4-Bucket DWC Deep Water Culture Hydroponic System — 5-Gallon Buckets with Top-Drip Irrigation

Compact 4-bucket DWC hydroponic kit featuring 5-gallon PP planting buckets built to resist corrosion and temperature changes, so they keep their shape for long-term use. The system uses a top-drip irrigation arrangement for accurate, water-saving delivery to the root zone, allowing easy replenishment during active growth to promote efficient uptake. A dedicated air pump and air stones feed oxygen to every bucket through black feed air tubing, keeping roots immersed in nutrient-rich, highly oxygenated water for faster, healthier development. Designed for leak-free operation, the buckets include sealing rings, pre-cut water level tubes of uniform length, check valves to prevent backflow, and high-quality valves for improved sealing. The complete DWC kit ships with PP planting buckets, check valves, air pump, black feed air tubing, air stones, sealing rings, water level tubes, drip irrigation tubes, water inlet tubes, bags of expanded clay, air flow regulators, and assembly instructions for straightforward setup.
