BioTabs PK Booster Compost Tea is a highly concentrated organic compost tea formulated to deliver a powerful combination of phosphorus and potassium alongside beneficial microorganisms. Designed to support plant development and strengthen natural resistance, it works by enriching the growing medium with active biology that improves nutrient availability and plant health. Plants respond rapidly after application, displaying improved structure, enhanced vigour, and greater resilience to environmental stress and pathogen pressure. The active microorganisms also help optimise the growing medium over time, allowing it to be reused without the need for additional enrichment products.
