EDEN is a farming machine.

Thats the short and simple way to put it.

For the technically inclined - EDEN is a computer-automated vertical aeroponics environment. EDEN consists of a sensor and actuator network controlled by a Raspberry Pi Zero paired with an Arduino Due.

The sensors monitor environmental variables like:
• liquid levels
• nutrient pH
• temperature
• humidity
• carbon dioxide concentration
• active light ratios'

The information gathered is used to automatically control:
• watering cycles
• nutrient pH
• lighting
• air quality

EDEN offers a robust environment for plant growth that is sustainable and reliable. While daylight varies with weather conditions, pests, and pollution, EDEN can overcome those challenges anywhere on Earth. Indoors. Earth has a limited number of places suitable for farming outdoors, but growing indoors can be done anywhere - including space.

Often times genetic engineering is used instead, by adjusting the genotypes of plants to survive in conditions that would not be feasible otherwise. EDEN leaves the genetics to nature, while ensuring a biotic environment that produces strong phenotypes. Changing the environment to suit the organism, instead of the organism to suit the environment.

Earths current population is over 7 billion people, with life expectancy increasing along with high birthrates. When outdoor farming uses land in climates that people require for housing - the demand for food will inevitabley increase. To support this increase food must be grown in more places, more densely, and reliably. Thats where EDEN comes in.

EDEN features a verticle column which can support over 60 plants in less than a square meter of space. Growing 3 dimensionally offers more produce than 2 dimensional farming.

Agriculture also has the largest use of fresh water, something must be done to ensure people have clean drinking water in addition to plants. Aeroponics can be used to save over 90% of the water that is lost to the ground when plants are watered in dirt. The technology is used by NASA in space to deliver fine mist particles directly to the roots of a plant. This also prevents pollution caused by fertilizer runoff into streams and other bodies of water.

Pollution is a major issue caused by farming, and also a major threat to farming. EDEN absorbs up to 5 times more carbon dioxide per plant than outdoor plants can. This is accomplished through a process known as CO2 enrichment, which feeds plants additional CO2 with use of bright lights. CO2 enrichment results with quicker growth by greater absorption of water plus carbon dioxide (plants are HYDRO-CARBONS).

While indoor farming isn't exactly new - LED technology is. In the past indoor farms typically relied on high power lighting arrays to replace sunlight. EDEN consists of 360 horticultural LEDs to reduce the redundant spectrums of solar light that plants don't use much of. The technology is referred to as PAR, Photosynthically Active Radiation, and it is much more energy efficient. NASA/ESA scientists are also experimenting with this technology to give plants the most optimal "light recipes" for photosynthetisis.

The Raspberry Pi controlling EDEN is programmed to handle the entire growth cycle from sapling to fully grown plant. Each node will be networkable to work on an industrial scale, with configuration profiles that can be scientifically analyzed to observe the best factors for plant growth. With internets of farms, the future can be fed.
