Efficient 8-Pot RDWC System for Medium-Sized Indoor Grows, Stable pH/EC Values & Strong Roots

The Growrilla RDWC – 8 Pots is a compact yet powerful hydroponic system in its standard configuration.
It offers reliable nutrient circulation, high oxygen supply, and stable conditions for eight plants – perfect for medium-sized grow tents and efficient LED setups.

With eight 19L pots, a 25mm circulation system, and proven RDWC technology, this system is aimed at growers looking for a powerful, low-maintenance, and cost-efficient hydroponic system.

✅ Advantages at a glance

✔ 8 × 19-liter hydro buckets – ideal for medium-sized grow areas
✔ 25mm pipe system – solid flow & stable circulation
✔ Large total volume: approx. 130–150 liters – very stable pH/EC values
✔ Air stones per pot – strong oxygen supply for strong, white roots
✔ Even nutrient distribution – homogeneous growth of all 8 plants
✔ Light & compact – easy setup & low susceptibility to errors
✔ Very good price-performance ratio
✔ Optimal for LED setups & training techniques like ScrOG/SOG

🔧 Technical Data

💡 Why this RDWC system convinces

🔁 Reliable Circulation

The 25mm lines ensure a consistent water cycle – ideal for stable nutrient conditions.

💨 Strong Oxygen Supply

The air stones create many fine bubbles →
➡ strong roots
➡ better nutrient uptake
➡ faster growth

🌡️ Stable Water Parameters

With up to 150 liters of total volume, the system remains stable, even if plants drink heavily or LED systems generate heat.

🛠️ Simple & Robust Design

An ideal choice for growers who want an effective and low-maintenance hydro setup without a PRO system.

🛠️ Application & Notes

1. Position RDWC buckets & connect 25mm pipes

2. Connect air stones & air pump

3. Fill with 130–150 L nutrient solution

4. Adjust EC/pH

5. Start circulation & air pump (continuous operation)

6. Keep water between 18–21 °C

7. Change nutrient solution approx. every 7–10 days

Tip:
This system works ideally with 2 medium-strength LEDs (e.g., 300–500 W per unit) over a ScrOG net.
