Currently, there are over 1.2 million acres of land globally occupied by different types of greenhouses. Today we explore these greenhouse structures, identifying each class, including features that make them different.
If you’re interested in gardening or growing your food, you may have considered building a greenhouse. Greenhouses provide an ideal environment for plants, protecting them from Extreme weather conditions and pests.
Many different types of greenhouses are available on the market, so it’s essential to do your research before making a purchase. In this article, we’ll discuss the different types of greenhouses, their benefits, and critical features to look for when shopping.
Types of Greenhouses to Buy Today
One primary way to classify a greenhouse is by looking at its structural shape or style. Each structure has pros and cons that are worth considering before making a purchase.
You can also categorize different types of greenhouses based on the frame material and outer covering material. Here are the various 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 or attached to one side of an existing structure, it falls under this classification. You can use the greenhouse walls as one side of the greenhouse or place them between two buildings. Lean-to greenhouses leave 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 or window-mounted 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 while ensuring it gets ample sunlight.
- Near to amenities like electricity and water from the main building.
- Smaller structures incur less cost on materials.
- Requires a small space to set up.
- Fewer support requirements for the roof.
- It provides limited space for plants.
- It 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 a structural greenhouse type is the ridge and furrow that resembles an A-frame structure. The design involves connecting the A-frame greenhouse structures in a neat row. Each row relates to the eave, where all the excess snow and rain drains off.
Steel-blue roof shingles and white or dark wood paneling give this A-frame structure a classic country look. It’s inexpensive to make and can be constructed with only basic materials. This greenhouse may be built with very little use of wood or plastic film coverings in your home.
It also requires little construction knowledge. Because of the broad base and short height, the peaks may be more challenging to maneuver, and the heights are low. Airflows aren’t always ideal around the lower edges or tight angles.
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.
- It leaves enough room inside the structure to grow plants.
- Saves on automation and energy.
- Ensures structure longevity by draining rain and snow from the roof.
- An appealing look.
- Expensive to set up.
- Requires a big piece of land.
