General Hydroponics pH Up Premium Buffering for pH Stability Achieve perfect pH 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. 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. pH can acidify to an unacceptable level when nutrient solutions are used with poor-quality water, or pH-unstable media, such as rockwool. High growth rates can also destabilize pH. Base solution is formulated using potassium hydroxide and potassium carbonate Add when your nutrient pH is too low in order to raise the pH to the proper level Promotes pH stability How to Use: Use sparingly – add to nutrient solution, a little a time, then test pH. Repeat application, then test, until desired pH is achieved. The quantity necessary for pH adjustment will vary depending on the strength of the nutrient and the purity of the water used to mix nutrient.
