Grodan Gro-Block Improved GR7.5 - Medium 4" (4x4x3.1)

Grodan Improved GR7.5 Medium 4x4x3.1 w/Hole Gro-Blocks 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.

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.
