Technology Background:
High population pressure, rising food prices, socio-economic and environmental stresses cause a serious challenge for food, nutrition, health and environmental security in urban and per urban areas. Hydroponic technology plays an important role in order to produce maximum food with efficient input use and low insect pest risks and prove worthiness on roof top and indoor gardening in metropolitan cities. Among the all-hydroponic systems nutrient film is most efficient for crop production but for short stature single harvest crop in single layer hydroponics or single row vertical hydroponics becomes uneconomical due to limited number of plant accommodation. Imported vertical system available is expensive and technically difficult to manage and cause shading when density increased in single row vertical structure. Hence indigenous design has been developed. Technology details:
CISH Triangular NFT Hydroponics design gives 2.5 times more yield per unit area by utilizing space vertically as compared with normal NFT. It allows more light penetration due to wider spacing in triangular shape in compare to single layer hydroponic system. Nutrient frequency is automatically regulated with timer and can be operated with solar panel in erratic electric supply condition. It is suitable for roof top gardening.
