An improved version of the original conduit that takes the principles of fluid dynamics and applies them to hydroponics, allowing water to flow more efficiently to the top of your 3Dponics system. The shorter pipe acts as the air intake (attaching to the air bubbler via rubber tubing); the longer pipe acts as the outlet (transporting water to the top of the system). For optimal performance, the Venturi should be placed vertically inside the reservoir, immersed in the nutrient solution. Bonus: The Venturi is smaller than the Conduit and therefore takes less time and material to print. If you have a dual outlet pump (e.g. HagenMarina 200), you can power two or more 3Dponics systems with one air pump.
