🌱 BioBizz All Mix 50L — Guide and Product Information
Product overview
BioBizz All Mix 50L is a rich, heavily pre-fertilised soil designed to provide plants with a biologically active growing environment from the moment you pot up. Created to mimic a fertile outdoor soil structure, All Mix contains a full micro-active ecosystem and enough nutrient charge to support healthy early growth for the first couple of weeks without the immediate need for additional feed.
As part of our Growing Media range and our dedicated Soil category, this substrate is well suited to growers looking for a ready-to-use organic potting mix that simplifies early stage plant care.
Why choose BioBizz All Mix?
All Mix is designed for growers who want a strong start without having to build a soil blend from scratch. Its pre-fertilised composition helps reduce the need for extra nutrients in the earliest stage after potting, while the active microbial life supports a healthy root zone and better soil structure.
- ✔ Ready-to-use organic soil blend
- ✔ Rich nutrient charge for early plant development
- ✔ Encourages a healthy microbial root environment
- ✔ Suitable for growers who prefer soil-based cultivation
- ✔ Supports strong establishment after transplanting
Features and practical growing benefits
BioBizz states that All Mix contains natural organic elements rather than synthetic mineral salts. This gives the substrate a naturally high EC, while the organic composition supports self-regulating pH behaviour within the root zone. In practical terms, this makes it a useful choice for growers who want a living soil feel with less reliance on immediate bottled feeding.
If you are comparing soil and coco options, you may also want to look at PLAGRON GROW MIX 50L or Canna Terra Professional Soil Mix 50L Bag for alternative soil-based growing media.
Suitable applications
BioBizz All Mix 50L is suitable for general potting and transplanting where a nutrient-rich organic soil is preferred. It works well for growers wanting a straightforward growing medium for containers, pots and indoor or greenhouse cultivation where a fertile, breathable root zone is important.
For propagation before transplanting into a larger container of All Mix, products such as the Root Riot 24 Tray can help establish young plants before they are moved into final pots.
Related growing advice and media choices
Successful soil growing also depends on the wider environment. Good airflow and correct watering practices are especially important with rich organic media. For more advice, read our guide to the importance of proper ventilation in a grow tent.
If you prefer lighter or more aerated media, you may also consider blends using PLANT!T Perlite 10L alongside your potting setup where appropriate.

Setup and Usage Tips
When using BioBizz All Mix for the first time, moisten the soil with water and allow it to stand for around 36 hours before planting. This helps activate the pre-mix fertiliser and microorganisms already present in the substrate.
Keep the soil slightly warm where possible, as colder conditions can slow microbial activity. It is also good practice to allow the medium to dry back between waterings rather than keeping it constantly saturated. As the soil dries slightly, fresh air can move into the root zone, helping the substrate stay breathable.
Because All Mix is a rich, pre-fertilised soil, avoid overfeeding at the beginning. Monitor plant response first before introducing additional nutrients.
FAQ
What is BioBizz All Mix used for?
BioBizz All Mix is used as a soil growing medium for potting plants in containers and creating a biologically active root environment with built-in early nutrition.
Is BioBizz All Mix pre-fertilised?
Yes. It is described as a heavily pre-fertilised substrate and is designed to provide enough nutrient support for the first couple of weeks without needing extra fertiliser straight away.
Do I need to prepare All Mix before planting?
Yes. BioBizz recommends moistening the soil with water and leaving it to stand for around 36 hours before use so the active fertiliser and microorganisms can begin working.
How often should I water plants in All Mix?
Watering will depend on plant size, pot size and environment, but it is best not to keep the soil constantly wet. Allowing some dry-back between waterings helps improve airflow within the substrate.
Is All Mix suitable for beginners?
It can be a good choice for growers who want a ready-to-use organic soil, but because it is nutrient-rich, care should be taken not to overwater or overfeed during the early stages.
Can I use extra nutrients with BioBizz All Mix?
Yes, but additional feeding is usually introduced only after the initial nutrient charge begins to reduce. It is best to assess plant needs first rather than feeding immediately.
