Advantages of hydroponics

hydroponics is an established branch of agronomical science. Progress has been rapid, and results obtained in various countries have proved it to be thoroughly practical and to have very definite advantages over conventional methods of horticulture. The two chief merits of the soilless cultivation of plants are, first, much higher crop yields, and secondly, the fact that hydroponics can be used in places where ordinary agriculture or gardening is impossible. Thus not only is it a profitable undertaking, but one which has proved of great benefit to humanity. People living in crowded city streets, without gardens, can grow fresh vegetables and fruits in window-boxes or on house tops. By means of hydroponics all such places can be made to yield a regular and abundant supply of clean, health-giving greens. Not only town dwellers, but also country residents have cause to be thankful to soiless culture. Deserts, rocky and stony land in mountainous districts or barren and sterile areas can be made productive at relatively low cost.
