Bluelab Mk2 Conductivity Truncheon (nutrient strength)

The Bluelab Conductivity Truncheon measures the strength of Hydroponic nutrient solutions. It is essential when growing hydroponics to know what the strength of the solution is before feeding your plants and while they are growing. For recommended nutrient strengths etc, please see FAQ section of our site.

To take a reading of your solution - simply place the probe head into the solution for 1-2 minutes to reach the same temperature of your nutrient. Remove from the solution and place back in to take the reading as indicated by the flashing lights. Rinse the probe after use in fresh water and clean once a week to ensure the Truncheon remains accurate.
It's great for stirring your nutrient tank too!

Please see Grow FAQ section on our Homepage for more information regarding recommended pH levels and nutrient strengths.
