General HydroponicspH Control Kit For A Balanced Nutrient Solution

I’ve been using General Hydroponics pH Up and pH Down for maintaining the pH balance in my hydroponic nutrient reservoir, and I’m impressed with how reliable these products are.First off, the formulas are highly effective. A little goes a long way, which is great for precision adjustments without overcorrecting. Whether I need to raise or lower my pH, these solutions act quickly, giving me full control over the nutrient solution.One thing I really appreciate is how easy they are to use. Both products are well-labeled with clear instructions, making them beginner-friendly while still being ideal for experienced growers. They don’t cloud the water or interfere with nutrients, which is a big plus when you’re trying to maintain a stable reservoir environment.I’ve noticed that using these consistently has improved plant health. Maintaining the correct pH ensures that the plants absorb nutrients efficiently, and I’ve seen stronger growth and healthier root systems since adding GH pH Up and Down to my routine.If you’re serious about hydroponics, these are must-have tools. The bottles are durable and come in various sizes to suit any setup. Overall, I highly recommend General Hydroponics pH Up and pH Down for anyone managing a hydroponic system. They’re reliable, efficient, and worth every penny.

My shipment arrived slighly 'wet' inside the plastic bag and the paper labelling within; however, each indivdiual jar was properly sealed -- so... dunno where the wetness came from..The product itself works well; test is easy to conduct and easy to read with sufficient color variation to divine even 7 vs. 7.5 vs. 8 PH, etc.PH down is quite strong, a little goes a long way (about 1 capful pulled my 3 gal bucket down from 8.0 to 7.0 when measured again after 3 days).If I had a suggestion would be to also sell this kit in lower cost formats that do not include one of the PH up's or PH down (i.e. I dont really see myself using the PH UP, so therefore I would have preferred it not be included in the price).

I found this to be an excellent product. Word of advise go slow drop by drop and recheck. If not you will go in a circle. Add slowly. Mix first in a cup of water. Then add it in. I tested this against my ph pen and dam spot on. Or darn near it. It is reliable and effective. Test water ph before you start and air rate the water with a fish tank air pump and stone . Let water sit out 24 hours to remove chlorine. Test your soil ph . And test run off of soil. This will help to put the soil water in the ph zone you want. Price is not bad I had mine for months and it last a long time. Ty reading.

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.

This product does exactly what it says it does! efficiently too!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.

Why did you pick this product vs others?:great product and works perfectly for testing ph balance and getting it just right to use for water for my plants

This is simply the best product for what used for PHOPHM simple accurate very efficient amazing life for the money gives it great functionality with the pH down acid and base plus it comes with a tester tube reactive agent to test you ph levels!!!Amazing

The test kit works phenomenally. Super easy and a cheap way to accurately test your water pre and post treatment.Speaking of treatment, it only takes a few milliliters of the up/down solution to treat 5 gallons of water at a time. Literally, 2-4 ml to get 5 gallons of 7ph water to 6ph, mixes quick and stays the same PH during storage post treat.
