The word "deep" in front is only used to describe some water culture systems when the water depth in the system is deeper than 8-10 inches, then it can be defined as an actual dwc system. however regardless of the water depth, dwc systems are still water culture systems.. Deep water culture (dwc) is a hydroponic, and so also aquaponic, method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water.bubbleponics is a related method of plant production that involves a top-fed deep water culture system.. The water is released over the plant's roots and then runs back into the reservoir below in a constantly recirculating system. as with deep water culture, there is an airstone in the reservoir that pumps air into the water via a hose from outside the reservoir. the airstone helps add oxygen to the water..
Standard water culture systems and deep water culture systems (dwc) are about the simplest types of hydroponic systems available, and they are also very efficient at growing plants hydroponically. both hobby and commercial growers use this type of system, mainly because they are simple and inexpensive to build.. Before we look at a diy hydroponic deep water culture system, we should consider the disadvantages. first of all, the water temperature is difficult to maintain if you are using a non-recirculating dwc system; the water tends to get too hot.. It may be more than obvious, but this hydroponic system is called “deep water” due to the fact that the roots of the plants are submerged in water, and it refers specifically to the type of hydroponics where plants grow with the roots stretching out into a tub of oxygenized water loaded with nutrients..
