Grodan Loose Rockwool Flock (5 L) consists of fine-spun rockwool fibers optimized for propagation. It provides a balance of high water retention and excellent aeration, promoting robust root development in seedlings and clones. The loose format allows straightforward filling of propagation trays, pots, or blending with substrates such as perlite or coco coir. Sterile and inert, it reduces pathogen risks and supports reusability following proper cleaning. Naturally pH neutral after a simple rinse, it enables accurate nutrient delivery and pH control in hydroponic or soilless systems.
