At NASA and other space centers, they are investigating how to grow vegetables using artificial lights: That is also what they are doing.

As an electronics engineer specializing in lighting, Rodrigo Iribarren could have worked in any existing sector, but he decided to forge his own path in the field of indoor vegetable cultivation. The idea came from the "indoor" system commonly used for home cannabis cultivation. Typically, whether in a tent or a closet, these plants are fed with specific artificial light and a ventilation system. But also seeing how the trend of vertical farming was advancing worldwide, Rodrigo decided to combine both ideas and has since been seeking a way to produce vegetables without relying on sunlight and in small spaces. "The plants themselves need light energy, and they have no way of knowing what the source of that light is. Whether you're giving it with an LED, sodium, or the sun, the plant doesn't notice," explained the engineer in an interview with Bichos de Campo during the last Argentine hydroponics congress. However, this basic principle does not mean that any energy-saving light can ...
