Growrilla’s Hydroponics System RDWC 16 Pots is a recirculating deep water culture (RDWC) kit built around sixteen 19‑liter pots plus a controller. The RDWC 2.0 layout runs in four rows with 50 cm plant spacing and a suggested cultivation area of 240 × 240 cm. Total system water volume is 255 liters. Each pot is aerated by an air pump delivering 60 L/min (3,600 L/h), while an adjustable water pump circulates 300–2,000 L/h; combined electrical draw is approximately 116.5 W. Push‑fit plumbing allows tool‑free assembly and reconfiguration, and the double‑layer bucket design (black inside, white outside) blocks light to limit algae while reflecting heat. The system is designed to stabilize pH and EC across all pots and can be expanded within the Growrilla RDWC 2.0 range.
