A uniquely powerful PK booster, Buddhas Tree PK 9/18 produces blooms and fruits of exceptional weight and quality. Designed for use from Week 3 of bloom stage onwards, PK 9/18 gets straight to work breaking down enzymes in the root zone. This groundwork is essential for a proper boost as it facilitates enhanced uptake of the booster’s phosphorus and potassium content.

PK 9/18 takes phosphorous and potassium content to unparalleled heights, being as it is the only UK-available PK booster with a 9/18 ratio. This considerable feat of engineering helps produce dizzyingly dense fruits and flowers imbued with a sublime richness of flavour. Phosphorus does the heavy lifting, building out cell wall structure, maximising root expansion, and stimulating enzymes for enhanced development. Meanwhile potassium intensifies the quality of your blooms and swells their scale by boosting the production of proteins and carbohydrates.

Unusually for a PK booster, 9/18 is intended for regular, extended use but its extremely high concentration means that it remains a very cost-effective means of producing vastly improved harvests. For maximum usability Buddhas Tree have formulated the additive to run in any cultivation system, with all growing mediums.
