Bio Diesel Rhino PK
Bio Diesel Rhino PK is a high-performance, 4-in-1 bloom booster formulated to maximise flower development, density, and quality in the crucial final stages of growth. Combining tank-stable, high-analysis phosphorus and potassium with complex carbohydrates, amino acids, and a targeted vitamin complex, Rhino PK delivers the essential elements plants need to push yields and resin production to their peak.
The phosphorus and potassium work together to drive explosive flower formation, while the carbohydrates and amino acids promote larger, denser buds with improved terpene and essential oil profiles. The included vitamins support faster nutrient uptake and help plants manage environmental stress, ensuring they maintain structural integrity and vibrant colour through to harvest.
Designed for use in all growing systems, soil, coco, and hydroponics, Rhino PK integrates seamlessly into existing feeding programs. Its clean, soluble formulation ensures efficient delivery without blockages or residue, making it a reliable choice for growers looking to achieve heavier harvests and superior quality.
