The entire Garden project was divided into three phases.
The first phase of the project was the foundation. Welded stainless steel was used to isolate the ground of the enclosed area. The second phase of the project was mainly regarding the construction part of it. A six-grid steel skeleton would be supported by compression-resistant steel for the entire hemispherical artificial biosphere. As for the third phase of the project, the hemisphere would be equipped with double-layered special glass, where the outer layer would be coated with a special coating material to control the temperature.
There would also be biosphere B, C, D, etc. This would be to simulate other special outer-space environments, such as Mars. It could also be used for developing life support devices for people to use on other planets.
