To start a spirulina farm, you need a warm climate (25-50°C), Fresh potable water and a contamination-free environment. Begin by setting up growth tanks (preferably food-grade material), an agitation system, and an organic nutrient supply. Ensure regular water testing, lab analysis for purity, and compliance with organic standards for targeting premium markets. Drying and packaging should use low-heat methods to retain nutrients. Marketing strategies should focus on B2B (nutraceuticals, pigment, cosmetics) and direct-to-consumer (powders, tablets, supplements). Hiring consultants can help you cover all bases and avoid costly mistakes during setup and operation.
