Measuring soil pH and temperature

The fundamentals of growing

All plants need a balanced diet of nutrients (food) in order to grow. However, plants can only access nutrients if the pH (potential Hydrogen) of your growing medium falls within the correct range.

Contrary to popular belief, all growers need to measure pH, regardless of whether you’re growing in soil or in solution. That’s because pH plays an important role in making your nutrients soluble so that they can be absorbed by plants. If your medium is too alkaline or too acidic, your plants won’t be able to get all the nutrients they need. Temperature is also important, as it can impact your plants’ structure and growth rate.



A robust and versatile handheld solution

Accurate measurements, every time

This hardy soil pH pen measures in increments of 0.1 pH and is fully temperature compensated, so you can rely on getting accurate readings every single time. In addition, this versatile pen can be used in a variety of growing media, including soil, coco coir, potting mixes and solutions.

Made in New Zealand, built for growers

Created in New Zealand, our entire product range has been designed for the grower environment - not the lab. So, you can feel confident that your Bluelab Soil pH Pen will withstand the knocks, drops and deep-water plunges that come with everyday growing.



Team up with the Bluelab Pulse Meter

Create your complete root zone toolkit

Along with measuring soil pH, you’ll need to check that you aren’t over- or under-feeding your plants.

After all, nutrients can be expensive so it’s important that you always optimise them. Conductivity (EC or PPM) is a fundamental measurement that will help you ensure that your plants are always getting the right amount of food.

The Bluelab Pulse Meter will allow you take quick and accurate measurements of the conductivity, moisture and temperature of your root zone.

When you combine the Bluelab Soil pH Pen and Bluelab Pulse Meter, you’ll be creating the ultimate root zone toolkit, ensuring that your plants can truly thrive.
