Bio Diesel Crystal Clear
Bio Diesel Crystal Clear is a premium, organic flushing solution engineered to deliver a cleaner, sweeter finish for your harvests. Specially developed for coco fibre and peat-based systems, Crystal Clear combines complex sugars with organic acids to break the ionic bonds between nutrient salts and your growing media. This process releases locked-up fertilisers and accumulated minerals, restoring a balanced root zone and paving the way for improved nutrient mobility in the crucial final stages of growth.
Unlike traditional flushing methods that rely on large volumes of plain water, Crystal Clear works with far less, reducing water waste while avoiding the stress that over-flushing can cause. By gently cleansing the media and improving nutrient transport, it promotes higher Brix levels, enhanced terpene production, and vivid colour expression in flowers. The result is improved flavour, aroma, and quality without compromising plant health.
Crystal Clear is equally effective as a final pre-harvest flush or as a corrective measure mid-cycle to remove excess salts and restore optimal conditions. Safe for use in all coco and peat-based systems, it integrates seamlessly into existing feeding programs to help growers achieve consistently clean, high-quality yields.
