Growth Technology pH Buffer 4 300ml

🌱 Growth Technology pH Buffer 4 300ml — Guide and Product Information

Product Overview

Growth Technology pH Buffer 4 300ml is a calibration solution with a known and fixed pH value, used to calibrate pH meters and help maintain ongoing accuracy. Regular calibration is an important part of pH management for growers using hydroponic systems, coco, soil, reservoirs and hand-mixed feed solutions.

Accurate pH measurement plays a key role in nutrient availability and day-to-day crop management. Using a reliable buffer solution helps confirm that your meter is reading correctly before you make adjustments to your water or nutrient mix.

Main Use and Benefits

This product is designed for calibrating pH meters at pH 4. By checking your meter on a regular basis, you can reduce the risk of inaccurate readings that may lead to over-correction or under-correction of your nutrient solution.

• ✔ Provides a known fixed pH reference for calibration
• ✔ Supports more dependable pH meter performance over time
• ✔ Helps improve confidence when testing nutrient solutions and water supplies
• ✔ Well suited to routine grow room maintenance

Features and Practical Use

As a fixed-value pH buffer, this solution is intended for calibration rather than nutrient adjustment. It is best used according to the instructions supplied with your pH meter, with fresh solution poured into a clean container for each calibration check where possible.

Suitable Applications

Growth Technology pH Buffer 4 is suitable for growers and horticultural users who rely on pH meters to monitor feed water, nutrient reservoirs and irrigation solutions. It can be used in hydroponic growing, coco systems, soil-based cultivation, propagation areas and general indoor horticulture.

It is particularly useful wherever accurate pH readings matter for nutrient uptake and feeding consistency. Growers using products such as PLAGRON TERRA GROW 10L or PLAGRON TERRA BLOOM may benefit from routine meter calibration as part of their regular feeding schedule.

FAQ

What is Growth Technology pH Buffer 4 used for?
This solution is used to calibrate pH meters so they continue to provide accurate readings when testing water and nutrient solutions.

Why should I calibrate my pH meter regularly?
Regular calibration helps maintain accuracy over time. This is important when managing feed strength and pH, as inaccurate readings can lead to incorrect adjustments.

Is this product used to lower the pH of my nutrient solution?
No. This is a calibration buffer, not a pH down product. It is designed to check and calibrate the meter rather than adjust the pH of your feed or reservoir.

Where can I use this pH buffer?
It is suitable for hydroponics, soil growing, coco systems, propagation and general horticultural use wherever a pH meter is used.

What size is this bottle?
This product is supplied in a 300ml bottle, which is a practical size for regular calibration and grow room maintenance.

How should I handle the solution during calibration?
Pour out only what you need into a clean container and follow your meter instructions carefully. This helps keep the remaining solution clean and suitable for future calibration checks.
