These blocks are often used in commercial settings where consistent water availability is crucial and frequent rehydration is impractical.

Loose Fiber

Produced through mechanical processing of coconut husks, loose fiber coco peat has a naturally airy and fibrous structure. This texture promotes excellent root aeration and rapid root penetration, making it ideal for starting seeds, nurturing young seedlings, or blending into soilless mixes.

Because it’s already expanded, loose fiber eliminates the need for hydration, saving time and labor—especially beneficial in nurseries and propagation centers.

Compressed Bales

Compressed bales are large-scale packaging units of coco peat, typically weighing between 5–10 kg or more. Designed for commercial agriculture, landscaping, and large garden projects, these bales offer high volume at low cost per unit.

Once opened and hydrated, a single bale can yield hundreds of liters of usable growing medium. Their efficiency in bulk handling makes them a top choice for farms, greenhouses, and municipal gardening operations.

Pellets

Coco peat pellets are small, disc-shaped units (usually about 1 inch thick) compressed with a central cavity for seeds. When water is added, the pellet expands into a self-contained planting pot, eliminating the need for additional containers during germination.

These are widely used in home gardening kits, educational projects, and commercial nurseries due to their convenience, consistency, and minimal waste. Some pellets include a biodegradable netting that breaks down in soil.

Husks

Coco peat husks refer to whole or chopped pieces of coconut husk, used primarily as mulch or compost additive. When spread over soil, they help reduce evaporation, suppress weeds, and regulate soil temperature.

In permaculture and organic gardening, husks are also incorporated into garden beds to improve soil structure and provide slow-release organic matter as they decompose. They are especially effective in arid climates where moisture retention is critical.

Netted Bricks

Netted bricks are coco peat bricks wrapped in a biodegradable or synthetic mesh netting. The netting provides structural integrity during expansion and enhances drainage, making them particularly suitable for hydroponic systems, drip irrigation setups, and vertical gardening.

The mesh allows roots to penetrate easily while preventing the medium from dispersing, offering both support and aeration. This design is favored in controlled-environment agriculture and automated growing systems.
