If your pH probe dries out, your readings drift, your feeds go wrong, and your plants feel it. This pH probe storage solution is the simplest way to keep your readings accurate and your grow dialled in. The Growth Technology pH Probe Refill & Storage Solution (300ml) is a potassium chloride (KCl) solution designed specifically to keep pH electrodes hydrated, stable, and performing properly. No guesswork, no drift, no replacing probes early. Summary: Keeps your pH probe accurate, extends lifespan, and stops dodgy readings before they start. Why You Actually Need pH Probe Storage Solution pH probes rely on a hydrated glass membrane to measure correctly. Let it dry out and accuracy drops off fast. Storing your probe in proper KCl pH storage solution keeps the electrode conditioned so you get consistent readings every time. Maintains accurate pH readings – no drift, no guesswork Extends probe lifespan – saves you replacing pens early Prevents probe damage caused by dry storage Essential for hydroponics, coco, and soil growing Key Features Designed for pH meter probe storage and maintenance Suitable for refilling liquid-filled pH probes Made with potassium chloride (KCl) – the correct storage medium Compatible with most pH pens and meters Easy to use, no mixing required How to Use Simple: Add a small amount of solution to your probe cap Store the probe with the tip slightly submerged Top up refillable probes if required Replace solution regularly for best results That’s it. Keep it wet, keep it accurate. Common Mistakes to Avoid ❌ Letting your pH probe dry out ❌ Storing in plain water (kills accuracy over time) ❌ Ignoring drifting readings until it’s too late Product Specifications Product Type pH Probe Storage & Refill Solution Volume 300ml Active Ingredient Potassium Chloride (KCl) Compatibility Most liquid-filled pH probes and meters Who It’s For Hydroponic growers running daily feeds Coco growers needing tight pH control Soil growers who want consistent results Anyone using a pH pen or pH meter Straight Talking This is one of the cheapest bits of kit in your setup, but one of the most important. If you’re not using pH probe storage solution, you’re shortening your probe’s life and risking inaccurate feeds every single day. Sort your storage, and your pH readings sort themselves.
