Grotek Final Flush Regular (1L)


Grotek Final Flush 1L is a solution developed exclusively for washing away excess fertilizer salts from your crops. Final Flush removes fertilizer salts from the substrate during the final stages of flowering plants, also helping to correct supercharging in soil, soilless and hydroponic systems.

Using Grotek Final Flush toward the end of flowering ensures that your plants retain their natural flavours rather than the harsh taste left by excess nutrients.

Use 7 to 10 days before harvest at a ratio of 10ml/5L water.


  • 0.6% ascorbic acid
