HY-GEN pH 4 Buffer Solution | 250ml, 1L, 5L | pH Calibration Solution

🧪 HY-GEN pH 4 Buffer Solution, The Essential Lower Calibration Point

Accurate pH readings start with proper calibration, and proper calibration starts with pH 4. HY-GEN pH 4 Buffer Solution is the critical lower calibration point for two-point pH meter calibration, ensuring your meter reads accurately at the lower end of the pH range where your nutrient solution operates. Formulated using high quality analytical grade ingredients and supervised by a chemist with over 25 years of experience, every batch delivers the precision and consistency your grow depends on.

📐 Why the Lower Calibration Point Matters

The optimal pH range for nutrient solutions sits between 5.8 and 6.5, with 6.3 being the sweet spot for most plants. Stray outside this range and key nutrients become unavailable, no matter how good your feed program is. Two-point calibration using both pH 4 and pH 7 buffer solutions ensures your meter is accurate across the full range, especially at the critical lower end where most growers operate.

🔬 Two-Point Calibration Made Simple

When using electronic pH meters, a two-point calibration is strongly recommended for reliable results. pH 4 Buffer Solution serves as the lower calibration point, paired with HY-GEN pH 7 Buffer Solution as the upper point. Together, they give you a fully calibrated meter you can trust for every pH check, every feed, every day.

⚗️ Analytical Grade Quality, Every Batch

HY-GEN guarantees the quality of all calibration and care solutions. Each formulation is produced under strict supervision to ensure accuracy, repeatability and long shelf life. Whether you are a home grower calibrating once a week or a commercial operation calibrating daily, HY-GEN pH 4 Buffer Solution delivers consistent, reliable results every time.

📦 Available in 3 Sizes: 250ml, 1L and 5L

Choose the size that suits your calibration routine. The 250ml is ideal for home growers and small systems, the 1L suits regular use in medium grows, and the 5L is built for commercial operations or high-frequency calibration schedules.
