We are pleased to have cooperated with the Tennessee Department of Agriculture Market Development Division in this “Preliminary Evaluation of Concepts for Growing Leafy Vegetables Hydroponically in Tennessee.” This report summarizes almost six months of review, observation, discussion and analysis of numerous concepts and practices of hydroponic greenhouse operation. This type of preliminary evaluation of new and developing production practices, market opportunities, and feasibility is an essential initial step to the ultimate identification and development of viable farm enterprises.

Dr. Alvin Rutledge, professor emeritus of The University of Tennessee, has done an excellent job establishing parameters for this study; identifying, describing and defining alternative production systems; considering market possibilities; prescribing broad and specific production practices; and developing a straightforward cost analysis. Dr. Rutledge provides and overview of the potential of hydroponic lettuce production in Tennessee by comparing specific practices of two different systems.

A special thanks is extended to Dr. Rutledge for his many contributions to this project as the principal investigator. Thanks is also extended to Dr. Allen Straw, Dr. Dave Coffee, Dr. Charlie Hall and Ms. Wanda Russell for their assistance in the review process. Appreciation is extended to Mr. Stanley Trout, Mr. Joe Gaines, Mr. Paul Nordstrom, Dr. Dan McLemore and Mr. Dan Wheeler for their support and direction of this project.
