pH Control

Why is pH control important?

pH control is an important part of preparing nutrient solutions for hydroponic, coco and soil growing. Measuring and adjusting pH helps growers maintain consistent growing conditions and follow the feeding recommendations provided by nutrient manufacturers.

Regular testing and adjustment are especially important when mixing fresh nutrient solutions or changing water sources.
