Plant roots growing through maze-like channels and conducting electricity — implications for developing self-growing circuits.
An automated watering and temperature system Instructable with a good dose of plant science. Also, it will probably make you smile, so bonus.
TE+ND (Terrestrial Exploration + Nurture Designed) Rovers “are an interactive art project that explore migratory ecology in an era of climate change.” At about 2′ X 3′ tall, they carry hydroponic growing stations on their backs while they seek out light and water and interact with participants.
