PhosK is a high-performance PK booster formulated to drive explosive flower development through elevated levels of phosphorus and potassium. As one of the most concentrated PK formulas on the market, PhosK delivers superior strength per millilitre compared to competitor products that are often two to three times the price while offering significantly lower NPK values.
Designed for use during the critical bloom phase, PhosK supports rapid bud formation, increased flower density, and improved energy transfer within the plant. By delivering targeted, ultra-concentrated PK nutrition when plants demand it most, PhosK helps maximise yield potential while supporting strong, healthy floral structure—without the need for excessive dosing or costly additives.
PhosK is a concentrated bloom formula engineered to deliver elevated levels of phosphorus (P) and potassium (K)—two essential macronutrients that directly influence bud formation, floral density, and overall flower quality. These nutrients play a critical role in energy transfer, sugar movement, and cell expansion, allowing plants to build bigger, heavier, and more resin-rich blooms during the demanding flowering phase.
This improved uptake translates to enhanced metabolic activity, stronger internal nutrient transport, and noticeably more vigorous flower development.
By supplying a powerful nutrient boost exactly when plants need it most, PK MAX promotes:
Throughout the flowering cycle, growers can expect stronger plants, more resilient blooms, and significantly elevated yield potential. PhosK works seamlessly alongside your feeding program to maximise genetic potential and push your crop toward peak performance.
