Our top pick is a portable greenhouse that uses space sparingly. Still, it’s large enough to care for tender seedlings that can’t compete for air, water, and warmth.
The structure has rock-solid stability to hold pots, plants, and seed trays. Thanks to the sturdy tubes, which weigh 18 lbs capacity. This is strong enough to withstand mild storms that move at 30mph. If you are still worried, it has additional tie-downs for more stability.
Nothing makes a gardener happy like seeing plants growing well. The secret here is air circulation. Air movement in plants facilitates gaseous exchange, mitigates mold growth, and increases the weight of leafy plants.
Ohuhu greenhouse has leveraged the power of air movement since it is designed with zippered roll-up doors. The Velcro side windows perform the same function. It’s, therefore, the perfect structure if you are planting nurseries or plants that need constant air circulation for optimum growth.

To some people, gardening is not something they think of doing for the long term. It’s their love for plants that forces them to purchase a greenhouse. It’s these people that Gardman greenhouses tend to reach. Maybe you want something simple and affordable to hold a few of your favorite flowers.
First of all, it’s incredibly lightweight, which means that setting it up is similarly straightforward. It’s only 27 by 8 inches, which gives room for four shelves after rolling up the zipper door.
If getting that extra space is something you will mule over for long, Gardman has prioritized using the smallest area as much as possible. Your balcony is enough to hold the whole structure.

This makes it possible to keep your plants and flowers fresh and beautiful. You can overwinter plants in other climatic areas because flowers bloom earlier during spring and summer.

Things to Know when Buying a Greenhouse
Although many people presume that every greenhouse is suitable for any plant, there is another side to the coin. We are talking about long service, size, materials, and design. But these small factors impact your plant’s appearance when the harvesting season comes.
Some more vital traits of a greenhouse that you must put into consideration before you buy include:
Hardcover or Softcover?
The choice between a hard-paneled or soft-covered greenhouse depends on your environment and frequency of use. Hard panel greenhouses, mostly made of high-quality polycarbonate sheeting, are suitable for temperature control and light provision.
These are wind-, snow-, and ice-resistant. On the other hand, lightweight and portable options of flexible polyethylene covers or PVC fabric work better for basic home gardening during colder months but may require more frequent replacement.
Shelving options vary among greenhouse kits. Some may not include shelves, while others offer built-in or modular shelves. Examine your needs and determine whether adjustable, modular shelving would be the best choice for starting new plants or accommodating various heights.
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 depends not only on your chosen greenhouse but also on the location. The location should have excellent airflow to ensure air can enter and exit the structure smoothly. Alternatively, you can purchase solar-powered louvers to take away ventilation stress.
Consider your local weather conditions when evaluating the sturdiness of a greenhouse. Heavy snow, strong winds, or extreme temperatures demand a more durable and stable structure. A precisely fitted frame with a cover and well-secured to the ground works best in harsh conditions.
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 for marinating at room temperature.
Metal greenhouses, more so those made of aluminum, are perfect if you don’t want to spend a fortune on 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 on 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)
Check out these different types of greenhouses that you need to know about. There are a ton of different structural considerations as well as design considerations.
Size of the Greenhouse
Research shows 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 considering your greenhouse or 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.”
Choosing a greenhouse with a width of at least 6 – 8 feet is essential. 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. You never know. Here are some guides that will help you:
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 must prepare to battle other intruders like bugs, slugs, worms, and 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. Farmers have tried the best way to do this for a long time but have been unable to. 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. This makes greenhouses an excellent transition to sustainability in terms of more efficient farming and gardening.
You can use aquaponics kits to extend your growing season.
You Can Grow a Variety of Crops in a Single Structure
A greenhouse gives you room to try out different plants simultaneously. 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 is mutually compatible for maximum harvest.
Greenhouses are Environmental-Friendly
Adding more plants to the structure helps provide fresher plants. The oxygen plants excrete is what cleans the atmosphere and fights climate change.
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 greenhouses which we will discuss are portable. You can place them in areas with maximum sunlight and in which they are easily accessible. The portable greenhouses themselves are easy to assemble and 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.
You have to understand that the above greenhouses are not best for everyone. Some will go for the Outsunny portable or Monticello greenhouse, while others will pick another brand. It all depends on the needs and tastes of everyone.
If you were careful, you must have noted that almost all the greenhouses are made with polycarbonate material and steel for the bars. So you ask yourself? What’s the main difference? The perfect answer to that question depends on you. The ball is still in your court.
- What’s your budget?
- What is your purpose for purchasing a greenhouse?
- Do you understand what you need?
You are good to go if you can answer these three questions satisfactorily. This is the secret to picking the best greenhouse to buy.
Which type of greenhouse is best?
The best type of greenhouse often depends on individual needs, but the freestanding greenhouse is widely appreciated for its flexibility. A freestanding greenhouse can be placed anywhere on a property, allowing for optimum sunlight exposure. It offers ample space for various plants and can be easily expanded.
What is the most reliable greenhouse?
The most reliable greenhouse is generally a professionally constructed, permanent structure made from durable materials like polycarbonate and aluminum. This type of greenhouse, often called a traditional or Victorian-style greenhouse, is designed to withstand diverse weather conditions. It offers excellent insulation and longevity and can support various plant species year-round.
What greenhouse is best for winter?
The best greenhouse for winter is an insulated greenhouse, often called a ‘cold greenhouse.’ These structures feature a heating system, double-glazed glass or polycarbonate panels for increased insulation, and adequate ventilation to regulate temperature and humidity. These design elements enable cultivating various plants even in colder temperatures.
