodan Gro-Blocks Improved giving even better water distribution over the height of the block. This results in greater plant development and steerability and more efficient use of water and nutrients.

Optimized wool structure allows for faster rooting-in and nutrient solution replenishment, all while the Gro-Block Improved maintains its structure, firmness, and rigidity throughout the growing process.

Note: This item is for commercial use and is packaged as bulk, without retail wrapping or labeling.
