Aeroponics: A Compliment to Hydroponics and the Food System of Space

Aeroponics, the process of growing plants in an air environment without the use of soil or a medium, has caught the attention of farmers and space voyagers alike. The process, which entails spraying a suspended plant’s dangling roots with nutrient-rich water, takes place within a controlled environment, with little exposure to outside influences. As a result, the environment boosts plant development, growth, health, and flowering. Aeroponics is often coupled with hydroponics, creating a blissful relationship that advances plant yield and turnover rate. In the 21st Century, alternative food systems are constantly being researched; moreover, aeroponics has the potential to eradicate current commercial food procedures, due to its ease of cultivation and quick crop rotation.
