Tried and True.
I've been using this for years. It works not just for hydroponics. I have really hard water where I live and I use this to adjust the pH before watering my plants. It really makes a difference.

Works great
I use this alot to ph balance my water for my plants. I like to keep my water pH around 6 and this helps a lot to balance it out before adding nutrients to the water supply.

Essential Buffering for Robust Plant Growth (1 Gallon)
The GH pH Up comes in a robust, opaque plastic gallon jug, which is crucial for protecting the contents from light degradation. The "blue" color in the description refers to the typical coloration of the liquid (often due to the potassium hydroxide), not the bottle itself. As a concentrated solution, it feels substantial. The cap is secure, and the handle design makes pouring manageable. Pros: Highly Effective pH Increaser: At its core, GH pH Up does exactly what it's supposed to: it reliably and effectively raises the pH of your nutrient solution or water. It's a potent base (primarily potassium hydroxide, often with potassium carbonate) that gets the job done quickly. Premium Buffering for Stability: Beyond just raising pH, the "premium buffering" aspect is key. GH formulates this to help stabilize your pH, meaning it resists drifting back down quickly after adjustment. This reduces the frequency of needing to re-adjust, saving time and reducing stress on your plants. Stable pH ensures consistent nutrient availability. Reliable and Trusted Brand: General Hydroponics has been a cornerstone of the hydroponics industry for decades. Their products are well-researched, widely used, and trusted by both amateur and professional growers. This instills confidence in its quality and consistency. Nutrient-Rich Components (Potassium): Unlike some generic pH adjusters, GH pH Up typically uses potassium hydroxide as its active ingredient. This means that while you're raising pH, you're also subtly adding a beneficial macronutrient (potassium) to your plants, which plays a vital role in flowering, fruiting, and overall plant vigor. Convenient 1-Gallon Size: For medium to large-scale growers, or those with multiple systems, the 1-gallon size offers excellent value and reduces the need for frequent re-purchases of smaller bottles. It's a cost-effective option for ongoing pH management. Easy to Use (with caution): While potent, it's easy to use with standard pH testing kits or meters. Adding small, controlled amounts allows for precise adjustments. Cons: Highly Concentrated (Requires Caution): This is a very strong base. It is corrosive and requires careful handling. Always wear appropriate personal protective equipment (gloves, eye protection) and add it slowly to your solution, away from your face. Keep out of reach of children and pets. This isn't a flaw of the product, but a critical user instruction. Can Raise EC/TDS (Minor): Because it adds potassium, using significant amounts of pH Up can slightly increase the Electrical Conductivity (EC) or Total Dissolved Solids (TDS) of your nutrient solution. This is usually negligible unless you're making extreme adjustments, but it's something to be aware of if you're meticulously monitoring EC. Storage Considerations: Being a strong chemical, it requires proper storage in a cool, dark place, away from other chemicals or potential contaminants. Overall Input & Verdict: General Hydroponics pH Up Liquid is an indispensable tool for any serious grower, particularly in hydroponics where pH control is paramount. It excels in reliably increasing and stabilizing pH, which directly translates to healthier plants and optimized nutrient uptake. The added benefit of potassium and the trusted GH brand reputation make it a superior choice compared to generic alternatives. While its concentrated nature demands respectful and cautious handling, its effectiveness and buffering capabilities make it a cornerstone of successful plant cultivation. For consistent, robust growth and peace of mind in pH management, the 1-gallon size of GH pH Up is a highly recommended, long-term investment.

Rock-solid pH stability in my reservoir
I bought this to help keep my nutrient reservoir from swinging up and down after mixing, and it’s done exactly what I wanted. After adding it to my usual nutrient mix and dialing in pH, the pH has stayed noticeably steadier over the next day or two instead of drifting as much as it used to. That makes daily maintenance easier and gives me more confidence that my plants are staying in the right range. A few tips that helped: I add nutrients first, then this product, let everything circulate for a bit, and only then do my final pH adjustment. Also, a little goes a long way, so start with a small amount and work up based on your reservoir size. If you run hydro/DWC and get frequent pH drift, this is a solid add-on to your routine.

Phの調整に最適ですが、結果が出るまで時間がかかります。 添加後、最低30分ぐらいしてからPhを測らないと正確ではありません。 添加してもあまり変わらないと思って、さらに添加すると30分後大変なことになります。 1ml量れるスポイトがオススメ。

First off, what ph meter are you using? I have 3 different ones from Amazon, calibrated all in the same solutions, at 25 C, all give me different values. They’re useless. If you want to be more sure, you should also have test strips or test fluid. As for all the reviewers saying this doesn’t work, that they had to use a whole bottle or whatever to get to the ph value they were after.. I question your water source. I recently put in an RO system to use for my plants. On my old hard water (about 240ppm) it would take about 8.5ml of ph down to get my 4 gallon jug of just water (for flush) down to 6.0 from about 7.5. Now with RO water measuring 002ppm before adjust, I started on another 4 gallon jug with 3 ml, and it brought me down to 3.5. So I tried a gallon jug, I dipped my finger in the down, then into the jug. I don’t know how to add any less that that? Well, it took my 7.1 down to 4.2. INSANE. This stuff definitely works, too well. I’m new to RO, so I haven’t tried with nutes yet, but I’m hoping once I have a higher ppm in my water from the nutes that it will be less sensitive to adjust the ph. If you have water under 010 ppm and it takes more than a few drops to get your value, you should try another method of testing your ph, because your meter might be lying to you. Some other things to consider is how are you adding your down? Is the tool clean? Have you tried balancing just water? Because maybe it has something to do with the combo of nutes you’re using, or the ppm you end up at with your nutes added. See, this is the problem with online reviews. This didn’t work for someone because they unknowingly were using it wrong, then they leave a trash review. I also have the root farm ph down, and the standard hydroponics down, and it seems to work exactly the same, just as powerful. I haven’t tried the Indo brand yet, but I’m willing to bet it works just as good. So to summarize my opinion, if this isn’t adjusting your levels with just a few drops, I think you have other problems, and that this stuff works great. And to be clear, I bought this myself, I have never had any products shipped to me in exchange for a review. I am a very happy customer of all General Hydroponics products, I run their 10 part nute system in my soil grows, and notice a benefit over using the Indo nutes I started with a couple of years ago. Keep your patients, you’ll get it all figured out soon. There are a lot of areas to master in growing Mary, I’m FAR from it. Ph is an important one, some strains are more forgiving than others, but if you’re too far out your plant might (probably will) stop taking in nutes, and that’s no good.

I gave 5/5 for value for money because this stuff is so powerful that only a couple of drops (less than 1 tsp) will do the job for a gallon of water. I gave 3/5 for easy to use because it's easy to mess up and over adjust because of how concentrated it is. My advice: get yourself an eye-dropper, and make sure you have a pH meter. It was a steep learning curve, but now that I got the hang of it I love this product
