The Commercial Truncheon measures the strength of a nutrient solution, just like the Bluelab Truncheon. The Commercial Truncheon however, has been designed for hydroponic crops that require a higher than normal EC or CF requirement during their growing cycle. A reading of up to 6.0EC or 60CF is available.

It is essential when growing hydroponics to KNOW what the strength of the solution is before feeding your plants AND while they are growing.
Great for stirring your nutrient tanks too!
