**Green Air pH Raise – Standard Strength pH Up Solution**
Green Air pH Raise Standard Strength is an **easy-to-use pH buffer formulated to increase the pH of nutrient solutions when they become too acidic**. It gives growers a practical way to stabilize nutrient-solution pH and maintain conditions that support proper nutrient availability and plant uptake.
Maintaining the correct pH is an important part of a successful feeding program. When pH becomes too high or too low, certain nutrient elements can become less available for plant absorption. Green Air states that the optimum nutrient-solution pH range for cannabis is approximately **5.5–6.5**.
