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 should I send a fertiliser solution sample to a laboratory?
Ask the laboratory what sample, bottle and handling conditions it requires.

Why the root zone matters
A labelled final-feed sample can help determine what the cocopeat crop actually receives.
01 / OBSERVE
Three checks before you change anything
- Specify whether you are testing source water, stock concentrate or final feed.
- Collect at a documented location during stable operation.
- Record recipe, dilution, collection time and any storage instructions from the laboratory.
02 / NARROW IT DOWN
Which solution is being tested?
Choose the closest observation for a suggested next check.
Final feed
Record the active zone and sample location so the result can be compared with crop records.
Stock concentrate
Confirm that the laboratory accepts and can handle the concentration safely.
Unknown tank contents
Identify and label the material accurately before arranging analysis.
03 / TAKE THE NEXT STEP
Leave with something useful
Send the preparation and sampling record with the sample.
Keep in mind
Do not send an unlabelled concentrate as though it were ordinary irrigation water.
