HortGrow Bulk Compressed Coco — 5kg (11lb) — Expands to 90L

HortGrow Bulk Compressed Coco — 5kg Block — Expands to 90L

HortGrow Bulk Compressed Coco is a premium-grade compressed coco coir block designed for commercial growers, large-scale indoor cultivation facilities, and serious home growers who want the maximum value and flexibility of bulk coco coir in a highly compact, easy-to-handle format. Each 5kg (11lb) compressed block expands to approximately 90 liters of loose, ready-to-use coco growing media when hydrated — providing a large volume of consistent, professionally processed coco coir that can be used directly as a growing medium, as a component in custom growing media blends, or as a base for coco-perlite mixes.

Like all HortGrow coco products, the Bulk Compressed Coco is triple-washed and calcium-magnesium buffered during processing to remove excess soluble sodium and potassium — delivering a clean starting EC and balanced pH that minimizes pre-use preparation and allows growers to get their nutrient program established faster and with greater precision.

Key Features & Benefits

• High-Compression Bulk Format: The 5kg compressed block reduces the shipping volume and storage footprint of 90 liters of coco coir to a fraction of its expanded size — making it highly cost-effective to transport and store compared to pre-expanded coco bags of equivalent volume.
• 90L Expansion Volume: Each block expands to approximately 90 liters of loose coco growing media — sufficient to fill multiple large containers or a significant number of smaller growing vessels, making it ideal for operations that regularly prepare growing media in large batches.
• Triple-Washed & Buffered: HortGrow's multi-stage washing and calcium-magnesium buffering protocol removes excess sodium, potassium, and soluble salts from the raw coco fiber — delivering a clean starting EC and near-neutral pH that requires minimal adjustment before use with your nutrient program.
• Custom Blending Flexibility: Bulk loose coco is the ideal base medium for custom growing media blends. Mix with perlite, vermiculite, coco chips, or other amendments to create tailored growing media profiles for specific crop requirements, root zone structures, or system types.
• Consistent Fiber Quality: HortGrow's processing standards ensure consistent particle size, moisture content, and buffering level across every block — providing reliable, predictable performance batch after batch for commercial operations that depend on media consistency.

Who Should Use This

HortGrow Bulk Compressed Coco is the smart choice for commercial indoor cultivation facilities that mix their own growing media, large-scale growers who go through significant coco coir volume each cycle, and any operation that values the cost efficiency and storage compactness of a bulk compressed format. Home growers who want maximum value per dollar and regularly blend their own custom coco media will also benefit from the bulk compressed block.

Compatibility

Compatible with all hydroponic nutrient programs and growing system types. Expand fully with clean water before use and allow excess water to drain. Can be used alone or blended with perlite, coco chips, vermiculite, or other media components. Triple-washing and buffering reduce but do not eliminate the need to flush and check EC before planting.

Frequently Asked Questions

How do I expand the compressed coco block?

Place the compressed block in a large container or on a tarp. Slowly add clean, pH-adjusted water — the block will absorb water and begin to expand within minutes. Continue adding water gradually until the block has fully broken apart and expanded to its full 90-liter volume. Mix by hand or with a tool to ensure even hydration throughout. Allow excess water to drain before use.

How much water does it take to fully expand the block?

Approximately 15–20 liters of water is typically required to fully expand a 5kg compressed coco block to its 90L volume, though this can vary depending on the initial moisture content of the block. Add water gradually and allow it to absorb fully between additions.

Does bulk coco coir need additional buffering before use?

HortGrow's coco is pre-buffered with calcium and magnesium during production, which significantly reduces sodium and potassium levels. However, it is always recommended to flush your expanded coco with nutrient solution and check the runoff EC before planting to confirm the media is fully primed and within your target range.

Can I mix this with perlite for a coco-perlite blend?

Yes. Bulk expanded coco coir is the ideal base for a coco-perlite blend. A common ratio is 70% coco to 30% perlite by volume, which improves drainage and aeration compared to pure coco. Adjust the ratio based on your irrigation frequency and the specific requirements of your crop.

How should the compressed block be stored before use?

Store compressed coco blocks in a cool, dry location away from direct sunlight and moisture. The compressed block will remain viable for extended periods when stored properly. Once expanded, use promptly or store the hydrated coco in a clean, sealed container to prevent contamination.
