i was watching an old episode of Star Trek: Voyager, and saw their hydroponics garden in the ships cargo bay. This got me to look at gardens from a different perspective.
my sketch is of a hydroponics garden where all the plants are grown in special containers, with nutrient solutions instead of soil, and electronically controlled custom atmospheres for each plant. this could be on a spaceship, or a new colony on some other planet, or an underground bunker in a post nuclear holocaust earth... or in some agrophobic gardener's basement.
some interesting hydroponics links i found:
