BioBizz All Mix 90L Pre-Fertilised Organic Growing Substrate

BioBizz All Mix 90L – Pre-Fertilised Organic Growing Substrate

BioBizz All Mix 90L is a heavily pre-fertilised organic growing substrate designed to create a rich, biologically active root-zone environment from the start. The new 90 litre extra-large bag provides the proven BioBizz All·Mix® growing medium in a larger format for growers filling multiple pots or larger containers.

Designed to emulate the characteristics of rich outdoor soil, BioBizz All Mix combines organic ingredients with Pre·Mix™ to create an active growing medium containing sufficient initial nutrition to support established plants during their first weeks of growth.

Unlike lightly fertilised substrates where additional nutrition may be introduced relatively early, All Mix provides a nutrient-rich starting point and is designed to reduce the need for additional fertiliser during the initial establishment period.

• Designed for use throughout vegetative growth and flowering.

A Rich, Biologically Active Growing Medium

BioBizz All Mix is designed to reproduce many of the characteristics associated with naturally rich outdoor soil. Rather than functioning simply as a physical support for roots, the substrate provides an active environment containing organic nutrition and beneficial microbial activity.

When correctly prepared and maintained, the microorganisms within the substrate help create a biologically active root zone where organic components can interact with water, air and plant roots.

This makes All Mix particularly suitable for growers who want to begin with a nutrient-rich organic growing medium rather than managing a lightly fertilised substrate from the start.

Heavily Pre-Fertilised for Strong Initial Nutrition

One of the defining characteristics of BioBizz All Mix is its substantial initial nutrient charge.

BioBizz designed All Mix to contain enough nutrient availability to support established plants for approximately the first few weeks without immediately requiring additional fertiliser.

This differs significantly from BioBizz Light Mix, which contains a much lighter initial nutrient charge and is intended for growers who want greater control over feeding from an earlier stage.

BioBizz Pre·Mix™ Organic Fertiliser

All Mix contains BioBizz Pre·Mix™, an organic dry fertiliser blend designed to support biological activity and nutrient availability within the growing medium.

Before using All Mix for the first time, BioBizz recommends activating the substrate with water. This gives the Pre·Mix and microorganisms within the substrate time to become active before planting.

How to Prepare BioBizz All Mix Before Planting

BioBizz recommends preparing All Mix approximately 36 hours before planting.

1. Place the required amount of BioBizz All Mix into the intended containers.
2. Moisten the substrate evenly with water.
3. Avoid completely saturating or waterlogging the growing medium.
4. Leave the moistened All Mix to stand for approximately 36 hours.
5. Keep the substrate in a suitably warm environment during this activation period.
6. After approximately 36 hours, the prepared substrate is ready for planting.

This preparation period allows the Pre·Mix and microorganisms within the substrate to begin becoming biologically active before roots are introduced.

Maintain a Suitable Root-Zone Temperature

Temperature plays an important role in maintaining biological activity within an organic substrate.

BioBizz recommends keeping All Mix slightly warm because excessively cool substrate conditions can slow microbial activity. Maintaining a suitable root-zone environment helps support the biological processes taking place within the growing medium.

Allow the Substrate to Breathe

Correct irrigation management is particularly important when using BioBizz All Mix.

BioBizz recommends allowing the substrate to dry appropriately between watering events rather than keeping it continuously saturated. As excess moisture leaves the growing medium, fresh air is drawn back into the substrate, helping maintain oxygen around the root zone.

A healthy wet-and-dry cycle therefore supports both root-zone aeration and the biological activity within the growing medium.

Watering BioBizz All Mix

• Water evenly throughout the root zone.
• Ensure containers provide adequate drainage.
• Avoid keeping the substrate permanently saturated.
• Allow appropriate drying between irrigation events.
• Adjust watering frequency according to plant size, container volume and environmental conditions.
• Remember that larger containers may retain moisture for longer than smaller pots.

When Should Additional Fertiliser Be Introduced?

Because BioBizz All Mix is heavily pre-fertilised, additional plant nutrition is generally not required immediately after planting established plants into fresh substrate.

BioBizz states that All Mix contains sufficient initial nutrition to sustain plant growth for approximately the first few weeks.

After this initial period, additional fertiliser can be introduced according to plant development, appearance, environmental conditions and the selected BioBizz feeding programme.

Avoid automatically applying a full-strength feeding programme immediately after transplanting into fresh All Mix, as the substrate already contains a substantial initial nutrient charge.

BioBizz All Mix vs Light Mix

Who Should Choose BioBizz All Mix?

BioBizz All Mix is particularly well suited to growers looking for a rich organic substrate with substantial nutrition already incorporated into the growing medium.

Choose All Mix when the priority is:

• A nutrient-rich organic starting substrate.
• Reduced requirement for additional fertiliser immediately after planting.
• An active organic root-zone environment.
• A growing medium suitable for established plants.
• A substrate suitable for continued use throughout vegetative growth and flowering.

Growers starting particularly sensitive seedlings, fresh cuttings or plants requiring precise control over early nutrition may prefer BioBizz Light Mix.

New 90 Litre Extra-Large Format

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

A 90 litre bag provides approximately:

• 9 x 10 litre pots
• 6 x 15 litre pots
• 4 x 20 litre pots with approximately 10 litres remaining
• 3 x 25 litre pots with approximately 15 litres remaining
• 3 x 30 litre pots

Actual requirements will vary according to pot design, filling level, root-ball displacement and natural settlement of the substrate.

How to Use BioBizz All Mix

1. Fill the required containers without excessively compressing the substrate.
2. Moisten the growing medium evenly with water.
3. Leave the substrate for approximately 36 hours before planting.
4. Maintain a suitable root-zone temperature to support microbial activity.
5. Introduce established plants into the prepared substrate.
6. Water according to plant requirements and container size.
7. Allow appropriate drying between watering events to encourage root-zone aeration.
8. Introduce additional nutrition after the initial nutrient charge begins to reduce and according to plant requirements.

Best Practice

• Moisten All Mix approximately 36 hours before first use.
• Keep the substrate at a suitable temperature to support biological activity.
• Do not excessively compact the substrate when filling containers.
• Ensure pots and containers provide effective drainage.
• Avoid continuously saturating the growing medium.
• Allow an appropriate wet-and-dry cycle between irrigation events.
• Remember that fresh All Mix already contains substantial initial nutrition.
• Introduce additional fertiliser according to plant requirements rather than automatically feeding immediately after planting.

Important Information

BioBizz All Mix is a heavily pre-fertilised organic growing substrate. Its initial nutrient content makes it significantly richer than lightly fertilised growing media. Feeding and irrigation requirements vary according to plant type, age, container size, water quality and environmental conditions. Always follow current BioBizz product and feeding guidance when introducing additional fertilisers.
