Professional 12-Pot RDWC System with 19-Liter PRO Pots & 50mm Circulation System – perfect for compact, high-performance indoor grows

The Growrilla RDWC PRO – 12 Pots (4 Rows) is a fully professional PRO-series recirculating system, optimized for especially homogeneous nutrient distribution, maximum oxygen supply, and compact indoor spaces.
With 12 × 19-liter PRO pots, a powerful 50mm PRO piping system, fine-bubble Air-Rings, and a very stable total volume, this RDWC system offers peak performance for LED setups, CO₂-optimized rooms, and all growers who want to achieve maximum yields with minimal space loss.

The 4-row configuration is particularly suitable for square rooms or grow tents, as it optimizes light distribution and access.

🔧 Technical Data

💡 Why this system is among the strongest 12-pot hydro systems

🔁 Homogeneous Circulation through 50mm PRO Pipes

A large pipe diameter ensures perfect flow →
no fluctuations, no deposits, no hotspots.

💨 Air-Rings: maximum oxygen performance

Microbubbles create ideal conditions for roots:

• huge root mass

• high nutrient uptake

• strong vegetative growth

• higher yields

🌡️ 200–230 Liters of Water Volume = Perfect Stability

pH and EC remain constant for many days – perfect for strong LED performance.

🧱 PRO Pots = Professional Level

Double-walled →

• prevents heating

• prevents light leaks

• prevents algae growth

A must for high-quality RDWC systems.

🛠️ Application & Notes

1. Set up system & connect 50mm pipes

2. Install Air-Rings & connect to air pump

3. Fill with 200–230 L of nutrient solution

4. Adjust EC & pH

5. Start circulation & air pumps (continuous operation)

6. Change nutrient solution every 10–14 days

7. Maintain water temperature between 18–21 °C

Tip:
In the 4-row configuration, 2–3 strong LEDs work perfectly (e.g., 600–800 W per fixture).
