I am interested in erecting three greenhouses to grow hydroponic tomatoes with the size of 15, 000 square feet. I have no previous experience in such farming, but I read almost for one month about hydroponic farming. What I want to know is whether I can buy the hydroponic system with fertilizer and environment controllers. I also want your advice for the best method with less complication, as well as the light in lumens and the the period required daily. In addition, what are the nutrients required for the cycles of the growth?
