BioTabs Bio PK 5-8

BioTabs Bio PK 5-8 – Organic liquid fertiliser NPK: 2–5–8 + seaweed, vitamins, auxins and other phytohormones.

The mighty Bio PK Top-Booster from BioTabs yields large & fragrant BUDS.


From the second week of flowering until one week before harvest, with every watering, add 1-3 ml of BIO PK per litre of water.
during flowering, weeks 3, 4, 5 & 6, feed 10 ml of Bio PK to each plant, diluted in at least 1 litre of water.

We do not recommend the use of liquid organic fertilisers with drip irrigation as they can block such systems.

BIO PK contains BioTabs’ flower boosting formula combined with trace elements, phosphorus, potassium, calcium (2,5%), molasses, humic acid and vitamins A, B1, B2, B3, B12 to ensure your plants flower to their maximum potential.
