PH values in water indicate the level of alkalinity. Depending on the pH value, plants will have higher or lesser ability to absorb nutrients. An optimal pH level is 6.2, and may range between 5.8 and 6.5. The EC, electro conductivity, measures the amount of electrical conductivity of water in a plant. It is really useful to know if the roots are absorbing nutrients properly as well as important metering issues such as pH value or the amount of light. An optimal EC level in a cannabis culture may range between 0.60 and 2.00 mS.

We have pH and EC meters of all prices and qualities. All of them are very precise.
