It is essential when growing with a hydroponic solution to KNOW what the
strength of the solution is before feeding your plants AND while they are
growing. If the conductivity reading is too low, your plants may not be getting
enough nutrients. If the conductivity reading is too high, plants can
dehydrate.
Understanding the conductivity of the nutrient solution takes the
guesswork out of feeding plants. It will also save you money! Using the Bluelab
Truncheon® Nutrient Meter is the fastest and easiest way to measure the
conductivity!
To take a reading of your solution - simply place the probe head into the solution and the reading is indicated by the flashing lights. Calibration of the Truncheon® Nutrient Meter is not required.
Meter length: 40.7cm or 16 1/32 in.
