Growth Technology - 2.76ms Conductivity Standard
Conductivity Standard by Growth Technology has an electrical conductivity (EC) of 2.76 ms/cm ensuring that your EC/CF meter is calibrated and that it gives the correct reading when mixing nutrient solutions as too high, or too low, could have a detrimental effect on how plants grow and flower.
When using Conductivity Standard for EC meter should read 2.76, if not, it will need to be calibrated. If you’re unsure on how to carry this out, check the meters instructions
