Aeroponics for propagation of horticultural plants: an approach for vertical farming

Aeroponics is the technique of growing plant in soilless system in which roots hanging in the air acquire nutrition from spraying of nutrient mist. Although aeroponics was developed initially for the study of root system and related aspects by researchers, its paramount success in commercial crop production and large scale clonal propagation made soilless culture and vertical farming a sustainable concept for future. The technique is superior in terms of water use efficiency, less time and space requirement, seasonal independence, disease free plant propagation, large scale plant production etc. than the conventional methods of propagation. Thus it is widely being utilized in the field of horticulture as well as forestry also.
