Grotek Final Flush helps during the critical pre-harvest period by removing the excess salt around the roots. This forces the plant to metabolize any unconverted salts it may have, this helps to produce an end product full of natural tastes and aromas.
Grotek Final Flush can also be used mid-cycle to help with over fertilization. Final Flush pulls the nutrients away from the root base, giving the plant a chance to re-balance itself.
Always shake well before use and store in a cold dark place.
Grotek Final Flush is suitable for soil, coco and hydroponic solutions.
MIXING GUIDE: Soil and Coco: 10ml per 5 Litres of water. Use 7-10 days prior to harvest to remove unnecessary salt.
For over fertilization apply Final Flush liberally to the top of the container/pot and allow excess solution to drain out the bottom. Repeat a second time if necessary. Wait a week before resuming normal feeding program.
Hydroponics: Add Grotek Final Flush mixture to pure water in the nutrient system and run the reservoir for about one hour. Use 7-10 days prior to harvest to remove unnecessary salt. For over fertilization apply Final Flush liberally to the top of the container/pot and allow excess solution to drain out the bottom. Repeat a second time if necessary. Wait a week before resuming normal feeding program.
