EC Meters
The electrical conductivity (EC) tells us how concentrated are the mineral salts in a nutrient solution. Achieving and maintaining the right concentration for the current growth phase is important if you want the crop to grow to its full potential.
You can take your pick from simple and professional measuring devices. It depends only on the preferences of each grower.
We highly recommend the new waterproof pocket EC tester Martini 60 with a clear LCD. Or, if you'd like to kill two birds with one stone, you can get the Milwaukee kit containing a pH and EC meter.
