How do the plant pillows used for growing lettuce in the ISS work?
I'm curious to know how the plant pillows used for growing lettuce in the ISS work. Can you explain it to me?
Certainly, I'd be happy to. Plant pillows allow crops to grow in microgravity environments by providing a stable, self-contained growth medium that is free of soil and mess. The plant pillows for lettuce growth in the ISS contain seeds, a rooting substrate, and a controlled-release fertilizer. The roots grow into the substrate and absorb the nutrients they need without soil.
