🌱 Pre-fertilised, ready to plant
The built-in organic charge of worm castings and microbial Pre-Mix feeds your plants for 4 to 6 weeks without any additional fertiliser. You save time, simplify your grow routine and eliminate dosing mistakes that often trip up beginner indoor growers under LED.
🦠 Living microbial ecosystem
Biobizz Pre-Mix carries a consortium of bacteria and mycorrhizal fungi that colonise the root zone, boost nutrient uptake and strengthen the plant's natural resistance to drought stress or root pathogens — a real boost in productivity.
💧 Optimum drainage and aeration
30% perlite keeps the substrate light and airy, preventing compaction and root suffocation even in large pots or with automated watering systems. Roots breathe freely and explore the entire growing medium for healthier indoor growth.
✅ OMRI and SKAL certified
All-Mix is listed by OMRI (USA) and SKAL (Netherlands), two leading organic certifications. No mineral fertilisers, no chemical additives — you grow indoor in full compliance with international organic farming standards.
📦 Five-bag bundle = smart value
The 5-pack secures a full indoor growing season or equips several 11 to 25 litre pots in one go. You cut down on shipping, avoid stockouts and benefit from a homogenous batch — ideal for reproducible, predictable results under LED.
With 100 litres you can fill roughly 9 pots of 11L, 5 to 6 pots of 18L, or 4 pots of 25L. For a typical 80×80 cm LED indoor grow tent (4 plants in 18L pots) this bundle covers the full cycle plus a comfortable margin for repots.
Do I need to add fertiliser with Biobizz All-Mix?No — not during the first 4 to 6 weeks; the substrate is pre-fertilised. After that you can top up with the Biobizz liquid range (Bio-Grow, Bio-Bloom) to sustain a strong bloom. The natural pH of 6.2-6.6 ensures excellent organic nutrient assimilation.
Is All-Mix suitable for LED indoor growing?Yes, it's the recommended use. Under full-spectrum LED, plants quickly assimilate the organic nutrients from the substrate. The high perlite content prevents the excessive water retention often seen indoors, where evapotranspiration is lower than outdoors.
How should I store the unused bags?Keep the bags sealed or resealed in a dry place, away from direct sunlight, at moderate temperature (10-25°C). Stored properly, a bag retains its full microbial activity for 12 to 18 months. Avoid damp cellars or frost-prone garages.
The BloomLED pick for serious indoor growers — 100L of premium organic soil delivered as a smart bundle, ready to kick off your LED growing season with zero compromise on quality.

🍃 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.
