    • Works well, great value for money.
I have used Dosatron systems in my greenhouse for years. I needed to order some parts, so I grabbed this injector as a full in until my parts arrived. It came and set up was easy, came with a rebuild kit and extra parts, all things I would have to buy separately from dosatron. It has been up and running smoothly for a week. It works so well I will leave in use unless something stops working. I will update review if that’s the case. Also seems to leak less than the dosatron, I believe this is because they include a wrench for the top. ... show more

    • Quality at a good price! Wish it had a bypass valve built into the design.
I purchase the Newtry fertilizer injection system to feed the flower garden growing around our household. It works as reliably as my neighbors $500 injection system in his commercial greenhouse! To winterize the system, I simply removed it from it's mounting bracket and brought it indoors. Next spring, I will change the plumbing to create a bypass line around the injection pump. It would be nice to have an internal bypass valve for those times when you want to wash a vehicle. ... show more

Great value unit. Will do exactly what it's supposed to do. Make sure to read directions and follow this advice. Plastic is not as UV resistant as more notable brand, plan to mount or store in full shade/dark, no sunlight. If mobile unit only bring out while using, store in dark. Scale on ratio adjustment isn't accurate. Must use TDS meter for precision. There is a max pressure. This is important. You may need a pressure regulator and PORV in addition to screens and check valves. See photo for 2 year old unit mounted in a controlled environment green house, previously subjected to 90psi operating pressure and 110psi surges. The case split. Unit on right installed 1/23 (along with regulator and porv) to replace split unit from 7/22. Unit on left, split, yet to be replaced also from 7/22. ... show more

    • A great value and solid performer
Very good price and quality seems good for pricepoint. Has been installed and running fine for a few weeks now. No leaks and no issues thus far. Adjustments allow precise control for dosing, so I can set it at 250ppm and it seems to dose consistently. The added bits for connectivity seem to not be needed for anything, but do appreciate the fact they sent along a repair kit for any probable or eventual failures that may be common for this type fertigation option. ... show more

This is my second one of these. I grow expensive and rare orchids in a grow tent. The first one I purchased after six months would not hold the proper fertilizer ratio. After nine months, even though I did all the appropriate maintenance, it started leaking and failing to inject fertilizer. I did all the necessary repairs, but it still did not work. So, I purchased a second one to hold me over until I could save enough for a MixRite. When I opened it, the caps over the threads were loose, and there wasn't any water inside. I didn't think anything of it, surmising they came loose during shipping. It made a horrible squeaking noise. I used the recommended vegetable, and the squeak went away. Two weeks later, it also stopped injecting and leaking. As I adjusted the ratio, the whole bottom stem part popped off and sprayed water/fertilizer into my mouth, eyes, and basement floor!! I disassembled the entire unit only to find that one of the O-rings had been replaced with an O-ring that did not fit, making it impossible for the piston to move smoothly within the shaft!! This was a used unit that someone had tried to repair using their own O-ring. They then returned it, and Amazon then passed it on to me!! I am so furious about this about this. I will not be buying another one, and I recommend you don't either ... show more

    • Easy to set-up, easy to install. Well made.
Fantastic! At 12psi on 1,000 ft of 5/8” drip line with 8” spacing this sucks up 15 gallons of solution when set to 4% in 2 hours.

Built this fertilizer cart so we can move it around. Having great results using MasterBlend Tomato & Veg in a 2 bucket concentrate adjusting our pH to 6-6.5 at the plant. We are also using it to dispense a 2.5 ph acidic solution so we get our regular water to 6-6.5 pH at the plant. We have our pump set at 4%. My only question is how reliable is this pump. ... show more
