What a conincidence, I just stumled on this while reading some totally
unrelated stuff:

Square Roots is an urban indoor farming company that was started by a
guy named Kimbal Musk. You might have heard about his brother Elon :-)



I thought everyone knew this? ;-)

Yeah, his brother has been promoting this tech for quite a few years
now. Paired with renewable energy, this technique allows you to grow
fresh produce using a minimal amount of land, water, and power. Perfect
for an urban setting and likely easily adapted for use on Mars.

Even though lots of artists renderings show transparent greenhouses on
Mars, it's likely more efficient to just put the "greenhouse" in a
regular, opaque, pressure vessel (could be rigid or an inflatable) and
use LED lighting. The LED lighting is easier to control the intensity,
wavelengths, and etc. than relying on outside light from a sun that's
further away and might be obscured by dust storms.

But to certain members of our society, growning certain plants indoors
using efficient LED grow lights isn't anything new. ;-)
