GROTEK Final Flush – Harvest Flush Solution
Grotek Final Flush is a finishing solution designed to help remove excess salts and nutrient build-up from the root zone in the final stage before harvest. Used during the last days of the flowering cycle, it helps clean the growing medium so plants can finish naturally without accumulated nutrient residues.
Available in a range of flavours, Final Flush is suitable for hydroponics, coco coir, and soil systems. It works by helping dissolve and mobilise built-up nutrient salts in the growing medium, allowing growers to properly flush their crops before harvest.
Please note: these items are purchased to order so extended lead times will apply.

Why You Need Grotek Final Flush
Over the course of a grow cycle, fertilisers and mineral salts can build up in the growing medium. If not properly removed before harvest, these residues can remain in the root zone and affect how plants finish their final stage of growth.
Final Flush is designed to help break down and remove this build-up so growers can properly flush their plants before harvest. By clearing excess nutrients from the medium, plants can complete the final stage of flowering in a cleaner environment.
How to Use Grotek Final Flush
- Use during the final stage: Apply during the last 7–10 days before harvest.
- Mix with water: Add 2ml per litre of Final Flush to clean water.
- Water plants thoroughly: Apply enough solution to fully saturate the growing medium.
- Repeat if required: Continue using during the flushing period until harvest.
Top Tip: Begin flushing when plants are approaching their final stage of flowering. Using a flushing solution like Final Flush can help remove accumulated salts from the medium before harvest.
