There are different kinds of greenhouses. Some stick to buildings and save money. Others stand by themselves and let you choose where to put them. There are also low ones called cold frames that keep plants safe from the cold. Hoop houses are like tunnels and help plants grow for longer. Some greenhouses have curved roofs to let in more sunlight. A-frame ones are smaller and good for pretty plants.
Glass ones look nice but need more care and cost more. Some have many parts and help grow lots of plants, while others focus on using sunlight well. The type you pick depends on space, what you want to grow, weather, and money. Each kind has its good parts and things to watch out for.
How do different greenhouse structures vary?
These classifications provide insights into choosing the most suitable greenhouse structure and material based on specific needs, climates, and intended use cases.
Based on Structure
Traditional/Conventional Greenhouses
These are the most common and classic greenhouse structures with a rectangular or square shape and a peaked roof. Typically made of glass or plastic panels, they offer ample headroom and space for cultivating various plants. Efficient use of space, easy to construct, and provide uniform growing conditions.
Lean-to Greenhouses
Attached to a building or structure on one side, often utilizing an existing wall for support. Space-saving and cost-effective; benefit from the thermal mass of the building to regulate temperature.
Less material is needed for construction, easy access to utilities, and convenient access from the adjoining structure.
Dome-shaped Greenhouses
Geodesic or spherical structures that provide excellent strength and stability. Utilize less building material due to their inherent strength, provide good air circulation, and are visually appealing.

Plastic (Polyethylene) Greenhouses
Constructed using polyethylene sheets or films stretched over a frame. Cost-effective, lightweight, and comes in various grades for UV protection and insulation. Easy installation, flexibility in design, and affordability.
Polycarbonate Greenhouses
Use polycarbonate panels known for their durability and strength. In addition, excellent insulation properties, is lightweight, and is resistant to impacts and harsh weather conditions.
Efficient heat retention, UV protection, and longer lifespan compared to some plastic materials.
Acrylic Greenhouses
Constructed using acrylic panels known for their transparency and durability. Excellent light transmission, stronger than glass, and lightweight.
Resistant to yellowing, offers good insulation, and allows better control of temperatures.
What are the functions of various greenhouse types?
These distinct types of greenhouses based on function help in choosing the appropriate structure and features depending on the scale of cultivation, desired plants, and specific goals, whether for personal use or commercial production.
Cold Frame Greenhouses
Cold frames are low, unheated structures with transparent covers (typically glass or polycarbonate) that are placed directly on the ground.
Primarily used to extend the growing season by creating a microclimate that protects plants from frost and cold temperatures.
Suitable Plants and Usage
Cold-hardy vegetables, herbs, and flowers that can withstand cooler temperatures. Starting seeds earlier in the spring, hardening off seedlings, overwintering plants, and providing a protected environment for early growth.
Season Extender Greenhouses
Similar to cold frames but larger in size, these greenhouses aim to extend the growing season by moderating temperature and protecting plants from adverse weather conditions.
Typically use passive solar techniques, incorporating thermal mass, insulation, and ventilation systems to regulate temperature.
Ideal Plants and Applications
More tender vegetables, flowers, and fruits that require additional protection from cold or unpredictable weather.
Starting plants early, growing heat-loving crops in cooler climates, and protecting plants from late frosts.
Hobby Greenhouses
Hobby greenhouses come in various sizes and designs, ranging from small backyard structures to medium-sized enclosures.
Cater to gardening enthusiasts or hobbyists for personal enjoyment, experimentation, and growing specific plants or varieties.
Different Designs and Functionalities
Designs can be freestanding or lean-to structures, made of various materials like glass, polycarbonate, or plastic.
Functionalities are often equipped with basic ventilation, heating, and shelving systems, customizable to suit individual gardening preferences.Commercial/Professional
Greenhouses
Large-scale Structures for Mass Production
These are expansive greenhouses designed for commercial agriculture, ensuring high yield and efficiency in crop production.
Aimed at mass-producing vegetables, flowers, and other crops for sale in markets or distribution to retailers.
Technological Advancements and Features
