Types of Greenhouses

Types of Greenhouses! A Detailed Comparison for Every Gardener

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.

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.

Efficient use of space, withstands heavy loads like snow, and offers a unique aesthetic.

A-frame Greenhouses

Triangular-shaped structures resembling the letter “A” in their design. Simple construction allows for efficient rain and snow runoff and provides good air circulation. Good for areas with high precipitation, visually appealing, and can be easily expanded.

Gable or Even-span Greenhouses

Rectangular-shaped structures with a pitched roof, similar to traditional greenhouses but with a uniform roof slope. Offer uniform height and maximum space utilization from wall to wall.

Suitable for large-scale commercial operations, efficient use of space, and easier installation of heating and cooling systems.

Based on Material Used

Glass Greenhouses

Historically common, made of glass panels or sheets that allow maximum light transmission.

Provide excellent light quality for plants, durable, and maintain consistent temperatures. Longevity, aesthetics, and superior light transmission for optimal plant growth.

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 


Large-scale Structures for Mass Production

How do hydroponic and solar greenhouses work

These specialized greenhouses demonstrate innovative approaches to agriculture that emphasize resource efficiency, sustainability, and technological advancements.

Hydroponic Greenhouses

Hydroponic greenhouses are designed for soilless cultivation, where plants grow in nutrient-rich water solutions instead of soil.

Increased crop yields, water conservation (up to 90% less water usage compared to traditional soil farming), faster growth rates, and precise control over nutrient delivery.

Plant Cultivation Methods and Systems

Various hydroponic techniques include deep water culture, nutrient film technique, aeroponics, and drip systems.

Utilize pumps, reservoirs, growth media (like perlite or rockwool), and specialized nutrient solutions to provide essential elements directly to plant roots.

Solar Greenhouses

Solar greenhouses harness solar energy for heating, lighting, and power within the structure.

Passive solar techniques, such as orientation, insulation, and thermal mass, capture and store heat from the sun. Some solar greenhouses integrate photovoltaic (PV) panels to generate electricity for lighting, ventilation, and other energy needs.

Sustainable Features and Benefits

Reduce reliance on fossil fuels by utilizing renewable solar energy, leading to lower operational costs and reduced carbon footprint.

Lower energy costs, extended growing seasons, minimized environmental impact, and increased self-sufficiency.
