Even though we have eliminated the soil, plants still require a place for their root systems to develop. A hydroponic media is an inert substance that can provide some support for the root system that has no nutrient value. Almost any inert substance can be used. A few examples include sand, gravel, vermiculite, perlite, LECA (lightweight expanded clay aggregate) and rockwool.
