The simple answer to questions on light requirements for tomatoes is that you need a minimum of six hours to produce fruit, but eight or more hours of sun will produce the best results in terms of how many tomatoes you get.

The reason that light for a tomato plant is so important is that tomato plants convert sunlight into energy. Tomato plants need energy to make their fruit. Therefore, the more sunshine they get, the more energy they have and the more fruit they can produce.
