Polycarbonate greenhouse for tomato and cucumber is a structure with walls and roof made mainly of transparent material, such as polycarbonate sheet, in which plants requiring regulated climatic conditions are grown.

A more scientific definition is “a covered structure that protects the plants from extensive external climate conditions and diseases, creates optimal growth microenvironment, and offers a flexible solution for sustainable and efficient year-round cultivation.” A modern greenhouse operates as a system, therefore it is also referred to as controlled environment agriculture (CEA), controlled environment plant production system (CEPPS), or phytomation system.

Many polycarbonate greenhouse for tomato and cucumber are high tech production facilities for vegetables or flowers. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate the optimality-degrees and comfort ratio of greenhouse micro-climate (i.e., air temperature, relative humidity, and vapor pressure deficit) in order to reduce production risk prior to cultivation of a specific crop.

Polycarbonate greenhouse for tomato and cucumber is a kind of greenhouse with a strong structure, beautiful appearance, and long lifetime. The mainframe adopts hot galvanized steel to enhance the stability of the greenhouse, which consists of a herringbone beam, Venlo type roof, gutter, main column, auxiliary column, girt, connected by screws, bolts, or suitable connectors. The cover material is adopted as the polycarbonate sheet, which is light but durable. The two sides and roofs usually install the side window system to ensure the ventilation of the greenhouse.

Advantage of polycarbonate greenhouse for tomato and cucumber

1.Light Transmission of PC sheet can reach to 89%.
2.Impact strength of the PC sheet is 250-300 times of common glass.
3.Light weight: save the cost of transportation, unloading, installing, and support framework.
4.The flame retardant is B1level.
5.Energy saving: keep cool in summer, preserve heat in winter.
6.Prevent dewing: when indoor relative humidity is under 80%, the inner surface of the material does not condensation. Dew will run off along the plate surface, not dripping.
7.As the PC sheet lightweight, tensile strength, through a simple steel structure, can meet the wind and snow requirements, and long life, beautiful appearance, to reduce duplication of construction and investment.
