Do you need a growing media for hydroponics?

A growing media's water holding capacity and air porosity are crucial as it allows the plant's root system to have space to grow and 'breathe' – as the roots need water and oxygen to thrive. Drainage is also important as excess moisture can prevent oxygen from getting to the plant roots, creating root rot.

Can you use soil as a growing medium for hydroponics?
