ORGANIC SUBSTRATE

Biobizz Light-Mix 20L 2-Pack: 40 litres of premium soil for indoor growing

Biobizz Light-Mix is the go-to substrate for serious indoor growers. This 2-pack gives you 40 litres of an airy, free-draining and lightly pre-fertilized soil — exactly what cuttings, seedlings and young plants need under a horticultural LED lamp. A 100% organic blend of light peat, perlite and organic fertilizers, formulated for intensive grow tent cultivation where root aeration and fast drainage make all the difference.

🌱 Perfect for indoor starts

The Light-Mix's gentle pre-fertilization carries cuttings and young plants without burning roots. The most versatile base to kick off a grow under LED — especially in a mini grow tent or propagator.

💨 Optimised airflow and drainage

Built-in perlite prevents compaction and boosts root oxygenation — critical under a horticultural LED lamp where substrate moisture must stay in control to avoid root rot and disease.

🍃 100% certified organic

Biobizz Light-Mix complies with organic farming standards. No synthetic chemistry: you grow clean, for yourself and for your plants.

📦 2 bags shipped by courier

40 L packaged as 2 × 20 L bags, delivered straight to your door. Easier to handle than a single big bag, more affordable than buying single units — the right amount for a full 60×60 or 80×80 grow cycle.

How much Light-Mix do I need for a 60×60 grow?

40 L is enough to fill 4 to 6 pots of 7 L (the classic size for a 60×60). With 11 L pots, plan on 3 to 4 pots — the 2-pack is sized for a full grow cycle.

Do I need to add fertilizer with Light-Mix?

The pre-fertilization lasts 2 to 3 weeks after potting. Beyond that, you'll need to add a grow then bloom nutrient — the Biobizz Bio·Grow / Bio·Bloom range is the most consistent fit, but T.A. Pro Organic or BioCanna also work very well.

Can this soil be used for cuttings?

Yes — Light-Mix is one of the best substrates for soil cuttings thanks to its airy structure and very light pre-fertilization. Pair it with a propagation LED bar like SpectraLINE for an optimal strike rate.

Selected by the BloomLED team among the most-used substrates by our indoor growers — a classic, proven across thousands of grow cycles under LED.
