Hydroponic production of lettuce in the United States has grown exponentially in the last decade with Bibb Lettuce (Lactuca sativa var. capitata L.) being the most popular variety grown. However, research into different spacing requirements of Bibb grown hydroponically as compared to traditional field growing has been limited. This information has become crucial as hydroponic operations move into urban areas where space is limited and available area must be utilized efficiently. Development and yield of three crop rotations of Bibb lettuce were evaluated using a modified Nutrient Film Technique (NFT) hydroponic system, which maximized amount of lettuce grown per square foot. Each crop rotation utilized different layouts to test effects on plant growth and harvest weight: single spaced, double spaced, and a combination of the two. The three rotations were heavily impacted by rough weather, during experiments, however, results show slightly more robust heads in the double spaced trial, both in edible mass weight and crop efficiency. These results indicate that close spacing of heads may have a negative impact on growth of the Bibb heads. ( en )
