    Hydroponics is a production technique considered part of precision agriculture due to its high productivity and quality. It is also an efficient alternative for vegetable production. However, the performance of lettuce (Lactuca sativa) can vary depending on the nutrient solution used. The objective of this study was to evaluate the production of Lactuca sativa var. Great Lakes under the effect of four nutrient solutions in a Deep Water Culture (DWC) system under greenhouse conditions. A completely randomized design with four treatments and four replicates was implemented. The variables evaluated at eight weeks were: plant height, number of leaves, stem diameter, root length, head diameter, fresh weight, and dry weight. The results of the statistical analysis show significant differences between the treatments for most variables, with the exception of the number of leaves, head diameter, and stem diameter. Treatment 1 (La Molina solution) showed the lowest values, with a plant height of 17.6 cm, stem diameter of 16.8 mm, root length of 44.5 cm, fresh weight of 342 g, stem dry weight 0.90 ± 0.63 g, root dry weight 1.01 ± 0.50 g, and leaf dry weight of 6.47 ± 3.14 g. Treatment 3 (Aqua Payana solution) showed the highest values for root length 71.1 cm, stem diameter 21.4 mm, fresh weight 695,10 g, stem dry weight 1.20 ± 0.43 g, and root dry weight 1.38 ± 0.51 g. Treatment T4 (FAO solution) showed the highest leaf dry weight 10.14 ± 2.60 g. This highlights the importance of using a balanced solution that meets the needs of the crop.
