Use where water pressure is 30-90 PSI, will work with a garden hose up to 75' long, however, it works best with a shorter hose.

  • Siphon mixer screws onto your hose bib, the other end attaches to your garden hose
  • Siphon tube drops down into a bucket of liquid fertilizer (or other material) and brings the concentrate up into the hose line at a 16:1 ratio as you water
  • A backflow preventer is integrated into the mixer

To use Organic Liquid Fish (F1335) with this siphon mixer we recommend that you dilute the Liquid Fish and strain the dilute mixture through our reusable Strainer Bag (E141).

Must be used with an atmospheric Vacuum Breaker. Do not use for drip irrigation systems.

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.

Probably a good item

I've not seen this item, but read the above review. What "Waist" of money complained about is a sympton of trying to use it with no flow at the end of the hose. If you pressurize it with the end of your hose sealed off, of course it will spray out the end of the pipckup tube. But that is not what it's made for. You should have all lines open when you charge you hose, and then it will suck water "OUT" of your bucket.

Waist of money

It sprayed water back into the bucket instead of pulling fertilizer out! It's very cheaply made
