Many people around the world have begun using greenhouses. In the days of old, the common construct was of glass and sometimes aluminium. With time and discovery in new plastics, people found glass to have many thermo genic deficiencies for their growing needs.
Polycarbonate greenhouses have become a common way to address residential and commercial growers’ greenhouse needs. They can be made for tropical growers because they can be made of white (opal) panels that help reflect the harmful ultraviolet rays and reduce the impact of these rays upon contact with the polycarbonate panels, thus reducing the need for additional shading. For seasonal, domestic plants, and vegetables, that need a more condensed heat, bronze panels can be used to achieve this effect. If a more direct sunlight and higher ultraviolet rays are needed in perhaps a cactus garden, or desert shrubbery and succulents, clear panels can be used that allow more of the direct impact of light.
The problem that was found with glass greenhouses is that, there was no durability. Glass easily cracks and breaks when met by sleet or ice especially true of the coldest UK months December-February. These temperature changes can also cause damage from expanding and contracting of glass. A polycarbonate greenhouse is virtually indestructible. The panels have an incredible two hundred and fifty times more resistance to impact than that of glass. The panels the greenhouse are made of, are a thermoplastic, which means it expands and contracts easier and keeps its shape. Unlike glass, it can be cold formed, or bent into shape without the use of extreme heat.
Since these greenhouses use materials that are so free forming they can be made into many geodesic and square like shapes. They can have thatched or flat panel roofs angled to dispatch water during the rain, and can have single wall or flat twin wall panels. The air is trapped between panels and creates an insulation to add to the heat benefit of these greenhouses. A variety of panels can be used to build the greenhouse as well. Four by eight sheets are usually the largest used, but smaller panes are available. The panels used can be one thirty second of an inch thick, all the way up to an inch of thickness. These panels are usually coated with some type of an ultraviolet protectant, and this is one more advantage of this type of greenhouse.
The savings of a polycarbonate greenhouse are truly incredible upwards of £2000 can be saved in one year on energy alone. When the cost of purchasing fruits and vegetables is compiled as well, there is little wonder why these greenhouses are becoming as common as a choice. Also, because of the even heat flow, and heat retention, vegetation can be grown for longer periods throughout the year. Even if the conditions become wet and humid outside, this type of greenhouse holds little to no moisture inside the structure.
One of the few drawbacks that a greenhouse of this type has is that the owner must be careful as to the cleaning material that is used. Wool or pads, as well as some paper towels can have abrasive particles. The panels with time can be scratched and loose some of their heat retaining properties. However, these greenhouses are very chemical resistant and can easily resist the effects of alcohol and ammonia over time. It is suggested to use rags made of one hundred percent cotton, or some type of a microfibre cloth when cleaning the interior and exterior of these greenhouses.
Polycarbonate greenhouses are also economical in that they can be dismantled piece by piece, and therefore allow the owner the freedom to move it in cases of housing or living changes.
Another advantage to a green house is protection of the plants or flowers from outside threats. The use of chemical pesticides is greatly reduced when owning a greenhouse because the threatening predator can quickly be contained and destroyed. For newly forming plants and buds, the violent thrashings of wind are also contained which means a hearty stem can be formed.
These greenhouses offer the benefit of controlled heating, the ease of transport, and the option to create a wide variety of shapes and sizes. They are found in use residentially and commercially throughout the UK and abroad. They are a refuge against the elements and predators, as well as offering durability and convenience allowing growers the ability to grow healthy and well grown plants and vegetables, and can easily last upwards of ten years, making them an economical choice for growers in all locals.
