Grotek Final Flush Nutrients

Brought to you by Grotek

Grotek Final Flush is a professional-grade flushing solution designed to remove excess nutrient salts and built-up residues from your grow medium, ensuring cleaner flavour, smoother smoke, and superior crop quality. Trusted by growers worldwide, Grotek’s advanced formulation supports a proper end-of-cycle flush, helping plants finish strong while preserving terpene profiles and essential oils.

This powerful flushing system works by breaking down and mobilising nutrient build-up within the root zone, allowing plants to naturally use up stored nutrients before harvest. The result is improved taste, aroma, and overall product purity, making Grotek Final Flush an essential tool for hydroponic, soil, and coco growers seeking top-tier results.

Whether you're cultivating cannabis, herbs, fruiting plants, or flowers, Grotek Final Flush ensures a professional finish every time, helping eliminate harshness and improving post-harvest quality. Suitable for all growing systems, this combo is ideal for final-week flushing and corrective nutrient reset applications.

Especially Suitable For

• Final flushing phase before harvest

• Hydroponic systems (DWC, NFT, drip, recirculating systems)

• Coco coir grows

• Soil-based cultivation

• AutoPot & automated irrigation systems

• Cannabis cultivation

Application

Grotek Final Flush is designed to be used during the final stage of flowering or before harvest to help remove excess nutrient salts and reset the root zone.

How to Use:

• Mix equally into fresh water.

• Apply as your regular feed or irrigation solution.

• Use for 3–7 days prior to harvest, depending on grow medium and crop type.
