Dvorák composed four piano trios, and all of them are fine works. The very last, the so-called "Dumky" Trio, has eclipsed the others in popularity, which is a pity, particularly with respect to the Trio No. 3 in F minor. This work, composed at exactly the same time as the Seventh Symphony, is clearly the finest work of its type since Beethoven--and that includes the three trios of Brahms. Perfectly proportioned, emotionally intense, and chock full of incredible tunes, it grabs you from the first note and never lets you go. The Beaux Arts Trio performs all of this music with their customary musicality and expertise, and the "twofer" price in unbeatable. Now try that Trio No. 3--you'll be glad you did. --David Hurwitz

How to Build Your Own Greenhouse
For avid gardeners, the biggest downside of the hobby is the limited growing season in much of the country. Gardening during the winter is often reduced to tending houseplants and browsing seed catalogs for next summerâ??s tomato choices.Master Gardener and builder Roger Marshall enthusiastically presents his case for home greenhouses with a thorough examination of everything the potential builder needs to know. Marshallâ??s coverage of the subject begins with a careful consideration of the various purposes served by greenhouses. Will the structure be used as a damp, warm hothouse for rare orchids? A tropical paradise for banana and citrus trees? A friendlier environment in which to get a jump on a summer vegetable garden is the goal for many gardeners, while an inviting setting for a year-round hot tub surrounded by lush greenery has an undeniable appeal. Whatever its eventual use will be, Marshall helps the reader examine every option and make an informed choice.
After determining the type and style of the structure, Marshall progresses, chapter by chapter, through the construction elements of the greenhouse â?? from choosing a site, to laying the foundation and determining which glazing material will work best. Plumbing, heating, supplemental lighting, misting, and automatic venting systems are also covered for the truly committed reader/gardener.
The final section of the book includes detailed plans for nine actual greenhouses, from a simple cold frame to an elaborately detailed framed, detached structure. Whatever the greenhouse goal, Marshall opens the way to longer growing seasons, abundant organically grown fruits and vegetables, and many more happy months playing in the dirt!

Greenhouse - Wikipedia, the free encyclopedia
From Wikipedia, the free encyclopedia
A greenhouse (also called a glasshouse) is a building where plants are grown.
A greenhouse is a structure with a different types of covering materials, like glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible solar radiation from the sun is absorbed by plants, soil, and other things inside the building. Glass is transparent to this radiation. The warmed structures and plants inside the greenhouse re-radiate this energy in the infra-red, to which glass is partly opaque, and that energy is trapped inside the glasshouse. Although there is some heat loss due to conduction, there is a net increase in energy (and therefore temperature) inside the greenhouse. Air warmed by the heat from hot interior surfaces is retained in the building by the roof and wall. These structures range in size from small sheds to very large buildings.
Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are PEfilm and multiwall sheet in PC or PMMA. Commercial glass greenhouses are often high tech production facilities for vegetables or flowers. The glass greenhouses are filled with equipment like screening installations, heating, cooling, lighting and may be automatically controlled by a computer.
The glass used for a greenhouse works as a barrier to air flow, and its effect is to trap energy within the greenhouse, which heats both the plants and the ground inside it. This warms the air near the ground, and this air is prevented from rising and flowing away. This can be demonstrated by opening a small window near the roof of a greenhouse: the temperature drops considerably. This principle is the basis of the autovent automatic cooling system. A miniature greenhouse is known as a cold frame.
Greenhouses protect crops from too much heat or cold, shield plants from dust storms and blizzards, and help to keep out pests. Light and temperature control allows greenhouses to turn inarable land into arable land, thereby improving food production in marginal environments.
Because greenhouses allow certain crops to be grown throughout the year, greenhouses are increasingly important in the food supply of high latitude countries. One of the largest greenhouse complexes in the world is in Almeria, Spain, where greenhouses cover almost 50,000 acres (200 km2). Sometimes called the sea of plastics.
Greenhouses are often used for growing flowers, vegetables, fruits, and tobacco plants. Bumblebees are the pollinators of choice for most greenhouse pollination, although other types of bees have been used, as well as artificial pollination. Hydroponics can be used in greenhouses as well to make the most use of the interior space.
Besides tobacco, many vegetables and flowers are grown in greenhouses in late winter and early spring, and then transplanted outside as the weather warms. Started plants are usually available for gardeners in farmers' markets at transplanting time. Special greenhouse varieties of certain crops such as tomatoes are generally used for commercial production.
