Grodan Plantop Plugs 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. Uniformity A fundamental aspect of the germination process is uniformity. It determines whether an even batch of plants is produced. Each Grodan plug is identical in density and fibre structure. The distribution of water, nutrients and pH is consistent. The result is...

Providing services for optimum germination results 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...

Consistent shape of the seed hole The seeding process can be performed using a variety of systems. Grodan has developed the optimum seed holes, available in various types of trays, to match each system. Conical Plug The standard version of the plug is the conical seed hole (see Seed hole diagrams), where the seed rolls to the bottom. A ring of stone wool surrounds the hole so the seed cannot roll over the edge and out of the plug. The holes are uniform in depth to ensure there is always sufficient and equal seed depth. In addition, there is enough space for the roots to develop. Deep Seed...

Vermiculite-free Funnel Plug The Grodan Plantop NG2.0 vermiculite-free Funnel Plug no longer requires the addition of vermiculite after sowing. This eliminates the dependency of propagators on an increasingly scarce resource. In addition, the vermiculite-free Funnel Plug brings several major advantages to the propagation process: • Keeps the work environment clean • ecreases pollution of the greenhouse water system D • aves on labour for cleaning and maintaining machinery S • Ensures a more efficient production process

Grodan stone wool growing media Grodan stone wool as a growing media offers many advantages. Thanks to the controlled manufacturing process Grodan stone wool is of a consistently high quality. The production process which takes place under an extreme temperature ensures that the product is clean and sterile. Its unique hydrophilic fibres give the growing media unique properties when it comes to managing both water content and electrical conductivity. The propagator and grower can administer the amount of water and nutrients the crops need in a very directed and controlled manner for optimal...

Plantop NG2.0 for propagators • Optimal steerability of water content (WC) and electrical conductivity (EC) • Fast and effective distribution of water and nutrients • More uniform batches of plants for delivery to growers • Optimal root development through the entire plug and block • Quicker and secured initial saturation due to lack of dry spots in plug and block • Better developed root system results in more healthy and vigorous plants. Plantop NG2.0 for growers • Outstanding uniformity within block and between blocks, enabling more accurate steering of WC and EC. • Better distribution of...
