X Nutrients – PH Down

41jupwhj86l._sl500_ss500

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. Available in 1 Quart 1 Gallon 2.5 Gallons 5 Gallons 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. 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 the
