The Deep Water Culture (DWC) hydroponics system is a soilless cultivation solution that provides plants with optimal nutrient solution depth, stable nutrient supply, and sufficient oxygen. This system eliminates common soil cultivation issues like uneven fertility and soil-borne diseases while allowing precise control of nutrient composition and environmental conditions.

Rectangular structure made of hot-dip galvanized pipes with waterproof film lining, typically 15-20cm deep to fully immerse plant roots in nutrient solution.

Includes reservoir (size varies by scale), water pump (selected based on system requirements), and corrosion-resistant PVC piping for solution distribution and return.

Foam board with customizable holes holds plastic planting cups (5-8cm diameter for leafy vegetables) that allow nutrient solution access to roots.

Air compressor and microporous aeration pipes maintain optimal dissolved oxygen levels for root respiration.

Maintains nutrient solution temperature (18-22°C ideal for lettuce), preventing root hypoxia in warm conditions.

The water pump circulates nutrient solution from reservoir to planting bench while the air pump oxygenates the solution. The system monitors and adjusts pH, EC, and temperature, returning solution to reservoir for replenishment as needed.

Deep solution layer (10-20cm) provides stable nutrient supply and buffers against temperature/pH fluctuations.

Oxygen gradient ensures aerobic respiration while spacious solution allows unrestricted root growth.

Transparent components enable visual monitoring; simple cleaning between cycles reduces disease risk.

Ideal for leafy greens (lettuce, spinach) and supports fruiting plants (tomatoes, peppers) during early growth stages.
