Description

pH Buffer Solution 7.0 is an essential calibration solution for ensuring your pH meter or pH pen reads accurately at the neutral pH 7 reference point. Regular calibration with a pH buffer solution is critical for hydroponic and soil growers alike — inaccurate pH readings lead to nutrient lockout, deficiencies, and stunted growth, making this a non-negotiable part of any serious grower’s toolkit.

This buffer solution provides a stable, certified pH 7.0 reference point, allowing you to verify and adjust your pH meter with confidence. For best results, calibrate your meter using both pH 4.0 and pH 7.0 buffer solutions at each use.
