Aeroponics is a unique sub-division of hydroponics whereby no growing medium is required. Instead, the roots of the plants are sprayed directly with water rich in nutrients. Here are some of the advantages of Aeroponics which make it a better system over hydroponics
Aeroponics is simply growing your plants in an environment where their roots are sprayed with a nutrient mix using nuzzles on pipes instead of submerging the roots in a solution of the nutrient mix. The roots are suspended freely in the roots zone.
