What is Final Flush™

Removes unwanted salts from growing media. During periods of high growth it is possible for a plant to absorb more nutrients than required. Final FlushTM removes excess salt from the media.
Helps plants during critical pre-harvest period. By removing the excess salt for around the roots a plant is force to metabolize any unconverted salts in its tissues leading to a cleaner end product full of natural tastes and aroma.

Can be used for correction mid-cycle. It is possible to add to much fertilizer while trying to achieve maximum yield which can have a negative effect on growing plants. In this case Final Flush can be used to pull nutrients away from roots giving plants a chance to rebalance.


SHAKE WELL before using. 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 10 ml of Final Flush per 5 L (2 tsp/5qt) 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 Applications:

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.
