PK Kompakt 20-45 is a high-concentration solid PK fertilizer developed specifically for the final stage of flowering, when crops demand maximum performance in weight, density, and quality. Its precise and highly soluble formula delivers phosphorus and potassium in optimal proportions to stimulate the formation of compact, uniform flowers with higher final value.

During advanced flowering, plants require increased phosphorus to drive flower production, and potassium to improve tissue structure, size, and resistance. PK Kompakt 20-45 acts as a targeted technical booster, supplying these key nutrients exactly when the crop needs them most.

Thanks to its low chlorine content and fine granulometry, this fertilizer dissolves easily and can be applied directly in irrigation water. This ensures fast and efficient nutrient uptake, prevents lockouts, and promotes uniform development across the entire crop.

Its formulation is designed for high-value crops, both indoors and under LED lighting, where flower density and consistency make a significant difference. The result is a more compact yield, with greater weight and a more attractive final appearance.

PK Kompakt 20-45 is a technical finishing tool for the final weeks of flowering. When applied at the correct dosage, it helps maximize the crop’s genetic potential, ensuring denser, more uniform, and higher-quality harvests.
