Monkey PK 9/18 turns the key on flowering, taps the gas, and keeps high-grade elements flowing to your plants. This potassium and phosphorous-rich supplement stimulates energy transfer, triggers fruit production, and creates swathes of flower sites when used to instigate the bloom. Continue to use Monkey PK 9/18 through the highly demanding mid-bloom phase and it will easily satisfy the needs of your crops, setting you up for phenomenal yields.

Formulated by U.K. growers with many decades of experience between them, PK 9/18 is the result of extensive testing in the search for an optimised PK concentration. The 14% phosphorous goes to work on energy production and transfer, improves cell structure, and increases flower weight immeasurably. Stimulating carbohydrate metabolism and sugar production, the 15% potassium content kicks up the overall quality and flavour of the crop.
