🌱 Pre-fertilised, ready-to-pot

Enriched with bat guano and worm castings. Clones and young plants thrive for 2 to 3 weeks with zero additional feeding.

💡 Tuned for LED grows

Light, airy structure with balanced water retention — perfectly matched to the cooler temperatures and watering rhythm of LED horticultural lamps.

🌸 Bloom booster

All-Mix is engineered for flowering: gradual nutrient release, stable pH, vigorous root systems all the way to harvest.

📦 Value 60 L bundle

Three 20 L bags shipped in one parcel for an unbeatable price per litre (~€0.93). Enough to repot a full grow tent in one go.

How many 11 L pots can I fill with 60 L?

Around 5 to 6 pots of 11 L, or 8 to 9 pots of 7 L. Plenty for an 80×80 cm tent running 4 plants in 11 L containers.

Do I need to add fertiliser when I pot up?

No. All-Mix is already loaded. Hold off on nutrients for the first 2 to 3 weeks, then watch leaf colour to decide when to start feeding.

Is All-Mix suitable for LED culture?

Yes — that's one of its strengths. Its light, well-drained structure handles the longer watering cycles typical of LED-lit indoor gardens.

🌱 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.

Is Biobizz All-Mix suitable for LED grows?

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.