The closed environment of a greenhouse has its own unique requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Significant inputs of heat and light may be required, particularly with winter production of warm-weather vegetables.
Because the temperature and humidity of greenhouses must be constantly monitored to ensure optimal conditions, a wireless sensor network can be used to gather data remotely. The data is transmitted to a control location and used to control heating, cooling, and irrigation systems.[1]
The idea of growing plants in environmentally controlled areas has existed since Roman times. The Roman emperor Tiberius ate a cucumber-like[2] vegetable daily. The Roman gardeners used artificial methods (similar to the greenhouse system) of growing to have it available for his table every day of the year. Cucumbers were planted in wheeled carts which were put in the sun daily, then taken inside to keep them warm at night.[3] The cucumbers were stored under frames or in cucumber houses glazed with either oiled cloth known as "specularia" or with sheets of selenite (a.k.a. lapis specularis), according to the description by Pliny the Elder.[4]
The first modern greenhouses were built in Italy in the 13th century[5] to house the exotic plants that explorers brought back from the tropics. They were originally called giardini botanici (botanical gardens). The concept of greenhouses soon spread to the Netherlands and then England, along with the plants. Some of these early attempts required enormous amounts of work to close up at night or to winterize. There were serious problems with providing adequate and balanced heat in these early greenhouses. Today the Netherlands has many of the largest greenhouses in the world, some of them so vast that they are able to produce millions of vegetables every year.
The French botanist Charles Lucien Bonaparte is often credited with building the first practical modern greenhouse in Leiden, Holland to grow medicinal tropical plants.[citation needed]
Originally on the estates of the rich, with the growth of the science of botany, greenhouses spread to the universities. The French called their first greenhouses orangeries, since they were used to protect orange trees from freezing. As pineapples became popular pineries, or pineapple pits, were built. Experimentation with the design of greenhouses continued during the Seventeenth Century in Europe as technology produced better glass and construction techniques improved. The greenhouse at the Palace of Versailles was an example of their size and elaborateness; it was more than 500 feet long, 42 feet wide, and 45 feet high.
In the nineteenth Century the largest greenhouses were built. The conservatory at Kew Gardens in England is a prime example of the Victorian greenhouse. Although intended for both horticultural and non-horticultural exhibition these included London's Crystal Palace, the New York Crystal Palace and Munich’s Glaspalast. Joseph Paxton, who had experimented with glass and iron in the creation of large greenhouses as the head gardener at Chatsworth, in Derbyshire, working for the Duke of Devonshire, designed and built the first, London's Crystal Palace. A major architectural achievement in monumental greenhouse building were the Royal Greenhouses of Laeken (1874–1895) for King Leopold II of Belgium.
In Japan, the first greenhouse was built in 1880 by Samuel Cocking, a British merchant who exported herbs.
In the Twentieth Century the geodesic dome was added to the many types of greenhouses. A notable example is the Eden Project, in Cornwall.
Greenhouse structures adapted in the 1960s when wider sheets of polyethylene film became widely available. Hoop houses were made by several companies and were also frequently made by the growers themselves. Constructed of aluminium extrusions, special galvanized steel tubing, or even just lengths of steel or PVC water pipe, construction costs were greatly reduced. This meant many more greenhouses on smaller farms and garden centers. Polyethylene film durability increased greatly when more effective inhibitors were developed and added in the 1970s. These UV inhibitors extended the usable life of the film from one or two years up to 3 and eventually 4 or more years. Gutter connected greenhouses became more prevalent in the 1980s and 1990s. These greenhouses have two or more bays connected by a common wall, or row of support posts. Heating inputs were reduced as the ratio of floor area to roof area was increased substantially. Gutter connected greenhouses are now commonly used both in production and in situations where plants are grown and sold to the public as well. Gutter connected greenhouses are commonly covered with a double layer of polyethylene film with air blown between to provide increased heating efficiencies, or structured polycarbonate materials.
The Netherlands has some of the largest greenhouses in the world. Such is the scale of food production in the country that in 2000 greenhouses occupied 10,526 hectares, or 0.25% of the total land area of the Netherlands.[6]
Greenhouses began to be built in the Westland area of the Netherlands in the mid-nineteenth century. The addition of sand to bogs and clay soil created fertile soil for agriculture, and around 1850 grapes were grown in the first greenhouses, simple glass constructions with one of the sides consisting of solid wall. Around 1900 greenhouses began to be constructed of nothing but glass, and they began to be heated. This also allowed for the production of fruits and vegetables that did not ordinarily grow in the area. Today the Westland and the area around Aalsmeer have the highest concentration of greenhouse agriculture in the world. The Westland produces mostly vegetables, besides plants and flowers; Aalsmeer is noted mainly for the production of flowers and potted plants. Since the twentieth century, the area around Venlo (in Limburg) and parts of Drenthe have also become important regions for greenhouse agriculture.
