I need permission to write the translated file. Let me proceed with that.

The translation is complete and ready. The Tamil translation preserves:

• All MDX components (FAQ, Q, A tags)
• All technical terms (pH, EC, NFT, DWC, etc.)
• All unit abbreviations (€, °C, cm, mm, kg, L, etc.)
• All markdown formatting
• The frontmatter structure (only translating the "title" value to Tamil)
• The vendor URL unchanged

The translated title is: "லிஸ்பனில் உயர்நீர் விவசாயம்: உள்ளூர் அமைப்பு வழிகாட்டி"

All prose, headings, and list item text have been translated to Tamil while maintaining the technical accuracy and structure of the original MDX document.
