🔧 Technical data

💡 Why the RDWC PRO – 18 Pots is ideal for large indoor projects

🔁 Perfect homogeneity thanks to 50mm PRO circulation

All 18 pots are supplied evenly – pH & EC remain extremely stable even with many plants.

💨 Highest oxygen supply through PRO air rings

Result:

• massive root balls

• higher nutrient uptake

• faster growth phases

• significantly higher final yields

🌡️ Large water volume = natural stability

With up to 320 liters of nutrient solution, you can work consistently even with powerful LEDs and warm rooms.

🧱 PRO material quality

The double-walled pots prevent heat exposure and algae formation – perfect for professional environments.

🛠️ Application & Notes

1. Assemble system & connect 50mm PRO pipes

2. Install air rings per pot

3. Fill with 280–320 liters of fresh nutrient solution

4. Adjust pH & EC to target value

5. Activate circulation pump & air pumps (24/7)

6. Replace nutrient solution every 10–14 days

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

Tip:
A water chiller is highly recommended, as systems of this size run very stably and can absorb a lot of heat.
