When the fluid flows through the venturi tube, that will bring vacuum. The fluid caused the vacuum is recognized as moving fluid. For the irrigation injector, the moving fluid is the irrigation water. The vacuum produced by venturi tube imbibe fertilizer and chemical into moving water.

I bought this Venturi, so that I could inject ozone into my shower stream. I connected this into the line going to my showerhead and hooked up the ozone generator for the gas injection. The Venturi worked as intended. The ends screwed to garden hose threaded fittings without a problem and the injection barb fits a quarter inch tube.

I’ve been using the Fertilizer Injector Tube Irrigation Venturi Injector 3/4" for a while now, and it’s honestly a game-changer for my garden. It’s super easy to install, and I love that it doesn’t require electricity—just water pressure to do its job. I set it up with my drip irrigation system, and it delivers nutrients evenly without clogging or messing with the flow. I even tested it in a small hydroponic setup for growing lettuce, and it worked perfectly to mix liquid nutrients into the water line. It does take a little tweaking to get the suction just right, but once it’s dialed in, it runs smoothly. If you're looking for a simple, efficient way to automate fertilizing, this is definitely worth picking up!
