Disadvantages of high-tech farming

The hydroponic conditions (presence of fertilizer and high humidity) create an environment that stimulates salmonella growth.Another disadvantage is pathogens attacks including damp-off due to Verticillium wilt  caused by the high moisture levels associated with hydroponics and overwatering of soil based plants.

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.

Introduction to Hydroponics Farming


Hydroponics farming is a method of growing plants using mineral nutrient solutions, without soil. Terrestrial plants may be grown with their roots in the mineral nutrients solution only or in inert medium, such as perlite, gravel or mineral wool.
