✔ 50mm piping system – high flow, no blockages
✔ Constant circulation – stable pH and EC values throughout the system
✔ High oxygen supply – air stones / air rings for white, strong roots
✔ Approx. 60 liters total volume – ideal for stable conditions
✔ Space-saving in-line design – optimal for cabinets & small grow boxes
✔ Low maintenance & durable
✔ Perfect for LED setups, ScrOG & training techniques
💡 Why this system is so powerful
🔁 Recirculating DWC Technology (RDWC)
The nutrient solution permanently circulates through all 3 pots →
➡ even supply
➡ fast growth
➡ high oxygen uptake
💨 Explosive root development
Through air stones / air rings with fine microbubbles, this results in:
➡ high O₂ concentration
➡ strong, white roots
➡ high nutrient uptake
💧 Large water volume = more stable values
With approx. 60 liters total volume, the system remains extremely stable, even in warm weather or with strong LEDs.
🧱 50mm piping system
Allows high flow rates → no clogging, no hot spots, no sediments.

🛠️ Application & Notes
-
Assemble the system and connect the 50mm hoses
-
Connect air pump and air rings
-
Fill system with 50–60 liters of nutrient solution
-
Set pH & EC
-
Start circulation pump → nutrient solution circulates permanently
-
Change solution weekly (or every 10–14 days for stable EC)
-
Water temperature 18–21 °C for best results
Tip:
This system fits perfectly under a ScrOG net to get maximum yields from three plants.
