Electrical conductivity (EC) is a measure used when discussing soluble salts in growing media. Buyers often request a low EC cocopeat grade for applications where salt levels need close control. The right limit depends on the crop, irrigation water, nutrient program and the test method used. A label alone cannot establish that a particular batch will meet your requirement.
What low EC and higher EC mean in a quotation
“Low EC” is a commercial description, but suppliers may test and report it differently. A washed grade is commonly requested when buyers want to reduce soluble salts. Higher EC material may be considered for different applications or after additional preparation. Neither description substitutes for a current laboratory result and a suitability assessment for your use.
Compare results using the same method
When requesting a test report, ask how the sample was collected, prepared and extracted, which water-to-material ratio was used, whether the result is reported in mS/cm and when testing took place. Compare offers only after the methods and units are aligned. You may also need pH, moisture, expansion and particle-size information to evaluate a compressed block. A single EC value does not describe all of a substrate's physical behavior.
How to review our catalog target
Our export-grade washed low EC cocopeat blocks from Indonesia and 5 kg block specification page list an EC target below 0.5 mS/cm. That figure is a catalog target, not a verified result for the current batch. The extraction method is not established by the listing. Ask for a representative sample and an agreed test method before using the number to compare offers or planning a crop.
What to include in an inquiry
Specify your intended crop or growing system, target EC and pH, required test method, acceptable moisture and particle characteristics, quantity and destination. If you need a particular certificate or inspection arrangement, state it in the B2B cocopeat exporter inquiry so its availability can be confirmed before quotation.
