Bluelab pH Pen

SKU: BLPHP

pH is crucial to the health of your hydroponic system. Plants need nutrients and minerals to grow, but they can only absorb them in the right pH range.

If your plant’s leaves turn yellow and droop it’s usually not because there isn’t enough nutrients, but rather that they can’t absorb the available nutrients due to high pH. Also, some common minerals like manganese and aluminium become toxic at low pH. And the beneficial microorganisms that your plants need to flourish can only thrive at a neutral pH. You need to test your pH for maximum growth and yield.

The Bluelab pH pen is compact, handy and quick. It not only measures pH, it also takes the temperature (and automatically compensates for it) so you can tell if your plants are too hot or too cold. It’s fully waterproof so no worries if you drop it in your nutrient solution, it’s a snap to calibrate, and automatically shuts off to save battery power—and batteries are included! Comes with a one-year manufacturer’s warranty.

Pro tip: Looking to test soil pH? Grab a Digital Soil pH Meter.
