Tomatoes are vegetables that play an important role because they contain a lot of nutrients that are beneficial to the body. Currently, hydroponic technology is introduced as a new direction in agricultural production. The research paper aims to find out the most suitable factors for the growth, development and increase of tomato plant yield. Research results show that in the nutrient solution experiment, when conducted on GA tomato variety with 3 nutrient solutions SH1, SH2, SH3, the nutrient solution SH2 plants grew and gave the highest yield. Experiment on the substrate with tomato variety GA on 4 different substrates, the formula CT3 (10-15% organic + 3-5% charred rice husk + 80-90% coir) for fast growth and highest productivity. In the seed experiment conducted on 3 tomato varieties GA, GB, GC grown on CT3 and nutrient SH2 substrates, the following results were obtained: GA, GB are heat tolerant and suitable for growing in greenhouses in the system. Drip hydroponics, GC varieties are not suitable for growing in net houses. GB variety is the most productive and resistant variety.
