Light-Mix Substrate 20 Liters Biobizz is an organic soil with mild fertilization that allows total control of the nutrition plan in indoor cultivation. With an airy structure, good moisture retention, and uniform drainage, it enhances rooting and provides a quick response to watering in substrates for cannabis. Available at Hydroponics Blanes, online grow shop with discreet shipping.

Light-Mix Substrate 20 Liters Biobizz is formulated for those who want to decide on liquid fertilization from the very first weeks.
The organic blend from Biobizz combines selected peat fractions with extra aeration and a very light pre-fertilization, so the medium acts as a nutritional “canvas”: the plant receives just enough to start and each grower adjusts EC and pH according to phase and genetics. The porous matrix promotes gas exchange in the rhizosphere, preventing compaction and waterlogging.
The water/air balance allows for frequent watering without root suffocation and even drying between waterings, an ideal condition for automated drip or manual pulse watering.
Indicative values for new material: EC ≈ 1.2 and pH ≈ 6.2, ranges designed for stable management of compatible organic or mineral fertilization.
The 20 L format is convenient for transplants, small grow tents, and pilot mixes; it also works very well with Biobizz range additives (Bio·Grow, Bio·Bloom, Top·Max, Alg·A·Mic, Bio·Heaven, Acti·Vera), allowing you to scale productivity without losing control.
In indoor growing, the spongy structure keeps pores active and redistributes water by capillarity, achieving fine roots and rapid colonization of the container. Thanks to the gentle initial nutrition, the plant responds very directly to each fertilization and photoperiod adjustment, both with LED and HPS. Regular drainage and constant aeration provide stability in grow tents with high watering frequency.
It serves as a main medium for low fertilization that allows you to build a custom liquid plan: ideal for freshly rooted cuttings, seedlings, and growth phases where fine control of nutrient input is sought. It is also excellent as a base for mixing with perlite or coco if faster drying is desired, maintaining optimal conditions in substrates for cannabis.
Organic blend with selected peats, added aeration, and balanced water reserve. Outstanding properties: EC ≈ 1.2, pH ≈ 6.2, homogeneous texture, uniform drainage, and sufficient moisture retention to buffer peaks between waterings. The low nutrient load reduces the risk of early overfertilization and allows a clear reading of plant behavior.
Initial conditioning: slightly moisten the substrate before transplanting to activate the microbiota; do not compact when filling pots, just level with your palm.
Transplant: choose containers with good drainage; optionally, place 2–3 cm of clay pebbles at the base to drain excess water.
Watering and fertilization: start with low EC solutions; from the second week, gradually increase inputs with Bio·Grow in vegetative and Bio·Bloom + Top·Max in flowering. Maintain pH 6.0–6.3 for organic programs.
Frequency: allow the substrate to lose some moisture between waterings to promote oxygen intake; in warm climates, Light·Mix retention helps space out watering.
Compatibilities: combines excellently with perlite (10–30 %) or fine coco to customize drying and aeration; suitable for manual or drip watering.
