Hi,
The thing is, plants don't need organic "food". They just need carbon (mostly from CO2), nitrogen (from the atmosphere, but needs to be "fixed" by lightning or bacteria), trace minerals from the soil. And, of course, photons -- lots of photons.
I do remember reading about one hydroponics "farm" somewhere (location escapes me, might have been Chicago). IIRC, the only organic thing that came in was seeds. The rest was supplied by an aqueous solution they mixed with their chemistry sets. They were bragging about yield, freedom of sprays, lack of insects, etc. etc. Unfortunately, I can't give you a reference. It was some time ago and probably in some doctor's waiting room :)
I Googled hydroponics and got a bazillion hits. Just grabbed one off the top of the list http://www.hydroponics.com/index.html and found out some interesting things. Looks like if you have seeds, a rock crusher, some chemical ability and a lot of energy to convert to light you don't need much else.
Which, of course, brings up the question of why they were eating slime in the first movie.

How big was the aquarium in Noah's ark?
