What is controlled environment agriculture?
CEA grows food in fully controlled environments that hold optimal conditions for plant growth: sealed greenhouses and vertical farms with complete climate control, soil-free hydroponic nutrient delivery, and light, temperature, humidity and CO₂ tuned to each crop.
Up to 95%less water than open-field farming
365 daysof harvest, every year
The payoff is pesticide-free produce with seed-to-shelf traceability, optimized water and energy use, and food grown beside the point of sale instead of trucked across the country.
Greenfield's CEA technologies
- Hydroponics — soil-free cultivation with optimized nutrient solutions.
- LED lighting — light that mimics the sun for optimal plant development.
- Environmental control — monitoring and regulating temperature, humidity and CO₂.
- Automation — intelligent systems for irrigation and nutrient management.
Vertical towers maximize space for leafy greens and microgreens, while vertical channels handle a wide range of vegetables with efficient irrigation.
What residents can eat
| Leafy greens | Lettuce, arugula, spinach, kale |

Why it works for communities
- Local production — freshness guaranteed by growing inside the community.
- Sustainability — a smaller footprint through efficient use of resources.
- Fast commercialization — produce is available immediately after harvest.
- Food integrity — complete traceability from farm to table.
GHI container farms are custom-designed to match the community's aesthetics while producing nutritious food daily, without harmful pesticides or chemicals.
A competitive edge for developers and HOAs
