Recommended Nutrient Strengths for Crops

Each different crop type needs to be grown at a specific Conductivity value (Nutrient Strength).

This ensures the crop performs at its best.

The Conductivity values can vary depending on whether the crop is a leafy, flowering or fruiting variety.

Changes in season also mean that the Conductivity value can be higher or lower.

We have attached a helpful chart below to show the recommended Conductivity value for each crop type as well as their compatibility if grown in the same growing system:

Recommended EC Levels

The nutrient strengths on the chart are shown as EC and CF values.

If a grower requires a reading in E.C, ppm 500 or ppm 700 please use the conversion chart below:
