doubts about tomato plants throughout the year

NicolasGarcia · July 15, 2021

I have always wondered how the large agricultural tomato industries make available tomatoes throughout the year, in Spain I know that they have tomatoes throughout the year, although where they do it is in a tropical climate and mild winter in the greenhouse, but in winter It has fewer hours of sun, I wonder will they have heating in the greenhouse? will they have artificial lights? Will they keep the same tomato plants for years? I have ever tried to plant tomato plants obtained from a mid-season cloning and they have never developed correctly, their growth is very slow and they do not finish developing well, how will they do it?
Thank you
