to answer the question: there's a few things i can eat around here that are greenhouse grown, but we need bigger investments into more mature production, and it won't happen so long as you can hire slaves from mexico at a tenth the cost. we'll just keep poisoning ourselves, instead.

but, don't trick yourself into thinking that only certain classes of produce are hydroponically available. it's not true. you can grow carrots & beets & avocados and really anything you want from a hydroponic system. large trees like oranges & bananas may need to undergo some artificial selection before they're ready for indoor breeding, but it's just a size issue.
