Space Food From Space Farms 168
Modern Farmer magazine has an article about NASA's efforts into growing food in space, a slow, difficult process that's nonetheless necessary if humanity is to have any significant presence away from Earth's surface. Quoting:
"This December, NASA plans to launch a set of Kevlar pillow-packs, filled with a material akin to kitty litter, functioning as planters for six romaine lettuce plants. The burgundy-hued lettuce (NASA favors the 'Outredgeous' strain) will be grown under bright-pink LED lights, ready to harvest after just 28 days. NASA has a long history of testing plant growth in space, but the goals have been largely academic. Experiments have included figuring out the effects of zero-gravity on plant growth, testing quick-grow sprouts on shuttle missions and assessing the viability of different kinds of artificial light. But [the Vegetable Production System] is NASA's first attempt to grow produce that could actually sustain space travelers. Naturally, the dream is to create a regenerative growth system, so food could be continually grown on the space station — or, potentially, on moon colonies or Mars. ... Plant size is a vital calculation in determining what to grow on the space station, where every square foot is carefully allotted. Harvest time is also of extreme importance; the program wants to maximize growth cycles within each crew’s (on average) six-month stay."

I think it's a waste of time trying to solve issues of maintaining a biosphere in space, when a push into space will be much easier after we've reached the Singularity: machine bodies don't need food, air or water.

Not yet. Eventually, yes. They could grow basil onboard the station. Basil respirates all night (baby) and it's edible and has a ton of health benefits, so it's a logical choice.
However, it makes less than no sense to grow in a soil-like medium. They should be using aeroponics. Growing in any solid medium at all is just fucking stupid, because it's unnecessary mass.
