BioBizz Light Mix 90L Organic Growing Substrate

BioBizz Light Mix 90L – Organic Growing Substrate

BioBizz Light Mix 90L is a lightly fertilised organic growing substrate designed for growers who want greater control over plant nutrition from the beginning. The new extra-large 90 litre bag provides the proven characteristics of BioBizz Light·Mix® in a larger, more economical format for higher-volume growing.

With a light nutrient charge and an aerated, free-draining structure, BioBizz Light Mix provides an excellent foundation for seedlings, young plants and cuttings while remaining suitable throughout the rooting, vegetative and flowering stages.

Unlike heavily pre-fertilised substrates, Light Mix gives the grower greater control over the nutrients applied throughout the growing cycle. This makes it particularly suitable for customised feeding programmes where nutrient strength is adjusted according to plant development.

Why Choose BioBizz Light Mix 90L?

• New extra-large 90 litre bag – ideal for growers requiring larger quantities of substrate.
• Lightly fertilised growing medium providing greater control over nutrient application.
• Suitable for seedlings, cuttings and young plants from the beginning.
• Supports healthy root establishment and development.
• Encourages beneficial biological activity within the growing medium.
• Excellent drainage and aeration help create a favourable root-zone environment.
• Suitable for indoor and outdoor horticulture.
• Suitable throughout rooting, vegetative growth and flowering.
• Well suited to regular watering and compatible automatic irrigation strategies.
• Allows greater control over feeding compared with heavily pre-fertilised growing substrates.

Greater Control Over Plant Nutrition

BioBizz Light Mix is designed for growers who prefer to control their own feeding programme rather than relying on a heavily pre-fertilised substrate.

Its relatively light initial nutrient charge provides a flexible foundation from which additional fertilisers can be introduced according to plant size, growth stage and nutritional requirements.

This makes Light Mix particularly useful when working with young plants or implementing a carefully controlled feeding programme from an early stage.

Ideal for Seedlings, Cuttings & Young Plants

Young plants require a suitable balance of moisture, air and nutrition while their root systems become established. BioBizz Light Mix provides a lightly fertilised environment that encourages the development of a healthy root structure without starting plants in an excessively rich growing medium.

When water enters the substrate, it interacts with the organic components and helps stimulate the biological activity within the growing medium.

This active root-zone environment makes Light Mix particularly suitable for:

• Seedlings
• Cuttings
• Young plants
• Root establishment
• Vegetative growth
• Flowering plants
• Indoor horticulture
• Outdoor container growing

Excellent Drainage & Root-Zone Aeration

BioBizz Light Mix is specially blended to provide effective drainage throughout the growing medium. Maintaining the correct balance between moisture and oxygen is important for creating a healthy root-zone environment.

The free-draining structure is particularly beneficial when using automatic irrigation systems, where water needs to infiltrate evenly through the substrate without leaving areas excessively saturated.

Good irrigation management remains important. Allowing the substrate to remain excessively wet can reduce root-zone aeration and create conditions that encourage mould and other moisture-related problems.

Designed for Flexible Feeding Programmes

Because Light Mix begins with a relatively light nutrient charge, growers have greater flexibility when introducing additional plant nutrition.

BioBizz specifically positions Light Mix for growers who want greater control over feeding, including plants with higher nutrient requirements. Nutrient strength should still be introduced appropriately according to plant age, condition and environmental requirements.

This flexibility makes Light Mix a useful choice for growers who prefer to manage nutrition throughout the crop cycle rather than begin with a heavily enriched substrate.

pH & EC Characteristics

BioBizz Light Mix contains natural organic components rather than relying on the mineral salt concentrations associated with conventional synthetic fertilisers.

According to BioBizz, Light Mix has a medium electrical conductivity (EC) and its organic components provide a self-regulating system that helps maintain suitable pH conditions within the growing medium.

Suitable for Automatic Irrigation

The drainage characteristics of BioBizz Light Mix make it suitable for use alongside correctly configured automatic watering systems.

When using automated irrigation, ensure water is distributed and absorbed evenly throughout the substrate. Irrigation frequency and volume should be adjusted according to container size, plant requirements and environmental conditions to avoid prolonged saturation.

Indoor & Outdoor Growing

BioBizz Light Mix is suitable for both indoor and outdoor horticulture and can be used throughout multiple stages of plant development.

New 90 Litre Extra-Large Format

The new BioBizz Light Mix 90L provides significantly more growing medium per bag than the established 50 litre format, making it particularly convenient for larger containers, multiple plants and higher-volume horticultural applications.

A single 90 litre bag provides:

• 50% more substrate than two 30 litre bags.
• 80% more substrate than one 50 litre bag.
• Enough substrate to fill approximately nine 10 litre containers.
• Enough substrate to fill approximately six 15 litre containers.
• Enough substrate to fill approximately four 20 litre containers with some substrate remaining.

Actual container requirements may vary depending on filling level, substrate settlement and pot design.

How to Use BioBizz Light Mix

1. Fill the required container with BioBizz Light Mix without excessively compacting the substrate.
2. Position the plant or established cutting within the growing medium.
3. Water evenly to ensure moisture is distributed throughout the root zone.
4. Allow appropriate drainage after watering.
5. Introduce additional nutrition according to plant requirements and the chosen feeding programme.
6. Monitor moisture levels before subsequent irrigation to avoid keeping the substrate excessively wet.

Best Practice

• Avoid excessively compressing the substrate when filling containers.
• Water evenly throughout the growing medium.
• Ensure containers provide adequate drainage.
• Adjust irrigation frequency according to plant size, container volume and environmental conditions.
• Avoid allowing the substrate to remain continuously saturated.
• Introduce nutrients according to plant requirements rather than assuming a fixed feeding strength.
• When using automatic irrigation, ensure water infiltrates evenly throughout the substrate.
