Targeted LEDs: Photosynthesis Power in Space?

If we end up in space, seeking carrots, bok choy, and other sustaining vegetables, we'll be very glad we have LEDs to power the plants in all that darkness. Or, that's one possibility. In the mean time, it's excellent to expand the ways we can keep plants alive in limited conditions, such as underground, in vertical situations, or in space. That is, researchers with Purdue University, in a study funded by NASA, have been thinking along those lines, according to a release. They have found that red and blue LEDs used in a targeted way can provide energy-efficient lighting to stimulate photosynthesis. Knowing this could advance the development of crop-growth areas for space exploration.
