Key Benefits of Biobizz Light-Mix
- Maximum Nutrient Control: Features a low Electrical Conductivity (low EC) value, allowing you to begin feeding with liquid nutrients from day one and perfectly tailor a custom feeding program for your plants.
- Ideal for Young Plants: The lightly fertilised composition is gentle enough for germinating seeds, rooting cuttings, and transplanting sensitive young plants without the risk of fertiliser overload.
- Rapid Root Development: The superior blend of peat and perlite ensures an open, airy structure and optimal oxygen levels, driving fast and vigorous root expansion.
- Excellent Drainage: Specially formulated to ensure optimal drainage, preventing the substrate from becoming waterlogged, which is essential for healthy roots and for use with automatic irrigation systems.
- 100% Organic Base: Composed entirely of natural organic elements, maintaining a self-regulating pH system and supporting the development of beneficial microbial life.
How to Use Biobizz Light-Mix
Biobizz Light-Mix is a versatile, ready-to-use substrate suitable for all stages of plant development, but it truly excels in the initial phases.
- Preparation: Gently loosen the substrate and fill your pots, avoiding compaction. Lightly tap the pot to settle the soil evenly.
- Planting: Place your seedlings or cuttings directly into the prepared Light-Mix.
- Priming (Optional but Recommended): Water the soil to thoroughly moisten it and allow it to stand for up to 36 hours before planting. This activates the beneficial micro-activity in the substrate.
- Feeding Schedule: Because of the low nutrient charge, you should generally begin feeding immediately or after the first week of growth with a mild solution of liquid fertiliser, such as Biobizz Root-Juice followed by Biobizz Bio-Grow and Biobizz Bio-Bloom according to Biobizz's recommended schedule for Light-Mix (grow schedule available from the Downloads tab above).
- Watering: Allow the substrate to dry out slightly between waterings to encourage gas exchange and healthy root respiration.

Frequently Asked Questions
How is Light-Mix different from Biobizz All-Mix?
Light-Mix is a lightly fertilised substrate with a low EC, providing the grower with maximum control by requiring them to add liquid nutrients from the start. Biobizz All-Mix is heavily pre-fertilised, designed to feed plants for 2-4 weeks with water only.When should I start feeding liquid nutrients with Light-Mix?
While Light-Mix contains a small amount of nutrients, most growers start applying a light dose of liquid nutrients (like Biobizz Bio-Grow) after the first few days or within the first week of planting to support vigorous growth, especially for heavy-feeding plants.Can I use Light-Mix throughout the entire life cycle of my plant?
Yes, Light-Mix can be used from seed to harvest. However, since its initial fertiliser charge is low, you must diligently follow a comprehensive feeding schedule with liquid nutrients (such as the full Biobizz range) throughout the entire grow and bloom cycle to ensure maximum potential and yield.Do I still need to control the pH of my water when using Light-Mix?
While Biobizz organic products contain a self-regulating pH system that buffers the soil, Light-Mix's lower nutrient load means its buffering capacity is less pronounced than All-Mix. While many organic growers do not adjust pH, closely monitoring your input water and using an organic pH corrector like Biobizz Bio-Down can ensure nutrient uptake is fully optimised, especially if your water source is highly inconsistent.SKU: 1329Free delivery on orders over £60*
