Growrilla RDWC 4-Pot Hydroponic System (2.0)

Professional Recirculating Hydroponic System (Recirculating DWC) for 4 Plants – Maximum Stability, Efficiency & Oxygen Supply

The Growrilla RDWC 4-pot hydroponic system is a powerful, modular Recirculating Deep Water Culture system.
Thanks to permanent water circulation, direct oxygenation, and large overall volume, this system offers extremely stable EC/pH values, a homogeneous nutrient solution, and optimal conditions for vigorous growth and high yields.

With four 19-liter hydro pots, a central recirculation system, a powerful water pump, and high-quality push-fit connections, the system is ideal for ambitious growers who expect professional results – with easy operation.

✅ Advantages at a glance

✔ 4 × 19-liter hydro pots – perfect volume for large, strong plants
✔ Recirculating DWC – constant circulation for stable pH & EC values
✔ Even nutrient and oxygen supply to all pots
✔ Push-fit connections – quick, tool-free assembly
✔ Opaque, food-safe containers – prevent algae formation
✔ Powerful water pump – ensures high flow & better nutrient distribution
✔ Generous system capacity – ideal stability throughout the entire cycle
✔ Modularly expandable – can be upgraded to 6 or 8 pots at any time

💡 Why an RDWC recirculating system?

Compared to classic DWC, a recirculating system offers:

🌱 More stable water values – large water volume + constant movement
⚡ Faster growth – nutrients are equally concentrated everywhere
🌡️ Less root damage – plenty of oxygen, no stagnation
🧪 Fewer pH/EC fluctuations – ideal for yield & quality
💧 Easier maintenance – one central control instead of four individual buckets

Perfectly suited for grow tents from 120×120 cm.

⚙️ Technical Data

🛠️ Application & Notes

1️⃣ Set up the system & connect push-fit pipes (tool-free).
2️⃣ Fill pots and recirculation tank with nutrient solution.
3️⃣ Place plants in net pots (e.g., rockwool, clay pebbles).
4️⃣ Activate water pump & air pump – circulation starts automatically.
5️⃣ Regularly check pH, EC & water level.
6️⃣ Clean the system between cycles & restart.

💡 Tip: With strong LEDs (e.g., 300–500 W), an RDWC system unfolds its full potential.
