Growrilla’s Hydroponics System RDWC 3 POTS is a modular recirculating deep water culture kit with three 19‑liter grow buckets plus a central controller. The 2.0 design uses push‑fit plumbing so layouts can be reconfigured or expanded, while double‑wall pots (black inside, white outside) help block light and reduce heat. The package includes a 650 l/h water pump for constant recirculation and a V20 air pump (20 l/min ≈ 1200 l/h) feeding air stones in each pot. Total system volume is about 60 liters, with a footprint of 80 × 95 cm and a suggested 100 × 100 cm grow area. Power consumption is roughly 27 W. Designed for tents or small rooms, it balances pH and EC across pots and simplifies solution changes via the controller.
