Professional 16-pot RDWC system for large indoor grows, maximum stability & high-end hydro performance

The Growrilla RDWC PRO – 16 Pots (4 Rows) is a large, professional recirculation system from the PRO series – designed for growers who need absolute homogeneity, enormous root power, and perfect pH/EC stability across many plants.

With 16 × 19-liter PRO pots, a 50mm high-performance circulation system, fine-bubble air rings, and a very large total volume, this system offers one of the most efficient and stable hydroponic solutions in its class.

The 4-row configuration is ideal for square rooms and powerful LED installations.

✅ Advantages at a glance

✔ 16 × 19L PRO pots – plenty of root volume for large, vigorous plants
✔ 50mm PRO piping system – maximum flow, no blockages
✔ Large total volume: approx. 260–300 liters – extremely stable pH/EC values
✔ Air rings per pot – finest micro-bubbles for explosive root development
✔ Double-walled PRO pots – light-proof, temperature-stable & algae-free
✔ Perfect homogeneity – all 16 plants receive exactly the same supply
✔ Ideal for large LED setups & CO₂ rooms
✔ Modular, expandable & low maintenance

🔧 Technical Data

💡 Why this system is among the strongest 16-pot hydro systems

🔁 50mm PRO Circulation = maximum stability

The large diameter prevents constrictions, sediment, and temperature zones.
All 16 plants receive identical nutrient solution quality – a huge advantage over systems with smaller pipes.

💨 Air-Rings: High-End Oxygen Supply

Finest micro-bubbles bring more O₂ to the roots →
➡ explosive root development
➡ faster vegetative growth
➡ higher final yield
➡ increased resistance to diseases

🌡️ 300 Liters Total Volume = natural pH/EC stability

Large water volumes buffer fluctuations and ensure constant values – ideal for powerful LEDs and warmer rooms.

🧱 PRO Pots with Double Wall

• No light leaks

• No algae growth

• Less warming of the nutrient solution

• Significantly better control over water temperature

🛠️ Application & Notes

1. Align the system on the surface (min. 2.4 × 2.4 m recommended)

2. Connect & seal the 50mm pipes

3. Insert air rings & connect to the air pump

4. Fill with 260–300 liters of nutrient solution

5. Adjust pH and EC values

6. Start circulation and air pump in continuous operation

7. Change nutrient solution every 10–14 days

8. Maintain water temperature ideally at 18–21 °C

Tip:
With a water chiller + 2–4 powerful LEDs, an extremely efficient indoor grow can be built.
