Features

1. Uniform emergence and plant quality.
Grodan plugs have a highly uniform fibre structure and firmness, guaranteeing excellent distribution of water and nutrients and promoting fast, uniform germination and root development. With this high quality plug, differences within and between batches of plants are smaller than ever. More uniform seedlings result in accelerated plant development, enabling faster harvesting.

2. Improved air to water ratio
The unique fibre structure ensures an optimum air : water ratio and exceptional water and nutrient distribution. Thanks to the fast absorption of water, the plug fibres become completely saturated when irrigated for the first time. The large pores allow for a permanent supply of fresh air and promote fast root development throughout the entire plug.

3. Good firmness and stability
Grodan plugs are firm and maintain their shape during handling and constitute a stable basis during rooting and the initial development of the seedling. They can be handled easily by hand during transplanting. This durability minimizes the risk of damage to the roots, enhancing uniformity and limiting losses.

4. Efficient use of water and nutrients
The plug steer ability allows for greater control of the water content and the uniform fibre structure ensures consistent distribution and fast absorption when irrigating. That means less watering for you, and more effective use of the water and nutrients, resulting in a more sustainable propagation process and lower cost.
