Pit Greenhouses
Depending on latitude, but despite above ground air temperatures (and wind chill), 6 to 8 feet down into the earth, temperatures remain fairly constant, between 50 and 60°F. Meaning your pit greenhouse will be much warmer than an above ground greenhouse in winter and that cool earth will keep temps bearable in the summer.

Underground greenhouse. The inside can be cased in stone, mud brick or any dense natural material able to absorb large amounts of heat. Cool weather crops like lettuce, kale and brocolli can be grown during winter in harsh climates. The glazing creates a “greenhouse effect.” If your water table is high, obviously that could spell disaster. It is recommended you build your greenhouse at least five feet above the water table. growtest.org
Mike Oehler’s pit greenhouse design. Mike digs a deep trench for access on the shaded south side which also allows cold air to sink and be warmed by the deeper, warmer soil. Many install tubes within the soil to transfer warmed air into the earth, yet Mike believes you need only the cold sink to allow the transfer in most climates. How to: motherearthnews.com.

Called a walipini in South America (from the Aymara Indian language, meaning "place of warmth"). As you dig, save your upper most topsoil (for the new bottom) and use the deeper soil as the new berm on the north side (or south side if you're south of the equator). Angling your window 90 degrees to the sun on the winter solstice will allow the pit to store the most heat during those days when the sun shines the fewest hours. Benson Institute Building a Walipini: www.bensoninstitute.org
Earthbag pit greenhouse. During the day, the earth walls store heat, the walls are the battery that release their heat at night. A properly designed pit greenhouse is naturally warmed at night from five sides, in an above ground greenhouse, only one side, the floor is heated during the day. A waterproof barrier extending along the periphery and down the berms are necessary www.naturalbuildingblog.com

Here is a large walipini in LaPaz, Bolivia. At two minutes they go inside the walipini, at four minutes they walk around the outside. In Spanish. Obviously they do not get much rain there. Organic Farm in Upper de la Paz, Bolivia.
Pit greenhouse made of local stone in Nepal at almost 10,000 feet altitude, where the temperature falls below freezing 199 days per year. Inside lush vegetation: www.rids-nepal.org
This pit greenhouse in Mongolia is currently producing food during three seasons of the year. As the footprints show the entrance is on the opposite side. thegreenbackpack.blogspot.com
Inside of above pit greenhouse. In a cold climate, the north, east and west walls should be well insulated. The north ceiling should be well insulated as well. thegreenbackpack.blogspot.com
Greenhouse built into a hill in Tennesee. Lots more pictures here: www.wind-sun.com
This pit greenhouse is in Texas, it is essentially a hole dug into the ground. Here the soil was such hard sandstone, minimal wall support was necesary. How to here: taroandti.com
Earth sheltered greenhouse with earthbag walls in Patagonia. Note the use of plastic around the periphery: ourlittlething.ning.com
One might need to dig a shallow drainage ditch around the perimeter of the greenhouse which will lead the run off water away from the structure. darfieldearthship.com
Pit greenhouse. Oft times barrels of rainwater will be stored at the back of a greenhouse to soak up and store even more heat. Note the entrance way to right. Lots more photos: greenhouseglimpses.blogspot.com
Walipini is another name for a pit greenhouse, this one is topped with old windows. More photos: onepinkhippie.com
Pit greenhouse in New Mexico dug by hand! Step by step photos: coatinativesnursery.com
Mud brick walipini in Ladakh which produces food year round in a very harsh climate. More photos: ashdenawards.blogspot.com
Care must be taken waterproofing, draining and ventilating the greenhouse. The most efficient pit greenhouses face the windows south and use the north wall to store heat.
This amazing couple bought a house with an old gunite pool and turned it into a 'closed-loop food-producing urban greenhouse.' Supporting tilapia, chickens and hydroponic vegetables and fruits. Watch video here: gardenpool.org
Earthen walled pit greenhouse. Lots of natural clay to absorb heat. The two most important factors in a pit greenhouse are the large amount of thermal mass (stone, soil, water), and its positioning toward the sun. www.organica.net.pl
An easy way to warm up and bring light into your basement. Build a mini-pit greenhouse on the south side of your home. naturalbuildingblog.com

At the New AIchemy Institue bioshelter, fish tanks and compost heat the greenhouse and adjoining house. Water is dense and holds heat even better than rock, soil takes third place in heat storage. The solar aquaculture ponds are above-ground, translucent tanks. The fertile pond water was used for irrigating crops. community.theaquaponicsource.com

Straw bales are a great insulator (an R-value of 1.5 to 3 per inch). Manure below ground will also help to keep these plants warm. Photo by Terrie Schweitzer, www.flickr.com
