Literally, hydroponic gardening is the more enhanced version of greenhouse planting. This system utilizes water to grow plants instead of soil. According to many researchers, the deep roots of hydroponics can be seen in the history but it is more refined and practiced today. The art of hydroponic gardening can be witnessed in hanging plants of Babylon which is a proof that this technology is not new but has been adopted with many improvements in the practices and procedures. Clean water containing an abundance of oxygen and nutrients were used to keep plants breathing without having any soil contact their root structures. Other likely applications of hydroponics in the early centuries have also been witnessed within the Aztec culture.
