New and improved wetting agents and hydrophilic binder technology greatly enhances the water characteristics of Grodan Improved 4x4x4 , 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. The optimized wool density allows for faster rooting-in and nutrient solution refreshment, all while the Gro-Block Improved maintains its structure, firmness, and rigidity throughout the growing process.
