Garden Genie pH Up Down Solution for Hydroponic Systems, 250ml Each

The product is worthy to give 5-star rating. This ph control kit from Garden Genie is a reliable solution for maintaining balanced nutrient levels in your hydroponic system. I use this test kit to test the ph of the nutrient mix. Then you have the ph up and ph down to adjust as needed. Very easy to use and includes everything you need as well as detailed instructions. This is a great set and good size bottles at a very affordable price!! Since you only use a few drops each time this should last a long time. I highly recommend this kit for anyone looking to optimize their hydroponic growth.

Good

Product is good is working properly but price was so high. If you need pH down just only use phosphoric acid for grade available in local market 120 rupees per litre

This product does exactly what it says it does! efficiently too! I tested this on my hydroponic system with a calibrated pH meter. 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. 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. 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 needing more solution and spending more money. 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 overdo it, always undershoot what you are aiming for; you will save product and also prevent too acid/basic solution.

Ph down is very diluted , i have to mix whole 100 ml in just 30 liter water to bring ph from 7.0 to 6.0 and it got bumped up to 6.7 after 2 days. i will not recommand it.

Quality product

I would definitely say this is a good buy. And I would recommend it to anyone. I have used this exact same pH kit for years and have never been disappointed. You basically just have to eye it and it's kind of trial and error from there but once you have used it a few times you begin to get a feel for how much to use depending on the water/soil as well as how much is too much or too little to balance your ph.

Product and packaging came sealed and untampered. Great! However, the concentration is quite low. 1ml per liter to drop the ph level from 6.8 to 5.7. And the PH level does not stay long. Its only stable of 1 week. then it goes back to 6.8 again. i can only recommend this for quick fix. not for lasting use.
