Hydroponics Vs. Aerogarden
Hydroponic systems grow plants without soil, instead providing plants with water and nutrients by bathing their roots in a nutrient-rich liquid. You can choose between several types of hydroponic setups and, within each, different commercially available products. Does this Spark an idea?

Hydroponics
-
Hydroponics is a general term that includes any system in which you grow plants by providing nutrients using a nutrient solution. Hydroponic systems avoid soil, although some grow plants in an inorganic substrate, like vermiculite or sand, that support the roots without providing nutrients.
Aeration Method
-
One form of hydroponics, called the aeration method, suspends plant roots in a nutrient solution while bubbling oxygen around the roots. You can easily construct an aeration system with a mesh plant tray and aquarium air stone. The AeroGarden is a commercially available aeration system that can hold three, six or seven plants per garden.

Aeroponics
-
Another form of hydroponics, called aeroponics, differs from the AeroGarden by misting plant roots with a nutrient solution. Unlike aeration systems, aeroponic systems are more costly and difficult to maintain.
