The block is robust and offers the right resistance for manual as well as automatic processing. The good distribution of water ensures optimum management of the air/water balance and the nutrient solution. Improved homogeneity Simple controllability of water and nutrients Optimum robustness and flexibility Ideal air/water balance Strong root growth through the entire block Ongoing development of the production process has led to perfectly balanced homogeneity in the blocks. The benefits to cultivation hardly need spelling out. Improved homogeneity Each Delta block is almost identical in density, fibre structure and robustness. It gives you uniform and qualitatively top-quality cultivation results. Simple controllability of water and nutrients Grodan Delta enables accurate control of moisture levels. Proficiency in water management is, after all, the key to the quality and yield of your plants. The efficient distribution of pores spreads water and nutrients evenly through the block. This ensures excellent controllability of the nutrient solution and pH value. To guarantee optimum growing conditions the block must not be too hard. The block provides the exact resistance needed to easily restore indented spots. Optimum robustness and flexibility In both manual and automatic processing, the robust and flexible fibre structure of the Delta blocks will ensure problem-free handling. Ideal air/water balance Because of variations in the small and large pores, the roots always have a sufficient supply of air and water. Water primarily seeps through the smaller pores whereas the larger pores provide enough room for the intake and release of air. Strong root growth through the entire block Grodan Delta stimulates the development of strong root growth during the cultivation process. Because of the balanced distribution and vertical structure of the fibres the roots all have the same level of resistance. Grodan Delta blocks are the starting point for uniform and perfectly controllable cultivation. They form the basis for vigorous and healthy plant growth. More information?
