Greenhouse Lettuce
Lactuca sativa L.
Growing lettuce in a protected environment requires strict control of salinity, pH levels, and a specific temperature regime, which is significantly lower than that of tomatoes or cucumbers.
In the reference 755 varieties crop Lettuce, where this is mentioned in the description.
Lettuce is extremely sensitive to soil salinity, responding to it with the development of marginal leaf burn. To prevent manganese toxicity, it is necessary to maintain a pH level of 6.5, which converts micronutrients into a poorly soluble form. In hydroponic cultivation, the ebb and flow method is more effective than the nutrient film technique, as it contributes to an increase in biomass and dry matter content.
Unlike thermophilic vegetable crops, lettuce requires a temperature maintained at 18–20 °C for growth and 12–14 °C for head formation. Disruptions to the microclimate and high temperatures in greenhouses during the summer period trigger premature bolting, which reduces the commercial quality of the produce.
