Review: Device is intended for ph5-9, but working well (so far...) with ph11 - Installed 4 months ago and working fine. Our setup has it operating up to 10 hours a day, 5 days a week. At time of purchase the desertcart listing did not mention that the injector's instructions specify the ph should be between 5 and 9. The solution I need to inject is ph11 so it was annoying to find out only after it arrived that this was outside its specs. I decided to try it anyway; the price of the device is low enough that it was an affordable experiment. So far it has been doing well. If this continues it will be excellent value for money.
Review: Accurate mix rate, no problems. - Seems pretty accurate mix rate. I tested (by weight) at 4% and 2%. Came out as 3.8% and 1.7%. Looks like I set the gauge a little low (it's not a very precise marking system). I have not used it with fertilizer yet. no leaks so far (I've only put about 20 gallons through it). I just followed the priming instructions. I built a system with mostly brass parts along the bypass, then some schedule 80 and brass for the mix loop. I also included a drain valve. It's mounted on an aluminum 1.5" angle (painted green) on two U posts. Nice and sturdy, but still moveable with a little effort. I used an RV water pressure valve at the inlet so I can control the system pressure and included a meter at the outlet so I know the pressure going into the drip system.

### ⭐⭐⭐⭐⭐ Love this product
*by B***L on March 13, 2026*

This device has saved me a ton of money and time in my greenhouse. Raising over 6500 hanging flower baskets and with the correct fertilizer application to the flowers I can see a big difference over last year. Which means more money in my pocket.
