Growrilla’s Hydroponics System RDWC 2 Pots is a compact, recirculating deep water culture kit built around two 19 L grow buckets and a central controller. The system holds 45 L of nutrient solution and is driven by a Hailea HX2500 circulation pump rated at 650 L/h, with a Hailea ACO9602 air pump providing 7.2 L/min through air stones. Typical power draw is 17 W. The modular 32 mm push‑fit plumbing lets users adjust plant spacing (about 50 cm) and reconfigure the 80 x 65 cm footprint to suit 80 x 80 cm or 120 x 60 cm tents. Double‑layer pots (black inside, white outside) limit light ingress and heat. RDWC 2.0 was introduced in 2022 and is designed to expand to larger multi‑pot layouts.
