Collection: Flushing and Finishing

A flush in the last week or two before harvest clears built-up salts from the growing medium, which is what a clean-tasting, clean-burning finish actually depends on. Shop Canna Flush, Advanced Nutrients Flawless Finish, Plant Magic Flush Finish, HydroTops Flush, Intense Nutrients Climax, and Final Flush in Green Apple, Strawberry or Blueberry. Follow the product's stated flush period — cutting it short defeats the point.
