Coir & preparation · WITH COBY

Are long coir fibres causing pockets in my pots?

Inspect how fibre clumps sit within the finished pot. A few visible fibres are not the same as a repeatable filling obstruction.

THE COCOPEAT CONNECTION

Why the root zone matters

Coir grades contain different proportions of pith, fibre and chips. Fibres can change handling and distribution, especially when the opening or container is small.

01 / OBSERVE

Three checks before you change anything

Compare the clumps with the agreed physical grade.
Check whether roots or moisture are uneven around the clumped area.
Observe filling for bridging, tangles or unfilled spaces.

02 / NARROW IT DOWN

What is the practical problem?

Choose the closest observation for a suggested next check.

Filling bridges over a cavity

Pause the filling process and trial a grade or handling method suited to that container opening.

Fibres are visible but distribution is even

Monitor performance and compare with the specification. Visibility alone does not establish a defect.

Clumps vary widely between pots

Review representative samples and mixing consistency before attributing every weak plant to fibre.

03 / TAKE THE NEXT STEP

Leave with something useful

Record container dimensions and the size and frequency of obstructive clumps.

Keep in mind

Do not remove every fibre by hand and assume the resulting medium still matches the tested grade.
