Grotek - Final Flush Grapefruit is a premium flushing solution.

When growing plants in containers and recirculating systems, salt can build up and cause problems for growing plants and also it can make the harvest at the end taste bitter. Final Flush encourages your plant to use up any left over nutrients and rids your plant of excess salts. It is a great product to use if you've accidentally over-fed your plants. It is also ideal for using 1 / 2 weeks before harvest to ensure your end result is clean and free of any residues and metallic tastes.

Final Flush can be used on any medium and in any grow system.
