Ph Up 250ml Growth Technology

Very happy with my purchase works great

Definitely changing pH of the water. Couple of drops it's enough. You have to monitoring the pH with pH meter or strips because only a little bit for 1L it's making pH very high. Good product for good price.

Great for making water the right ph for house plants

Great product, been about for so long for a reason. Reasonably priced and fast and efficient delivery on Prime. Also very straightforward to use..

Good product does what it's supposed to do... It is very strong so a drop or two is all that's needed.
