Regarding food growing, I sort of expect that on either Mars or the Moon you would end up using solar panels to feed grow lights. You lose power via solar cell inefficiency but you make some of that back by shifting the spectrum of the light you emit into the wavelengths plants can absorb most easily. It's a hassle, but potentially less so than all the dangers your plants could be running into above ground.
And I figure the only viable colonization sites on the moon are the north and south poles, where you can get solar power continuously.

Why not use an orbital mirror that reflects only the wavelengths desired?
The idea is that you want to keep your plants away from the radiation, low pressure, and micrometeorites on the surface.
