Nutrient strength is measured in EC (electrical conductivity) or CF (conductivity factor). 

1 CF is the same as 0.1 EC. Really, they tell you the same thing – how many dissolved salts are in your solution.

So the stronger your feed, the higher the CF/EC reading will be.

If your CF is too low, plants may not be getting enough nutrients. If it’s too high, plants can dehydrate.

The best nutrient strength to aim for depends on how hard your water is and what stage of growth you’re at. As a rough guideline, aim for:

• Young plants = 6 – 12 CF (0.6 - 1.2 EC)
• Establishing plants = 10 – 16 CF (1.0 - 1.6 EC)
• Mature plants = 15 – 20 CF (1.5 - 2.0 EC)

To measure conductivity, place the probe into nutrient solution and take reading as indicated by the flashing lights.

If the lights are dancing between two values, the reading is between those two values (e.g. lights dancing between ‘6’ and ‘8’ indicates a reading of ‘7’)

Note:

For very cold or very hot temperatures it will take 1-2 minutes for the probe to reach solution temperature.

To help decrease time taken to reach the solution temperature, place the probe in an area where there is lots of movement.

Cleaning:

We recommend the probe be cleaned once every two weeks according to the cleaning and maintenance instructions provided with your meter. This can vary depending on frequency of use.
