Essential pH Management.

Let’s get one thing straight: pH isn’t optional. Plants need a specific range — typically between 5.5 and 6.5 in hydroponics — to take up nutrients. If the pH drifts too low (acidic), nutrients get flushed straight through your medium, never reaching the roots. If it’s too high (alkaline), nutrients bind up, becoming insoluble. That means yellowing leaves, stunted growth, and a crop that looks more like a botany lesson in failure than food.

The Aqualine pH Stick helps you dodge all that. It measures from pH 2 to 10, so whether you’re growing in soil, coco, peat, or full-on hydro, this stick gives you what you need to keep your feed solution in the Goldilocks zone.

Works Like Magic.

You don’t need a PhD to use this thing. Just dunk the bottom end of the Aqualine pH Stick into your slightly damp growing medium or nutrient solution (right up to the dotted line), wait a few seconds, and the result will light up directly on the stick. That’s it. No calibration needed. No menus. No Bluetooth. No app. Just the number you need, when you need it.

Oh, and when you’re done? Wipe it clean, keep it dry, and chuck it in your bag or pocket. It’s got a built-in carry strap and is small and lightweight enough to forget about until you need it again.

Rugged. Ready. Waterproof. 

You know what doesn’t survive long in a grow room? Fragile electronics. The Aqualine pH Stick is water-resistant, meaning it shrugs off splashes, spills, and damp environments with ease. It’s built for greenhouses, grow tents, outdoor plots, and even your kitchen windowsill if that’s your thing.

Use it in soil, coco coir, peat-based mixes, or hydroponic reservoirs — it doesn’t care. Just make sure your sample is moist or mixed with water, and the stick will take care of the rest.

Simple. Trustworthy. Aqualine.

Simple: it works. Unlike clunky digital meters that need recalibration every other Tuesday, or cheapo chemical kits that belong in a high school chemistry lab, the Aqualine pH Stick gives you quick, reliable results with none of the faff.

And here's the best bit: it's affordable. You don’t need to remortgage the shed to monitor your soil conditions. Whether you're just starting out or you're managing a climate-controlled grow space with automated feeding systems, this tool fits in your hand and your budget.

Perfect PH Everytime.

The Aqualine pH Stick isn’t glamorous. It won’t sync with your phone or play a jingle when you get a perfect reading. But it will tell you — quickly and accurately — whether your grow is heading toward success or disaster. And for something this portable, durable, and precise, that’s more than enough.

Get one. Use it. Trust it. Because when it comes to pH, ignorance isn’t bliss — it’s just slow death in a plant pot.
