Plants don’t just grow in soil. As long as there’s sufficient water, air and nutrients available within reasonable temperature and pH ranges, plants will grow happily in anything from sand, expanded clay balls, coconut husks, fabric, or polystyrene! You can even grow plants in air, just as long as they are supported and their roots are kept in dark, moist conditions.

Did you know it’s possible to grow plants in aerated, nutrient-rich water? This technique, known broadly as “Deep Water Culture” is often regarded as “pure hydroponics.”

There are many different varieties of growing media. In order to know which one is right for you, first you need to understand how they work and what they do.
