Re: Greenhouses

Lots of good information in this Farming and the geography of nutrient production for human use: a transdisciplinary analysis

The variety of crops and of livestock as well as fish biomes but not how much land or energy for each are required. Lest we forget we have hugh biomes of forest and oceans with which we would not live with as well.

So data from FOOD, LAND, POPULATION and the U.S. ECONOMY

Lets call it 2 acres and that converts to 8093.71 m^2 for just 1 person....or 90 meters on a side...

The Greenhouse Calculator provides useful equations and data for people who work with greenhouses and high-tunnels.  This includes basics for greenhouse construction and heating, for mulching and coverage with straw and for greenhouse planters.
