We don't need either of those things.

Earth exists in space just fine without those technologies - and so
all we need to do, even if it's less efficient, is to duplicate Earth
in space.

We can't live in vacuum ourselves, and if we need air for ourselves,
why can't we also put our plants within the air?

As for radiation, we can get rock from the Moon or the asteroids until
we have as much shielding around us in space as the Earth's atmosphere
provides us on Earth.
