The model has 5 floors, 3 floors are leaf vegetables, and 2 floors are fruits and vegetables. This system operates under a circulation mechanism . Each model will be installed with a large water bottle, with motor installation. After starting the motor, the water will automatically run to the top floor, when the water runs to 2/3 of the plastic pipe, the water system through the duct runs down to the next floor. When the water runs 5 floors, there will be a water pipe running to the original nutrition bottle.

The model of hydroponic vegetables is made by two students in a week, with completely recycled materials. When growing vegetables in hydroponic model, more raw materials such as rice husk, coconut fiber, wood pulp will be used.

The design model was originally designed in metal, but when installed in Thanh An, it was rusted due to the salty water vapor. Two students studied and designed with plastic tubes.'The plastic pipe model will last for 4-5 years, easy to transport and cheap. It suits the climate conditions here, tolerates salt, and vegetables are also better ' - Tu Trinh shared.
