Post-Harvest Nutrient Mix

Harvest many times and keep growing!  These are the nutrients you add to your culture after harvest. They make up for the nutrients absorbed by the harvested Spirulina, to assure continued growth.  This is an optimized mix, providing faster grow-back than the “classic” mix in my book.  One bottle is good for 14.3lbs. (6.5kg) of well-squeezed fresh Spirulina harvest.
