Introduction of Roof Vent Greenhouse
This type of greenhouse has roof vent on roof for natural ventilation. And manual or motorized roller can be added to the roof vent to control the open and close of the it.
It is suitable for temperate and subtropical regions with an average annual temperature of 20-40℃ and sufficient sunlight, especially for tropical regions with high temperatures and abundant rainfall throughout the year.
Advantages of Innovative Structure
Double-round-tube Column: Two φ42mm hot-dip galvanized round tubes are connected by hoop
clamps. Compared with traditional square-tube columns, the cost is
reduced by 20%, and the anti-deformation ability is increased by
15% under the same wind pressure test.
Lightweight Design: The overall weight is reduced by 18%, and the transportation and
installation efficiency is increased by 30%.
Intelligent Ventilation System: The linkage of the top electric window and the side wall film
rolling device realizes precise temperature control within ±2℃,
saving 35% more energy than traditional greenhouses.
Planting Recommendations
It is suitable for leafy vegetables (such as spinach and lettuce),
solanaceous fruits (such as tomatoes and peppers), berry fruits
(such as strawberries and blueberries), and ornamental flowers
(such as roses and hydrangeas), meeting the refined regulation and
control requirements of crops for temperature and humidity.
Applicable Climate Types
High-temperature and High-humidity Climates: For example, in tropical and subtropical regions, humidity and
temperature are reduced through ventilation to prevent crops from
getting moldy.
Areas with Abundant Rainfall: The sawtooth design allows for rapid drainage. The combination of
insect-proof netting and agricultural film prevents the
accumulation of rainwater and pest damage. Meanwhile, the drainage
gutters can collect rainwater for use during the dry season.
Areas with Strong Winds: The wind-resistant structural design (such as the hot-dip
galvanized steel pipe frame) ensures stability.
Regions with a Large Temperature Difference between Day and Night:
Open the windows during the day to dissipate heat and close them at
night to keep the heat in, maintaining an appropriate temperature
for the growth of crops.
Areas with Seasonal Drought: The rainwater collection system can store water resources during
the rainy season, relieving the irrigation pressure during the dry
season.
Typical Application Scenarios: Coastal areas with strong winds, areas with seasonal drought,
regions with both rainy and dry seasons, tropical areas with high
temperatures, etc.

FAQ:
Q: Are you a factory or a trading company?
A: We are a manufacturer with a factory covering an area of 2,000
square meters and various production equipments.
Q: What is the material of the main structure of your greenhouse?
How long can it be guaranteed to be used?
A: The main frame of our greenhouse is generally made of hot-dip
galvanized steel. This material has super corrosion resistance.
Under normal circumstances, with proper daily maintenance, its
service life can reach 15 - 20 years. It can resist common natural
disasters such as wind, rain, and snow pressure, providing a stable
growing environment for the crops in the greenhouse.
Q: Before placing a large order, we'd like to buy a sample
greenhouse to try it out first. Is that possible?
A: Yes. We can send you a small-scale greenhouse by LCL (Less than
Container Load) sea shipping.
Q: I have a piece of land and I want to grow some vegetables or
raise some fish, but I don't know what kind of greenhouse and what
size I need. Can you help me with the design?
A: Of course. You can tell us the size of your land, your expected
annual output of vegetables or fish, as well as the local climate
information. Based on these data, we can design the style, size and
price of the greenhouse for you. We'll also let you know
approximately how many workers are needed and how long it will take
