The Bluelab pH Pen is the latest innovation for hand held pH meters and is the ultimate handy solution for measuring pH.

Hydroponic growing lets you give the best care possible to your plants. The quality of care is in your control.
The Bluelab pH Pen provides a compact, quick and handy way to manage the success of your crops to ensure maximum uptake of nutrients. Teamed with our Bluelab EC Pen or Bluelab ppm Pen, you have a handy, convenient and accurate system for ensuring optimum plant growth and health.

The Bluelab pH Pen and conductivity pen range has been specially developed as an affordable and effective option for hobby or small scale growers.

Why is measuring pH vital to the success of your crop?
Plants eat. They get their nutrition from minerals but they can only get all the minerals they need if certain conditions are right. A key thing that affects food uptake is whether your solution is acid or alkaline. We measure this in pH.

The clever little pH pen ensures you maintain the optimum pH reading that allows nutrients to be available to your plants.
Once you have measured the pH using the Bluelab pH Pen and know your plants can get at the food, you then then to measure how much food is available. This is referred to as conductivity and is measured by either ppm or EC. This is where the Bluelab EC Pen or Bluelab ppm Pen comes in.
