Salinity can become a serious issue for those gardeners growing in containers and recirculation systems.

Salt build up can cause problems for growing plants and bitterness in harvested fruit.

Final Flush™ is a flushing agent designed to correct overfeeding issues during crop production and also eliminate excess salts from the medium during the final stages of plant growth.

Available in Regular, Strawberry, Pina Colada, and Blueberry.


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.
