Description

pH control is essential for stimulating vigorous plant growth. Nutrient solution pH that is too high(basic), or too low(acidic), can not be properly absorbed by plants. The pH scale measures acidity or alkalinity on a scale of 0 to 14. Below 7.0, the pH is acidic, above 7.0, the pH is alkali(basic), 7.0 is “neutral”. The best pH for plant growth is generally in the range of 5.5 to 6.5 -- slightly acidic. pH down can lowers nutrient solution pH, pH up can raise nutrient solution pH. TIP: After opened the PH down solution, the container solution will appear black precipitate, that is a condensate after the acidic substance is sealed, and this condensate does not affect the effect of use, please feel free to use it. Our pH up and down control Kit is safe to use for all indoor & outdoor plants, flowers, vegetables & herb gardens , organic lawn & turf care, fruiting & non- frunting trees, crops Optimal nutrition ingredients formula help promote strong, green foliage and a thriving root system. Appropriate for most houseplants. Our updated odorless and colorless hydroponics pH up and down kit is suitable for hydroponics systems, soilless mediums, soil gardens.

    • So easy to use and balance the ph more accuratly than just strips!
This is so easy to use and balance the ph in my fish tank. House water tends to be to high alkalinity so adding even soft water does not change this. This test is just a little tube of water and a drop of testing solution....more accurate than test strips. A must have for keeping fish and plants happy. ... show more

    • A must-have for well water! Keeps my houseplants thriving.

My husband originally bought this kit about a month ago to help us regulate the pH of the water for our houseplants. We are on well water here, and the levels can be pretty unpredictable, so having a reliable way to stabilize it has been great. We’ve been using it consistently, and so far, it’s been working exactly as it should to keep the water at an adequate level for the plants to stay healthy. The chemical content is effective but easy to manage—a few drops of the "Up" or "Down" solution and we're good to go. In terms of use and ease of use, the included dropper makes it very simple to get a precise measurement without any mess. I was specifically worried about leakage, but the bottles are sturdy, and the caps seal tightly, so we haven't had a single drip or spill in the cabinet. For the price, the value for money is excellent because the solutions are concentrated; this kit is going to last us a very long time. The durability of the packaging feels high-quality, and it’s a relief to have a consistent solution for our well water issues. Definitely worth it if you want to stop guessing about your water quality! ... show more

    • Works well, just not the strongest solution
I picked this pH control kit up to help manage water levels for my plants, and overall it’s been pretty useful once you get the hang of it. The adjustability is solid. You can dial things in pretty precisely by adding small amounts at a time, which makes it easier to avoid overcorrecting. I was able to get my water into a better range without too much guesswork after a couple tries. The ease of use is good. The testing process is simple, and once you understand how the drops affect your water, it becomes pretty straightforward. It’s not complicated, just takes a little patience at first. The effect on water content is noticeable, but it’s not super strong. You may need to use more solution than expected, especially if your starting pH is far off, which can go through the bottles a bit faster. The durability of the bottles is decent. They feel sturdy enough and seal well, though I did notice one cap needed to be tightened carefully to avoid any small drips. I didn’t have any major leakage issues, but I can see how it could happen if the caps aren’t fully secured. It’s something to keep an eye on when storing them. It works across different setups, which is nice. I used it for basic plant watering, but it would also work for hydro setups or other uses. The included testing solution is helpful for getting a quick read, though it’s more of a basic indicator than something super precise. For the price, the value for money is decent, especially as a starter kit, but if you need something stronger, you might go through it quicker than expected. Overall, this is a good entry-level option for managing pH levels, just be prepared to use a bit more solution to get the results you want. ... show more

    • Waste of money
Does nothing for lowering Ph . Very poor instructions. And not for testing soil .

    • Works as advertised, but not as strong as General Hydroponics.
I’m reading this at three out of five stars not because it didn’t work, but because it required a lot more solution to balance my tapwater compared to other brands. I almost had to use twice as much of this pH up compared to the general hydroponics, but can’t attest to the pH down as I never needed to use it. The indicator solution worked well, the solution actually worked and adjusted my water, I just burned through the bottle way faster than I should have. Going forward I’ll stick with general hydroponics but this would work in a pinch! ... show more