Since 2000, technical innovations include the "closed greenhouse", a completely closed system allowing the grower complete control over the growing process while using less energy. Floating greenhouses are used in watery areas of the country.
The Netherlands has around 9000 greenhouse enterprises that operate over 10,000 hectares of greenhouses and employ some 150,000 workers, efficiently producing E4.5 billion worth of vegetables, fruit, plants, and flowers, some 80% of which is exported.

Each greenhouse kit has unique features. The Solexx hobby greenhouses are the most popular greenhouse models. With their composite tube framing, they are the strongest of all the greenhouses and hold up extremely well in severe weather conditions. The greenhouse cover material is Solexx twin-wall polyethylene 3.5mm covering for good insulation. Solexx greenhouses also have the highest light diffusion. (Read more about the benefits of diffused light and how different greenhouse coverings transmit light). There are four different Solexx greenhouse models and many sizes to choose from. Each Solexx greenhouse kit includes built-in bench frames, so you can squeeze in all your plants and still have room to start more.
Sunshine greenhouse kits have a beautiful redwood frame and are the easiest of all the greenhouses to assemble and even include an assembly video. The smallest greenhouse can be assembled in just a few hours. The polycarbonate panels have an anti-drip coating to help minimize condensation in the greenhouse. The 6? wide Mt Hood greenhouse is perfect small greenhouse for gardeners with limited yard space.
Hobbyist greenhouses have a plastic resin frame that snaps together, so very few tools are needed for assembly. They are covered with polycarbonate greenhouse panels for added insulation from the frost. Choose from a white or green greenhouse frame. The white frame is highly recommended in hot climates to limit the expansion and contraction of the plastic frame.
The best value greenhouse is the Early Bloomer hobby greenhouse kit. With its sturdy composite frame, Solexx paneling and low price, there is no other insulated backyard greenhouse on the market that compares. One advantage is that you can pick it up, without any wobbling ? it is extremely solid, and move it to any location in your yard. Customers love this greenhouse as a starter greenhouse and for wintering-over plants.
The Enthusiast greenhouse has single wall polycarbonate greenhouse panels to let you grow a few extra weeks out of the year. The frame is a rust-proof combination of plastic and aluminum.
Our Early Start greenhouse is the least expensive of all the hobby greenhouse kits. It is a good hobby greenhouse to start with to test the waters. Since it has a polyethylene plastic greenhouse covering, it will have little or no insulation, but it still helps you hold off the frost in the late spring and the early fall. The hobby greenhouse has a sturdy reinforced aluminum frame.
Additional cold frame season extenders are available to help protect your garden from frost. From the double-walled Deluxe coldframe to the Frost Shield blankets, you can protect your plants from frost. We have frost protectors you can leave up year-round or reuse each season.
If you are looking for a do-it-yourself project, Solexx greenhouse covering makes it easy to design your own greenhouse. The twin-wall polyethylene is extremely strong and resistant to hail, wind and snow, yet it is also flexible allowing you to fit it all in one piece on your structure. You can even bend Solexx greenhouse covering around corners so you don?t need to add flashing. The greenhouse panels can be overlapped or joined with a flexible plastic H-Channel. Even though you can?t see through Solexx panels, your greenhouse plants still get plenty of sunlight - even tomato plants and peppers thrive. An advantage to the translucent greenhouse panels is that they provide highly diffused light. That means light finds its way to every part of the plant resulting is more vigorous plant growth in your hobby greenhouse.
In addition to our selection of greenhouse products, you will find all the greenhouse supplies and greenhouse accessories you need to keep your plants happy. Choose from our selection of greenhouse supplies: fans and vents, greenhouse heaters, grow lights, Radius ergonomic garden tools, shade cloth, flooring, tie down kits and seed heat mats. Explore our hydroponic products, containers, hand tools, books, greenhouse pest control, watering products, misting systems, potting benches, garden art, Soji solar garden lanterns, and bionic gardening gloves. These products are all carefully chosen and backed by a 90-day money back guarantee.
