01SANDS & SOILS
Breathing space for every root system
Tucked beneath the soil line, these small spheres create a quiet infrastructure for growth. They sit within the pot, invisible yet essential, managing the delicate balance between water and air that determines how vigorously your plants reach upward.
Orku Hydro Clay serves as a versatile growing medium for hydroponics, indoor foliage, or mixed substrates. It suits growers seeking a stable, pH-neutral base that supports robust root development without the variability of traditional soil.
100% Hydro Clay (LECA)
10L Organic Hydro Clay Balls in resealable bags (Net Weight approximately 4Kg).


02MATERIALS
Expanded clay aggregate structure
Each ball is formed from 100% natural lightweight expanded clay aggregate, known as LECA. The manufacturing process creates a porous interior encased in a hard shell, resulting in a material that is both durable and breathable. This composition ensures the medium remains structurally sound over time while allowing air pockets to form throughout the root zone.

04PRACTICAL DETAILS
Ten litres of neutral support
The package contains ten litres of organic hydro clay balls, weighing approximately four kilograms net. Supplied in resealable bags, the medium has zero nutrient value and maintains a neutral pH level, making it compatible with a wide range of plant species. You can use it as a standalone substrate or blend it with other materials to tailor the specific texture of your planting mix.
