Drip irrigation can be done in home...
now a days the technologies have become new and more advancded.
i have done a project wid my frnds in my skl..
may be if it is for a small area or if u want to do a project then u can takes a rubber tube and make hols at equal distance and plant seeds at those places with holes and u can make sure it works properly..
and another thing what u can do is ask some one near by like some garners to make those by callin carpenters and that can be perfect thing.
but if u want it hand made follow the first one
