Product Description
General Hydroponics pH Control Kit accurately and efficiently measures the pH levels of your nutrient solutions, grow reservoirs, and the rest of your hydroponic system. pH control is essential for vigorous plant growth. Nutrient solution pH that is too high (basic), or too low (acidic), cannot be properly absorbed by plant roots. Incorrect nutrient solution pH can cause slow growth, sickly plants, and low yields. But General Hydroponics pH Control Kit is here to help. The kit contains everything you need to test pH levels and make adjustments so you can easily monitor and manage pH levels throughout your hydroponic grow. Kit includes: 8 oz. pH Up, 8 oz. pH Down, 1 oz. test indicator, a test tube, eyedropper, and pH Level Chart. To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5. 5 and 6. 5.

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.
The pH down solution is strong so start with the tiniest amount and check again. At three drops per test this bottle should last me a long time and for like $4 you can't beat it and I'll continue using this until I can get a pen.
What i didn't like is the company prints the color chart and instructions over top each other.
I would rather see the color chart on one side, (for us color-blind people) and the instructions on the other side. Have no issues with the chemicals just the color chart.
