THE COCOPEAT CONNECTION

Why the root zone matters

Cube volume and dimensions affect handling, moisture reserves and how the roots reach the next medium.

01 / OBSERVE

Three checks before you change anything

  1. Check expanded dimensions against the tray
  2. Plan the nursery duration
  3. Trial the transplant fit and irrigation contact

02 / NARROW IT DOWN

Which constraint matters most?

Choose the closest observation for a suggested next check.

Tray fit

Measure the actual cavity before ordering.

Long nursery stage

Review root volume and irrigation needs over the full period.

Transfer to a slab

Check stable placement and root contact at transplanting.

03 / TAKE THE NEXT STEP

Leave with something useful

Trial the cube from sowing or rooting through transplant.

Keep in mind

The largest cube is not automatically the best choice.
