5 kg Cocopeat Blocks and Coco Chip Blocks
The standard export format
Compression is the entire economics of coir export: you ship dense dry material rather than air and water. A 5 kg block travels at roughly a fifteenth of its working volume and expands to 70 to 80 litres with about 25 litres of water.
- Expanded volume
- 70 – 80 litres
- Low-EC grade
- Below 0.5 mS/cm
- Shelf life
- 24 months

Hydration
Compressed, hydrated, expanded
Water is introduced, hydration penetrates the block, the fibres separate, and the material expands to roughly fifteen times the volume it shipped in. One block, about 25 litres of water, 70 to 80 litres of working substrate.

At a glance
The figures buyers ask for first
- Block weight 5 kg ±5% Per block, to tolerance.
- Dimensions 300 × 300 × 120 mm ±5% tolerance. Custom sizes made to order.
- Expansion 70 – 80 L After rehydration with approximately 25 litres of water.
- Water absorption 8 – 9 × Holds up to eight or nine times its own weight in water.
Specification
Full specification
Reproduced as published. Where a row reads "available on request", that is the real answer — we confirm it against your exact specification rather than quoting an estimate.
| Attribute | Specification |
|---|---|
| Product name | Cocopeat 5 kg block (CS101) |
| Material | 100% natural coconut coir |
| Weight | 5 kg per block, ±5% tolerance |
| Dimensions | 300 × 300 × 120 mm, ±5% tolerance |
| Expansion volume | 70–80 litres after rehydration with approximately 25 litres of water |

| Secondary packaging | Strong cardboard boxes or bulk stacking; customised branding available |
| Labelling | Product and batch details printed on each block |
| Application | Hydroponics, soil conditioning, seed propagation, nursery, potting mix, landscaping, greenhouse plants, flower beds, vegetable farming |
| Shelf life | 2 years under proper storage conditions — dry, away from direct sunlight |
| Blending and packing | To buyer requirement — blend ratio, particle grade, block size, packaging and print made to order |
EC 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.
Two block types
Cocopeat block or coco chip block
The same press, the same dimensions, a different material inside and a different expanded volume.
Cocopeat block
Fine pith. The workhorse format of the coir trade.
- Expands to 70–80 litres
- Filling your own pots, beds and trays
- Blending coir with other components in your own facility
Coco chip block
Coarse husk chips. Chips occupy more space at lower density.
- Expands to 50–60 litres
- High-drainage mixes, orchids and berries
- Graded 6–12, 12–18 or 18–25 mm
Full chip grading is on the coco chips page. Blending and packing are done to your requirement.
Questions
Questions buyers ask
Quantity per container depends on block dimensions and stacking, and we confirm it against your exact specification before quoting. Ask us and we will give you the loaded figure rather than an estimate.
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 good sample is rejected.
Our standard product is unbuffered, washed with water alone. Calcium buffering is a chemical treatment we carry out only on request. The two are often confused: washing with water removes loose salts and brings EC down, while buffering uses a calcium solution to displace the sodium and potassium bound to the exchange sites. Low EC does not require any chemical at all.
Usually, yes. Send us your current specification and we will tell you honestly whether we can meet it before you order.
No to both, and we say so plainly. We wash and screen but do not heat-treat, and we do not currently test for pathogens, so we do not describe the product as pathogen-free. We do not hold organic certification.
There is no minimum. We will take a single container. Many suppliers will not quote below three or five containers, which makes trying a new source expensive. We would rather take one container that ships correctly and earn the second order.
Yes. Every container ships with the batch test report for that exact production lot, and we retain a sealed duplicate here under the same batch number, so any question about a delivery can be checked against physical material.
