Greenhouses and Greenhouse Plans
The original solar heated home, greenhouses allow us in the temperate zones to grow plants from the tropics, or to grow summer food crops all year long.
You can go the kit route for as little as $1500, or you can build the whole thing yourself from plans you can buy or
get for free on the web.
Some kits feature easy push-fit assembly, with bullet-proof plastic windows that can resist an 1100 pound snow load.
