Improved drainage: Clay pebbles have a porous structure that allows excess water to drain away from the roots of the plant, reducing the risk of root rot and other moisture-related problems. This can be especially important in hydroponic systems, where plants are grown without soil.
A hydroponic stone substrate is the perfect growing media for use in hydroponic growing systems
The water storage is low but the air content of the bed and the drainability are very high. pH neutral types should be used.
The optimal supply of nutrients and oxygen to the roots is the main reason for faster and more vigorous plant growth in hydroponic systems compared to cultivation in soil.
Clay balls are easy to use and can be rinsed and reused frequently.
