Grodan Delta Hugo Block

Grodan Delta constitutes the basis for the uniform  and perfectly controllable propagation of plants, the condition to be  met for powerful and healthy plant growth. Each block has a virtually  identical density, flexibility and sturdiness, guaranteeing a uniform  distribution of the WC, EC and pH which in turn results in a uniform and  high-quality plant.

Grodan Delta guarantees plant propagators an optimum air/water  balance. The variation in small and large pores throughout the block  ensures that the roots are always supplied with sufficient air and  water. In addition, the water content of the block can be controlled  with great precision. The efficient pattern of the pores ensures that  water and nutrients are distributed uniformly throughout the block,  thereby offering excellent control over both the nutrient solution and  the pH. This promotes the development of a strong root system during  propagation. The uniform distribution and vertical structure of the  fibres results in the same resistance for each root, thereby ensuring  that the roots distribute themselves uniformly throughout the block.
