Consider this. You can build a "High Tunnel Greenhouse" with 1000 feet of area, 12 feet tall, and 30 feet wide and 40 feet long for about $2780.

THIS COULD BE YOUR GARDEN!
You can grow enough food for your family organically, and have food left over to give or sell to others. You can power your water well, with a wind turbine, and never pay an electric bill. People are quietly doing this by the thousands, across the world.
High tunnels are inexpensive “green houses” that can be utilized by agricultural producers to grow food crops in high volume. It is an answer to the rising cost of land, an answer to the rising cost of water, and an answer for a need to move food production nearer to metropolitan areas therefore lowering expensive transportation. But more and more people, who want to preserve the environment, have fresh food, and enjoy organic foods are using high tunnels. Even churches, schools and cities are sponsoring "garden projects".
Advantages also include:
1. Ability to control humidity
2. Ability to control water, especially through drip irrigation
3. Ability to control fertilizers, insects and temperature
4. Ability to grow three crops per year, or increase production of one or two crops by 200%
5. Ability to control temperature for optimal growth
One ideal application of High Tunnel production is the small 30 by 40 feet tunnel shown in the photo in this article. This tunnel is watered by a well, with an electric submersible pump, with electricity provided by a wind turbine. This “green house” is within the city limits of Fort Worth, Texas. ..cont'd
