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.

What causes a salt crust on cocopeat or growbags?
A visible crust is a reason to inspect the water and feeding system, not an exact salt measurement.

Why the root zone matters
Evaporation can leave residues near the surface or drainage edges.
01 / OBSERVE
Three checks before you change anything
- Compare source-water and feed EC
- Check for fertiliser spills and splash patterns
- Test representative root-zone samples consistently
02 / NARROW IT DOWN
Where is the deposit?
Choose the closest observation for a suggested next check.
Near feed spills
Correct mixing or delivery leaks and clean equipment appropriately.
Across many bags
Review water chemistry and nutrient management.
Only at a drying edge
Check the root-zone result before assuming the whole bag is saline.
03 / TAKE THE NEXT STEP
Leave with something useful
Use a laboratory water analysis if unwanted ions are suspected.
Keep in mind
Do not estimate sodium or potassium concentration from crust colour.
