About Greenhouses



A Greenhouse is an enclosed frame or structure whose walls and ceiling are generally comprised of clear glass or various types of clear plastic to allow sunlight in, and attempt to keep cold out. Not all Greenhouses are 100% clear. Some are clear only where the angle of the sun will enter.

In recent decades the name for these glassed, clear structures is Greenhouse, however in previous times these clear structures were called Hothouse, Glasshouse, or even Sunhouse, and especially depending upon which part of the world you live in. In the past 30 years most areas of the world refer to them as a Greenhouse.

The shapes and sizes of Greenhouses are not consistent. They can be any size, from small shed like structures to large warehouse type structures. It all depends on their use and proposed growing capacity. The height can vary from 6' (2 m) up to 12' (4m), or even 24' (8m) depending on crop types and circulation needs. There is no standard size or height for a Greenhouse.

To keep snow and ice from accumulating, most Greenhouses have a slanted, or pitched roof similar to a standard home. Others may have an arched, or rounded top. It is believed that the arched Greenhouse may be more resistant to winds, and certainly the winds and snow should be considered when designing and constructing.

A Greenhouse can have many purposes. Some only use a Greenhouse as a sun room or workshop for the early preparation of plants and seedlings in the spring. The enclosed structure stops wind, and also provides a warmer working environment in early spring and late fall.

Extend The Growing Season
Some believe the earliest use of Greenhouses (hothouses) was for seedling preparation, however for the past 30 or 40 years the greatest use of Greenhouses has been to actually grow the plants in the Greenhouse from start to finish and use the Greenhouse environment to extend the growing season an extra 3 or 4 months.

Year-Around Growing
The greatest interest in recent years has been to economically heat the Greenhouse and create warm gardens year-around, 365 days of the year. However, this is not easily accomplished. The cost of producing the heat from normal heat sources can make the heated greenhouse concept unrealistic.

So how can we "Grow in the snow" economically...?

Successful winter and year-around gardens can be accomplished more easily than people realize, but it cannot be accomplished with the traditional Greenhouse designs or materials.

Although some are using twin-wall glass, acrylic, and double layers of polyethylene films, these only add an R-value of about 2 and still requires an immense amount of energy to heat the Greenhouse, especially through the night.

The purpose of the
Project Snow Blossom Initiative is to teach and promote the new, inexpensive technologies that allow us to grow gardens and all types of food in a Greenhouse year-around, 365 days a year, with virtually no energy costs by using geo-solar, geo-air, geo-exchange, thermal mass, and geothermal technology.
