Grodan plugs are known for their homogeneity and reliability. They are the ideal basis for automated processing, uniform germination, and a high success rate with pricking out. The shape and firmness of the plugs are of a quality that makes processing significantly easier, whether that processing is mechanical or manual. Every plug has a uniform density, firmness, and fibrous structure. This means that the distribution of water, nutrients, and pH-value is also uniform, which has a beneficial effect on germination results.
The fibrous structure, predominantly vertical, gives the plugs the desired resilience. One practical advantage when pricking out is that the plug retains its shape, makes good contact with the block and guarantees fast root growth. A good balance between small and large pores in the stone wool ensures an ideal air to water ratio in the plugs. The fibrous structure creates a balanced distribution of feedwater throughout the entire plug. In short, the homogeneity, flexibility, shape, and firmness of Grodan plugs create the foundation for the optimum germination process and a uniform sowing result.
