The benefits include: 1. The addition of oxygen to the plant 2. It cleans water of pathogens 3. Stimulates anti-chlorine action. These benefits results in healthier roots, increased nutrient uptake, thicker stems & bigger leaves.
Also known as the reservoir method or floating raft, DWC permits the crops' roots to be suspended in the nutrient solution. The air pump oxygenates the solution which keeps the roots from drowning. DWC should be keep away from light at at times due to algae growth. A primary benefit of this system is that there are no emitters to be clogged.
This technique works like a drip system providing a slow feed of nutrient solution to the growing medium using small emitters to drip nutrients directly to the roots of the crop. When the solution reaches the indicated level inside the bucket, the excess solution is directed into the return line back into the reservoir to be recirculated again.
