Types of Greenhouse
While choosing the right greenhouse for yourself, you need to understand your needs and compare them with the features of home greenhouse kits to find the perfect one for yourself.
Lean-to Type Greenhouse
The lean-to type greenhouses are designed to place along with buildings. If you don’t have a large space in your backyard, then you can choose a lean-to type greenhouse to use. With its limited space areas, you can set up small and a few plants of your choice.
Even Span Type Greenhouse
As the most commonly used greenhouse in Asia, the even span type greenhouses are known as a standard type, which is constructed in such a way that the roof pitch is the equally divided length and angle wise on both sides.
Generally, it is less expensive than other greenhouse designs. This design uses for a small-sized greenhouse. The flexibility in design and more room for plants makes this design superior to others.
Uneven Span Type Greenhouse
If you live up in the mountain areas, then you should look into the uneven span type greenhouses. The construction design of these greenhouses totally blends in and adapts with craggy terrains.
Its roof pitch is unequal from one side to another, making the structure perfect for side slopes of the mountain. As the design was not adaptable enough to various situations, they are very rare now.
Ridge & Furrow Type Greenhouse
This so-called “Gutter connected” design consists of several greenhouses being connected along the length of it, removing the wall in between, providing more free space and growing space.
Despite snow loads, these greenhouses are effectively used in northern countries of Europe and are also suited for Asia. As less costly conservation of more ground area, they are very energy-efficient.
Saw Tooth Type Greenhouse
While the connected houses use roof ventilation, it creates the shape of teeth and saw, rather getting its design named as Saw Tooth-type greenhouse.
You can call this type an upgrade of Ridge & Furrow type greenhouse. It is also interconnected, but with an extra provision on the roof, ventilation is used for a natural ventilation flow path.
Getting the reference from Quonset huts during WWII, this design named itself as Quonset Greenhouse. The shape of the rooftop is exactly similar to huts, and semi-circular structures look like barrels cut in half.
They are less costlier than the gutter connected greenhouses and are efficient when used in small areas. The houses are connected in many ways, and the overlapping portions of adjacent houses get enough airflow.
Things to consider before buying the right Small greenhouse for you ( Buying Guide)
Now that we have done reviewing our top 7 backyard greenhouse kits, it’s time for you to go through a small buying guide so you can choose the right greenhouse for yourself.
Tips for Sizing Your Greenhouse
Before sizing your greenhouse, think about the size of your backyard. You will find a lot of greenhouse kits for sale, but before buying one, determine the amount of space you have in your backyard.
If you have a small backyard, then you need to look for a 4×4 greenhouse, but if you have a large backyard, then you can think about getting a large one.
So before the growing season starts, go get a suitable greenhouse for yourself that will be a perfect fit for your backyard.
Greenhouse Covering Materials
Once you have got a suitable greenhouse for yourself now, you will need the supporting materials for your greenhouse. The first most important accessory that you will need is covering materials.
You will need good materials to cover your paneling. If you are planning to seed, then you will need a clear polycarbonate panel. If you are planning to grow plants during their maturity stage, then you will need an opaque panel. If you are planning to grow seed to harvest in your greenhouse, then get a twin wall polycarbonate system.
Determining Greenhouse Design by Climate
Once you have decided what covers you are going to use, now it is time to think about the climate and how it will affect your greenhouse. The environment will always play a vital role in the choice of your greenhouse kit.
If your surrounding consists of cold weather for most of the time, then you’ll need a greenhouse that can keep your plants warm. If you are surrounded by heavy rains and terrifying winds, then you will need a strong greenhouse that can stick to the ground instead of blowing away. If you live in an environment surrounded by warm weather, then you will need a greenhouse with a good ventilation system.
Make sure you determine your surrounding environment as you buy your greenhouse kit.
A greenhouse is like a raw material that needs to be fulfilled by additional accessories. Among all the accessories such as frames, panels, and covers, you will need something to control the surrounding environment of your plants. So here are some pieces of equipment that you must purchase.
Install a heater in your greenhouse to keep your plants warm during the colder days. The cold temperature of the winter will freeze your plants to death. So to avoid emergency situations like this, install a heating system in your greenhouse.
When you build a garden full of plants, pests will be crawling towards it. Once they get onto your plants, you will see your plants getting ripped day after day. So to keep these tiny creatures away from your plants, you need to start taking action as soon as possible.
Gather a good amount of sprays or buy a burner to keep the pests and bugs away.
Lighting is important during the winter season. If you live on the northern side, then you know how cold it gets during the winter. Your plants will crave for artificial lights during that time so install a proper lighting system.
Air Management System
In the warmer days, due to excessive heat, your plants might burn to death. To avoid situations like this, install a greenhouse fan that will continuously blow the warmth away from your plants. As the air keeps blowing, the temperature within your greenhouse will begin to get out, and your plants will be fresh and enlightened.
Frequently Asked Questions
Even after all these reviews and step-by-step guides, you’ll have a ton of questions. Maybe I can’t answer all of your questions, but here are some quick faq’s to clear your mind.
Are mini Greenhouses any good?
Mini greenhouses have their own superpowers. They were never made to do all types of gardening. They were made for gardeners with a small backyard and loves to garden during their free time.

What can I grow in a small greenhouse for beginners?
As a beginner, you can grow starter plants at your greenhouse. Starter plants as if easy to grow plants, it can be flowers or vegetables.
You can start planting vegetables such as eggplants, spinach, carrots since these are easy to grow. If you are into fruits, then you can seed strawberries, tomatoes, or cucumbers. If you are into flowers, then grab some seeds of marigold, sunflowers, daisies, etc.
When you are simply starting, you wouldn’t want to go into the hard stuff because then it will require advanced tools and cultivation that might stress you out. So you can simply start off with the easy ones.
Is it cheaper to build or buy a greenhouse?
Every process has its own advantages and disadvantages. If you go and buy a greenhouse, then you will have an instruction and multiple features attached to it that are made by professionals. So this is a perk of buying a greenhouse.
Now, if you plan to build a greenhouse, then you’ll need to determine the materials you want to use, the size of the greenhouse, and how you want to set it up. This is a long process, and the number of items will determine the total cost of your greenhouse.
The plus point of building your own greenhouse is that you can customize it the way you want, but it’s too time-consuming.
So here’s the catch, if you scroll through a market place you can buy a cheap one, but in terms of building a greenhouse by yourself, then it depends on what materials you use.
Where to set up your Mini Greenhouse?
You have bought a mini greenhouse because you have a small backyard, right? But a small greenhouse isn’t only for your backyard because some greenhouse can be placed indoors as well.
You can set up your greenhouse on your balcony, lawn, yard deck, or patio. Wherever you place your mini greenhouse, please avoid placing your greenhouse in an open area where it will be vulnerable and can be easily blown away by the wind.
I would suggest you to place your greenhouses near a wall or a fence and position it in a way, so it doesn’t fall over.
It is not easy to say, but these small backyard greenhouse kits do not come with fancy accessories, but it does help you in many ways as a gardener. You and I have discussed seven different greenhouse kits, and I hope you find a suitable one for yourself.
But before you buy a greenhouse, I would recommend you to read the buying guide properly, so you know how to determine which one you need because once you order a greenhouse, there is no turning back.
If you have previous experience in buying greenhouses, then you would know better than me, well maybe.
