Pack description
Pack x4 Biobizz All-Mix 80L: the all-in-one organic substrate for indoor LED growing
The x4 pack of Biobizz All-Mix 20L bags gives you 80 litres of pre-fertilised organic substrate — the ideal format to run a complete growing cycle under a horticultural LED lamp. Carefully selected by BloomLED, your French indoor cultivation expert with 10+ years of experience, this premium soil is loaded with natural biostimulants, an airy structure and nutrient power that lasts up to 6 weeks without additional fertiliser.
| Specification | Value |
|---|---|
| Brand | Biobizz (Netherlands) |
| Format | 4 bags × 20L = 80 litres |
| Type | Pre-fertilised organic substrate |
| Composition | Sphagnum peat, coco fibre, perlite, worm castings, bat guano |
| pH | 6.2 — 6.8 (ideal indoor) |
| Nutrient autonomy | 4 to 6 weeks without fertiliser |
🌱 Ready-to-use pre-fertilised substrate
All-Mix comes pre-loaded with nutrients (worm castings, bat guano, perlite). Your plants kick off in top shape right after transplant, with zero fertiliser needed for the first 4 to 6 weeks.
💧 Optimal water retention
The peat + coco fibre + perlite blend strikes the perfect balance between moisture retention and drainage. Your roots breathe and drink at the right pace — no more over- or under-watering.
🔬 Active microbial life
Rich in mycorrhizae, trichoderma and beneficial bacteria, this substrate builds a living root ecosystem that boosts nutrient uptake and disease resistance.
📦 Cost-effective x4 pack
80 litres in a single purchase: enough to fill 8 to 10 pots of 11L or cover a full cycle in a 120×120 grow tent under LED. Save up to 15% versus buying single bags.
🌍 Certified 100% organic
Biobizz is one of the few manufacturers fully certified organic across its entire process. No chemical fertilisers, no synthetic pesticides — you harvest a pure final product with intense natural aromas.
With 80 litres of All-Mix, you can fill roughly 8 pots of 11L, 5 pots of 15L or 4 pots of 20L. It's ideal for a 120×120 cm tent under a BloomLED 300W LED lamp, or for 2 complete cycles in an 80×80 tent.
Do I need to add fertiliser with this soil?Not before 4 to 6 weeks after transplanting. All-Mix is pre-fertilised with worm castings and guano. Once flowering starts under LED, supplement with the Biobizz Bio·Bloom range or any compatible organic feed.
What pH and EC should I water with on All-Mix?All-Mix natural pH sits between 6.2 and 6.8. Water with pH 6.3 to 6.5 and EC 0.4 to 1.8 depending on stage (higher during flowering). Water that is too acidic or too hard blocks nutrient absorption.
How long can I store the soil?Stored dry, away from frost and direct heat, All-Mix bags keep their quality for 12 to 18 months. Once opened, ideally use within 3 months to preserve the microbial life.
The Biobizz All-Mix x4 pack is our best-selling format at BloomLED: 80L of premium substrate, shipped in a secure box, at the best value on the French market.

🌱 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.
