What is a Greenhouse?
A greenhouse is a structure designed to create an ideal environment for growing plants. It is typically made of transparent materials such as glass or plastic that allow sunlight to enter while retaining heat, thus creating a warm, stable climate inside.
This controlled environment helps extend the growing season, protect plants from adverse weather conditions, and can be adjusted to suit the needs of different plant species. Greenhouses can vary in size from small backyard structures to large commercial operations. They are commonly used in agriculture, horticulture, and gardening to cultivate vegetables, flowers, fruits, and other plants year-round.
Chapter 2
The Evolution of Greenhouses: A Historical Timeline
- 14-18th Century – In Europe, “giardini botanici” emerged in Italy. These early botanical gardens often included structures to protect exotic plants from harsher weather.
- 1619 – The Hortus Botanicus of Leiden, Netherlands, is built.
- 1680s – Greenhouses appeared in the Versailles, France.
- 1800s – The popularity of greenhouses increased among the wealthy in Europe and the United States. These were often elaborate structures made of glass and iron.
- Mid-1900s – The introduction of polyethylene film (plastic) revolutionized greenhouse construction, making them more affordable and accessible.
- Late 1900s – Development of environmental control systems (heating, cooling, ventilation) to optimize growing conditions.
- 2000s-Present – Growing adoption of advanced technologies such as hydroponics, LED lighting, and automated systems in commercial greenhouses.

Chapter 7
Do greenhouse structures rust or corrode?
Generally speaking, at CFGET, we prioritize the use of hot-dip galvanized steel for greenhouse structures. The environmental conditions in different regions, such as high-temperature and high-humidity areas or extremely arid regions, require different specifications for the galvanized coating. Therefore, we select the appropriate galvanizing index based on local climate characteristics.
Typically, we use a galvanizing index between 70 and 150 to ensure that the structural frame material can resist rust for approximately 20 years. In special cases, we can customize the rust-resistant lifespan, which can extend up to 30 years. However, it is important to note that in environments with chemical gas corrosion, the service life of the galvanized coating will be shortened accordingly.
Zinc Coating Thickness Reference (ISO 1461, ASTM A123, EN 10346):
For different application environments, the thickness of the hot-dip galvanized coating is usually set according to specific corrosion conditions. The standard range of zinc coating thickness is generally between 50 μm (microns) and 200 μm. The specific thickness is chosen based on the customer’s requirements and the intended service life.
* General use: 60-80 μm
* Harsh environments or higher corrosion resistance: 100-150 μm
* Extreme environments (e.g., chemical plants): Above 200 μm
Common International Units:
* Micrometers (μm): Usually used to describe the thickness of the galvanized coating. 1 μm = 0.001 millimeters.
* Inches (in) or Mils: In some countries, particularly the United States, the zinc coating thickness may also be measured in mils. 1 mil = 0.001 inches.

Supermarkets and restaurants provide stable demand but require consistent quality and supply. E-commerce and community group buying platforms allow direct-to-consumer sales with higher margins. Additionally, food processing companies purchase raw agricultural products for further production, and the export market offers opportunities for premium produce but requires compliance with regulations.
To establish a strong market presence, farmers can use brand marketing to enhance product value and attract premium buyers. Contract farming with businesses ensures predictable sales and stable pricing. Engaging in B2B partnerships with restaurants and food processing companies secures long-term demand, reducing reliance on fluctuating retail markets.
07.What Are the Profit Models for Greenhouse Farming?
Greenhouse farming offers both traditional and innovative profit models. The traditional approach includes selling produce through wholesale markets, which provide bulk sales but lower margins. Direct supply to supermarkets and restaurants ensures stable demand and pricing. Retail sales at farmers’ markets allow for higher prices but require more effort in distribution and marketing.
Innovative models can further increase profitability. Pick-your-own farms and agritourism attract consumers willing to pay for an experience. Contract farming secures guaranteed sales with businesses. Organic certification adds value by appealing to premium markets. Processing agricultural products, such as dried fruits or juices, extends shelf life and enhances marketability, offering higher returns compared to raw produce.
08. How to Apply for Government Subsidies or Agricultural Investment Support?
Government support for greenhouse farming comes in different forms. Facility subsidies cover greenhouse construction and water-saving irrigation. Low-interest agricultural loans provide financial assistance for farming projects. Technology grants support investments in smart greenhouses and sustainable agriculture.
The application process involves checking eligibility, preparing necessary documents, submitting the application, and undergoing site inspection before funds are disbursed. Farmers should consult local agricultural departments for specific requirements and timelines.
09.Is Investing in a Smart Greenhouse Worth It?
