Subject: Limitations of hydroponic systems....

It seems to me that the whole theory/practice behind hydroponics would allow
any kind of environment to be reproduced at will.  Case in point: Biosphere2.

I remember reading recently that it is impractical to raise grains (wheat,
rice, etc.) in a greenhouse environment because the plants are too finicky.
Then again, there is the question: Why would you _want_ to do this if
you have Kansas....

Which leads to my question.  Is there anything inherently difficult about
raising grains that would prevent such a greenhouse effort?  Does the 
greenhouse/hydroponic approach give any benefit that isn't being investigated?

Hope this isn't _too_ vague.....
