This study aims to determine the effect of additional compact fluorescent lamp (CFL) light on the production, morphology and physiology of tomato plants, as well as their efficiency. The research also examined the prospects for planting tomatoes in simple plastic houses at the height of the medium in tropical countries. The experiment was conducted in a plastic house in the tropical region of East Java, Indonesia, with a place altitude of 455 m above sea level. The design used was the Split-Plot Design, with 3 replications. The treatment consisted of 2 factors: the main factor was 4 levels of additional CFL light at night (no light/control, 4 hours, 8 hours, and 12 hours), and the sub-factor consisted of four tomato varieties (‘Juliet’, ‘Golden Sweet’ and ‘Betavila’). Tomato plants of the ‘Juliet’ cherry variety (indeterminate) showed a higher plant growth rate when given additional CFL light for 8 hours, while the ‘Betavila’ variety showed a higher plant growth rate when given CFL light for 4 hours. ‘Betavila’ also produced the highest yields, especially under 4 hours of night lighting. Meanwhile, the ‘Juliet’ cherry variety achieved the highest yield with 12 hours of CFL light. Farming analysis showed that the ‘Betavila’ variety was more profitable without CFL lights at night, while, ‘Juliet’ variety was more advantageous when given lights for 4 hours before dawn. © Articles by the authors;
