Fertilizer Injector FAQ's

No, it’s actually very easy.   Just install it against a wall between the garden and your water mains or water tank.  The hardest bit is ensuring the right EC to your garden.   We show you exactly how to do this.   See this video

These devices have been used in large scale agriculture & farming practices for decades.     They are powered by water pressure.   As water enters through the inlet, it drives an internal suction action just like a toilet plunger.   This creates a vaccuum within the device which draws nutrient upwards from a tank below and injects this into the water flow at quantities between 0.4% to 4% of the total flow.

  • No electricity needed 
  • No pumps needed (if using water mains)
  • No reservoirs needed
  • Injects fresh nutrient every feed
  • No recirculation needed
  • Long lasting, commercial quality
  • Allows precise nutrient measurement
  • Automated & easy to maintain

This set-up is best used for larger scale operations which are cycling through more than 100 litres of water per week.   It means you spend less time managing your reservoir.   Because they rely on water pressure, they’re much more scalable then a water pump.  2 injectors are sufficient to power an entire 100 tower farm.   (Part A & Part B nutrient)

They come with a 1 year warranty on malfunction or parts replacement.   They also come with replacement seals which can be used after 1 year or so to extend the life of the device well past 2-5 years.   

Basically, this is a high quality venturi.   You can pickup small venturi devices for $20 but in our experience they don’t work!  It’s very hard to regulate the amount of suction and you end up wasting heaps of nutrient.   Also, the venturi’s we’ve tested are very tepremental.  It might work ok for a day, and then it stops sucking properly and your constantly second guessing if it’s working!    These injectors are made for commericial growers who need consistency and longevitiy.   Yes, they cost more, but they’re worth it.

Typically, the main issue is build up of mineral salt in the 6mm hose which extends into your nutrient solution.   This can be easily resolved cleaning the hose fortnightly with a wire or simply running clean water through it.   

For commercial farms, we recommend 2 x injectors.   1 for Part A & 1 for Part B.   However for smaller residential set-ups, simply use 1 injector and combing the Part A & B nutrient in one reservoir at an EC of 15.   This ensures no significant nutrient ‘lock-out’ or detrimental results.   See these results.  (All based on 1 injector and combined Part A &B at EC15)

Injector Configurations

Commercial

A Hunter X controller & electric solonoid set-up is connected to 2 x fertilizer injectors each drawing seperate Part A & Part B nutrients in precise configuration which can also be controlled remotely via an app on your iphone.

Residential

A simple water tap timer is connected to the water mains, with a single fertilizer injector which draws nutrient from a combined Part A & B reservoir containing a recommended nutrient concentration of max EC15-20 for optimal stability

Without any need for power, the fertilizer injector provides precise liquid fertilizer injection of dissolved nutrient with an automated dosing system designed to work acurately in various environmental conditions.  

No matter what flow or pressure input, the dose of the output solution will always be proportional and based on the configuration of 0.4 to 4% solution.
