Bluelab Soil pH Pen

The pH level of soils, substrates, or media strongly influences crop performance. Most soils have a natural buffer for nutrients and pH, but when it goes wrong, it goes really wrong and fast.

Yellow leaves, stunted growth, slow growth, are all signs that the plant is not getting the nutrients they need from the soil. This is often caused by ‘lock up’. This is a situation where the plant loses the ability to absorb specific nutrient elements because the pH value of the soil is incorrect. Do you know what the pH of your soil is? 

This needs to be dealt with quickly, so the Bluelab Soil pH Pen is exactly what you need. This handheld pen comes with a replaceable Soil pH Probe and instructions for measuring direct into soils or measuring a soil solution.

Used for cropping, pasture, turf culture, containerized plants, home gardens, orchards, tree farms, greenhouses, propagation culture… anywhere that involves growing plants in soils. The replaceable soil pH probe can be used to measure the pH value of solutions or nutrient mixes too!
