Coir & preparation
Washing or buffering?
A low EC result and a buffering treatment answer different questions. Confirm both on the product specification before deciding how to prepare your cocopeat.

How can I calculate cocopeat cost per usable litre?
Use trial-measured usable volume to understand the effective material cost. Keep the calculation separate from unverified expansion claims.

Why the root zone matters
Hydration and filling practices determine how much coir is actually available for your containers.
01 / OBSERVE
Three checks before you change anything
- Measure usable litres from representative units using one filling method.
- Record any unusable fraction and the cost of preparation or handling separately.
- Divide the relevant material cost by the usable volume on the same batch basis.
02 / NARROW IT DOWN
Which volume do you have?
Choose the closest observation for a suggested next check.
Only advertised expansion
Run a representative expansion trial before relying on a precise cost-per-litre figure.
Measured loose volume
Keep the moisture and filling method in the calculation notes so comparisons remain consistent.
Finished container yield
Use the number of consistently filled containers and their working volume as an operational comparison.
03 / TAKE THE NEXT STEP
Leave with something useful
Record both purchase price and preparation costs beside the measured usable volume.
Keep in mind
Do not mix a dry compressed weight basis with an assumed wet-volume conversion.
