Abstract:This paper describes the use of artificial lights (Super Bright LEDs) for crop Hydroponics. To compare the growth of plants grown in natural light. The experiments are carried out in a closed dark enclosure, the control of the lights (LEDs) are ON for 16 hours a day. The Temperature was maintained at less than or equal to 30ºC using an air pump  cycling on and off, the run time on being 30 minute’s. The design lamps used are super bright LEDs of different types, Fluorescent red to blue with a ratio of 3:1 when testing the growth of the 2 test plants (artificial light and led light) data was collected on the amount of light, temperature, and humidity, compared to growth. This data was then analyzed. The study found that the use of artificial light (LEDs.) the light intensity is lower than natural light having a temperature of 2-4°C, with a 1,438-1,442 Lux. The test plant using natural lighting and temperature grow the best in this study.
