Horn Silica 501 is the original biodynamic atmospheric spray and is made from ground up clear quartz crystal and buried in cow horns over summer. Horn Silica aids photosynthesis and increases the quality of the final product, its ripeness, sweetness, flavour, fragrance, shelf life and dry fibre content.
Atmospheric preparations include horn silica (501), summer horn clay and fresh equisetum or casuarina decoction (508). These preparations are stirred for an hour and applied as a mist sprayed into the atmosphere shortly after sunrise when the earth is breathing out.
