Grodan’s stone wool plugs show a high degree of uniformity, complemented by an ideal water and air balance. Their firmness, good shape retention and stability make Grodan plugs perfect for mechanical as well as manual
processing, including sowing, transplant selection and transplanting into Grodan blocks.
The way the seeds are sown has a direct influence on their germination. Germination depends on a multitude of elements including the position of the seed in the seed hole of the plug, the irrigation strategy and the climatic conditions imposed.
Following germination root growth can be influenced by other factors such as: the type of tray used, how the plug is located within the tray itself, and the effects of the greenhouse climate.
Grodan understands that it is crucial to provide professional propagators with the right tools and technical support to further optimise the germination process. User advice therefore comes as standard with all deliveries of Grodan Plugs.
Grodan Plantop Plugs are also available in a vermiculite-free version for cleaner handling and more precise seeding, while still ensuring consistent crop quality. Their advanced NG2.0 technology supports faster, more uniform root development for optimal young plant performance.
