Product information

PK 5-8 from BioTabs gives your plants an extra boost and turns them into big yielders bursting with fruits and other interesting growth products.

Bio PK 5-8 contains seaweed with added humic substances. Seaweed is very beneficial for plants helping with the growth of leaves, stems and flowers plus it also supports the development of a healthy root system. This is because it provides the plant with all the biologically active nutrients, such as enzymes, amino acids and plant hormones as well as being a source of auxins, gibberellins and cytokinins.

How to use PK 5-8 by BioTabs?

Use PK 5-8 growth booster from the second week of flowering until one week before harvest. With every watering, add 1-3 ml of PK5-8 per litre of water.

Alternatively, during flowering (weeks 3, 4, 5 & 6) give every plant 10 ml of PK 5-8 diluted in at least 1 litre of water.

It is not recommended to use liquid organic fertilisers with drip irrigation as they can block such systems.
