🌸 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.
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.
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.
