Overview
Grodan Gro Block Improved GR5.6 Large 3″ with Holes
New density and new hydrophilic technology equates to better water distribution and root development. Full saturation of the blocks with no dry spots, and improved EC control with less water, is achieved in the root zone due to the uniformly optimized wool resulting in sustainable water and nutrient use. Improved “re-wettability” will more easily increase water concentration in the substrate.
