Types of Outdoor Greenhouse Kits

Outdoor Greenhouse Kits

An outdoor greenhouse is 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, a lean-to greenhouse refers to that particular greenhouse that works 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 greenhouse we find around. These sorts 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, where multiple A-frame greenhouses are connected. These are mostly used in Northern Europe and Canada.

Quonset Greenhouse

This is yet another type that is used around the globe. Usually, polyethylene cover design is used for the greenhouse rooftop as cover. 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.

What Type of Greenhouse Should You Build?

Difference Between Indoor and Outdoor Greenhouse Kits

Because of numerous benefits, greenhouses are not only bound outdoors only. Instead, there are countless numbers of indoor greenhouse models available on 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 greenhouse 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, an indoor greenhouse 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 greenhouses. 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 Kits

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

Green Revolution

Agree or not, a new revolution has begun. A sharp shift in the mindset of common folks can now be observed easily. The continuous infiltration of the chemical and other health-damaging materials in the food industry has created a deep sense of disbelief among the people. Further, the rapid use of GMOs has divided the scientific community as well as the larger population, many claiming GMOs cause numerous long-term health issues.

Because of all these reasons, almost everyone is thinking about growing their food. And thus, the greenhouse is at the forefront of this newly formed movement. So, if you’re one of those who wish to remain safe and secure in the food department, a greenhouse should be a must-add-on.

Provides Longer Season for Growing

We often have the desire to have fruits or vegetables when they’re not available in the market and even if they are it’s beyond. While the greenhouse can easily extend the growing season of the plants. As a result, you can get tomatoes in winter and other crops even if they’re not in their season.

Prevent the Crops from Pests

Pests are one of the most irritating elements that disturb the natural harmony of plant growth. But with greenhouses, the plants remain protected from these problems. Also, check How to Keep Bugs Out of Greenhouse

As a result, a balance is formed inside, neither too hot nor too cold and offers optimum, controlled weather for ideal plant growth.

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.

Beautifies the Backyard

When the greenhouse shelters mind-blowing flower gardens, the beauty it generates is beyond words. It makes a wonderful add-on and takes the guests by surprise! Backyard Greenhouse is certainly one of the most highly attractive items you can think of.

Buying Guides

Best Outdoor Greenhouse

If you’re looking for a small greenhouse, there are some tricks you should remember. It can be difficult to dig out a quality solution from thousands of other items in the market. Let’s now look at some of them, so you can make a good bargain.

Better Ventilation

Without proper air, plants will never grow and provide the expected requirements. That’s why it’s critical to seek out a greenhouse that has an authentic ventilation technique from the roof vent. As a result, your plants would get the necessary air from the outdoors, which would reinforce the plant cell walls, which makes them stronger.

It’s also better for pollination and harvests. So, it’s a must on your part to make sure the item incorporates intelligent engineering techniques for fruitful and effective air ventilation.

Larger Capacity

You’d always have to make sure of the amount of room the greenhouse is coming with. For an outdoor greenhouse, you’d always want to grow as many plants as possible, and reaching the space limit is one of the most irritating factors that you may encounter during the process.

That’s why we highly recommend you to get a greenhouse which is spacious enough to house lots of trees.

Durable Build

Outdoor greenhouses have to be strong! No alternatives are there for a durably built greenhouse. Because an outdoor greenhouse would naturally be under the constant battering of wind, rain, snow, and countless other natural phenomena, if it’s not built strong enough, it’d become a burden on your shoulder, fixing it every two weeks. If you don’t want such an event to take place, finding the toughest outdoor greenhouse would be the best course of action out of all.

Also, look for the greenhouse that offers rope and anchor installation possibilities that would aid them during stormy weather.

Installation Difficulty

These are portable greenhouses and they’re meant to be used in a way that involves installing and folding in different times and situations. That’s why we’d always recommend Greenhouse which is easy to assemble.

Easier installation is the selling point most greenhouse manufacturers use and for the right reasons as well. It makes life easier and helps to take it wherever you want to.

Strong and Effective PVC Covering

Another important factor when choosing the top outdoor greenhouse is the issue of coverage. If the covering is built well, then it would provide better protection against the weather. Weather protection is one of the primary activities of a quality greenhouse.

And an effective PVC covering can ensure that. For that particular reason, we’re strongly suggesting you find a greenhouse option that offers a striking PVC covering for quality weather control and maintaining air quality inside. Aside from PVC, polycarbonate panels work well, and finding the best polycarbonate greenhouse can also do the job!

We’ve outlined some of the key mechanisms of a quality greenhouse. If you manage to find a greenhouse solution that incorporates all the above-mentioned criteria, it’s safe to go for it without hesitation!
