Cooler water, even oxygen, no air pump required The Alien V-System 4 Pot is a high-performance RDWC hydroponic system built around the JET-STREAM Vortex pump, which circulates and oxygenates the nutrient solution without a traditional air pump. Because the pump sits outside the header pot, less heat transfers into the solution, keeping water temperatures cooler, a key factor in preventing root rot and driving strong root development. In place of air stones, a vortex-style circulation oxygenates the whole pot so roots get consistent dissolved oxygen wherever they grow, while the large V-POT design gives a massive root zone for growers chasing big plants and dense harvests. It directly tackles the trio of hydro headaches, low root-zone oxygen, warm reservoirs and uneven feeding, that hold back yield, with wide free-flowing pipework delivering the same nutrient strength to every plant. Designed and manufactured in Britain from heavy-duty components. Key Benefits JET-STREAM Vortex pump oxygenates the solution with no separate air pump External pump placement keeps the nutrient solution cooler and lowers root-disease risk Venturi aeration for quiet running and lower power consumption Large V-POT root zones support bigger plants and stronger roots Even nutrient distribution across every pot via wide free-flowing pipework Sloped, full-drain pot design lets the system drain completely between feeds British-built with heavy-duty components How to Use Assemble to the manufacturer's layout, connecting the V-POTs with the supplied Dual-Flow fittings and wide tubing. Fill with water to the fill line in the header pot. Add hydroponic nutrients suited to your medium (coco, hydro or inert media) and mix thoroughly. Place net pots with media and plants into each V-POT lid. Switch on the JET-STREAM Vortex pump to start circulation and oxygenation. Monitor EC and pH regularly for optimal uptake. Drain and refresh the solution periodically using the full-drain design.
