Hydroponics is a method of growing plants without soil, using only mineral nutrient solutions in water. Terrestrial plants are grown in pipes with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium such as sponge. This soil-less technology has been adopted at PEEDA (Technical Support of Windpower Nepal Pvt. Ltd.), where green leafy vegetable like lettuce, rocket, celery are grown in office open spaces. It is observed that, growing in this system requires less time and also ensure no bugs or dirt. With rapid urbanization of Kathmandu and with land getting increasingly scarce and expensive, hydroponics assures best use of gardening space.
