Nutrient solution pH that is too high (basic), or too low (acidic), cannot be properly absorbed by plant roots. Incorrect nutrient solution pH can cause slow growth, sickly plants, and low yields. But General Hydroponics® pH Control Kit is here to help. The kit contains everything you need to test pH levels and make adjustments so you can easily monitor and manage pH levels throughout your hydroponic grow. Kit includes: 8 oz. pH Up, 8 oz. pH Down, 1 oz. test indicator, a test tube, eyedropper, and pH Level Chart. To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5. 5 and 6. 5.

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 ### ⭐⭐⭐⭐⭐ Honest Review *by S***I on 17 December 2021* After using this PH Up&Down for a while now I can tell you this all what you need...easy to use and very fast to change the PH status in your water....
