Customers searching for volcanic stone for hydroponics are usually looking for a stable granular material that can support roots while providing air space and drainage. This article explains practical use in hydroponic systems in Saudi Arabia and makes clear that volcanic stone is not a substitute for nutrient management or irrigation control.
Green Grove Soil volcanic stone is a naturally porous agricultural mineral material used to improve root-zone physical properties. In granular systems, its value comes from structural stability, pore space, and drainage rather than plant nutrition.
Using Volcanic Stone in Hydroponics
In hydroponic systems that rely on a granular root-support medium, coarse volcanic stone can provide a stable substrate with useful air spaces. It should be washed thoroughly before operation to remove dust and fine particles.
This is different from systems such as NFT or deep-water channels that do not normally require the entire root zone to be filled with granular media. Material selection should follow system design rather than the general label “hydroponics.”
Why Is 10–25 mm the Main Grade for This Application?
The 10–25 mm grade creates larger spaces and faster drainage than finer material. The source positions it for grow beds, selected bucket systems, aquaponics, and other applications where a coarse, stable granular medium is required.
- Wash thoroughly before use.
- Manage irrigation and nutrition according to crop and system requirements.
- Test a limited quantity before a large commercial installation.
