🌸 Denser flowering
The targeted supply of phosphorus and potassium supports flower bud formation and promotes more numerous, more compact and heavier flowers by harvest time.
🌿 100% organic
Made from algae, vitamins and natural phytohormones, this booster protects the microbial life of the soil and fits a true organic growing approach, with no synthetic chemical residues.
⚗️ Active phytohormones
The phytohormones and vitamins in the formula naturally stimulate the plant's metabolism during the key flowering phase, helping it express its full genetic potential.
💧 Easy to dose
Simply dilute 10 ml of BioTabs PK 5-8 in 1 litre of watering water. Regular use from week 3 to week 6 is enough to support the entire bloom.
When should I use the BioTabs PK 5-8 flowering booster?
Apply it during the flowering phase, ideally from week 3 to week 6. Dilute 10 ml in 1 litre of water and feed your plants during this period to support flower formation and fattening.
Is this booster really 100% organic?
Yes. BioTabs is a Dutch brand specialised in organic fertilisation. The PK 5-8 is made from algae, vitamins and natural phytohormones, with no synthetic chemical fertilisers, for a healthy crop that respects the soil.
Is it suitable for both indoor and outdoor growing?
Absolutely. The BioTabs flowering booster works just as well for indoor growing (under horticultural LED, in a grow tent) as outdoors, on plants grown in soil. It is an ideal complement to an organic feeding routine.
Paired with a high-performance horticultural LED, the BioTabs PK 5-8 flowering booster helps you get the best out of every cycle: denser flowers, preserved aromas and optimised yields, all while respecting living soil.
