The substrate represents a layer or surface on which a typical hydroponic plant lives. In hydroponic cultivations clay pebbles and perlite are used massively. Like all substrate media, these are used to grow the plant in and supply air to the roots.
To cultivate indoor the ideal substrate must be used relative to the stage of the plants life cycle. A synthetic substrate, like Rockwool, is more indicated for the germination, whilst substrates such as coco or soil should be used for the cultivation.
