Growrilla’s Hydroponics System RDWC 12 POTS is a recirculating deep water culture kit built around twelve 19‑liter buckets plus a central controller pot. The layout uses four rows with 50 cm plant spacing, a 180 × 145 cm footprint, and is suggested for a 200 × 200 cm grow area. Total system water volume is 195 liters. A 1400 L/h water pump continuously circulates the nutrient solution to equalize EC and pH across all buckets, while an air pump rated at 60 L/min (3600 L/h) feeds twelve air stones for high dissolved oxygen. Double‑layer pots (black inside, white outside) limit light and heat. Push‑fit fittings allow tool‑free assembly and future expansion. Typical system power consumption is 55 W.
