DWC, acronym for Deep Water Culture, or deep water cultivation is a hydroponic cultivation technique which consists in growing plants in a highly oxygenated solution based on water and fertilizers.
Compared to other hydroponic cultivation methods, which use an inert substrate such as expanded clay, rock wool, perlite etc… for propagation
radical, in DWC the roots are completely (or almost) immersed within the solution which will act as both a substrate and a carrier for nutrients.
It is therefore possible to grow large plants with a minimum use of substrate, in fact a handful of expanded clay is enough in which to take root the young seedling and support it until the roots coming out of the pot will be able to develop in the solution. For this reason, deep water cultivation can be considered a cross between traditional hydroponics and aeroponics.
Drip system
A drip system is an active hydroponic system. This means that it uses a pump to feed your plants with nutrients and water regularly. It is also called trickle, or micro irrigation system. As the name suggests, the system uses small emitters to drip the nutrient solution directly onto your plants. A drip system is not unique to hydroponics. Such a setup is also widely used in outdoor gardens to deliver water and nutrients to individual plants. It works equally well with soil as well as growing media. In fact, the drip system was initially conceived for outdoor.
The system was developed to improve water efficiency in the outdoor cultivation of crops. It was later successfully adapted to hydroponics. Instead of spraying or running water to the plants, the emitters secrete the liquid in a slow dripping action. This ensures that the system uses very less water. You have a high level of control over the amount of water and nutrients supplied to the plants. The system uses a network of feeder lines to deliver the water to the plants.This kind of setup is best suited for large growing operations. This is the reason for commercial operations preferring drip hydroponics over other systems.
