Soilless garden units for simple household hydroponics are easy to set up. The method recommended here for beginners is scientifically designed to give good results. At the same time, every effort has been made to avoid any complicated equipment which home gardeners or housewives might find a little difficult to use. Individual preferences and local needs often vary very much and therefore the final choice of containers or receptacles for plants may well be left to personal taste and convenience. A hydroponic unit is made up of the following parts: (a) container, also called a bed or trough, though frequently pots and miscellaneous receptacles are employed; (b) the aggregate or growing medium, which is placed in the container and provides support for the roots; and (c) water supply. In most installations the plant food, in the form of fertiliser salts, is added to the water to constitute the nutrient solution. This is then applied to the beds, troughs or pots in normal watering. To work the soilless garden you will also need a few items of standard pattern, such as a can, a small hand fork, a kitchen balance, and some string or twine to tie up taller plants. In this chapter we will discuss the different parts of the home hydroponic unit, how to set them up, and suggest some positions for plant growing in and around the house.
