Low EC and high EC cocopeat compared
Low EC and high EC are the two preparations most cocopeat is sold in, and the choice between them is the first thing a quotation depends on. This guide explains what the terms describe, who normally picks which, and why this site does not publish a value for either.

What EC describes
EC stands for electrical conductivity. It is a measurement of how easily an electric current passes through a solution, and because dissolved salts carry that current, it is used as an indicator of how much soluble salt a growing medium contains.
Coconut husk naturally contains soluble salts. How much of that remains in the finished cocopeat depends on whether the material has been washed, and how thoroughly.
The two preparations
- Low EC cocopeat
- Material that has been through a washing step to reduce the soluble salt content. Selected where a lower salt level is wanted in the medium as supplied.
- High EC cocopeat
- Natural material supplied without that washing step. Selected by buyers who wash, buffer or blend after arrival, and by applications where the salt level matters less than the base cost.
High EC is not a lower grade. It is a different starting point, and for a buyer who runs their own treatment step it is often the correct one.
Who normally chooses which
- Hydroponic and controlled environment growers
- Usually low EC, because irrigation water chemistry is managed closely and the substrate is under constant feed.
- Propagation and young plant nurseries
- Usually low EC, because young roots are the least tolerant stage.
- Substrate and potting mix manufacturers
- Either, depending on whether the treatment step sits in their own process.
- Soil conditioning, bulking and landscaping supply
- Often high EC, where the material is not the sole root zone.
This is a pattern, not a rule. Confirm the choice against your own system rather than against a table.
Buffering is a separate step
Washing and buffering are often spoken about as though they were the same thing. They are not. Washing reduces the salts that will dissolve out of the material. Buffering is a further treatment intended to address ions held on the material itself.
Some buyers want material that has only been washed, because they run their own buffering to their own recipe. Tell us which applies to you during quotation, because it changes which material is selected for your order.
Why no value is published here
Cocopeat is a natural material. Its salt content varies with the husk, the season, the water used to wash it, and how long the material was worked. A single number published on a website describes one batch at one moment.
Agrorise does not publish a figure for this until it has been confirmed against your order. Where you see "Confirmed during quotation" on this site, it means the value depends on the material selected and the specification agreed with you, not that the information is being withheld.
If you need a value committed for your order, ask for it in the quotation and it will be addressed there, against the material actually being offered to you.
