Raw coir naturally carries salts — mainly sodium, potassium and chloride. A high or variable EC competes with your fertiliser programme and stresses sensitive crops. Washed, low-EC cocopeat hands EC control back to the grower.
Why low EC matters
When the substrate's own EC is low and stable, your feed sets the root-zone EC — giving precise, repeatable nutrition from the first irrigation.
- Less competition with your fertiliser programme
- Safer for salt-sensitive crops and young plants
- Consistent, predictable nutrition control
Washed vs extra-washed
Standard washing suits most crops; extra-washed grades target the lowest EC for hydroponic and high-value production.
How we deliver it
Coir is aged, washed (and extra-washed on request), then EC tested with a Certificate of Analysis on every batch. We can supply to your target EC.
