Greenhouse Lettuce
Lactuca sativa L. var. crispa L.
Lettuce cultivation in greenhouses is based on the use of hydroponic racking systems and low-volume technologies, which allow for precise control of nutrition and microclimate.
In the reference 21 varieties crop Leaf lettuce, where this is mentioned in the description.
Industrial greenhouse lettuce production typically employs nutrient film technique (NFT) and ebb-and-flow systems, with the product marketed in pots with substrate. The crop is highly sensitive to light levels, necessitating the selection of shade-tolerant cultivars, particularly butterhead types, during the autumn-winter period.
The optimum temperature for lettuce seed germination is 20–22 °C; temperatures exceeding 25–28 °C induce dormancy. During the growing process, the crop is sensitive to high air humidity and elevated salt concentrations in the growing medium, requiring strict control of the nutrient solution and greenhouse microclimate.
