Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Is low EC cocopeat already buffered?
A low EC result and a buffering treatment answer different questions. Confirm both on the product specification before deciding how to prepare your cocopeat.

Why the root zone matters
Washing reduces soluble salts. Buffering conditions coir’s exchange sites, usually using calcium to displace potassium and sodium. An EC meter alone cannot confirm that process.
01 / OBSERVE
Three checks before you change anything
- Read the batch specification: washed, low EC and buffered are separate claims.
- Check the EC extraction method and units before comparing a supplier result with your own test.
- Ask for preparation instructions and a crop-appropriate feeding plan. Do not assume every block or loose bag has the same treatment.
02 / NARROW IT DOWN
What does your specification say?
Choose the closest observation for a suggested next check.
Buffered, with batch details
Follow the supplier’s hydration and planting instructions. Confirm water quality and the nutrient programme; do not automatically repeat buffering.
Washed or low EC only
Ask the supplier whether buffering was carried out. Agree suitability and any preparation with your adviser before planting.
Treatment is unknown
Keep the batch identifiable. Request its treatment record and laboratory specification before committing a commercial crop.
03 / TAKE THE NEXT STEP
Leave with something useful
Gather the batch number, treatment declaration and EC report with its extraction method.
Keep in mind
Do not treat a low soluble-salt reading as proof of buffering or apply an unverified chemical recipe.
