Final Flush™
– Fertilizer Rinse Solution –
Available in 6 scents, Grotek Final Flush™ is formulated to remove excess salt from growing media to ensure a cleaner tasting harvest. Plants tend to absorb excess nutrients and store them in plant tissues. By purging nutrients from the root zone, plants are forced to convert accumulated salts into secondary metabolites that improve harvest quality. The result is a top-quality harvest with the flavour and aroma you expect. Final Flush™ is available in Regular (unscented), Grapefruit, Green Apple, Pina Colada, Blueberry, and Strawberry.
Application Rate: 1L makes 500L of solution. *See Extended Application Rate below

Flushing with water only removes dissolved nutrients, whereas Final Flush™ contains powerful solubilizers that liquify and remove precipitated and absorbed nutrients.
To address nutrient imbalance or salt accumulation, apply the mixture liberally to the top of the container and allow any excess solution to drain out the bottom. Repeat a second time if necessary and then wait one week before resuming a regular feeding program.
