Roots & watering
Uneven watering or dry bags
When one bag dries while its neighbour stays wet, start by comparing water delivery. Increasing irrigation everywhere can make the wet areas worse.

What does a rising filter pressure difference mean in fertigation?
Compare pressure before and after the filter under the same operating conditions.

Why the root zone matters
Restricted flow upstream can affect water and feed delivery to every cocopeat bag in a zone.
01 / OBSERVE
Three checks before you change anything
- Check that both pressure readings are taken while the same zone runs.
- Compare with the filter manufacturer’s service criteria and a clean-system baseline.
- Inspect water-source changes and the material captured during routine servicing.
02 / NARROW IT DOWN
What is the pattern?
Choose the closest observation for a suggested next check.
Difference rises during operation
Service or backwash according to the filter instructions and verify the readings afterward.
Both readings fall together
Investigate the supply or pump rather than blaming only the filter.
Readings are erratic
Check gauge condition and operating stability before drawing conclusions.
03 / TAKE THE NEXT STEP
Leave with something useful
Record the pressure difference and servicing date in the irrigation log.
Keep in mind
Do not bypass a filter to regain flow without an approved replacement protection plan.
