Lettuce does not tolerate high humidity. Therefore, after the plants have grown, there must be plenty of ventilation to prevent the risk of rotting and in the interest of a good head formation. This is especially necessary after watering, so that the plants dry off quickly. In addition, the temperatures, especially during head formation, no over 24 rise to 25°C. As long as the stock hasn't closed, the soil must be constantly loosened. When the head begins to form, it is thoroughly watered again, to have to water as little as possible later. It is advisable to combine watering with the top fertilization that is necessary at this point in time.
