Deep Water Culture DWC


Deep water culture (DWC) is a hydroponic growing method that involves the production of plants by suspending the roots in a solution of nutrient rich, highly oxygenated water.


Commonly this method of growing involves the use of plastic buckets which contains the nutrient solution oxygenated with a aquarium pump and airstone. The plant would be contained in a net pot suspended from the center of the lid of this bucket and the roots suspended in the nutrient solution. Because of the high concentration of oxygen in the water the roots are able to remain suspended in the solution without the risk of drowning the plant.


Although the plants absorb vastly more oxygen directly from the air than from the oxygen dissolved in water the Deep water culture system allows plant roots to absorb large quantities of oxygen while also allowing the uptake of nutrients. This leads to rapid growth throughout the life of the plant.


Variations of the DWC method include Recirculating DWC or sometimes called Under Current DWC which can link multiple buckets together that share a single resevoire. Buckets are linked with pipes or hoses that circulate the solution using a water pump. This system allows for the controle of variables such as PH, PPM and air content from a single point which can greatly reduce the amount of time tending to individual buckets.
