At home in a dome.

The only
way this would work is by filling spheres half full of local soil
and burying them half-way down. Then it would look like a dome.

Why throw away 50% of the useful volume ?

I still do not see any advantages of domes.

Even if we wanted a greenhouse dome, all we need are some shallow trays of dirt in the middle, we do not need to fill the entire lower half with soil.

And trays of custom hydroponic fluids (nutrient rich water) would be more useful than sterile Martian soil.
