Vertical Farming

Advantages of Vertical Farming

Year-round crop production; 1 indoor acre is equivalent to 4-6 outdoor acres or more, depending upon the crop (e.g., strawberries: 1 indoor acre = 30 outdoor acres)

No weather-related crop failures due to droughts, floods, pests

All VF food is grown organically: no herbicides, pesticides, or fertilizers

VF virtually eliminates agricultural runoff by recycling black water

VF greatly reduces the incidence of many infectious diseases that are acquired at the agricultural interface

VF converts black and gray water into potable water by collecting the water of

evapotranspiration

VF dramatically reduces fossil fuel use (no tractors, plows, shipping.)

Irrigation of crops uses 70 percent of the fresh water that we use. The excess agricultural runoff, contaminated with silt, pesticides, herbicides and fertilizers, is unfit for reuse.

For every indoor acre farmed, some 10 to 20 outdoor acres of farmland can return to their original ecological state (mostly hardwood forest).

One estimate for proof of concept: constructing a five-story farm, taking up one-eighth of a square city block, will cost $20 million to $30 million.

An actual indoor farm developed at Cornell University growing hydroponic lettuce was able to produce as many as 68 heads per square foot per year. At a retail price in New York of up to $2.50 a head for hydroponic lettuce, you can see how profitable this and other similar crops can be.

Money Quote I think we have a good way to reduce both world hunger and Global Warming by growing more trees. Too bad the Farmers want their Government checks other countries however are doing this.
