Peggy Bradley and Cesar Marulanda have just published Home Hydroponic Gardens . Information on the book can be found here. Hydroponics Simplified hydroponics is a vegetable production method that utilizes modern day hydroponic technology adapted for areas with limited resources. This technology is based on minimal inputs, requiring no pumps, energy, or expensive equipment. The gardens are built with recycled or discarded containers, hand watered once a day with a commercial hydroponic nutrient.
Recipes also exist for making an organic nutrient at home.
Designed by Colombian mechanical engineer, Jorge Zapp, the project used hydroponic growers, made of small containers and discarded wood pallets, placed on rooftops, balconies, stairs, and any available space in the sun. The women earned as much as three times more than their husbands earned in semi-skilled jobs, and provided food from the families from overripe or less than perfect crops. They produced 30 types of vegetables in their hydroponic gardens. The gardens were built of donated or recycled materials including rice bran from a mill, wooden crates from an auto parts shop and recycled polyethylene from commercial flower growers. Pallets were set flat on the roof and the top slats were removed.
