Growrilla RDWC 4 Pot Hydro System

Compact DWC upgrade for 4 plants – with active circulation for even supply

This RDWC system with four 20-liter pots is the ideal solution for home growers who want to take advantage of an active DWC (Recirculating Deep Water Culture) system. The recirculation continuously circulates the nutrient solution through all pots, ensuring stable pH/EC values, optimal oxygenation, and even growth for all plants. It's perfect for smaller grow tents or as a base for modular expansions.
