   * Hydroponics is found to be way too complex and expensive in lot of eastern countries and some of african countries too. In these places, roof gardens build out of local materials are most suitable. They are repair and maintained by the communities themselves. This is seen in places like India, St. Petersburg and Senegal. Infact, in Senegal people have devised a local solution using bricks and wooden box beds. In India too, the use of locally available cheap materials to create roof gardens is most successful. The “Doshi System” is offered as the most suitable method. It uses sugarcane stalks, collected from sugarcane juice vendors outside of his house, as biomass. This is lightweight, allows water drainage, and keeps soil in place.   * Hydroponics is found to be way too complex and expensive in lot of eastern countries and some of african countries too.
