Enriched with bat guano and worm castings. Clones and young plants thrive for 2 to 3 weeks with zero additional feeding.
Light, airy structure with balanced water retention — perfectly matched to the cooler temperatures and watering rhythm of LED horticultural lamps.
All-Mix is engineered for flowering: gradual nutrient release, stable pH, vigorous root systems all the way to harvest.
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.
