Criteria Used for Evaluation
Materials
One of the major things to ask about a product is the material that was used to construct it. This generally determines whether the product will last for a long period of time or not. Kits are available in different ranges of materials from plastic to powder coated steel that is rust resistant. It is very paramount to note the state of the plastic and the metal.
Though there are different materials to choose from, most people choose metal frames to design a free span interior. The basic structure consists of rafters, side posts, an end wall, side walls, cover, flooring, and horizontal beams that go with the rafters.
Style
Different styles of exist. They are uniquely and typically constructed to give you the maximum satisfaction you deserve. Some are canopy-like; some others act as shelves for the plants. Your choice to purchase solely depends on what it is to be used for.
Freestanding styles feature a curved roof shape. These types offer good lighting and are more affordable to assemble than a peak-roof design. The arched roof features more of a pointed ridge. These types provide more headroom while preventing snow from building up during colder weather. They also cost more.
The furrow style is constructed with a number of spanned houses connected along the length of it. The shared walls are detached, offering more growing space. The ridge and furrow design are applicable to most commercial styles used for vegetable production and floriculture. These are energy-efficient and more affordable.
A retractable roof style is used for crop producing or for basic protection. It comes with the option to open the house partially or completely to allow ventilation and better lighting. Normally used for furrow style, retractable style units have little to no climate control
Size
Size mainly means two things when it comes to your choice: the height, length, width, and weight. You must always ensure that you check to see whether the dimensions are accurate and fit into the description as given by the manufacturer.
Size is also factored by the number of plants you are planning to grow during the cold months when protection from the weather is required. Plants that require warmer weather can continue to grow during both cold and warm months. Shade cloth helps to protect plants from the direct sun. Size also is determined by the affordability of the unit.
Layout a floor plan that includes storage spaces, work areas, walkways, and growing areas. Enough space should be allowed to prevent crops from touching the walls during the cold months and ventilation during the warmer months. Also allow space for watering and rearranging, if applicable.
Brand
A good brand is one that is tested and certified to be in a good working condition. A product should come with complete specifications before packaging and delivering. It is frustrating for a buyer to purchase a product only to find out that it doesn’t match with the description as given by the manufacturer. An outstanding product should have provision for some form of warranty. Money back policies and returns should be in full operation. Additionally, customers should be able to reach the manufacturer easily.
A strong brand positions a product, but they also build value for retails stores that carry them. Industry leadership and innovation are crucial factors when considering a brand. The best ones focus on what the consumers want and access ways to make that happen. Consistency is a key factor of a strong brand, as they dedicate to ensuring long-term relationships with their consumers.
Insulation
If you reside in an area where snow and ice are part of the typical cold weather and you wish to grow crops year round, your product cover needs to be insulted thoroughly. Polycarbonate, which comes in double or triple sheets, is often used for this cause.
The air that lies between the layers offers significant insulation. Polyethylene is “twin-walled” flexible material that is an alternative option to polycarbonate (that is rigid). It provides diffused lighting and superb insulation. In addition, check the snow accumulation rating for the item you are considering. This decreases the risk of collapse during a heavy snowstorm.

Other Factors to Consider
Durability
It is a total waste of time and resources to buy a product that will not last for a long period of time. Even more so, no one wants to buy a product that will get faulty as soon as you use it and has no replacement or is hard to find one.
Polycarbonate is recommended as a glazing due to its transparency (found in eyeglass lenses) and strength (found in bulletproof windows!).
Polycarbonate is treated to be super resistant to the damaging effects of ultraviolet rays, which gives this material a long service life. Most polycarbonate panel manufacturers warrant their panels for 5 to 10 years. Some can be as long as 15 years.
Even though it’s not likely that polycarbonate will last as long as the product itself, they are predicted to last for many years to come. Nevertheless, check out for products that have a warranty and spare parts.
Use
These structures serve a variety of purposes. It helps to grow plants in different weather conditions (cold or heat) and protects them from ultraviolet rays, and from unwanted pests. It stores flowers, herbs, and vegetables in preparation for the next planting season. Listed below are additional uses.
Extend growing your crops
Most vegetables do not ripen because of the frost. With these structures, you are able to cultivate your vegetables and they will mature quickly. As they provide vegetable with warmer temps, chances are that your product will thrive.
