Grow More Siphon Mixer Injector

Make Fertilizing Easy with This Device

The Grow More Siphon Mixer Injector is a practical and easy-to-use solution for delivering liquid fertilizers and supplements while you water. Ideal for hose-end fertilizing, this device is designed for use with standard water pressure (30–90 PSI) and performs best with garden hoses up to 75 feet in length—shorter hoses provide optimal siphoning performance.

Simply screw the siphon mixer onto your hose bibb, connect your garden hose to the outlet, and drop the siphon tube into a bucket containing your diluted fertilizer. As you water, the mixer draws the concentrate into the water stream at a consistent 16:1 dilution ratio. A built-in backflow preventer ensures safety and compliance with most residential watering systems.

Key features and benefits of the Grow More Siphon Mixer Injector include:

  • Delivers nutrients at a 16:1 ratio directly through your garden hose.
  • Easy setup between hose bibb and hose; no special equipment required.
  • Compatible with most liquid fertilizers and soluble amendments.
  • Integrated backflow preventer for safe operation.
  • Ideal for foliar feeding and soil drenching in traditional hose-end applications.

Note: Not for use with drip irrigation systems. This mixer must be paired with an atmospheric Vacuum Breaker to comply with safety standards. When using organic fertilizers like Liquid Fish, we recommend pre-diluting and straining the solution with a reusable Strainer Bag to prevent clogging.

Siphon Mixer

Tried getting it to work but can’t, I’m sure it’s a great product once you get it working. I connected the vacuum breaker then the siphon mixer but no luck. I’ll keep trying, thanks.

Poor Quality

While functional, the plastic construction of this product makes for poor faucet connection. When moving my hose around the yard, the plastic threads would strip off and siphon would become detached from the water source.

Love this!

Easy to use and does a great job. No more filling up and mixing watering cans to haul through the garden over and over again. We have the best vegetable garden ever this year, using this system with our drip irrigation and soaker hoses.
First one we ordered broke. The company replaced it free, didn't even charge us for shipping the replacement. Great item with exceptional customer service! Highly recommend this product.

Siphon Mixer Injector

My last Siphon Injector was exactly like this (same brand & style) and still works perfectly, but it's covered with mineral deposits and stains from more than 5 years of daily use so I decided it was time to buy a new one. These Siphon Injectors are inexpensive and work well. I use mine with a 5 gallon bucket to inject fertilizer, fungicide, and pesticides into my hose for watering the orchids in my 26' x 16' hobby greenhouse. I searched the web over and Grow Organic had the best price I could find ...and they shipped it quickly!

Works great

I have two, I use them to remove Chloramine from my city water and adjust the ph. I can then add natural fertilizers at the end of the hose and not kill the biological material in it.
