Opis produktu

Grodan Rockwool Cubes 7.5x7.5x6.5 cm with a 42mm Hole - a globally renowned growing medium - excellent target growing cubes - especially recommended for NFT flow-through systems. Dimensions: One cube: 75 x 75 x h65 mm. The cube has a 42mm diameter hole. Box = 384 pieces. Grodan Delta Cubes provide the basis for uniform and controlled plant propagation, a prerequisite for strong and healthy plant growth. Each block has virtually identical density, elasticity, and strength, ensuring uniform distribution of water content, EC, and pH, resulting in a uniform and high-quality plant. Grodan Delta guarantees plant propagators an optimal air and water balance. The variety of small and large pores throughout the block ensures that the roots are always supplied with sufficient air and water. Furthermore, the water content within the block can be controlled with high precision. The efficient pore pattern ensures even distribution of water and nutrients throughout the block, providing excellent control over both nutrient solution and pH. This promotes the development of a strong root system during propagation. The even spacing and vertical structure of the fibers creates the same resistance for each root, ensuring even root distribution throughout the block.
