you can get lot of ideas in "youtube" itself, for terrace garden , you can start growing all type of vegitables for yourself first, you can think of comercial later..
I am looking for small farm land 1-4 acre with resonable rate between 4 lac/acre to 7 lac/acre, depend on the land , Wether developed or not does't matter, Water availability should be there,should be sutable for trees and vegetable cultivation.
Thanks
