Water Quality Analysis

Your Water Profile

Water hardness near Miami measures approximately 235ppm, classifying it as Very Hard.

⚠️ Hard Water Alert

High calcium and magnesium levels can accumulate in potting soil over time, causing brown leaf tips and nutrient lockout in sensitive species.

Recommended Actions

  • • Use filtered or distilled water for Calathea, Ferns, and Orchids
  • • Flush soil with distilled water monthly to prevent salt buildup
  • • Consider an under-sink RO system for large collections
  • • Repot annually with fresh soil for sensitive plants
