Types of Outdoor Greenhouse

Outdoor greenhouses are not only of a singular category. Instead, they come in different types based on size, shape, and purposes. Right now, we’d like to go through some of those different sorts of greenhouses.

Lean-to Greenhouse

Just as the name suggests, lean-to greenhouse refers to those particular greenhouses that work while they’re situated against the boundary of a building structure. It mainly takes advantage of the existing structure and minimizes cost for your complacency. It also offers better protection against winds because of its attachment to a stronger structure.

Even Span Greenhouse

Even-span greenhouse refers to the regular greenhouses we find around. These sort of greenhouses offer better light and are more productive than their lean counterparts. Plants grow quickly as they get light from all four sides of the structure.

Uneven Span Greenhouse

It’s a subcategory of the even span we just mentioned. These are chiefly employed in hilly terrain. It gets its name from the uneven roof structure it has to incorporate because of the mountainous region.

Ridge and Furrow Greenhouse

Ridge and furrow greenhouse is a type of greenhouse where multiple A-frame greenhouses are connected. These are mostly used in Northern Europe and Canada.

Quonset Greenhouse

This is yet another type of greenhouse which is used around the globe. Usually, polyethylene is used to cover the greenhouse. They’re generally shaped round. It’s better suited for automation and relaxed movement.

Portable Outdoor Greenhouse

Finally, the portable outdoor greenhouse refers to those types which come with easily attachable/detachable parts. As a result, they can be folded up easily and move to a different location without hassle. Usually, these types are lightweight and come with PVC plastic covering, making them lighter while offering better humidity control and airflow. Our guide particularly focuses on this type of greenhouse.

Difference Between Indoor and Outdoor Greenhouse

Because of numerous benefits, greenhouses are not only bound outdoors only. Instead, there are countless numbers of indoor greenhouse models available in the market right now. Here, we’d try to locate the difference between these two types of greenhouse.


The first thing these two types of greenhouses differ in is their size. Generally, the outdoor greenhouses are large in shape; they can house a large number of plants, as opposed to their smaller indoor counterparts.

On the other hand, indoor greenhouses are designed small because they’d have to be fitted inside the house.


Outdoor greenhouses need to be tough and sturdy. Both the frame and the PVC cover have to be strong enough to withstand winds, rain, and snow. As a result, they’re constructed using tougher materials. While the indoor counterparts don’t face any of those challenges above, that’s why they don’t need to be that much durable either.


They also vary in terms of purpose. These are chiefly employed for serious farming needs. They’re often used by skilled and professional individuals. At the same time, indoor greenhouses can be used by people, in general, to germinate seeds or grow small plants.


In terms of portability, indoor greenhouses are far ahead of their larger counterparts. They offer an unbelievable portability advantage which is highly effective while shifting them from one house to the next.

But that is not exactly the case with outdoor greenhouse. Their installation is more complicated and requires plenty of time assembling compared to the indoor greenhouse.

These are some of the key issues where the two types of greenhouse differ mostly.

Reason to Buy an Outdoor Greenhouse

Outdoor greenhouses are heavily increasing to become a general trend among the people. But why is it? We’ll discuss here some of the key factors why greenhouses are becoming much more important each day!

The Green Revolution!

Most of the greenhouses we discussed come with PVC coverings. PVC coverings offer this balanced state trapping the heat during colds and maintaining better airflow.
