Grodan - Granulate Fine (20kg Bag)

Grodan Granulate is a premium loose stone wool substrate designed to provide the ideal balance of water retention and root-zone aeration. Suitable for professional and hobby growers, it offers a clean, consistent and highly controllable growing medium for hydroponic, soilless and container cultivation.

Manufactured from high-quality mineral rock and formed into hydrophilic fibres, Grodan Granulate readily absorbs and distributes moisture while maintaining plenty of oxygen around the root zone. Its inert structure allows growers to maintain precise control over nutrient delivery, irrigation and growing conditions.

Grodan Granulate can be used as a standalone growing medium or blended with coco, perlite, expanded clay and other substrates to improve moisture retention, aeration and overall structure.
