The pH Control Kit by General Hydroponics provides everything you need for testing the pH level of the nutrient solution in your hydroponic system. The pH balance is essential for stimulating vigorous plant growth. Vital elements in nutrient solution having pH that is too high (basic) or too low (acidic) cannot be properly absorbed by plants. Incorrect nutrient solution pH can cause slow growth, sickly plants and low yields.

this product is 3 bottles pH-up, pH-down and a pH test solution. (also comes with a vial to conduct the pH testing in AND a pipette which I thought was great, I ended up getting on before I opened the package assuming they did not provide one, but General Hydroponics really gives you everything you need to open the package and do testing RIGHT AWAY!)
I tested this on my hydroponic system with a calibrated pH meter hehe.....I wanted to know how accurate the test solution is. The test solution runs on a color scale, acidic being pink basic being dark green. The scale is located ON THE BOTTLE! so you never will lose it. As far as my basic testing concluded, the test solution is accurate; the color changes are visibly recognizable and comparable to the provided scale. 6.0 is yellow, 7.0 is green, and both of these matched my pH meter (in approximation, don't expect to perfectly get a 6.3 or something, this test kit is intended for keeping pH in a safe range, you could play with it and get exactly what pH you want with the assistance of a pH meter but I am judging this based on if a user DID NOT have access to a pH meter going on the test solution only.)
The acid solution is very effective, which is nice, you don't want to use a lot of product to achieve results and end up being in need of more solution spending more $$$. I suggest using this 1-3 drop at a time, waiting 20 mins or so based on water flow and size of your container, and doing another test. Don't over do it, always undershoot what you are aiming for; you will save product and also prevent too acid/basic solution......just be patient, eventually you will understand the power of the acid/base solutions and wont even have to second guess if you put too much in or not.
All in all, this is a must for a hobby hydroponic gardener or even a professional. Having a pH meter is nice, but some times the calibration may be off and having another testing method as provided in this kit is a good safety. I enjoy testing my solutions BOTH with the meter and the test solution because I know with out a doubt if my solution is within the correct pH range.
This will last probably a year or even more depending on how big your system is. Just use sparingly and maybe play with the testing solution with known known acid/base solutions so you can take not of what the ACTUAL color of the liquid will look like in correspondence with the pH. Maybe put some vinegar in the vial, drop some test solution and take note. you will see a bright pink color. add some of the base solution and you will see the color change in the vial....do this before you mess with your actual nutrient solution just to get a feel for the colors!
5 stars for: price, reliability, longevity of the product use and ease of use.
General Hydro is kind of the "big boss" hydro company and they really know what they are doing. Every product thus far I have purchased is good.
If you've never used pH adjusters like this before, be aware that it really doesn't take much!
They give you an eyedropper for a reason - unless you're working with a very large amount of water/nutrients/etc at once, you can sharply change the pH with just a few drops of one of these compounds. The pH Down (acid/orange bottle) is especially strong. Start small (try a few drops per gallon), mix or shake it up, test again, and adjust as needed.
