Biobizz Coco-Mix, 50 L

A pH-Stable Organic Coconut Fiber Substrate for Hydroponics and Coco Growing

Coco coir is made from the fibrous husk of coconuts — a renewable byproduct of coconut processing. Its physical structure creates a growing medium with high porosity and low water retention, meaning roots have consistent access to both oxygen and the nutrient solution. The natural pH of coco coir falls between 5 and 6, making it compatible with the nutrient availability range used in most hydroponic and coco-fed growing programs.

Biobizz Coco-Mix is an organic coconut fiber substrate designed for use with coco-specific nutrient programs that include organic minerals. Because coco coir is an inert substrate without the native microbiology of soil, plant nutrition is delivered entirely through the nutrient solution — making the choice of nutrient program and dosing schedule particularly important. Biobizz Coco-Mix is compatible with all hydroponic systems.

Key Features & Benefits

• Organic coconut fiber substrate — made from coconut husks — a natural, renewable fiber with physical properties suited to hydroponic and coco growing.
• pH 5–6 — natural pH falls in the 5–6 range, compatible with the nutrient availability window used in coco and hydroponic growing programs.
• High air porosity, low water retention — coconut fibre structure allows more air volume around the root zone, supporting root oxygen levels while the nutrient solution drains freely.
• Compatible with all hydroponic systems — suitable for use in all hydroponic systems including drip, NFT, flood and drain, and hand-watered coco setups.
• Use with coco nutrient programs — designed for use with coco-specific nutrient products containing organic minerals to provide the full mineral profile plants need in an inert substrate.
• 50-liter bag — sufficient for multiple medium-sized containers or one large container depending on pot size and system configuration.

Who Should Use Biobizz Coco-Mix 50 L

Growers who prefer the physical properties of coco coir — high air porosity and drainage — over soil-based substrates, and who are running hydroponic or coco-fed growing programs with organic coco nutrients.

Coco Coir vs. Soil: Key Differences for Growers

Coco coir differs from soil in two important ways: it is an inert substrate with no native nutrient content, and it has a lower water-holding capacity. This means the plant receives nutrients exclusively from the nutrient solution, and the grower has direct control over the nutrient program from day one. Coco also requires more frequent watering than soil to maintain moisture in the root zone. Use a coco-specific nutrient program when growing in Coco-Mix.

Frequently Asked Questions

Do I need a special nutrient program for coco coir?

Yes — because coco coir is an inert substrate without native nutrients or microbiology, plants rely entirely on the nutrient solution for their mineral supply. Use a coco-specific nutrient program that accounts for coco's tendency to buffer calcium and magnesium. Biobizz recommends using Coco-Mix with coco nutrients containing organic minerals.

Is coco coir pH-neutral?

Coco coir has a natural pH between 5 and 6. This is slightly acidic, which falls within the nutrient availability window used in most hydroponic and coco programs. Unlike some inert media, it does not require significant pH adjustment before use, but the nutrient solution should still be pH-checked before application.

How often do I need to water plants in coco coir?

Coco coir holds less water than soil, so plants in coco typically require more frequent watering. In most grow setups, daily or twice-daily watering is common depending on plant size, environment, and container volume. The high air porosity of coco helps prevent root issues from overwatering if drainage is adequate.

Can I use Biobizz soil nutrients with Coco-Mix?

Coco coir requires a coco-specific nutrient approach because it can sequester calcium and magnesium from soil-formulated nutrient products. Biobizz recommends using coco nutrients containing organic minerals with their Coco-Mix substrate rather than soil fertilizer programs.
