The ultimate handy solution for measuring pH and temperature!
Plants get their nutrient from minerals but they can only get all the right minerals they need if certain conditions are right. Think of nutrients like a lock. pH is the key. A key factor that affects food uptake is whether your solution is acid or alkaline. We measure this in pH.
The Bluelab pH Pen also measures the temperature of the solution, as root health is vital to the success of a crop. Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22 degrees C or 65 - 72 degrees F is recommended.
The hand held pH pen provides a compact quick and handy way to manage the success of your crop to ensure maximum uptake of nutrients.
Teamed with our Bluelab ppm or EC Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health.
Why is measuring pH vital to the success of your crop?

Bluelab pH Pen Questions & Answers
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.
