Light-Mix 50 L Biobizz Substrate is an organic soil with light fertilization designed for those who want total control of the nutrient plan in indoor cultivation. Airy mix, balanced moisture retention and even drainage for active roots within substrates for cannabis. Available at Hydroponics Blanes, online grow shop with discreet shipping and service from a trusted Grow Shop.

Substrate Light-Mix 50 L Biobizz is formulated with selected fractions of peat moss and perlite that provide a spongy structure and stable porosity. Thanks to a light initial fertilization, the medium acts as a “nutritional canvas” to define each watering precisely, adjusting EC and pH according to stage and genetics.
The porous matrix improves gas exchange in the rhizosphere, reduces compaction and promotes even drying between waterings, an ideal condition for automated drip or pulse irrigation.
Indicative indicators of the new material: EC ≈ 1.2 and pH ≈ 6.2, ranges designed for stable management with compatible organic or mineral programs. The 50 L bag is suitable for multiple transplants and makes it easy to standardize recipes between grow tents.
Combined with the Biobizz line (Bio·Grow, Bio·Bloom, Top·Max, Bio·Heaven, Alg·A·Mic, Acti·Vera), it allows you to scale productivity while maintaining fine control of fertilization.
All this with specialized technical support from Hydroponics Blanes and logistics with discreet shipping throughout Spain.
In indoor growing, the structure of Light-Mix maintains active macropores and redistributes water by capillarity, boosting fine roots and rapid colonization of the container. Drainage is regular, pH/EC readings are consistent and the response to each fertilization adjustment is clearly perceived under LED or HPS. The 50 L format makes it easy to prepare batches for several pots and maintain consistency between runs.
It serves as a main medium for low fertilization for seedlings, rooted cuttings and growth phases where it is important to modulate nutrients step by step. It also works as a base to customize mixes with additional perlite or fine coco when faster drying is desired. Among substrates for cannabis, it provides air/water balance and a very predictable platform for liquid plans.
Indicative composition: peat moss and perlite, with gentle pre-fertilization. Key properties: EC ≈ 1.2, pH ≈ 6.2, great aeration, good moisture retention and uniform drainage. The homogeneous texture reduces compaction, facilitates clean transplants and offers a very wide window of nutritional management for the entire cycle.
Initial conditioning: slightly moisten before transplanting to activate microbiota; avoid compacting when filling pots, gentle pats are enough to settle.
Containers and drainage: choose pots with effective holes; 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 with Biobizz bases and additives (e.g., Bio·Grow in vegetative; Bio·Bloom + Top·Max in flowering). Maintain pH 6.0–6.3 in organic programs.
Frequency: allow slight moisture loss between waterings to promote oxygen intake; adjust frequency/volume according to climate, pot size and phenological stage.
Customization: add 10–30 % perlite if faster drying is desired; mix with fine coco to increase aeration in long cycles.
The 50 L bag offers a very competitive volume/performance ratio for indoor growing projects seeking nutritional control and consistency. Check availability and promotions at Hydroponics Blanes, with specialized technical advice and discreet shipping from a trusted Grow Shop.
