Effects of Light-diffusing Plastic Film on Lettuce Production and Quality Aattributes

  In general, plants grown under diffuse light yield higher biomass than those grown under direct light as a result of a more uniform distribution of the light across the plant canopy. We compared the effects of a light-diffusing plastic film and a clear plastic film on growth of Batavia...
