A short intro on hydroponics:
Hydroponics (from the Greek words hydro water and pono labor) is a method of growing plants using mineral nutrient solutions, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, or mineral wool.
-Since i have a very strong interested in sustainable development, as well as closed ecosystems (the Biosphere 2 experiment, for all its failings , left a permanent mark on my mind as a kid), i have started work on multiple types of hydroponics systems.
- The first one is a “deep water culture” system : very simple , yet efficient: check the progress out here
- The second one is a bit more complex, but has the potential of being the one that uses the less water for the best results : it is using an Arduino to control a small water pump in a home made ebb and flow system: its the “Hydroduino“!
When i have the time and the equipment i wil expand the Hydroduino to a fully automated closed and controled growth system, (temperature and water level monitoring, led based lighting).
-April 2010 update : the Hydroduino project is moving along at a good pace since I finally had more time for development, some big updates coming up soon! Also, this was written from an Android based cellphone, so there will be Android centered sub projects too !
