VietNamNet Bridge – Many households in HCM City are planting organic vegetables and raising fish at home to supply themselves with food.

This model was invented by Mr. Nguyen Ngoc Khuyen, a farmer in District 12, HCM City. The model is suitable for installing on the rooftop.

This model is a miniature ecosystem. Waste water from the aquarium will be used to water vegetables. Vegetables will absorb the nutrients from the waste water to return the filtered water to the aquarium. This system runs automatically. The soil for planting vegetables is baked clay, containing micro-organisms to resolve organic substances.

Khuyen said that this system is easy to install, but to operate it well, the owner needs at least one month to practice. With just 20 m2, families can supply themselves with fresh vegetables on a daily basis.

It takes only 15 to 20 days to harvest vegetables.

The automatic pumping system is compact and consumes only 15 kWh of electricity per month.

A tank of 1 cubic meter is enough to breed 20-30 fish.

In addition to fish, this system is also suitable for crabs and freshwater shrimp.

The houses that do not have spacious rooftops can use vegetable towers, which require just 1 m2 of space.

Khuyen said he has installed nearly 1,000 similar systems in the city. The cost for a 20sq.m model is VND40 million ($2,000).
