🌱 Pre-fertilised: instant start
The All-Mix blend already contains worm castings and bat guano. Young plants enjoy two to three weeks of available nutrients before any feeding is needed — ideal for the vegetative phase under LED lighting.
💧 Controlled drainage and aeration
Perlite and coconut fibre prevent waterlogging. Roots breathe freely, water flows without stagnation: perfect conditions for the modern LED bulbs and panels that demand a responsive substrate.
🌿 100% organic-friendly
All-Mix is designed to pair with Biobizz organic nutrients and other bio-grow ranges. No chemical additives — beneficial microflora activates from the first watering.
📦 40 L pack shipped as a parcel
Two 20 L bags wrapped in reinforced packaging — no pallet logistics required. A smart format for 80×80 or 100×100 grow tents lit by a BloomLED horticultural panel.
Should I feed nutrients from the very first watering?
No. All-Mix is pre-fertilised for roughly two to three weeks. Water with clear water (pH 6.0–6.5) and observe the plants: start feeding when you see the first signs of appetite (slower growth, slight pale tones on the lower leaves).
How many pots will 40 L of soil fill?As a guideline: roughly 4 pots of 11 L, 7 pots of 5.5 L, or about ten pots of 3.8 L. For an 80×80 cm tent with 4 plants in 11 L pots, this pack typically covers one full cycle.
Is All-Mix suitable under LED horticultural lamps?Yes — it is particularly well suited to full-spectrum LEDs. Its moderate water retention and aeration keep root activity aligned with the high light intensity delivered by modern LED panels.
What is the difference with Biobizz Light-Mix?Light-Mix is barely fertilised (ideal for clones and young plants fed from the start). All-Mix is pre-fertilised and suited to well-established plants or direct transplants into final pots.
The winning combo: Biobizz All-Mix for substrate stability, a BloomLED LED panel for light, and a Biobizz organic feed line to amplify — a trio chosen by our team for its reproducible indoor-grow results.
