Four-bucket RDWC kit for leafy vegetables

This recirculating deep-water culture system uses negative water pressure to move an oxygenated nutrient solution through four 20-litre planting buckets and a central reservoir. The top-drip design keeps roots submerged in high-oxygen water, promoting rapid growth and balanced pH and EC levels for leafy crops.

Check bucket spacing and power access before

Each bucket measures 300 by 300 by 380 millimetres and the kit weighs 10 kilograms, so confirm your grow area can accommodate the footprint and that a mains outlet is reachable for the 800 L per hour water pump and the four air pumps. The package includes 12 metres of black feed air hose and 1.5 metres of black feed and water supply hoses for flexible routing.

Continuous circulation maintains steady root-zone

The 800 L per hour pump and four air stones deliver constant flow and aeration rather than intermittent flooding, so dissolved-oxygen levels stay stable during long photoperiods. Sealing rings, pre-cut water-level tubes and check valves prevent leaks and backflow, letting the system run unattended for extended cycles without pressure drops or dry zones.

Questions about this item

Does the kit include the growing medium or do I need to buy clay pebbles separately?

The package supplies three to four bags of expanded clay, so a growing medium is included and no separate purchase is required for the initial fill.

Should I choose the four-bucket 20-litre version or a different capacity for leafy vegetables?

This model provides four buckets each holding 20 litres, giving 80 litres total capacity suited to leafy greens; no other bucket count or volume is offered for this system.

What does the 800-litre-per-hour pump rating mean for daily nutrient circulation?

The 800 L/h water pump continuously recirculates the oxygenated nutrient solution through all four buckets and the reservoir, maintaining balanced pH and EC levels throughout the cycle.
