How do the plant pillows used for growing lettuce in the ISS work?
So how do the plants receive light in space?
The plants in the ISS receive light through a combination of natural light and supplemental LED lighting. The ISS has specially-designed growth chambers that are outfitted with LED lights that are carefully calibrated to provide the optimal spectrum for plant growth. This helps compensate for the lack of sunlight that plants would receive on Earth.
