Why did my 5 kg cocopeat block expand less than expected?

Check how volume was measured before treating a lower number as a quality failure.

THE COCOPEAT CONNECTION

Why the root zone matters

Expansion depends on grade, starting moisture, hydration and the method used to measure loose volume.

01 / OBSERVE

Three checks before you change anything

  1. Confirm nominal block weight and moisture basis
  2. Check for a dry compressed centre
  3. Compare volume using the supplier's stated method

02 / NARROW IT DOWN

What is different?

Choose the closest observation for a suggested next check.

Dry material remains

Complete hydration according to instructions before measuring.

Volume was pressed down

Repeat using the agreed loose-volume procedure.

Method matches but result differs

Keep a sample and batch details for a supplier review.

03 / TAKE THE NEXT STEP

Leave with something useful

Record water added, hydration time and the volume method alongside the result.

Keep in mind

Do not compare compacted volume with loosely filled litres.
