Abstract: Low cost hydroponics devices were designed using plastic trays and buckets. Cultivations of tomato, chilli, cauliflower and marigold cv. Inca were tested in these devices using rain water, pond water, tap water and distilled water for nutrient solution preparation. The vegetables were grown as multiple plant cultures in plastic trays and marigold cv. Inca in single plant culture in small buckets. Direct use of tap water and pond water created chlorosis in some plants that could be overcome by boiling of water before use. In rain water tomato and chilli plants performed the best. However, cauliflower curd yield was the best in tap water. Marigold cv. Inca bloomed well in all categories of water. Water qualities were the major factor for crop growth. Rainwater could be more safely used. The devices and procedures are recommended for the kitchen gardeners of the urban and soil stress areas.
