New and improved stone wool substrate with advanced wetting technology from Grodan
Introducing Grodan Gro-Blocks Improved, a product specifically engineered to deliver real results for your crops, developed by plant scientists, researchers, and top growers.
A core component of the "Precision Growing" philosophy, Grodan Gro-Blocks Improved with Advanced Wetting Technology allow you to cultivate more uniform and high-quality crops while using less water and nutrients.
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.
