PK Booster Compost Tea

BioTabs PK Booster Compost Tea is a concentrated organic bloom booster that functions as a compost tea base — it's steeped and applied as a living fermented input rather than a standard liquid nutrient. The formula contains extremely concentrated organic compost, bat guano, kelp, phosphorus-releasing bacteria, potassium-mobilizing bacteria, and specially selected organic ingredients.

The phosphorus-releasing and potassium-mobilizing bacterial strains are the standout feature: these soil microorganisms solubilize bound phosphorus and potassium compounds already present in the growing medium, making them available to plant roots that couldn't access them otherwise. The result is improved phosphorus and potassium availability throughout bloom without necessarily increasing the amount added.

Apply 3 times during flowering — in weeks 3, 4, and 5 — by mixing with aerated water (an aeration pump is required, not included). The aeration step activates the microbial component and ensures the tea reaches plants in peak biological condition. Used within BioTabs' organic system to complement their slow-release tablet program, it delivers the biological bloom support that amplifies the tablets' effect.
