Ph Test Kit, 1 oz

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.

Good product and value for the money you can test pH either with a pH tester or with the solution provided. This is a must have if you’re growing hydroponics will be purchasing again, though I feel this will last for a very long time.

The best arsenal I keep for correcting water Ph levels! GH delivers a very accurate and very dependable product every time. Highly recommend.

Easy to use and accurate enough for my herb plants

I've used this product for a long time, the stuff works awesome. Only issue is had was when it showed up the Testing liquid seemed to have leaked all over the inside of the bag making it nasty. It's happened before and will probably happen again, but the stuff works awesome so I'll keep ordering.

Works perfectly. Can test and balance PH after adding fertilizer to your water. Results in a happy plant that can absorb nutrients it otherwise might be missing. Yield increase in my experience.

works great

If you are struggling with yellowing leaves, stunted growth, or "nutrient lockout," the problem isn't your fertilizer—it’s your pH. This kit is the definitive "reset button" for your garden's health. Here is the expert breakdown. The Engineering: Chemistry Over Circuitry The beauty of this kit is its simplicity. Digital meters require constant calibration with buffer solutions; if you forget, your readings are a lie. The General Hydroponics kit uses a liquid indicator that provides a physical chemical reaction. It doesn't need batteries, it doesn't need "storage solution," and it never lies. pH Up (Base) & pH Down (Acid): These are professional-strength concentrates. In my 10 years of testing, the GH "pH Down" (the yellow bottle) remains the most stable and potent phosphoric acid-based adjuster on the market. It doesn't "rebound" as much as organic alternatives, keeping your reservoir stable for days. The Indicator Fluid: The bromothymol blue/methyl red spectrum is crystal clear. Whether you’re aiming for the "Peachy Orange" of 5.5 (Hydro) or the "Lime Green" of 6.5 (Soil), the color match is intuitive and nearly foolproof. Performance: The Science of Nutrient Uptake Plants are picky eaters. If your water is too alkaline, they can't "see" the iron or manganese. If it's too acidic, they can't "see" the phosphorus. By using this kit to dial in your water to the 5.5–6.5 range, you are essentially opening the "buffet line" for your roots. In my side-by-side tests, plants adjusted with this kit showed 25% faster growth than those given "raw" city tap water. PROS Absolute Reliability: No sensors to dry out, no batteries to die, and no "calibration drift." It works every single time you use it. Extremely Concentrated: A single 8oz bottle of pH Down can treat hundreds of gallons of water. You only need a few drops to move the needle. Complete Starter Set: Includes the test vial, the dropper, and the indicator fluid. It’s a "lab-in-a-box" that requires zero extra purchases. Shelf Stability: Unlike digital probes that have a 12-to-18-month lifespan, these chemicals stay potent for years if kept in a cool, dark place. The "Double-Check" Tool: Even if you own a high-end digital meter, every pro-grower uses this kit as a "sanity check" to ensure their meter isn't lying to them. CONS Subjective Color Reading: If you work in a dimly lit grow room or have color-vision deficiencies, matching the liquid to the chart can be tricky. (See my Pro-Tip below!) The Staining Factor: The indicator liquid is an intense dye. If you spill it on your carpet or white countertops, it’s permanent. Handle with care. Manual Process: It’s a bit more time-consuming than a 5-second digital dip. You have to fill the vial, add the drops, and compare the color. Overall Input The General Hydroponics pH Control Kit is a masterclass in functional utility. It is the foundation of a successful harvest. While it may feel "old school," it provides a level of certainty that digital tools simply cannot match for under $100. It is rugged, reliable, and technically flawless in its execution. Reviewer Pro-Tip: To get the most accurate reading, always check your color under "Daylight" (5000K-6500K) lighting. High-pressure sodium (HPS) or blurple LED lights will distort the colors of the liquid, making you think your pH is higher or lower than it actually is. Also, adjust your pH AFTER you add your nutrients, as most fertilizers will naturally drop the pH of your water! Who is this for? Hydroponic enthusiasts, Coco Coir growers, houseplant parents using Reverse Osmosis (RO) water, and any gardener who wants to eliminate "mystery" plant problems once and for all.

After using this PH Up&Down for a while now I can tell you this all what you need...easy to use and very fast to change the PH status in your water.... Super Recommended

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

Great product. Gave me accurate ph tests. Very easy to use and dependable results. Sometimes keeping it simple just works.

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.
