To grow tomatoes under a controlled agronomic system (CAS), several factors must be taken into account. One of them is light, which is important for plant life. We know that during the winter months the length of daylight hours is 9-11 hours, which, in turn, leads to an extension of the growing season of the tomato plant. Early in the morning and in the late afternoon before sunset, an additional 2-3 hours of light was given to increase yields.
