Preparation 501
This preparation strengthens the plants, making them more disease-resistant, particularly cryptogamic disease. It is made from crushed quartz and cow horn. It is used more particularly to stimulate the above-ground part of
plants, and promotes the processes stimulated by light and warmth: flowering, fruiting, ripening, structuring, concentration, etc. The powdered quartz and horn act as an extra burst of sunlight for the plants.
