Deep Water Culture, commonly referred to as DWC, is just as the name suggests. It is basically letting the roots of the plant grow down into a nutrient solution or water culture.
DWC (Deep Water Culture) is the preferred system of choice for growing leaf lettuce, which are very fast growing and water loving plants, making them an ideal choice for the Deep Water Culture hydroponic system. Many commercial hydroponic lettuce operations employ this method, using floating Styrofoam rafts to hold the plant cups or just the plants themselves.
This setup can be as simple as a bucket full of mixed hydroponic nutrients (referred to as Nutes) with a hole in the lid to support a flower pot or it can be made large enough to support multiple plants. DWC hydroponics requires nothing more than a simple air stone and air pump to keep the nutrient solution stirred, oxygenated and fresh.
