How to build an underground greenhouse that you can grow in all year-round
DIY Underground Greenhouse - #OccupyTesla
In Ground Greenhouses have many benefits; the surrounding Earth provides excellent insulation, it's not an eyesore on the surface and most of all protecting plants from frost. Links to learning below.
The underground greenhouse method allows for natural insulation, while optimizing solar absorbance. These partially subterranean greenhouses appear to be the best for growing winter horticultural crops, and have been adopted in numerous countries, such as Japan, Russia, Korea, and now even the United States. These underground greenhouses can be something built very small for an individual or family, or it can be much larger to accommodate for more commercial needs. But it has proven to be more beneficial for growers than conventional methods which are at the mercy of varying weather conditions. Cheaper than aquaponics, but more effort than urban homesteading, an underground greenhouse is almost universally viable, more than affordable, and ecologically smart.

Oehlers method utilizes a coldsink to help keep warmer while Greigers plan utilizes insulation between bags and earth. All 3 plans utilize a form of thermal mass to retain warmth.
