...at least enough so we don't have a scurvy problem.

As we are in the process of starting to populate out basic hull design with its required systems, attention must also turn to some of the less sexy aspects, such as stores and provisioning. Maintaining sufficient perishable stores aboard to feed 400 warm bodies for six months, not to mention the additional 6 month reserve, will be no mean feat, even taking into account the capacities of frozen, tinned, and dried stores. In which case, is it worth considering space for some capacity to cultivate food aboard through a hydroponic system. While it may not be feasible (or even sensible) to rely on such a system for all meal requirements, it may be enough to ensure the occasional fresh lettuce leaf or tomato arrives on the crew's plates.

Of course, hydroponics will use of volume, mass, and power. However, if people think it worthwhile, it might be worth conducting some study into how hydroponic yield over time would match up against the volume, mass, and power requirements for storing an equivalent amount of provision over that same period.
