The Improved Gro-Block™ GR22.5 Jumbo from Grodan® is formulated with an advanced wetting agent and optimized wool structure to consistently deliver outstanding results for controlled environment indoor and greenhouse commercial grows.
These leading-edge Grodan Improved 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. This uniformity not only allows for more efficient and sustainable use of the entire substrate volume, but is the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops.
Grodan developed the Grodan Improved product line using scientific methods in conjunction with the world-renowned Wageningen University in the Netherlands. Grodan Improved was successfully trialed in the field by leading cultivation facilities throughout North America.
New density + new hydrophilic technology = better water distribution and root development!
