The Flairform pH Test Kit is a liquid indicator for testing nutrient pH in hydro, coco and soil — no batteries, no calibration, no probe maintenance. One to two drops per test gives a fast, reliable reading across pH 4.5 to 9.0, matched against the waterproof colour chart printed on the bottle. One 30ml bottle delivers up to 800 tests, and a sturdy test tube is included. It's the simplest way to check pH, and the smartest back-up for cross-checking an electronic meter.
Specifications
- Compare the tube against the chart in natural or white light — coloured grow room light (especially HPS or blurple LED) will throw the colour match right off. Step outside the tent.
- Rinse the test tube with clean water after every test. Nutrient residue in the tube skews the next reading.
- Keep the bottle capped with the dropper nipple in place and store it cool and dark, away from ignition sources — the indicator is alcohol-based.

Frequently Asked Questions
How accurate is a liquid pH test kit compared to a meter?
Very reliable — a drop kit gives accurate colour-matched results every time with nothing to drift. Even properly maintained electronic meters can read wrong, because lower-quality electrodes respond to foreign species like sodium. That's why many growers cross-check their meter against a test kit.
Does it need calibration or special storage?
No. There's no calibration, no buffers and no probe care — just keep the bottle capped and stored cool and dark. That's the whole appeal over an electronic meter.
How many tests do I get from one bottle?
Up to 800 tests from the 30ml bottle at 1–2 drops per test. Checking a reservoir daily, one bottle covers well over a year of grows.
Can I use it for soil and coco as well as hydro?
Yes. It tests the pH of any nutrient solution or feed water across hydro, coco and soil. For testing soil itself, Flairform makes a dedicated Soil pH Test Kit with a conditioner for soil samples.
Is it safe to handle and ship?
Yes. It's classified as non-hazardous and a non-dangerous good. The indicator is alcohol-based, so the 30ml dropper bottle uses a flow-restricting nipple, and it should be stored away from ignition sources. Keep it out of reach of children.
