http://www.hydroponicsinfocentral.com – Hydroponics is simply the art of growing plants without soil in a nutrient based solution. Basically, instead of growing in soil, hydroponic plants are grown in vessels filled with nutrient rich water. Because there is no soil needed, hydroponic plants can be grown almost anywhere, regardless of weather or terrain.

The issue with hydroponics is that you will need to shop for "plant food" or nutrients and supplements which can be more costly.
I've watch about 5 "what is hydroponics" video so far and I like this one the best. It helped me better understand what hydroponics is.
