| Specification | Value |
|---|---|
| Pack contents | 2 bags × 20 L (40 L total) |
| Brand | Biobizz (Netherlands) |
| Mix type | All-Mix — pre-fertilised ready-to-use soil |
| Composition | Brown peat, coconut fibre, perlite, worm castings, bat guano |
| pH | ≈ 6.2 |
| EC (conductivity) | ≈ 1.8 mS/cm |
| Recommended use | Indoor growing under full-spectrum LED horticultural lamps |
| Packaging | Well-protected parcel — no pallet required |
🌱 Pre-fertilised: instant start
The All-Mix blend already contains worm castings and bat guano. Young plants enjoy two to three weeks of available nutrients before any feeding is needed — ideal for the vegetative phase under LED lighting.
💧 Controlled drainage and aeration
Perlite and coconut fibre prevent waterlogging. Roots breathe freely, water flows without stagnation: perfect conditions for the modern LED bulbs and panels that demand a responsive substrate.
🌿 100% organic-friendly
All-Mix is designed to pair with Biobizz organic nutrients and other bio-grow ranges. No chemical additives — beneficial microflora activates from the first watering.
📦 40 L pack shipped as a parcel
Two 20 L bags wrapped in reinforced packaging — no pallet logistics required. A smart format for 80×80 or 100×100 grow tents lit by a BloomLED horticultural panel.
No. All-Mix is pre-fertilised for roughly two to three weeks. Water with clear water (pH 6.0–6.5) and observe the plants: start feeding when you see the first signs of appetite (slower growth, slight pale tones on the lower leaves).
How many pots will 40 L of soil fill?As a guideline: roughly 4 pots of 11 L, 7 pots of 5.5 L, or about ten pots of 3.8 L. For an 80×80 cm tent with 4 plants in 11 L pots, this pack typically covers one full cycle.
Is All-Mix suitable under LED horticultural lamps?Yes — it is particularly well suited to full-spectrum LEDs. Its moderate water retention and aeration keep root activity aligned with the high light intensity delivered by modern LED panels.
What is the difference with Biobizz Light-Mix?Light-Mix is barely fertilised (ideal for clones and young plants fed from the start). All-Mix is pre-fertilised and suited to well-established plants or direct transplants into final pots.
The winning combo: Biobizz All-Mix for substrate stability, a BloomLED LED panel for light, and a Biobizz organic feed line to amplify — a trio chosen by our team for its reproducible indoor-grow results.

🌱 Pre-fertilised, ready to use
The built-in organic nutrient pre-mix feeds your plants for 2 to 3 weeks after transplant — no need to start fertilising right away.
💧 Optimised drainage & aeration
Perlite ensures excellent drainage and oxygen at the root zone — ideal for intensive LED grows that demand a living, well-aerated medium.
🍃 100% organic, Biobizz certified
Natural composition with no chemical fertilisers. Compatible with the full Biobizz nutrient range and most organic indoor LED grow protocols.
Absolutely. Horticultural LEDs run cool, which lowers evaporation and favours a living substrate like All-Mix. Full-spectrum LED + pre-fertilised organic soil is the winning combo of expert growshops.
How long before I need to add nutrients?Around 2 to 3 weeks after potting up. From there, top up with the Biobizz liquid range (Bio-Grow then Bio-Bloom) or any organic feed matched to your cycle.
The BloomLED pick: for indoor grows under full-spectrum LED, All-Mix offers the best balance between simplicity, performance and respect for living soil. Designed in France, selected by growing enthusiasts.
