**Green Air pH Lower Max – Commercial Strength pH Down Solution**
Green Air pH Lower Max is a **maximum-strength pH lowering solution formulated for commercial growing applications**. It is designed to reduce the pH of nutrient solutions when they become too alkaline, helping growers maintain the proper conditions for nutrient availability and efficient plant uptake.
Maintaining the correct pH is an important part of nutrient management. When a nutrient solution becomes excessively acidic or alkaline, certain essential elements can become unavailable to plants. Green Air states that the optimum nutrient-solution pH range for cannabis is approximately **5.5–6.5**.
