to beautify the house is even easier because the space allows designing many types of
vertical gardens suitable to the architecture of the house. This is also consistent with the

research results of Vu Thi Quyen & et al., (2021) with the topic "Research on creating
vertical green areas in architectural works".
6. Conclusion
The results of greenhouse planting activities show clearly on the production
capacity of the vertical garden model:
(1) More than 90% of survey respondents expressed the wish to adopt urban
gardens and more than 99% perceived the application of "vertical garden technology"
and "soilless culture" as an inevitable trend.

(2) Vegetable productivity per unit area of vertical farming is 122% - 204% higher
than that of vegetables grown in the field.
(3) Vertical farming's ability to absorb carbon dioxide per unit area is 1.5 - 2.7
times higher than vegetables grown in the field. This study also recorded "To get 1.0 kg
of biomass yield, plants need to absorb 1.6 kg of carbon dioxide and emit 1.0 kg of
oxygen into the environment".

(4) The results of this study show that planting vertical gardens saves 6 to 8 times
more water than traditional planting. At the same time, any nutrients and water not
absorbed by the roots can be recycled rather than lost to the system.
