The U.S. greenhouse produce sector has experienced substantial growth, reaching a total production value of $3.2 billion in 2025. This represents a 12% increase from 2024 figures, driven by consistent year-round consumer demand for fresh vegetables such as tomatoes, cucumbers, peppers, and leafy greens. Factors contributing to this expansion include increasing climate challenges that favor controlled environments and a consumer shift toward locally sourced, sustainable food options. Preliminary data from the USDA 2026 report indicates that greenhouses now account for 25% of U.S. specialty crop output, with controlled-environment agriculture (CEA) expanding by 18% in planted area to 1,200 acres nationwide. This growth underscores the increasing importance of these facilities in securing the nation's fresh produce supply.

Methodology for Ranking

Our ranking of the top 10 largest greenhouse produce growers in USA for 2026 is based on 2025 annual production volume, measured in million pounds of produce. This represents the most recent full-year data available as of March 2026. Data sources include the USDA National Agricultural Statistics Service (NASS) Greenhouse Crops report, released in February 2026, supplemented by company disclosures, Rabobank CEA Market Intelligence from Q1 2026, and trade group statistics from the Association of Protected Agriculture (APA). In instances of tied production volumes, revenue from greenhouse sales and total facility square footage were used as tie-breakers. Our analysis specifically focuses on pure greenhouse operations, excluding outdoor or hybrid farming models. The primary crops contributing to these volumes are tomatoes (42%), cucumbers (22%), peppers (18%), and other produce (18%). All included operations demonstrate an output exceeding 50 million pounds per year.
