General Hydroponics pH Control Kit
The pH Control Kit includes one liquid pH test kit and 8 oz of each Up (base) and Down (acid). The pH Test Kit is a liquid tester that covers a pH range of 4.0 to 8.5. Includes sampling tube, reagent and color comparison card. Both pH Down and pH Up provide consistent and reliable performance.
General Hydroponics PH Up & Down helps maximize plant growth, the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media – such as rock wool and gravel products – are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.
pH Down: Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.
pH Up: Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.
