Grotek Final Flush

Grotek Final Flush is a specialized flushing agent designed for use in the final 7–10 days before harvest. It effectively removes accumulated nutrients and salts from both plants and growing medium, working across soil, coco, and hydroponic systems. Excess nutrient buildup can result in bitter-tasting harvests and diminished flavour profiles. Final Flush eliminates these unwanted residues, ensuring cleaner, more flavourful crops at harvest. Beyond pre-harvest preparation, Final Flush also serves as a mid-cycle correction tool for overfeeding. Simply discontinue base nutrients and supplements, apply Final Flush, stabilize your plants, then resume your normal feeding schedule. Even if used mid-grow to address feeding issues, a final flush during the last 7–10 days of the cycle will maximize flavour and crop quality at harvest.
