Grodan ImprovedGro Block Improved GR5.6 Large 3" w/Hole 3" x 3" x 4" Shrink wrapped/StripGrodan partnered with the Wageningen University and Research facility in The Netherlands and top growers throughout North America to identify the optimal stone wool substrate and irrigation strategies for specialty crops. The result of months of scientific research and trials is Grodan Gro-Blocks Improved with Grodan’s Advanced Wetting Agent. 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.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.

INGREDIENTS100% Perlite Procision Perlite Regular is cut with a 20 mesh screen leaving all material to retain #5. Perlite ore is a naturally occurring volcanic glass containing a small percentage of water. When that ore is introduced to tremendous heat the glass liquefies and the trapped water expands creating a remarkable and versatile material. In an ongoing quest to improve the quality of our products we recognized the opportunity to begin producing another of our own materials. Success at a new venture is never easy but we're really excited about the quality of our production.
