Aeroponics
From Hackerspace.gr
Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics).
This project's main objective is to develop an open source aeroponic system for home grown edible plants, that one can easily build without much technical knowledge and with readily available materials and tools. Having and using such a system will provide immediate control of and access to fresh food of superior quality and of known origin.
