Harvesting Flush Solution for a Cleaner Finish
Grotek Final Flush is a finishing solution designed to help remove excess nutrient salts and built-up fertiliser residues from the root zone in the final stage before harvest.
Used during the last 7–10 days of the cycle, it helps clean the growing medium so plants can finish in a cleaner root environment rather than sitting in accumulated nutrient build-up.
Suitable for hydroponics, coco coir and soil, Grotek Final Flush is a simple way to support a proper flushing phase before harvest.

Why You Need It
Over the course of a grow, nutrient salts can build up in the medium. If that build-up is left in place right until harvest, plants finish in a dirtier root environment than they need to.
Grotek Final Flush is designed to help dissolve and mobilise these built-up salts so they can be removed more effectively during the final flushing period.
That makes it a useful tool for growers who want a cleaner finish before harvest without complicating their routine.

Top Tip
Start using Final Flush when plants are entering their final ripening stage, not after they’ve already gone too far. A properly timed flush makes the whole finishing phase easier to manage.
