Experience the power of a living soil with All-Mix from Biobizz, the heavily pre-fertilised, 100% organic substrate designed to mimic rich, natural outdoor soil. This premium potting mix is the perfect foundation for established plants, providing a complete micro-active ecosystem that requires little external feeding for the first few weeks. A careful blend of peat moss, perlite, worm castings, and the proprietary Pre-Mix ensures optimal aeration, superior water retention, and a self-regulating system for consistent, vibrant growth from vegetative to flowering stages.
Key Benefits of Using Biobizz All-Mix
- Heavily Pre-Fertilised: Contains enough readily available, natural organic nutrients to sustain robust plant development for the initial 2-4 weeks, reducing the need for early liquid feeding.
- 100% Certified Organic: Fully certified organic, allowing you to cultivate in harmony with nature and ensuring a clean, flavourful final product.
- Promotes Active Micro-Life: Enriched with Pre-Mix to foster a thriving microbial ecosystem in the root zone, which buffers pH and enhances the natural nutrient cycling for superior uptake.
- Optimal Structure and Aeration: The blend of high-quality peats and 30% perlite creates a light, airy structure, ensuring excellent drainage and high oxygen levels crucial for healthy, vigorous root growth.
- Self-Regulating pH: The organic elements naturally buffer the substrate's pH, keeping it in the ideal range without the need for synthetic pH adjusters, making feeding simpler.
How to Use Biobizz All-Mix
Biobizz All-Mix is a potent, ready-to-use potting mix best suited for established plants.
- Preparation (The "Warm Bed"): When using All-Mix for the first time, moisten the substrate thoroughly with plain water and allow it to stand in a warm place for 36 hours. This activates the Pre-Mix fertiliser and beneficial microorganisms before your plant is introduced.
- Transplanting: Gently fill your container with the loosened soil. Do not compress the substrate; lightly tap the pot to settle the mix and maintain its airy structure. Transplant your established plant (cuttings and seedlings are best started in Biobizz Light-Mix).
- Watering: Allow the soil to dry out between waterings. As the soil dries, fresh air (oxygen) is drawn into the root zone. A good rule of thumb is to re-water when the pot feels approximately half its saturated weight.
- Feeding Schedule: Begin feeding with liquid nutrients like Biobizz Bio-Grow and Biobizz Bio-Bloom after the first 2-4 weeks. Continue to use powerful organic supplements like Biobizz Top-Max and Biobizz Root-Juice throughout the cycle for premium yields.

Frequently Asked Questions
Is Biobizz All-Mix too strong for seedlings or cuttings?
Yes. Due to its heavily pre-fertilised nature and high nutrient concentration (EC value often cited around 2.4), All-Mix can be too potent and cause nutrient burn for young plants, clones, or seedlings. It is highly recommended to start with a less fertilised substrate, such as Biobizz Light-Mix, before transplanting into All-Mix once the plant is established.Do I need to adjust the pH of my water when using All-Mix?
Generally, no. Biobizz products contain complex organic elements rather than mineral salts. These elements create a self-regulating system in the soil that naturally buffers the pH to the optimal range (around 6.2-6.5), eliminating the need for synthetic pH Up or pH Down solutions which can harm the beneficial microbial life.How long can I grow in All-Mix before I need to add liquid nutrients?
Biobizz All-Mix is designed to sustain lush growth for approximately 2-4 weeks with plain water alone. This duration depends on the pot size and the plant’s size and vigour. Once the plant starts demanding more nutrients, follow the official Biobizz feeding chart (found in the Downloads tab above) and begin administering the liquid feed.Can I reuse Biobizz All-Mix for another grow cycle?
Yes, Biobizz All-Mix can often be reused, although it requires some effort. To recycle it, remove all old root matter and discard the top surface layer of soil. Rejuvenate the mix by adding fresh Worm·Humus (around 10%) and the proprietary Pre-Mix (around 5%) before moistening and allowing it to reactivate for at least a week.SKU: 1345 Free delivery on orders over £60*
