Water and land have been scarce nowadays and the needs for much efficient use of this resources is much important than before
especially with the growing population and climate change. The condition is worsened with the global issue which is Covid-19 that
has decapitated many of economic activities. Due to this, government has been enforcing strict regulations. The planting of crops
especially short-term crop at home is much more relevant than before as there are nothing much that can be done. Combine that
with the unutilized source of rainwater, thus come the concept home farming. Brassica Juncea are chosen due to the short life cycle
thus would make it easier to cultivate. It is irrigated with water from rain via homemade reservoir thus ensuring no cost at the water
side. The needs for much more efficient irrigation method such as utilization of rainwater to create energy can be feasible as there
are downward movement of water from the topside of house downwards.
