01SANDS & SOILS
Inert spheres for vigorous root growth
These expanded clay spheres form the quiet foundation of any hydroponic setup, offering a stable bed for roots to explore. Their uniform roundness creates a porous landscape that breathes as easily as it supports.
Ideal for growers seeking consistent drainage and structural stability, this Orku substrate keeps liquid moving freely while holding plants firmly in place.
50L Hydro Clay Balls in bags (Net Weight approximately 20Kg).
02MATERIALS
Premium German expanded clay
Sourced from Germany, these spheres are crafted from high-quality expanded clay. The material is inert, meaning it does not alter the pH or nutrient balance of your solution, providing a neutral canvas for plant development without introducing unwanted variables.
FUNCTION
Efficient drainage and root access
The open structure allows liquid to drain quickly, preventing waterlogging while keeping roots accessible to nutrients. Because the clay is less susceptible to pests and disease than other solid substrates, it offers a cleaner environment for sustained growth cycles.
PRACTICALITY
Substantial volume for serious growing
The package contains fifty litres of hydro clay balls, with a net weight of approximately twenty kilograms. This quantity provides sufficient coverage for medium-sized systems, delivering robust structural support where it is needed most.
