Spirulina thrives in warm, sunny environments. Select a location with the following features:
- Temperature: 30°C to 35°C (ideal).
- Sunlight: Requires 8-12 hours of sunlight per day.
- Water Source: Access to clean, alkaline water (pH 8.5 to 11).
2. Setting Up the Pond or Tank
You can grow spirulina in either open ponds or closed tanks. For beginners, a small tank is ideal.
