Build a $300 underground greenhouse for year-round gardening (Video)
Growers in colder climates often utilize various approaches to extend the growing season or to give their crops a boost, whether it's coldframes, hoop houses or greenhouses. Greenhouses are usually glazed structures, but are typically expensive to construct and heat throughout the winter. A much more affordable and effective alternative to glass greenhouses is the walipini (an Aymara Indian word for a "place of warmth"), also known as an underground or pit greenhouse. First developed over 20 years ago for the cold mountainous regions of South America, this method allows growers to maintain a productive garden year-round, even in the coldest of climates. Here's a video tour of a walipini that shows what a basic version of this earth-sheltered solar greenhouse looks like inside: © Benson Institute It's a pretty intriguing set-up that combines the principles of passive solar heating with earth-sheltered building.

Off Grid World – Get Free Home Heating With an Attached Greenhouse Greenhouses are amazing for their traditional purpose – growing plants and extending the growing season in cold climates, but did you know a greenhouse can also be used to heat your home? A greenhouse attached to a home works as a passive solar heater by collecting solar energy during the day and transmitting heat into the home. Some homes are built with attached sunspaces, conservatories, or solariums, which are a similar idea, but are primarily intended as extra living space, whereas a greenhouse is intended for plant growing. Heat that is collected by the greenhouse during the day can be transferred into the house through windows or vents, or with fans for increased heat flow. At night, the windows or vents are closed to retain the heat in the house when temperatures drop outside.

$300 Underground Greenhouse Grows Food Year Round; An Extraordinary Walipini From vertical farms to solar-powered “farms from a box,” we’ve seen how farming technology has grown leaps and bounds in recent years. But for those who prefer something a little more rustic, growing food from a hole in the ground is as low-tech as you can get. A walipini, meaning “place of warmth” from the Amaraya Indian language, is an underground greenhouse with a transparent (usually plastic) covering that stays warm by passively soaking up the sun’s heat and absorbing the earth’s thermal energy. Fruits and vegetables can be grown year-round, making it ideal for communities in colder locations that can’t usually grow their own fresh and local produce during certain parts of the year. The farming method isn’t exactly new.

Does Your Community Need a Public Greenhouse? One of things my town has going for it is that it provides community gardens (not just sports fields).

Sustainability in the City: A Perspective on Food » Love & Wild Honey Love & Wild Honey What does it mean to be sustainable in an urban environment? Let’s start by defining what we mean by sustainable for this purpose, so we are all on the same page. From an etymological stand point, the word sustainability is derived from the Latin sustinere; to hold. Using the root of this word as a baseline, I think it is important to define sustainability as the ability to “uphold” something. In this case, we are looking at sustainability in food systems in the city. The World Bank does a beautiful job at putting this idea into more eloquent wording.
