1. What's Single-Span Film Greenhouse?

Film greenhouse is a structure with walls and roof made of film in which plants requiring regulated climatic conditions are grown. The greenhouse is high tech production facilities for vegetables or flowers. The greenhouse is 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 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.


2. Merits of Single-Span Film Greenhouse

* Hot dip galvanized frame
This kind of special treated steel has good anti-corrosion and anti-rust effects, which extend the service life of the greenhouse. Special designed structure and accessories make sure the outstanding performance of the greenhouse.

*  High quality covering material
With more than 80% light transmission and low cost, PE is one of the best material to be widely used in the greenhouse.

*  Fast installation
It's assembled structure, easy to be built and removed.

3.Hydroponics Nutrient Film Technique,NFT Deep Flow Technique,DFT Floating Capillary Hydroponics,FCH

Shading System

The main function of the system is shading and cooling in summer and making sunshine diffuse in greenhouse and
preventing crops from strong light. It can reduce internal heat accumulation of greenhouse effectively. Generally, it can
reduce greenhouse temperature from4ºC to 6ºC.

Cooling system
Use evaporation cooling principle of water to realize cooling. There is a specially-made cooling pad wall. When the air
penetrates wet curtain medium, it conducts heat exchange with vapor on moist medium surface so as to realize
humidification and cooling for the air.
