Hydroponics have been shown to be a successful technique for growing of plants. Yet most of the crops are still grown on land. Why?  

Answer:

                  Although, hydrophonics is a successful technique for plants still many crops are grown on land because (i) The cost is the major concern. The setting and handling of hydrophonics requires much more investment than that of the soil based production. (ii) Sanitization is extremely important especially with indoor hydroponic environments. Water borne disease can spread quickly through some methods of hydroponic production. (iii) Hydroponics is relatively a new technique and not used by the traditional farmers due to lack of knowledge. (iv) Plants are less adaptable to the surrounding atmosphere. Hot weather and narrow oxygenation may minimise the production and quality of plant produce/yield.
