Deep Water Culture (DWC) is a hydroponic system where plant roots are suspended directly in a reservoir of aerated, nutrient-rich water. An air pump and airstone continuously oxygenate the solution, preventing root rot and delivering nutrients around the clock for rapid plant growth.
Key Facts
- Roots hang in oxygenated nutrient solution 24 hours a day
- Air pump and airstone are essential β dissolved oxygen prevents root rot
- Among the fastest growth rates of any hydroponic system
- Simple design with few moving parts; low maintenance once established
- Ideal for lettuce, herbs, spinach, and fast-maturing leafy crops
- Net pots hold plants suspended above or at the waterline
