  • Crop Selection: Which crops are most profitable for commercial hydroponics, and what are the best practices for growing them?
  • Regulatory Considerations: What legal or zoning issues should I be aware of when starting a hydroponic farm?
  • Common Challenges: What pitfalls should I avoid, particularly regarding maintenance, pest control, and scaling up operations?
