Growrilla RDWC PRO 18 POTS hydro system

Modular RDWC system for large-scale plants with uniform nutrient distribution

The RDWC Pro system, with 18 pots of 20 L each, is the ideal solution for large-scale grows that require maximum efficiency and consistent growing conditions. The integrated return circulation continuously circulates the nutrient solution between the central tank and the plant pots – ensuring stable EC/pH levels, strong root development, and high yields with minimal maintenance. Perfect for automated grow rooms, CO₂ systems, and professional LED grow areas.
