Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Why do EC readings change when a sample cools?
Temperature handling is part of a repeatable conductivity measurement.

Why the root zone matters
Coir feed and drainage samples may be collected at different temperatures during the day.
01 / OBSERVE
Three checks before you change anything
- Check the meter’s temperature-compensation setting and reference temperature.
- Allow the probe and sample to stabilise according to the instrument instructions.
- Compare samples using a consistent method and record unusually hot or cold conditions.
02 / NARROW IT DOWN
What explains the change?
Choose the closest observation for a suggested next check.
Compensation settings differ
Use consistent settings before comparing meters or historical records.
Readings drift while cooling
Wait for the recommended stabilisation and repeat the measurement.
Changes remain unexplained
Verify the meter in a suitable standard before interpreting crop trends.
03 / TAKE THE NEXT STEP
Leave with something useful
Store temperature information with the raw reading when investigating discrepancies.
Keep in mind
Do not apply an assumed temperature correction on top of an already compensated reading.
