Film Covering Natural Ventilation Single Span Sawtooth Plastic Film Greenhouse For Tropical Use

Greenhouse Introduction:

Type and structure of the plastic glasshouse
The condition of reception of light in the small arched shed is related to the type of old and new plastic film, degree of pollution, the number of trapped water drops and the type of shed and direction of extension of the shed.
Intensity of light: good performance of light transmission, usually light transmission in the small shed in spring is not less than 50% of the intensity of natural light.
Distribution of light: The closer to the film of spilling in the vertical direction, the stronger the light. Due to the small height and the small span of the shed, the internal distribution of light is relatively uniform.

Greenhouse Advantage:

Temperature: The temperature changes dramatically due to outside influences, and the temperature difference between the seasons and the day and night is large.
Under normal conditions, the temperature increase capacity of the small shed in winter and spring is only 3-6 $8451; and the temperature of the small shed covered with grass straw can be increased by more than 2'-8451;, and the capacity for temperature increase can reach 5-8'-8451;
In summer, the maximum temperature of the shed can be 15-20-C higher than the outdoors, which can cause high-temperature risks, so attention should be paid to ventilation and cooling.
Soil temperature: The soil temperature changes relatively uniformly, usually 5-6th C higher than that of open ground.

The water tightness of the plastic film is better, after the small arc shed is covered with the film, the water vapor is lost by the evaporation of the soil and the sweating of the crop is difficult to escape out of the shed, resulting in high humidity in the shed. In general, relative humidity in the shed can reach 70%-100%; At the same time, the evaporated water vapor accumulates in the warehouse film and flows along with the warehouse film to both sides, which often causes soil moisture on both sides to be very high, resulting in uneven distribution of soil moisture.
The humidity of the air in the small arch shed has a relatively large daily variation. Generally, relative humidity during the day is 40%60 and is superior to 90% at night.

Greenhouse Optional Systems:

We provide different greenhouse equipment to promote the efficient use of greenhouses. Such as cooling systems, irrigation systems, hydroponic systems, shading systems and ventilation systems. You can choose according to your weather condition.

Tunnel greenhouse advantages:

1.Tunnel greenhouse logs are the lowest cost and the easiest to build. The frame is the first structure of the tunnel greenhouse. It is a treasure, a door, a fortune, an arch, an end column and so on. It is only between 6-12 m in level. This benefit is in the maximum use of space, simple structure, strong life and long life. After all, it is very convenient to complicate, build and repeat. This wealth is the lowest, but the most affordable.

2.The tunnel is one of the simplest structures of the greenhouse wind gun. The film is 100% PE new with UV dependence. It is strong, long-lasting, protects the temperature and protects water, organizes plant growth, protects fruits and plants.

3..This greenhouse is simply installed, is framed by galvanized tubes. There is no proper column in the greenhouse, so the mechanics can enhance, place and use the lighting effects of operations and good work.
