## Description

このペーハーコントロールキットは日ごろのペーハーチェックにもってこいのキットです。チェックしたい溶液を試験管の半分まで入れて、ペーハー試験薬を数滴たらして、試験管の中の液体の色を観察するだけでＯＫ。赤くなったらpHが低すぎ、青くなったら高すぎ。黄色～黄緑色が最適値です。信頼性の高い簡易ペーハーテスターです。経験豊かな園芸家たちに愛用されています。大切に育てている植物が危険にさらされるのはpHが下がりすぎた場合です。pHダウンの酸には食品グレードのリン酸（純植物栄養素）が使われています。培養液のpHが高すぎる場合に少しずつ加えていって、最適値の範囲に下げます。簡単で信頼性が高く、効果抜群です。pHアップの塩基（アルカリ）は水酸化カリウムと炭酸カリウム（ともに純植物栄養素）です。培養液のpHが低すぎる場合に少しずつ加えていって、最適値の範囲に上げます。ペーハー調整は、急速で旺盛な植物生長を保つのに欠かせない作業です。培養液のpHが高すぎたり（アルカリ性）、低すぎたり（酸性）すると、十分な養分吸収ができません。pHが適正でない培養液では、生長が遅くなり病気にかかりやすく、収穫量も減ります。

## Questions & Answers

**Q: I want the ph down only and would never need ph up. How can I buy just the single bottle of ph down?**
A: Hi, one of the easiest ways to lower water Ph, is to use vinegar, I use white Vinegar, (I am unsure if you can use apple cider vinegar).
I use the Ph test kit in the up/down kit with the chart supplied from the kit and when growing flowers, I needed the 5.5 Ph range. To start measure your water source to see what the Ph is before using anything to lower the Ph, then you have a base reference point established to know how much you will need to lower, In the up/down kit, is the supplied dropper (any dropper is okay), I use it  to draw out the vinegar and I use Iceland water the natural normal Ph in that bottle is 8.8, give or take, so then in 1.5 liters I have dropped 13 drops to reduce the Ph to 5.5 +\- .3 Ph, and that is how I do it.
Good luck.
Disclaimer: this esoteric version I am only sharing, you are on your own, heheh...

**Q: Is it common for the PH up bottle to leak all over someone’s carpet?**
A: No, it is not very common for the PH up bottle to leak all over someone's carpet but it is quite common for it to leak all over someone's laminate floor and also someone's ceramic tile floor. Vinyl floor not so much but it does happen on occasion. This is because vinyl is easier to clean so the PH up bottle has a natural tendency to not want to leak onto the vinyl. Contrary to popular belief it is also quite common for the PH up bottle to leak all over furniture. Especially antique furniture made from oak and also black walnut wood. Hope this helps.

**Q: even if i just need to lower the PH is it important to add a little of the PH up along with the PH down when lowering the PH?**
A: No you don't ever want to use ph up and ph down in the same container it's either ph up or ph down one or the other because you will mess your plants up putting both up and down in the same container. If you brought your ph down too much either add a small bit more nutrients or more water.  if you messed up and brought it to down then start over and remember what you did wrong to not do it again. Add small drops at a time cause that stuff is strong. I use it by drips. If my ph is acidic at 5 or by the color chart I Add ph up by drips like one or two then shake the container not too hard cause oxygen will cause it to go Up do when you're done softly shaking it let it sit for a bit then check the ph and add what is needed by small amounts as drops like I do it and I never go wrong cause of patience. but never add both to the same container. This is a very good product for the safety of your plants

**Q: What is the chemichal composition of the pH up and pH down?**
A: sorry, i can't help you with the chemical composition. I live on the West Coast near Washington and the water here is almost perfect at 5.5 or 6. You will need very little ( a few drops ) to drive the ph up or down. This product does work. Google " How to change your water's ph " and you will get lots of advice. If your ph is too high or low your plant nutrient food will sediment out and be impossible to be utilized by the plant. I suggest that you get proper hydroponic plant food. I no longer use this product but first step is to find out what your waters ph is.This will help. Good luck.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Its serves it purpose
*by  on Reviewed in Japan November 4, 2025*

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

### ⭐⭐⭐⭐⭐ 良い
*by  on Reviewed in Japan November 11, 2025*

素晴らしい。

### ⭐⭐⭐ bottle labels are not colorfast
*by  on Reviewed in Japan May 21, 2022*

Though the product works fine, if the bottle labels get wet the ink comes off and makes a mess. This is a significant problem since the pH color chart is on bottle, and your hands will surely get wet when testing pH. I had to wrap the bottles in clear packing tape.
