Bio PK 5-8

The mighty Bio PK 5-8 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 PK5-8 per litre of water.
during flowering, weeks 3, 4, 5 & 6, feed 10 ml of Bio PK 5-8 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 5-8 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.
