pH is the measurement of water quality. Soil or water can be too acidic or too alkaline. A pH of 7 is neutral. In general plants respond best to a pH between 5.5 and 6.5 for maximum nutrient absorbency. pH-Up and pH-Down adjust the acid/alkaline balance of your water. pH that is either too high or low will prevent plants from absorbing nutrients. To make the most out of your nutrients use pH-Up and pH-Down to regulate your pH.

A pH meter or strips can be used to measure the pH of water, nutrient solution and soil.
One of the most overlooked aspects in effective gardening is pH. Without the proper pH balance, plants will not efficiently uptake nutrients. pH is measured on a scale of 1-14, 7 being neutral, less than 7 being acidic and above 7 considered a base. Here are some examples; pure water has a pH of 7, bleach has a pH of 13 and lemon juice has a pH of 2.
Technical: pH has to do with the number of hydrogen ions. In water (H2O), there are a small number of molecules that dissociate or split up. These molecules loose a hydrogen ion and become hydroxyl ions (OH-). The lost hydrogen ion joins with other molecules to become hydronium ions (H3O+). In pure water, there is an equal number of hydrogen ions and hydroxyl ions which makes a pH of 7. In an acid, which has a pH of less than 7, there are more hydrogen ions. In a base, the opposite is true. The pH scale is logarithmic, which means that for each value change in pH there is a tenfold change in the number of hydrogen/hydroxyl ions. In other words a solution with a pH of 6.0 is ten times more acidic than a solution with a value of 7.0.
When pH is not at the proper levels, a plant will lose its ability to absorb the essential elements required for healthy growth. This is why pH is so important. With X Nutrients pH Up and pH Down, you can easily adjust the pH to produce optimum growth results. Generally most plants prefer a slightly acidic environment, ranging from 5.8 - 6.5. When pH starts rising above 6.5, some of the nutrients will precipitate, or fall out of the solution, and stick to the walls of the reservoir. For example, iron will fall out of solution completely at a pH of 8.0. So if you are using a solution with a pH of 8.0, your plants will never get iron regardless of how much you use. Left uncorrected, this will result in an iron deficiency, slow growth, and eventually death. Below is a chart that shows some various elements and the effect pH has on absorption. You will notice that the greatest absorption of nutrients occurs from 5.8 - 6.5. Proper pH is especially important in hydroponic environments due to the fact that the plants are sitting in the same water for a long period of time. Alternative mediums such as various soils, coco, and rockwool, offer pH buffering making it more forgiving and offering a higher rate of success where pH is not constantly being monitored. Nonetheless, pH needs to be adjusted to ensure proper nutrient uptake.
Checking pH in a nutrient solution is very easy. There are paper test strips, which are the most inexpensive way to check pH. These strips contain a dye that changes color according to pH. The most technical way to measure pH is a digital meter. There are various types available on the market with a wide range of prices depending on their accuracy and other features. Digital pH meters should be calibrated often as they tend to drift over time. Most pH meters should never be allowed to dry out and should be stored using a storage or buffer solution.
X Nutrients pH Up and pH Down make it easy to adjust pH. Simply use the recommended dosage found on the label to increase or decrease pH. Make sure you are constantly monitoring the pH as you add more. What makes X Nutrients pH Up and pH Down a good product to work with is that we use a mid range concentration that makes it easy to dial in your ph to the perfect level. Higher concentration pH products are available on the market; however these products, due to their strength, tend to cost more and are difficult to work with. The higher concentration means that a little amount makes a huge difference in pH, and as a result your pH swings back and forth as you try to adjust it. X Nutrients pH is available in quarts, gallons, 2.5gal, 5gal, and 15 and 55 gallon drums.
General Usage:
Hydroponics - Use 1 mL per gallon in your reservoir as a starting point. Make sure the product is dissolved and mixed thoroughly (or cycled). Measure pH to determine additional amounts.
Soil/Coco/Other medium - Use 1 mL per gallon in your water source as a starting point. Make sure the product is evenly distributed. Measure pH to determine additional amounts.
Note: Never premix with another product, always add directly to the reservoir. Adjust your pH after adding all your products.
All X Nutrients products are not available for sale in Oregon.
XNutrients ph Down is now concentrated to 30% three times the amount of our original formula! As with all products we formulate our goal is to provide our customers with the best products possible at affordable prices. A little bit of the new ph Down concentrate will go a long way please add small doses at a time and re-test your ph levels until the desired ph is reached.

What is pH Up?
pH is a measure of acidity or alkalinity.
For growing in soil, the pH range should be 6.0 to 6.5.
In hydroponics, pH should be maintained between 5.5 and 6.0
When the proper pH is achieved, the nutrients become more available to the plant. pH levels that are too low or too high can result in the release of, or tying up of minerals in soils that can lead to toxic or deficient levels of some mineral elements. If pH is too high, lower the pH using Dyna-Gro pH-DOWN.
pH of 7.0 is considered neutral.
A lower pH is considered acidic and a higher pH is considered alkaline.
Application Rates
Before adding the nutrient solution: Using a pH meter to measure the acidity or alkalinity of the water. If the pH is LOWER than 6.0 (5.5 for hydroponics), add pH DOWN to nutrient solution in ½ tsp. per gallon increments until desired pH is achieved.

Formulated with Phosphoric Acid.
Use Chemboys Citric Acid to help treat soil alkalinity. If your soil has high alkalinity for a particular plant, citric acid can be mixed in with the soil to help raise the soil's pH. In low doses, Chemboys Citric Acid can be a beneficial repellent of certain organisms and pests.Citric Acid lies below 4.0 on the pH scale, meaning that it is acidic and potentially corrosive. The optimal pH for plant growth is between 5.5 and 7.5
General Hydroponics Pro pH adjusters are based on completely different technology than our traditional smaller sized adjusters offering.
