Cocopeat Manufacturer in Tamil Nadu, India

Cocopeat is the fine pith left after coir fibre is separated from the coconut husk. It holds several times its own weight in water, drains without collapsing, and resists compaction over a long crop cycle — which is why it replaced peat as the standard substrate across much of protected horticulture.

That description fits every supplier’s product. What actually separates them is narrower and less glamorous: how much salt is left in it, how consistent the particle size is, how wet it is when it reaches you, and whether any of that was measured before it shipped.

A grower can design a fertigation programme around almost any substrate, provided it behaves the same way in every delivery. The problems start when it doesn’t.

Coconuts grow in coastal soils and husk is often processed near the sea, so raw pith carries a significant load of sodium, potassium and chlorides. Electrical conductivity is simply a measure of how much of that is present.

We rinse in stages rather than once, and we record EC at each stage rather than only at the end. That matters more than it sounds: if a batch comes out high, a single end-of-line reading tells you that it happened, while stage readings tell you where it happened — a short rinse, a water quality change, or material that arrived unusually saline. One is a number; the other is something you can fix.

Washed low-EC grade is achieved with water alone. More than six rinse stages across roughly a week bring EC below 0.5 mS/cm, with no chemical treatment of any kind. Standard unwashed grade sits above 0.5 mS/cm and suits buyers who wash or blend in their own facility.

All our EC figures are measured by the 1:1.5 volume extract method. If your specification uses saturated media extract, tell us and we will supply the equivalent figure — the two differ by roughly a factor of two, and it is the most common reason a perfectly good sample gets rejected.

Washing removes the salts that are loose in the material. It does not remove the sodium and potassium bound to the cation exchange sites — the places where a substrate temporarily holds nutrients before releasing them to roots.

Buffering soaks washed pith in a calcium solution so that calcium takes those sites before the material reaches a grower. Without it, your feed slowly does the job instead: calcium and magnesium disappear into the substrate while potassium appears from nowhere, and the grower spends weeks chasing a nutritional problem that came from the medium rather than the schedule.

Our standard product is unbuffered, washed with water only. Calcium buffering is a chemical treatment we carry out only when a customer specifically asks for it, and it is worth knowing that buffered material can no longer honestly be described as chemical-free.

Unbuffered suits substrate companies and larger growers who buffer to their own recipe, and it ships lighter and cheaper. Buffered suits long-cycle, high-value crops and automated fertigation with little room to compensate early on.

Full explanation, including when unbuffered is the better and cheaper answer for you, is on our buffered vs unbuffered guide.

Particle grades. Screened to fine, medium and coarse. Fine holds the most water and suits propagation, nursery work and small pots. Coarse drains faster and blends better with chips. A defined particle distribution can be produced where your specification calls for one.

Blending. Cocopeat is combined with coco chips to set the balance between water buffer and root-zone air. Across our range that moves from 5.2% air-filled porosity at 100% cocopeat to 30.8% at 100% chips, with water holding capacity falling from 7.32 to 4.77 L/kg as chip content rises. Any ratio between those points is available — we blend to order rather than to a catalogue.

Formats. 5 kg blocks expanding to 70–80 litres, 600 g bricks expanding to 8–10 litres, grow bags and slabs, open-top planter bags, and loose material in bulk.

pH sits naturally between 5.5 and 6.8. Note that this is above the ideal range for blueberry, which is covered on our blueberry page.

Blending and packing are done to your requirement. Ratio, particle grade, compressed dimensions, pack format, labelling and print are all made to order — tell us what your crop and your handling line need.

Cocopeat is a natural material and, in its unbuffered form as we currently supply it, has no chemical additives. But we do not hold organic certification, and buffered material is treated with calcium nitrate, which means it cannot honestly be described as chemical-free.

We do not heat-treat or sterilise, and we do not currently test for pathogens, so we do not describe our product as pathogen-free. If your programme requires certified sterilised or certified organic material, tell us before you order and we will say plainly whether we can supply it.

We would rather lose an order than have a container rejected at your end. How we test and document each batch is on the quality and laboratory page.
