ARGEX® is pH neutral, is not compact and is reusable, making the product highly recommended and good for the environment. ARGEX expanded clay is used as a direct replacement for soil, mainly in hydroculture and hydroponic systems. ARGEX expanded clay allows the system to be stable in form and structure, while allowing excess liquid to be absorbed.
Hydroponic cultivation with ARGEX expanded clay is what is called a closed system. Expanded clay is inert, so the plants’ nutrition depends on providing a nutritional solution. ARGEX®, also supports plants, since its regular shape results in better aeration and lower moisture retention.
Another great advantage of ARGEX expanded clay in this system, is that it is very light.
