In addition, this versatile pen can be used in a variety of growing media, including soil, coco coir, potting mixes and solutions. With temperature compensation, it provides highly accurate readings, as well as displaying the temperature of your nutrient solution onscreen.

Combine it with the Bluelab EC Truncheon to create the ultimate Grower’s Toolbox and achieve optimal plant health.That’s why you need to regularly measure pH; if your medium is too alkaline or too acidic, your plant won’t be able to access all the nutrients they need. The pen also features automatic temperature compensation and auto-off function, making it a convenient and user-friendly option for plant care.

Use the pH pen to quickly and accurately know if your solution is too acidic or alkaline, or too hot or cold. From a water chemistry perspective, pH (potential Hydrogen) plays a pivotal role in making the nutrients in your solution soluble so that they can be accessed by your plants. This product brings you the power to accurately monitor pH and temperature, allowing you to make data-driven decisions for optimal plant health and growth. All our pH care products include clear instructions, so you can take care of pH meter maintenance with ease.

After you clean your pH probe with our pH care kit, you’ll calibrate your meter with pH calibration solution, at two reference standards - 4. Its design lets it float if accidentally dropped into your reservoir, ensuring it stays accessible and safe. Along with measuring soil pH, you’ll need to check that you aren’t over- or under-feeding your plants. 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.

If the probe does dry out it must be soaked for 24 hours in the same way it is before first use (see above).This Grow Room Essentials collection will help you organise your growing space to ensure everything is working at its maximum potential.

But what about all the smaller necessities that are so important such as pH testing kits, trays and clamps?Created in New Zealand, our entire product range has been designed for the grower environment - not the lab. It can quickly and accurately measure the pH and temperature of your nutrient solution so you can always get the very best results from your crops. With a backlit LCD display, double junction probe, hold function, low battery warning, and waterproof design, the pH pen offers accurate readings. Included Battery: The pH Pen has one AAA battery, allowing you to power it on and start measuring immediately. The easy-to-follow calibration process will ensure that your pH measurements remain accurate; if you’re using your pH meter every day, it will need to be calibrated more regularly.
