General Hydroponics GH pH Down ペーハーダウン 946ml

good

少しで、めちゃくちゃ下がりますよ。気をつけて使用して下さい。

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。

ph調整剤です。 愛用品です。

I have a simple hydroponic tower with a 5 gallon water capacity and this pH down works excellently. It doesn’t take much to lower the pH at all, the insurrections for adding are clear and the results speak for themselves.

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.

Useful for hydroponic gardening. I was happy with the results

It's pH down to use with hydroponics / growing so nothing crazy to write about. Use as needed whenever your water is above the ideal range. I bought mine in 2021 and have had some inconsistent results with it recently where a small amount brought the pH down more than it usually would. That's happened three times now so I took some time to shake it and hopefully that resolves the inconsistencies. If I can't figure that out then I'll replace it since I don't like not being able to estimate how much to use for a certain pH and volume of water. MSDS sheet from 2021 I found indicates its 10-17% phosphoric acid. Therefore I put value for money pretty low since you can buy food grade phosphoric acid at 85% for pretty affordable prices and dilute it yourself. If your churning through this stuff and want a more affordable option I would suggest you look into that.

Strong acid, don’t get it on you. I use 6ml for a 5 gallon jug of nutrient water to reduce PH from a 7- 6. Works well
