About Rockwool Mineral Fibers Inert Medium For Soilless Growing

Top 4 Benefits of Using Rockwool Starter Plugs
- Uniform emergence and plant quality - Grodan plugs have a highly uniform fiber 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.
- Improved air/water ratio - The unique fiber structure ensures an optimum air/water ratio and exceptional water and nutrient distribution. Thanks to the fast absorption of water, the plug’s fibers 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.
- Good firmness and stability - Grodan plugs are firm and maintain their shape during handling, and constitute a stable basis during rooting and the seedling initial development. They can be handled easily by hand during transplanting. This durability minimizes the risk of damage to the roots, enhancing uniformity and limiting losses.
- Efficient use of water and nutrients - The plugs’ steerability allows for greater control of the water content and the uniform fiber structure ensures consistent distribution and fast absorption when irrigating. That means less watering for you, and more efficient use of the water and nutrients, resulting in a more sustainable propagation process and lower costs.
