Hydroponic Nutrients - General Hydroponics pH Test Kit, 8oz Wide Spectrum Liquid Indicator for Accurate Readings

Relying on cheap paper strips or constantly drifting digital meters can easily lead to devastating nutrient lockouts in your expensive indoor garden. This General Hydroponics pH Test Kit acts as a highly dependable hydroponic nutrients indicator, delivering instant, visually accurate readings that never require frustrating technical calibration. You can easily trust this foolproof method to keep your demanding crops exactly within their optimal absorption range.

Formulated with a highly sensitive, wide-spectrum chemical reagent, this specialized liquid turns different vibrant colors based precisely on the acidity or alkalinity of your water sample. When you pull a small amount of your mixed hydroponic nutrient solution into the provided test tube and add a few drops of this liquid, it will immediately display a distinct color ranging from deep red (highly acidic) to dark blue (highly alkaline). The goal is to hit the golden yellow-green color that represents a perfect 5.5 to 6.5 range. Because this liquid fertilizer indicator utilizes basic chemistry rather than delicate electronic sensors, it provides incredibly consistent results that you can physically see and verify with your own eyes every single time you mix a fresh tank.

Use this large 8oz refill bottle to conduct daily or weekly spot checks on your deep water culture buckets, automated drip reservoirs, or hand-watered runoff. It is an absolute essential tool for any serious grower managing a highly demanding soilless potting mix or pure coconut coir setup where pH fluctuations occur rapidly. You simply compare your final colored tube against the included, easy-to-read waterproof chart. This premium testing solution from General Hydroponics delivers the absolute peace of mind required for running a flawless, heavy-yielding garden.

Store in a cool, dry place away from direct sunlight and moisture. Reseal packaging tightly after use to maintain product quality and effectiveness.
