RE: Injector fertizer systems (Follow-Up #6)

Odd....but I just answered a similar question in another thread. I may be missing the details of what you're trying to setup....but...

For years I've used a drip irrigation system from dripworks.com. They sell a fertilizer injection system that I've also used for years. It's a tank with several hoses that allow the suction of the water running into your drip irrigation system to siphon the fertilizer into the mix also. You can adjust in several ways, but we use a low dose (low settings) that put a small amount of fertilizer into the mix every time we water. You can also set that higher and turn on and off the tank as needed. I think my 3/4 gallon tank was about $50 plus fertilizer.

In our greenhouse we've just setup a similar system with irrigation and misting. We built separate systems so we can mist our greenhouse with water only (no fertilizer) and irrigate WITH fertilizer. The tank also has screens to block particles from jamming up you injectors...and no pumps or electricity is required.

Simple or did I miss the details of your question?

Indyrose,
700 gal/min is free flow the pressure is not that high have been using it for 7 years with no problems they use pumps just like it for fountains and ponds. The mixture is as accurate as you make it. My setup cost me $100.00 including 100 sprayers and lines. The injectors are great but it would take 1 or 2 and sometimes 3 depending on what your using for fert. Never measured the pressure but I would guess it's maybe 20lbs at the most. They rate them by head pressure, the pump I use list head pressure 25'. that is the ability to life the water 25' up the hose. It all depends how often you want to measure out Fertilizer and how much money you have. I have 3 greenhouses and 3 systems like I describe. Good luck

Farmtek sells a very good injector for $229. They have a 5% discount code that I can e-mail to you that will get you 5% off the total price until 1/3 also. I wouldn't mess around with any of these janky do it yourself solutions (sorry to the other posters!)
I've used mine now for about 5 years and no problems with it at all.
You mix up your fertilizer 100 times stronger than you want it and it will mix it properly into your hose water. It's accurate at any flow rate you'd put it through from a drip to full blast. I did used to use those dramm venturi siphon type things before and they are a total waste of money. Not accurate at all, and clogged up easily.
If you'd like to come up and see our setup, e-mail me because we're just up in Muncie, not that far away.
