Build one greenhouse. Here's a chance for cultivate the vegetable garden all year round, even during the coldest months. Common greenhouses are usually made of glass or plastic and require energy and money to heat. An interesting alternative could be represents from walipini, a greenhouse made underground capable of exploiting the light and heat of the Sun even in winter.
Walipini is a term of Indian origin, which recalls the meaning of "Place of warmth". The underground greenhouse was already designed 20 years ago to be able to cultivate even in the cold mountainous regions of South America. It is a method that allows farmers to maintain a productive vegetable garden throughout the year, even during the winter months.
Walipini's construction brought together the knowledge concerning buildings a passive solar heating and the construction of underground dwellings. By the nonprofit institute for the promotion ofsustainable agriculture a real manual arrives in America, based in Benson, illustrating the functioning of Walipini.
Walipini exploits natural resources for keep the heat stable and allow the production of vegetables throughout the year. It is important that there is the possibility of capturing the light and heat emanating from the sun. It is essentially about digging a ditch of shape rectangular, which will be protected by a transparent sheet and which will have to face in the direction of the position of the sun during the winter. One is then made special roof which allows the sun's rays to filter even in winter, heating the interior of the greenhouse and allowing plants to grow.
Furthermore, the underground greenhouse is able to exploit the heat retained by the ground. You need to take care of creating a ventilation system, irrigation and drainage. The realization of Walipini, including the purchase of the necessary materials, according to the Benson Institute has a cost of about 250-300 dollars. It is therefore a rather economical solution compared to common greenhouses, which does not require the use of diesel for heating and that adapts to areas of the world with the most rigid climate.
