What Are Coco Coir Grow Bags?
Coir grow bags are open-top bags filled with coir-pith growing medium, used as a ready-to-plant substrate in hydroponic and greenhouse systems. They are the standard format for high-density, controlled-environment cultivation of greenhouse vegetables such as tomatoes and cucumbers and soft fruits such as strawberries.
Grow bags are one of the fastest-growing coir formats as commercial growers move from soil to soilless production for higher, more consistent yields.
Sizes and Specifications
Open-top grow bags are available in 5 L, 10 L and 20 L volumes. A 10 L bag measures approximately 23 × 23 × 38 cm. The coir fill is supplied at an electrical conductivity below 0.7 (1:3 ratio) and a pH of 6–7, with moisture around 20%. Low-EC buffered fill is available on request for sensitive crops.
Bag dimensions, drainage holes and fill grade can be configured to your cultivation system.
Why Growers Choose Coir Grow Bags
Coir provides a stable root environment that resists compaction across crop cycles, keeping the root zone well aerated. It acts as a clean, inert canvas for liquid nutrient regimes, giving growers full control over feeding while avoiding the soil-borne pathogens associated with field production.
Because the medium is consistent bag to bag, irrigation and nutrient dosing can be standardised across an entire greenhouse.
Export Documentation and Compliance
Coir-based growing media are classed internationally as products of plant origin, so shipments are prepared to meet the biosecurity requirements of the destination country (for example USDA-APHIS, the EU and Australian authorities). Each consignment is accompanied by a phytosanitary certificate and the required fumigation or heat treatment.
Every shipment includes a certificate of analysis covering EC, pH and moisture, along with commercial invoice, packing list, certificate of origin and bill of lading.
