Biotabs Bio PK 5-8 1l

Biotabs Bio PK 5-8 in the 1 litre format is the standard-volume organic bloom booster (NPK 2-5-8) for growers managing multiple plants per cycle or requiring season-long PK supplementation without reordering. The formulation combines phosphorus and potassium with seaweed extract, vitamins A, B1, B2, B3, B12, auxins, phytohormones, calcium and humic acid for comprehensive organic bloom stimulation. Dose at 1 to 3 ml per litre at every irrigation during flowering, or apply 10 ml per plant in weeks 3 through 6. One litre yields 333 to 1000 litres of bloom solution — sufficient for a complete flowering programme across dozens of plants. The per-litre cost is lower than the half-litre format. Order now.

Biotabs Bio PK 5-8 one litre — professional-volume organic bloom booster with full bioactive complex

Scaling organic bloom supplementation requires a product that delivers consistent performance across large plant counts without the operational overhead of frequent purchasing. Biotabs Bio PK 5-8 in the 1 litre format meets this requirement directly — producing up to 1000 litres of bloom solution from a single bottle while maintaining the full NPK 2-5-8 formulation plus seaweed, vitamins, phytohormones, calcium and humic acid. For growers who have validated this product's impact on flowering performance, this is the operationally efficient format within the Biotabs line.

The metabolic case for PK supplementation during flowering

During the flowering transition, plant metabolism undergoes a fundamental shift. Phosphorus demand increases as ATP turnover accelerates to support the energy-intensive processes of floral tissue synthesis and reproductive development. Potassium requirements rise in parallel, driven by its roles in stomatal regulation, phloem sugar loading and osmotic stress management. Bio PK 5-8 delivers both macronutrients in organically bound forms that release through biological mineralisation, complemented by a bioactive compound matrix that supports the enzymatic machinery driving these metabolic processes.

Bioactive compound profile

The competitive advantage of Bio PK 5-8 over mineral PK boosters lies in its multi-pathway approach to bloom stimulation:

  • Seaweed-derived auxins and phytohormones — regulate meristematic activity and floral organ differentiation at the hormonal level
  • Vitamin complex (A, B1, B2, B3, B12) — cofactors in respiratory chain enzymes and secondary metabolite biosynthesis pathways that determine aroma and flavour profiles
  • Calcium (2.5%) — structural component preventing blossom end rot and maintaining tissue rigidity under high metabolic load
  • Molasses and humic acid — sustain rhizosphere microbial activity during the critical flowering period when biological nutrient cycling must operate at peak efficiency

Dosing and system integration

Apply from flowering week two through one week pre-harvest. Continuous method: 1-3 ml/L at every irrigation. Pulse method: 10 ml per plant in weeks 3-6. Not suitable for drip irrigation. Integrate with Orcatrex base nutrition and Bactrex for continued root zone protection during the intensive flowering phase.

Biotabs Bio PK 5-8 is certified 100% organic. Order from Plant&Flower for fast delivery across Belgium.

How many litres of bloom solution does 1 litre of Bio PK 5-8 produce?

At the minimum rate of 1 ml per litre, one litre produces 1000 litres of bloom solution. At 3 ml per litre, the yield is approximately 333 litres.

What is the difference between continuous and pulse dosing methods?

The continuous method (1-3 ml/L at every watering) provides steady PK supplementation throughout the entire flowering period. The pulse method (10 ml per plant in weeks 3-6) delivers concentrated inputs at peak demand periods. Both approaches are effective, and the choice depends on growing style and operational preference.

Can Bio PK 5-8 be mixed with Orcatrex in the same solution?

Bio PK 5-8 and Orcatrex are designed for combined use within the Biotabs system. Both can be added to the same irrigation solution. Orcatrex provides base nutrition (NPK 5-1-5) while Bio PK 5-8 supplies the additional phosphorus and potassium required during flowering.

What vitamins does Biotabs Bio PK 5-8 contain?

Bio PK 5-8 contains vitamins A, B1, B2, B3 and B12. These vitamins function as enzymatic cofactors in metabolic pathways that peak during the energy-intensive flowering phase, supporting both primary metabolism and secondary metabolite production.
