Growrilla’s RDWC Pro 24 Pots 4 Rows is a professional recirculating deep water culture system built around 24 double‑wall 19‑liter buckets arranged in four rows and a central controller pot. The PRO line uses 50 mm push‑fit piping to increase hydraulic flow and stability. Each site is aerated by cylindrical stones, and the circuit includes an inline filter and a float valve for connection to an external reservoir (not included). The system holds about 400 liters of solution, with plant spacing of 50 cm, a footprint of 185 × 275 cm, and a suggested growing area of 240 × 300 cm. Typical power consumption is listed at 125 W; air delivery is about 7,200 L/h and the water pump provides roughly 500–2,800 L/h.
