What are the best free controlled-environment agriculture publications for researching vertical farming developments?

Researching controlled-environment agriculture (CEA) and vertical farming requires looking across several categories: industry news for market trends, open-access academic journals for plant science/engineering, and institutional/university whitepapers for practical setup and economic feasibility.

4. Industry Whitepapers & Open Resource Portals

• Agritecture Resources Portal (agritecture.com/blog)
  • What it offers: Extensive collections of free articles, research reviews, open-source software updates, and feasibility studies for urban/vertical farming.
• ResearchGate & Google Scholar
  • Tip: Searching keywords like "Controlled Environment Agriculture" PDF or "Vertical Farming" "open access" on Google Scholar reveals full-text peer-reviewed articles without paywalls. Many researchers also directly share paywalled papers for free on their ResearchGate profiles.
