10 Different Types of Greenhouses | Structures and Designs

Currently, there are over 1.2 million acres of land globally, occupied by different types of greenhouses. Today we explore these structures, identifying each type, including features that make them different.

A greenhouse is a structure that comes in handy when you want to grow plants in a controlled environment. This environment enables faster and healthy growth of plants no matter the season.

As you contemplate getting one, it’s worth noting that different types of greenhouses are ideal for different purposes, plants, and situations.

For this reason, the type of greenhouse you choose will primarily depend on your specific needs. And, some will work better in some situations than others.

But how are these greenhouses classified? What makes each category unique, and how do you choose the right one for you? We will see all that in a bit.

Types of Greenhouses Available Today

One primary way to classify a greenhouse is by looking at its structural shape or style. Each structure has its pros and cons that are worth considering before you make a purchase.

You can also categorize different types of greenhouses based on the frame material and outer covering. Here are the different categories of greenhouses available in the market.

Greenhouse Categorization Based on Structural Shape/Style

There are different types of greenhouses, and one way to categorize them is through their structural shape. Under this category, you get:

1. Lean-To Greenhouse

When you place a greenhouse against a side of a building, it falls under this classification. You can use the wall as one side of the greenhouse or place it in between two buildings. This leaves you with three or two sides to cover with greenhouse sheeting material, plus the roof for a full enclosure.

Most Lean-to types of greenhouses don’t exceed 12ft and can only carry 1 or 2 rows of plants at a time. However, you can extend it against an even longer wall if need be while ensuring it gets ample sunlight.

Pros

• Near to amenities like electricity and water from the main building.
• Smaller structure incurring less cost on materials.
• Requires a small space to set up.
• Fewer support requirements for the roof.

Cons

• Provides a limited space for plants.
• Doesn’t have enough light exposure for proper plant growth.
• Hard to control the temperature because of the wall sides.
• Height limitation due to the supporting wall.

2. Ridge and Furrow Greenhouse

Another perfect example of structural types of greenhouses is the ridge and furrow that resembles an A-frame structure. The design involves connecting the A-frame structures in a neat row. Each row connects at the eave, which is where all the excess snow and rain drains off.

This particular design is popular in a large farm setting where you have numerous greenhouses and don’t want any damage from rain or snow. The connection of several greenhouses acts to add more growing area, as well as increase the area for more sunlight penetration.

Also, this helps save on cost and energy to care for plants from one greenhouse to the next.

Pros

• Leaves enough room inside the structure for plants.
• Saves on automation and energy.
• Ensures structure longevity by draining rain and snow from the roof.
• An appealing look.

Cons

• Expensive to set up.
• Requires a big piece of land.

Examples of Ridge and Furrow Greenhouse

• Mini Walk-In Green House for Indoor/Outdoor

You notice the distinct A-frame structure of this greenhouse that you can set up as a ridge and farrow. All you need is to place the sides of the greenhouse to each other and open the ends to create one large room.

The frame structure uses top quality aluminum that’s not only durable but resistant to corrosion.

Addionattly, the A-frame roof structure ensures there’s ample heat distribution to help all plants to grow.

Also, the greenhouse comes with 8 plant shelves, and you can set it up in under 5 hours following the guide provided.

3. Even Span Greenhouse

These types of greenhouses are easily identifiable by their two distinct sloping roofs. You can comfortably use this design to set up a small greenhouse in your backyard, depending on your measurements.

As you set it up, you can consider attaching one end to the house or letting it stand on its own in the garden. You can also make it as big as possible to fit more rows and shelves that carry plenty of plants. All areas have a transparent glass or other material, helping plants get ample sunlight.

However, heating such a wide area can cost more. You might need to set up a heating system to keep temperatures from plummeting during cold days and nights.

Pros

• Flexible design that won’t limit you in terms of size.
• Spacious for carrying many plants.
• An ideal shape that maintains uniformity in terms of temperature.
• A-frame roof that ensures rain/snow doesn’t accumulate.

Cons

• Expensive to set up.
• Requires own heating system.

4. Gothic Arch Greenhouses

Picture any gothic structure you’ve ever seen, and you’ll get a clear image of a Gothic arch greenhouse. It has that distinctly pointed roof that helps eliminate the need to include trusses on the structure. Such a structure is ideal for both hobby and commercial use since it can be as small or as big as you want.

All you need is to note your space and expenses to decide on the size you want. Also, consider Gothic arch greenhouse’s pros and cons before making a choice.

Pros

• Versatile in that it can be a big or small structure.
• Appealing to look at.
• It makes it easy for snow and rain to drain off.
• It doesn’t require trusses.

Cons

• It takes up more materials when compared to other types of greenhouses.
• It doesn’t facilitate ample air circulation to the corners.

5. Uneven Span Greenhouse

You’ll notice a distinctive feature when it comes to the uneven span greenhouse. One roof of this structure is longer than the other, hence the name. The primary reason for this structure’s design is to allow more sunlight intake when the structure is in a hilly area.

Normally, the longer side of the roof faces the south and must be transparent. Given that most greenhouses are now in flat areas, this type of greenhouse isn’t as common.

Pros

• It helps sunlight reach the plants.
• Keeps wind at bay.
• Sturdy and long-lasting structure.

Cons

• Not ideal for flat areas.

Greenhouse Categorization Based on Frame Material

Every greenhouse requires a sturdy frame structure to give you optimal service. Without the right materials, the frame gets weak with time and can easily fall over. So in this categorization, you have a chance to learn the best materials to use on different types of greenhouses.

6. Pipe Metal Frame Greenhouses

Many pipe framed greenhouse structures use heavy-duty metals like steel and aluminum. These metals are long-lasting, which means you can use the greenhouse for a long time.

Once you opt for the metal pipe frame structure, ensure you know what metal is used since some are prone to corrosion. Also, it’s wise to use durable metal if the greenhouse is for commercial purposes as this reduces the cost of replacing worn-out pipes.

Pros

• Uses durable metal material.
• Provides a sturdy structure that can withstand the elements.
• Even in high temperatures, metal frame structures are resistant to heat.

Cons

• Heavy-duty metal is expensive.

What Type of Greenhouse is Ideal in What Location?

How can you choose the best site for a greenhouse? Is the greenhouse you have in mind the best for that location? Answering these vital questions helps you make the best selection in terms of location.

By following the tips listed below, you can determine the best types of greenhouses for various locations.

1. Sunlight Intensity

Some greenhouses suit areas with less sunlight, while others require intense solar radiation to facilitate plant growth. The best types of greenhouses in this situation depend on the location you choose for each. For example, you can opt for an uneven span greenhouse if you’re in a hilly location.

2. Land Size

How much land can you spare for a greenhouse? If you have a small piece of land, you can try mini greenhouses or lean-to design structures. Larger areas are good for bigger structures like Gothic Arch or Ridge and Furrow.

3. Weather Conditions

While you can set up a greenhouse anywhere, it’s best to keep in mind the weather conditions. Areas prone to months of snow are suitable for wood greenhouses that help retain warmth for the plants. On the other hand, those extremely windy areas need heavy-duty metal frames to keep greenhouses firmly arched to the ground.

4. Ground Stability

Not all surfaces are stable. Those with less stability require more heavy-duty frame structures like metal and thick wood. In areas with more stability, you can build plastic greenhouses without any worry. Also, you must choose a location where water drains off easily.
