Lava Rocks 20kg (10–20mm) – Natural Growing Media for Hydroponics & Aquaponics
Upgrade your grow system with this 20kg bag of 10–20mm lava rocks, a premium, all-natural growing medium ideal for hydroponics, aquaponics, and drainage systems. Sourced from volcanic stone, these lightweight and porous rocks offer excellent aeration, drainage, and root support for a wide variety of plants.
Lava rock is highly durable and reusable, making it a sustainable choice for deep water culture (DWC), flood-and-drain (ebb & flow), biofilters, or as a base layer for pots and beds. The rough, uneven surface of each stone (10–20mm in size) creates a stable, bacteria-friendly environment — essential for biological filtration and nutrient cycling in aquaponic systems.
