THE COCOPEAT CONNECTION

Why the root zone matters

Water tension and water content are different measurements in a coir root zone.

01 / OBSERVE

Three checks before you change anything

  1. Follow the manufacturer’s preparation and contact instructions.
  2. Compare readings with crop response and other moisture observations.
  3. Inspect service needs and any loss of water column or air entry.

02 / NARROW IT DOWN

What is the issue?

Choose the closest observation for a suggested next check.

Reading stays unchanged

Check the instrument and contact before assuming moisture is constant.

Reading changes after relocation

Treat the new position as a new baseline and compare it with the previous location.

Instrument performs consistently

Develop crop-specific interpretation with the adviser rather than borrowing a generic trigger.

03 / TAKE THE NEXT STEP

Leave with something useful

Keep maintenance and installation records alongside readings.

Keep in mind

Do not translate a tension reading into a universal percentage of water without a validated relationship.
