Vegetable Growing In Solar Greenhouse Traditional Vs
   
VEGETABLE GROWING IN THE SOLAR GREENHOUSE
Check out Solar Greenhouse Construction
There's a lot to be learned about cool greenhouse vegetable culture. The most important trick we've discovered is using the right growing container. Traditional greenhouse wisdom recommends pots on waist-high benches — easy to reach and easy to isolate diseases and pests. But continuous temperature recordings in the soil pots showed that the temperature in the root zone changed right along with the air temperature, because the exposed surface of a pot is so large. There were large swings every day, extremes that plant roots aren't used to. So we switched to two large beds 18 inches deep that cover the greenhouse floor. They held the root zone to a 10-degree daily change which is natural, and also made a greater heat-storing mass.
Beds have many other advantages. Roots have more room to forage for water and nutrients. The environment becomes a better one for natural predators like spiders. Because the soil in beds holds a large amount of organic matter, they also become an important source of carbon dioxide. Plants in a sunny, airtight greenhouse can use up all the available carbon dioxide in a few hours.
In the far North, where solar greenhouses will be the most expensive to build, they will yield the greatest expansion of the gardening season. Properly made and maintained, a solar greenhouse should outlast its builder. The materials are all durable or renewable.
House-attached greenhouses are even cheaper to build. As you plan your solar greenhouse, you should think first of this kind for many reasons. Attached greenhouses have about a third less surface area for the same floor space as a freestanding one. Thus construction costs are lower, and less heat is lost at night. Attached solar greenhouses are the most efficient hot-air solar collectors known. High and low vents that open into the home through the common wall exchange solar-heated greenhouse air for cool air at floor level from the house. At night, the house can return some of the heat to the greenhouse. All the design principles for solar greenhouses apply to the attached greenhouse, except they may need less heat storage. The only requirement is a suitable spot facing south that is unshaded in winter.
Looking only at the money, it's obvious that a durable solar greenhouse, attached or freestanding, will repay its cost. Compared to conventional all-glass models the fuel savings alone will pay for its construction in three to four years in the North. And they make you independent of an unhealthy agriculture and the transportation system it depends upon for fresh vegetables to tide you through winter. That's why we recommend so strongly that you build one if you can.
