But to harvest vegetables and fruits rich with nutrients or blooming flowers in and out of season, your choice of greenhouse matters a great deal. If you ask any gardener out there, they will agree that getting the right greenhouse that rhymes with all your needs is also not an easy task.
You must embark on serious research, for you to be able to identify the best greenhouses among the large possibilities in the market. During your research, however, there some vital differentiators that you must consider to help you make the right choice.
Here is where this guide comes in. We have compiled a list of 14 greenhouses, based on in-depth research plus the various online greenhouse reviews from satisfied users.
But before we have a look at the greenhouses, here are some crucial facts that you must know before you make that purchase.
Things to Know when Buying a Greenhouse
Although many people presume that every greenhouse is suitable for any plant, there is another side of the coin.
We are talking about long service, size, materials, and design. But, these small factors have an impact on how your plant will look like when the harvesting season comes. Some more vital traits of a greenhouse that you must put into consideration before you buy include:
In many cases where plant failure is recorded in a greenhouse, the lack of proper ventilation is always the first suspect.
Ideal greenhouses should retain warm air during winter and release it during summer. If this cycle is interfered with, your plant growth gets distorted
Proper ventilation does not only depend on your chosen greenhouse but also the location. The location should have excellent airflow to ensure that air can enter and exit the structure smoothly. Alternatively, you can purchase solar-powered louvers to take away ventilation stress.
Metal or Timber Greenhouse
Wooden timber greenhouses are beautiful but very expensive. You will also invest more time in its upkeep. The good thing is that it’s perfect in marinating room temperature.
Metal greenhouses, more so those made out of aluminum, are perfect if you don’t want to spend a fortune in your gardening. They also have low maintenance requirements.
The Shape of the Greenhouse
The greenhouse’s shape is something that many gardeners don’t keep in mind. What they miss out is that a wrong shape/design will affect air and light circulation inside the structure.
There are four types of shapes you’ll come across. We shall talk about them in detail when reviewing the individual greenhouses.
- Domes (Newer versions)
Size of the Greenhouse
Research has it that most gardeners wish they had chosen a bigger greenhouse when starting. You shouldn’t make the same mistake.
Choose a larger greenhouse, even if you are thinking of having a few plants in the garden. The only thing that should change your decision is these two scenarios.
- When the space you want to seclude for gardening is limited
- You are looking for a greenhouse for a small “flower farm.”
It’s essential to choose a greenhouse with a width of at least 6 – 8 feet. The eaves should be at least 5 feet to allow more light to enter the structure.
A large greenhouse gives your plant room for perfect growth and limits competition for space. Besides, you may want to change your small garden into a small farm in the future. You never know.
The Extent of Plant Protection
Your plants, of course, are protected from harm when inside the greenhouse. Pests and animals may not easily attack, and strong winds are also prevented from ravaging your garden.
But how far can the greenhouse go in protecting your plants?
You have to prepare yourself to battle other intruders like bugs, slugs, worms, and different types of pests. Unfortunately, only a few of the best greenhouses can offer extra protection. It’s something that you have to check if your location is infested.
Benefits of a Greenhouse to Plants
Extended Growing Season
Typically, extending your harvesting period is how greenhouses work. For a long time, farmers have tried the best way to do this but were unable. The invention of greenhouses was able to downplay the climate.
Today, when you prepare your seedlings early in the season, it is possible to get a bounty harvest earlier than other farmers.
You Can Grow a Variety of Crops in a Single Structure
A greenhouse gives you room to try out different plants at the same time. It’s a significant advantage because you can experiment on exotic plants which are not easy to find.
Still, ensure that what you want to inter-crop are mutually compatible for maximum harvest.
Greenhouses are Environmental-Friendly
Environmentalists agree that these structures fight the greenhouse effect in a great deal. That’s why they advocate for their use in modern farming.
Adding more plants in the structure helps provide fresher plants. The oxygen plants excrete is what cleans the atmosphere and fights global warming.
Traditional gardening does not reduce the use of energy. Why do you think modern farmers have taken the shift? Greenhouses can conserve energy sources like heat and water as they are easily controlled.
Portability and Customization
Most of the greenhouse, which we will discuss are portable. You can place them in areas with maximum sunlight and in which they are easily accessible. The greenhouses are easy to assemble hence reliable when always on the move.
Also, structures like ShelterTech High Tunnel greenhouses enable you to make personalized structures to accommodate planting needs. You can configure them to include the frame, end panels, and cover. Besides, you can get a complete kit with size options of up to 100 feet.
Enough about that! We can now have a look at the 14 best greenhouses to buy in 2020