Smart greenhouses use advanced technologies such as automated irrigation, environmental monitoring, AI-driven crop management, and remote control systems to improve efficiency.
Although initial investment costs are high, smart greenhouses offer long-term benefits through optimized resource use, reduced labor dependency, and higher yields. They are ideal for large-scale farming operations where automation can significantly enhance profitability.
10.What Are the Key Factors in Greenhouse Construction?
Location selection is critical, considering factors like climate (water supply, electricity, sunlight), transportation (proximity to markets), and land policies to ensure compliance with agricultural regulations.
The greenhouse structure should be designed for wind and snow resistance, proper ventilation and insulation, and scalability for future expansion. Choosing the right materials and layout ensures long-term durability and cost efficiency.
How to Choose the Right Greenhouse Type for Your Growing Plan?
Choosing the right greenhouse affects yield, cost, and efficiency. Options range from plastic tunnels to multi-span, glass, and smart greenhouses, each suited for different climates, crops, and business goals.
The cost of building a greenhouse depends on the materials and design:
- Glass Greenhouses: These are the most expensive because they use high-quality glass and need a strong framework. They are ideal for high-end farming and long-term investment.
- Plastic Film Greenhouses: These are the most affordable. The plastic film (like polyethylene) is cheap, and installation is easy. It’s a good choice for small to medium-sized farms.
- Polycarbonate Greenhouses: These are moderately priced. Polycarbonate panels are good for insulation and can last longer. They are ideal for temperate or cold climates.
- Fiberglass Greenhouses: These are less common but offer strong durability and can withstand bad weather. Their cost is similar to glass greenhouses.
In general, plastic film greenhouses are the cheapest. Glass and polycarbonate greenhouses are better for long-term investments.
Glass Greenhouses:
- Advantages: High light transmission, durable, can withstand strong winds and heavy snow, ideal for high-value crops.
- Disadvantages: Expensive, installation takes longer, higher maintenance costs.
Plastic Film Greenhouses:
- Advantages: Low cost, easy installation, good insulation, ideal for small-scale or short-term use.
- Disadvantages: Shorter lifespan, needs regular replacement, lower UV protection and light transmission compared to glass.
Polycarbonate Greenhouses:
- Advantages: Good insulation, UV protection, long-lasting, suitable for many climates.
- Disadvantages: More expensive than plastic film, but cheaper than glass.
Fiberglass Greenhouses:
- Advantages: Strong and durable, can handle harsh weather.
- Disadvantages: Lower light transmission compared to glass, expensive, requires some maintenance.
When choosing the best greenhouse, consider:
- Budget: If you have a small budget, plastic film greenhouses are the most cost-effective. For a higher budget, glass or polycarbonate greenhouses are better options.
- Climate: In cold climates, polycarbonate or glass greenhouses are best because they provide good insulation. In warmer or tropical climates, plastic film greenhouses are often enough.
- Crop needs: High-value crops (like tropical plants or flowers) might need a glass or polycarbonate greenhouse because they offer better light and temperature control.
- Lifespan: For long-term use, consider glass or polycarbonate. If you need a temporary or small-scale solution, plastic film greenhouses are good.
Greenhouses come in several structure types:
- Arch Roof (Dome-shaped): The most common design. It’s easy to build, handles wind well, and helps snow slide off. It’s a good choice for most climates.
- Gable Roof (Pointed Roof): This type is better for areas with heavy snow or wind. It’s stronger than an arch roof but doesn’t let as much light in.
- Flat Roof: Less common, used for larger, commercial greenhouses. It’s suitable for some temperate climates but doesn’t handle snow or wind as well.
The arch and gable roof designs are most common for typical agricultural greenhouses. Flat roofs are used for larger-scale operations.
Plastic Film Greenhouses: They are usually double-layered or multi-layered, which provides good insulation. In cold climates, they help maintain a warm inside temperature.
Glass Greenhouses: While glass allows a lot of light, it doesn’t provide as much insulation as plastic film. Even double-glazed glass doesn’t keep the heat as well as plastic film.
Overall, if you need better insulation for colder climates, plastic film greenhouses might be the better choice. Glass greenhouses are better in warmer areas where light is more important.
Temperate Climates: For temperate regions, polycarbonate or glass greenhouses are the best. They provide good light and insulation and can handle seasonal temperature changes.
Cold Climates: In cold regions, choose a double-layered plastic film greenhouse or a polycarbonate greenhouse. Both provide excellent insulation and can keep the heat in during the winter.
In colder climates, ensure that the greenhouse has good insulation and a strong framework to survive strong winds and snow.
