To maximize plant growth, the pH content of your nutrients should be slightly acidic.
For maximum plant growth and health, it is recommended to adjust the pH of your water or mixed nutrients for most plants between 5.5 and 6.5. This pH Down Hard Water solution is 3x more concentrated than our standard pH Down formula. We know growers with hard water, or with larger reservoirs, require a stronger pH down than those with soft water or using purified water sources. This higher strength product will help you reduce consumption and save money when pH balancing your solutions.
Using Indo pH UP and DOWN helps the grower moderate and maintain optimum pH levels. The pH scale is a measure that describes the relative acidity or alkalinity of a solution or medium. Both pH-balancing aids are manufactured using the highest-quality ingredients: potassium hydroxide to raise pH, and phosphoric acid to lower the pH levels.
