Growrilla’s RDWC 18 POTS is a modular recirculating deep water culture system built around a central controller and 18 x 19 L buckets. The RDWC 2.0 layout ships in three rows with 50 cm plant spacing, a 120 x 275 cm footprint, and a suggested grow area of 150 x 300 cm. System water volume is 285 L. Each pot includes an air stone; the supplied air pumps deliver a combined 5,400 L/h, while the included water pump is rated at 300–2,000 L/h. Total system power consumption is 116.5 W. Push‑fit fittings allow tool‑free setup and easy reconfiguration, and the double‑layer pots (black inside, white outside) help block light and reflect heat. Designed and manufactured in Italy by Growrilla Hydroponics.
