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.
