Hydroponics is the practice of growing plants in nutrient-enriched water rather than soil.
Hydroponics is incredibly productive and requires little space. For example, Factor e Farm's experiments found that they could grow $1 of lettuce per square foot per week. And the Institute of Simplified Hydroponics has found that they can grow 2kg of vegetables a day on 20m2 of space [1]. Indoor growing in a greenhouse greatly reduces losses to pests.
See here for free instructions on building several different hydroponic systems. N55 have a design for a vertical hydroponic system here. See Wikipedia on hydroponics for more information.
Open source software for automating hydroponic systems.
Aquaponics is a kind of hydroponics that uses the water from fish tanks. This eliminates the need for an input of nutrients.
Open-source hydroponic nutrient
You can mix hydroponic nutrient cheaply using mineral salts that most chemical suppliers have. The necessary ingredients are:
- Monopotassium phosphate (KH2PO4)
- Potassium nitrate (KNO3)
- Calcium nitrate (CaNO3)
- Magnesium sulfate (MgSO4)
- Boric Acid (H3BO3)
- Manganese chloride (MnCl2)
- Zinc sulfate (ZnSO4)
- Copper sulfate (CuSO4)
- Iron sulfate (FeSO4)
- Ammonium molybdate
