Did you know that there is a quick and easy soil test that you can do to see if your plants are getting the right amount of nutrients? The Bluelab Conductivity Pen offers testing in the palm of your hand. 

This quick, compact, and innovative device makes it easy to measure the nutrient level and temperature of your nutrient solutions for improved growth and success. The pen is fully waterproof with a flat electrode for easy cleaning. Customize your readings with selectable measuring units and a hold function to ensure you can capture your data easily and accurately.

Conductivity refers to the total dissolved salts – or total ionic content – in a solution. Adding nutrients can change the amount of electricity that is passing through the substance, which increases the amount of conductivity.

The Bluelab Conductivity Pen is designed for accuracy, dependability, and customization. Choose between Celsius or Fahrenheit for temperature and EC, CF, PPM 500 (TDS), or PPM 700 for conductivity. 

Keep your plant's health close at hand with the Bluelab Conductivity Pen.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
