If you want to build a greenhouse, you should be careful planning, the final choice of the greenhouse will depend on the growing space desired, Home architecture, available sites, and costs.
Backyards, rooftops, crop production fields, from the Arctic Circle to the equator – almost every climate and environment can benefit from some kind of greenhouse Investor advisor. Controlling the environment in these greenhouses can mean more heat, more shade, supplemental lights, insect screens, etc. Lets look at some commonsense approaches and basic deciding factors one can use in site planning for a greenhouse:
Light Just as in planning a garden, greenhouse growers should be very aware of changing light patterns throughout the seasons. Even in an open field, one needs to be aware of orientation to the direction of sun. Intelligent site planning in a backyard can save a lot of energy and may allow growers the edge that will make their plants thrive.
Look for deciduous trees – cover from deciduous trees can give the much needed shading in the summer, which is probably the most difficult time of year to keep anything thriving in the average backyard greenhouse. Also, remember that the angle of light changes from winter to summer, as well as the rise to fall points on the horizon. This will help with orientation to other buildings, high fences, etc.
Foundation and site drainage – Consider the type of foundation on which the greenhouse will be installed and consider the drainage and elevation of the site. The drainage of the site is crucial. Always, factor in what foundation requirements are for each model and type of greenhouse.
Energy Input issues – Your greenhouse will need energy input to power fans, heaters, etc. Thinking out the distance from your power and water source is a very necessary first step in a friction free greenhouse building process…
Once your power is there, you will need it for a variety of environmental controls. Fans (both ventilation and circulation), motorized controls for vent windows, evaporative cooling pumps, heaters (if electric), etc.
Ventilation is probably the most important issue in a greenhouse, without it the greenhouse quickly turns into a solar oven in which no plant can survive. Ventilation in the greenhouse is maintained through passive vent windows on the sides and ridge of the greenhouse and/or through fans and shutters mounted on opposing ends of the greenhouse.
Are you interested in gardening year-round? Then shop for greenhouse kits which contain everything you need to build a greenhouse. While shopping you will discover that greenhouses have a fascinating history. While greenhouses might seem like a modern invention, growing plants in controlled environments dates back to ancient Rome. History books tell us that Tiberius, a Roman emperor, ate a vegetable every day that was similar to the modern cucumber.
In order for Tiberius to have this vegetable every day at his whim, Roman gardeners used artificial methods similar to today’s greenhouses. According to a description by Pliny the cucumbers were planted in carts, placed in the sun every day, and then brought inside for warmth. The food was stored in houses that were glazed with mica sheets.
The greenhouse was not modernized until pre-Renaissance Italy. Explorers brought exotic plants from the tropics and kept them indoors at night or for winterization. These early greenhouses were not adequate for providing balanced heat, but today’s greenhouses and greenhouse kits have none of these difficulties.
Early greenhouses have traditionally been seen as signs of wealth. However, as exploration into the fields of science and botany grew, greenhouses quickly flourished at universities. The French used greenhouses to keep oranges from freezing and as pineapples became popular they were tended to indoors. During the 17th century in Europe, greenhouses continued to grow in size as better glass construction techniques were found. In France, the Palace of Versailles had a greenhouse that was more than 500 feet long and over 40 feet high.
We associate the 19th century with large elaborate greenhouses of the Victorian era. Larger greenhouses were built in England, London, New York, and Munich.
Today’s greenhouses come in two varieties: glass and plastic. Commercial glass greenhouses utilize technology for mass production of vegetables and flowers. These greenhouses are filled with high-tech devices that heat, cool, and control lighting. The functionality may be so high-tech that is controlled by a computer.
Greenhouse kits are much simpler than these high tech devices. And you don’t have to know how the kits work, but most gardeners find it helpful to have a basic understanding of how greenhouses function.
Greenhouses use different transparencies of glass to work with thermal infrared radiation and solar radiation. While the glass allows most of the solar wavelengths to pass through it blocks the thermal wavelengths that the plants and soil inside the greenhouse give off. In other words, solar radiation is allowed to pass through from outside and heats the plants, vegetables, fruits etc. inside the greenhouse. The longer thermal wavelengths are trapped by the glass so they can I get out and the key keeps building up.
