Apart from the ability to grow multiple kinds of crops and plants throughout the year, you also get to have maximum yield, protection against extremities of weather.
A greenhouse is ideal for gardeners who’re involved in taking cuttings, sowing seeds, growing tender crops and plants, and overwintering them. Greenhouses help you control the climate inside them and ultimately extend the growing season. You can grow tropical and subtropical plants in relatively cold weather with the help of these greenhouses.
A greenhouse, after all, is a big investment and not that easy to install or remove once done. Thus, you need to be careful when picking one. For that, we’ve reviewed some of the best greenhouses in 2022 along with some tips and tricks to maintain them.
A Buyer's Guide To Help You Find a High-Quality Greenhouse
There are some factors one must always consider before buying a greenhouse. This guide comprehensively explains them:
What Is a Greenhouse?
Greenhouses simply are built to give plants the appropriate environment they need to grow and multiply. They are made to protect out-of-season and tender plants from the extremities of the weather outside.
Greenhouses work on the basic principle of trapping and retaining heat energy. This heat induces and promotes plant growth in off-season plants. You can use greenhouses to have a supply of your favorite flowers and plants throughout the year.
Greenhouse coverings are made from materials like polycarbonate, polyethylene, or glass that let the heat from the sun and other sources pass through into the enclosed space. This heat is trapped inside the space and is absorbed by plants.
Carbon dioxide is a free and heavy natural gas, that stays at a lower level in the greenhouse. Carbon dioxide enrichment in greenhouses allows crops to meet there photosynthesis potential. However, it is essential to monitor the carbon emissions through sensors, and adjust to required level. Commercial greenhouses use paraffin lamps inside a greenhouse to increase the rate of photosynthesis, as burning paraffin produces carbon dioxide as well as heat.

Things To Consider Before Buying a Greenhouse
Setting up a greenhouse is not easy. You must consider numerous things to give your plants the much needed care. While professionals at garden centers can offer you the best tips about choosing plants, we have assembled tips that can help you in choosing the best greenhouse for your backyard or deck.
Material of the frame
You can either get a wooden frame or a metal one for your greenhouse. Aluminum is a cheaper option between the two and is also very long-lasting. It’s low maintenance and you can also powder coat it in a wide range of colors.
Wood, particularly timber, is a common choice amongst people who want to make their greenhouse and the space around it attractive. They do require more upkeep and are relatively expensive. They are however better at maintaining the temperature inside for longer times. You can glaze them to the ground or make a lean-on greenhouse out of wooden ones.
Greenhouses come in a large range of sizes. They come in 2ft increments of a range of widths and lengths. The ideal size would be a 6ft wide and 8ft tall greenhouse that will enable you to put shelves on each side.
The eaves of your greenhouse should at least be 5ft tall so it can allow plenty of light in for the plants. The size also depends on the kind and quantity of plants you’re planning to maintain.
The shape of your greenhouse is important because it decides what movability options you’re going to have. There are three main shapes, lean-on, traditional, and octagonal. You can also go to domes.
Dome or octagonal shapes are perfect for those who don’t have large, square of ideal spaces for their greenhouses. Lean-on leans onto already exiting walls and take heart from the bricks of the house as well. This helps them maintain a constant temperature throughout the year.
Ventilation is another important factor that your greenhouse should have. Especially for the summer season, a mesh door is perfect to let fresh air in while preventing invasion from bugs or small animals around. Most greenhouses have hinged roof vents, side vents, windows, and doors for ventilation purposes. Sufficient vent openings around the perimeter of the greenhouse is essential as cross ventilation is ideal for natural gas to escape.
Where Should a Greenhouse Be Placed?
There are limited areas where you can put a greenhouse in your house. Here are some simple tips for choosing where to place a greenhouse:
You should look for a spot that is sheltered but avoid placing it under a tree because there is a risk of potential damage there.
Place your greenhouse at a spot that receives an abundance of sunlight. Sunlight is necessary for plants to grow and it helps maintain a warm, suitable temperature inside.
Don’t place the greenhouse at a place where it will be exposed to winds. No matter how big or heavy, storms and heavy winds tend to damage it.
There should be plenty of space around all sides of a greenhouse. There must be space for efficient cleaning and room for greenhouse-raised crops and plants outside.
Get one that can be placed as near to the house as possible so that it can remain warm without electricity or any other source.
Types of Greenhouses
There are three basic kinds of greenhouses. Let’s take a look at all of these:
Pop-up greenhouses are also known as ultra-mobile greenhouses. They look somewhat like freestanding ones but are small in size overall. They are highly portable and usually very easy to assemble and disassemble.
You can easily pack it up and move it to a space that you like. When you can easily transport a greenhouse, it becomes easier to get the right amount of sunlight at the right position in different weather conditions.
Lean-to greenhouses are attached to the outer walls of your home or building. These greenhouses are rather smaller and have less space inside for people to walk inside them. They are great to keep little plants and crops and grow them to a certain size.
This is the perfect choice for a backyard greenhouse maintained by occasional or casual gardeners. They are usually cheap but if you plan to get wooden frames attached to your house with it, it can turn into a costly project.
Lean-to greenhouses are energy-efficient and give the house a nice look from the outside.
This is the most commonly used gardening greenhouse. These greenhouses are like small separate houses with their own construction and independent structures. They commonly have A-Frame-shaped roofs with a round-arch shape to keep water and snow from accumulating on the top.
Free-standing backyard greenhouses are expensive as they require much more material and serious construction than the other two kinds. They are spacious and allow you to keep a lot of plants inside.
It can get hectic and confusing when you have to invest in something that’ll determine the future of your little green buddies. Make sure you land the best greenhouse in 2021 by taking help from this guide.
