Cocomix blueberry substrates are engineered for modern commercial production. An excellent balance between Water Holding Capacity and Air-Filled Porosity creates the ideal environment for healthy blueberry root development, from planting through to premium fruit.
Berry Master open-top planter bags are specially engineered for high-performance blueberry (Vaccinium) production. A premium blend of coco peat and coco chips delivers the optimum balance of water holding and air-filled porosity for healthy roots and consistent growth.
Engineered for an excellent balance between Water Holding Capacity (WHC) and Air-Filled Porosity (AFP), creating an ideal environment for healthy blueberry root development.
A carefully selected combination of coco peat and coco chips provides excellent root-zone structure, encouraging stronger root growth, better branching and improved nutrient uptake.
Maintains consistent moisture around the roots while allowing excess water to drain efficiently, reducing the risk of waterlogging and root-zone stress.
High-quality coco chips maintain their structure over the full production cycle, retaining porosity and drainage characteristics for long-term blueberry cultivation.
Developed for commercial blueberry production, Cocomix blueberry substrates are designed for modern commercial operations, with options such as HRGST (High Root Growth Stimulating Technology) to support vigorous root-zone development and consistent crop performance.

A completely self-contained solution built on a 27L Vaccinium premium grow bag crafted with custom integrated coco peat and chip blends. It eliminates the need for external rigid pots, drastically reducing initial setup costs and allowing lightning-fast block setup.
Available in 27L, 30L, 35L and 40L, with volumes tailored to customer requirements. Our carefully screened substrate, durable raw materials and 800+ gauge UV-stabilised bags ensure excellent root growth, durability and long service life.


An ideal solution for commercial growers using permanent plastic pots. The raw compressed refill blocks drop cleanly into standard pots and are filled with premium Berry Master coir substrate, delivering the right balance of WHC and AFP for strong root development and healthy blueberry growth, without plastic bag waste.
In collaboration with Bato Plastics, Netherlands, we offer a reliable, high quality and competitively priced solution for professional blueberry growers.

The Berry Master Vaccinium coconut coir open-top bag is designed with two specialised layers to optimise blueberry plant growth.
Top Layer: BM-0307
Enriched with higher peat content and fewer coconut chips for root anchorage and development. WHC 55-60% (V/V), AFP 30-35% (V/V).
Bottom Layer: BM-0703
Multigrain structure with lower peat content and more compressed coconut chips for efficient drainage. AFP 80-85% (V/V), WHC 20-25% (V/V).
