Hydroponic techniques have been used for centuries, typically in areas that have very little rainfall. Hydroponics can be traced all they way back to the Egyptians. The word, Hydroponics, comes from the Latin word meaning, “working water”. Hydroponics is essentially the act of growing in media other than soil (typically with a water recirculation method). When people think of hydroponics they usually picture DWC (deep water culture) systems or NFT (nutrient film technique). Though these are only two types of systems, they are the most common in hydroponics. What about the simple ones? Flood and drain (Ebb and Flow) & the Drip System. These are easy, cheap, and work great! On a small scale or commercial level flood, drain and drip systems tend to be most common.
