Indoor Farming Faces Sustainability Questions Despite Expansion

Indoor farming companies like Eden Green Technology are building more greenhouses despite struggles and bankruptcies of competitors like AeroFarms and AppHarvest.

Advocates say indoor farming uses less water and land, allows growing closer to consumers, and protects crops from climate change.

But experts question the sustainability due to high energy costs for artificial lighting. Some think investment is better spent on outdoor farming solutions.

Pest problems can be created in indoor farms without natural predators, requiring close monitoring and pest management.

Companies claim they've figured out lighting efficiency and other solutions, but some experts doubt the profitability and viability of many indoor farming operations.
