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.

How do I check my EC meter before testing cocopeat?
A consistent meter is essential before interpreting a change in the crop.

Why the root zone matters
A faulty instrument can make a stable coir system appear to have a nutrient problem.
01 / OBSERVE
Three checks before you change anything
- Use an in-date conductivity standard
- Follow the meter's temperature and calibration instructions
- Rinse between samples and avoid contaminating standards
02 / NARROW IT DOWN
What does the check show?
Choose the closest observation for a suggested next check.
Standard reads incorrectly
Calibrate or service the instrument before testing the crop.
Readings drift in one sample
Allow equilibration and inspect the probe condition.
Two meters disagree
Compare both in the same fresh standard and units.
03 / TAKE THE NEXT STEP
Leave with something useful
Record calibration date and standard value beside crop readings.
Keep in mind
Do not calibrate with an assumed tap-water EC.
