GROWING MEDIUM
Washed, sieved and low EC coconut coir substrates for professional growers. Buffered with calcium and magnesium on request, shipped with full export documentation.
Coconut coir growing medium from Indonesia
Coconut coir is the fibre and pith recovered from coconut husk, the part of the fruit most processors treat as waste. Washed, sieved and graded, it becomes a growing medium with high water holding capacity, good air porosity and a structure that does not collapse over a season the way peat does. It is also renewable, which matters more every year in markets where peat extraction is being restricted.
You will see the same material sold as cocopeat, coco peat, coir peat and coco coir. The name changes by market and by supplier. The specification is what matters, and that is what this page sets out.
Indo Coco Flourish supplies growing media in bulk from Indonesia to importers, substrate blenders, potting soil producers, commercial nurseries and retail brands. We ship FOB or CIF from Surabaya with full export documentation.
Choosing a format
Most buyers arrive knowing they want coir and unsure which format suits their operation. The practical difference is how much water and air you are paying to ship, and how much handling the product needs at your end.
| Format | Expansion | Packing | Typically bought by |
|---|---|---|---|
| Loose coir | Ready to use, uncompressed | 50L, 175L bagger, 1500L jumbo | Substrate blenders, nurseries, potting soil producers |
| 5kg coir block | Roughly 65 to 90 litres | POF wrap, handle bag or unwrapped | Greenhouses, professional growers, blenders shipping long distance |
| 650g coir brick | Roughly 8 to 9 litres | POF wrap, 6-pack handle bag or unwrapped | Garden centres, retail brands, seed starting ranges |
| Coir perlite mix | Ready to use, 70/30 blend | 20L, 50L, 1500L jumbo | Greenhouse growers, high value crops, nurseries |
| Coir fibre pole | Not applicable | Bundled or master cartons | Plant retailers, garden centres, indoor plant brands |
If you are shipping across an ocean, compressed blocks almost always win on landed cost per litre of finished medium. If you are filling trays or pots on arrival with no hydration line, loose coir saves you a processing step.
EC, pH and buffering
Electrical conductivity is the specification that causes the most problems in coir, and the one worth understanding before you order.
Coconuts grow in coastal soils, so raw coir carries sodium and potassium. EC measures the soluble salt left in the material after washing. Our washed low EC grade is under 0.5 mS/cm, which suits seedlings, hydroponic systems and crops that will not tolerate salt stress. Our high EC grade sits at 0.7 mS/cm and above, costs less, and is a sensible choice where the grower is managing nutrition actively or the crop is tolerant.
pH across our growing media runs 5.5 to 6.8, inside the range most horticultural crops prefer.
Buffering is a separate step from washing. Calcium and magnesium are introduced to displace sodium and potassium held on the coir exchange sites, so those salts do not release into your nutrient solution later in the crop cycle. Our coir perlite mix is buffered as standard. Other media can be buffered on request.
Quality control and testing
Quality in coir is a measurement, not an adjective. Our coir peat is independently tested by PT Saraswanti Indo Genetech (SIG), a KAN accredited laboratory, with a batch report available per container.
Where a destination market sets its own requirements, we test to those instead. Australian imports require Salmonella and E. coli status for each shipment and we supply that analysis through Sucofindo. Tell us the destination market at enquiry stage and we will confirm what testing your import needs.
Every container ships with a phytosanitary certificate issued by Indonesian plant quarantine, a certificate of origin and a PEB export declaration. Fumigation certificates and ISPM 15 compliant packaging are available on request.
Private label and custom specification
Beyond bulk supply we manufacture to buyers own specifications and pack under buyers own brands. That covers custom EC levels, sieve grades, block and brick dimensions, blend ratios and printed retail packaging. See OEM and private label for the process, artwork requirements and payment structure.
Ordering and export
- Minimum order: 1 x 20ft container per product. A 40ft high cube is usually better value per unit.
- Lead time: 3 to 4 weeks after order confirmation for growing media.
- Incoterms: FOB or CIF preferred, EXW also supported.
- Loading port: Surabaya, Indonesia.
- Container quantity: confirmed at quotation, since destination road weight limits vary by country.
Send us your requirement with product, specification, quantity and destination port and we will come back with a quotation. Samples are free and you cover the courier.
