Grotek Final Flush

Final Flush is formulated to remove excess salts from your 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. Derived from Potassium Sorbate, Citric Acid.

Grotek Final Flush Application:

1L makes 500L of solution.

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 Final Flush 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.

Observe for visible signs of excess fertilizer salts such as the appearance of a white, powdery residue on the surface of the growing medium.

Use 2 tsp of Final Flush per 5 qt (10 ml / 5 L) of water. Safe to use while plants are growing or between crops.

Hydroponics: Add Final Flush mixture to pure water in the nutrient reservoir and run the system for about one hour.

Soil/Soilless/Water Culture: Salt Accumulation: Apply Final Flush 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.

Prior to Harvest: Use mixture 7-10 days before harvest, to remove unnecessary fertilizer salts and fertilizer flavors.
