General Hydroponics pH Up Liquid is premium solution maintaining and raise a nutrient's pH level. 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. To 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 for hydroponic gardens and 6.0 to 7.0 for soil applications.

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.

Grower’s Tip: When adjusting pH, start out with one ml per gallon. Wait 15-30 minutes, and test your water again. Frequently you will only need 1-2 ml per gallon of water. You may need to use more if you have hard water.
