or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: A primary challenge to growing plants in microgravity is the delivery of adequate air, water and nutrients to a plant's roots. Microgravity alters conv

ection and thus the behavior of root zone aeration which plants are evolutionarily reliant upon to grow. Current nutrient delivery techniques proposed for space involve the use of a medium for the roots to penetrate, such as arcilite, and p
