Keeps PH stable in hydroponics nutrients solution

Excellent

Good

I think very effective when you need to manipulate the ph level of your water. Good products!

It's a Ph kit. It does what it is advertised to do and does it well. The test kit works great and often is quicker and easier to use than my digital meter. The color chart is built right onto the label of the test liquid so you can hold up the test tube and determine which color it matches or most closely resembles.

Great product! the test solution is super accurate, I double check with my Digital PH test pen every time and its always within .2+/- of the PH to what the color scale comparison says it is. very easy to use and if you're a note keeper like i am eventually you can just preset the ph with a measured amount before adding nutrients to get your desired ph outcome. if i had 4 hands i'd give it 4 thumbs up.
