Minimum Growing Space

[Steve]

A vegetarian diet is tricky, you expend a lot of energy in growing and harvesting the food, which generally has a low calorific value. Alternatively, you can let animals do the harvesting and then eat them. I have a good book from the USA about "bio-intensive" high density growing, worth a look if you have limited space: http://www.growbiointensive.org , although I personally favour letting tasty animals do some of the work.
