If you have grown before, you understand how fickle plants can be sometimes. They'll only thrive under very specific conditions. One of the most important aspects of your grow you need to monitor is the pH and temperature of the nutrients you feed them. If these are out of whack, it will lead to issues with uptake.
Plants can only take up nutrients when pH is in a specific range between 5.5-6.5. Any lower or higher, and certain nutrients get locked out, presenting the possibility for deficiencies. A good way to look at it is the nutrients you feed your plant are a lock, and proper pH is the key!
The Bluelab pH Pen also measures the temperature of your solution, ensuring you don't feed a solution that is too hot or cold. This can also affect nutrient uptake, but also can contribute to issues such as mold or mildew in the root zone. When paired with the Bluelab ppm / EC Pen , you'll have access to all the metrics you need for ensuring your plants are thriving, and reach their full potential!

I am unable to successfully calibrate my pH pen
What if my pH Pen or pH Probe has accidentally dried out?
The pH pen or probe must be 'hydrated' for 24 hours. Place the pH probe or pH pen upright in a small plastic container. Add enough KCl storage solution into the container to cover the pH probe tip. Leave the pH pen or pH probe to soak in the KCl solution for at least 24 hours.
Carry out a calibration to check if the pH pen or pH probe has already suffered permanent damage.
What is KCl storage solution?
KCl storage solution is generally a mixture of Potassium Chloride (KCl) and water. Some brands may contain small amounts of other ingredients.