Grow plants year-round
Most plants grow the best in certain seasons. Some need a warmer temperature while others need a colder temperature. Depending on the season, plants will grow accordingly. With a structure like this on your side, the plant will grow in all seasons, making crops available throughout the year.
Propagation
These buildings do not offer a natural pollinator for flowers. To bear fruits, you must pollinate plants manually. There are tools and racks to do this. This process allows gardeners a sense of care.
Features
These structures have excellent features.
Shelves
Some have over 6 to 12 tier wired shelves that provide much space for storing plants, herbs, and tomatoes. They are a handy way of keeping resources and tools in their assigned place.
Vents
One of the features considered in our criteria is a way of controlling the temperature. The absence of having a vent means that the house will overheat. Vents are important for providing insects access to pollinate plants. The three basic types of vents are manual, hydraulic, and electric.
Fans
Fans provide two basic purposes. To ventilate to prevent overheating – which damages crops and the protective film. The other is to circulate air inside. Circulation helps to decrease the humidity and gets rid of stagnant air. This process also detracts insects from breeding.
Roll-up Sides
This can be an alternative to manual venting. Roll up sides are found on the entryways. They require a user to operate and can be set up on nearly every style. Gravity holds the structure when rolled down.
Heaters
If your planting requirements are small, having an electric heater will do the job. A propane or natural gas heater is best for larger structures. A fan is used in conjunction to blow the warm air. Smaller gas heaters do not come with a fan. In this case, an interior fan can spread the heat evenly. Area heaters disperse the heat evenly, regardless of where the plants are placed.
Water
Having a water source indoors is ideal, as it is convenient. These come in the form of a hydrant that is freeze proof. These units have an underground connection to protect the water from freezing in cold temperatures. The fixture above ground will drain automatically when the hydrant is set to the closed position. For larger units, more than one hydrant is needed to reduce the amount of hose being used for watering plants.
Electricity
Electricity is another essential feature that you’ll need. This would include smaller units as well. Just think about what electricity can provide for you:
Lights
The most common resource is lighting. Even though it may be used less, it is just as important. Light is needed for nighttime use, and for growing seedlings. Lighting is important for use in larger units where lighting is needed to substitute natural light sources.
Solar Energy
Solar energy can be both active and passive.
Passive Solar Collection
Passive solar involves having large amounts of thermal energy inside the unit that slowly derives energy from the sun and releases it after the sun goes down.
Active Solar Collection
Active solar relies on pumps and fans to spread warmed air or water to and from a solar collector.
Frequently Asked Questions
q: Why do I need one?
There are many reasons why owning one can be a great idea. For starters, you can turn your love for gardening into a full-time passion. Whether you have a lot of hours to spare or just a few seconds a day; these structures are recommended for those with a love for plants. You can grow flowers, organic fresh vegetables, houseplants, bulb plants, exotic flowers, among other types of plants.
You can switch up what you grow each year or cultivate a variety of flowers. If you wish, you can grow different species of plants at the same time. Regardless of which option you decide to do, you can use your plant house to achieve all that. Like pergolas and kiosks, you can get an attractive design that perfectly fits into your landscape. You do not have to be concerned about any landscaping because there are varieties of different shapes and sizes.
You can have an attractive backyard design with a structure placed right in your backyard garden. Like other structures, gardeners can create an area that gives purpose and enhances a visual appeal to your outdoor area at the same time.
q: What style do you need?
As of today, glass remains the most popular choice; however, there are various high-quality horticultural styles of plastics including acrylic, polycarbonate, tedlar, and polyethylene.
When choosing a glazing material, you must factor in the lifetime, the appearance, the double or single glazing, the tightness, and the affordability. Traditional multi-glass glass options are well known for their difficulty to seal. Modern, connecting styles, with huge windows of insulated glass, are mostly very weather-tight.
If you reside in a climate where the ground freezes, a glass option must rest on a permanent foundation, otherwise the frost heave could cause the glass to break. The glass lasts nearly a lifetime, and its transference of light is very high.
With that said, plastic glazing provides some benefits over glass. They are much more forgiving to temperature changes. They are simpler to handle (unbreakable and lighter). They diffuse the incoming sunlight, which avoids damaging the leaves. Finally, they will not be destroyed by a softball or frisbee.
q: Should you choose a modern style or a classic?
You will probably want to be certain that the style or shape is well suited with your home. Even the most stylish Victorian options will not be an appealing addition to a salt pan in New England.
Nordic gardeners must also take in account the snow load when selecting. If the snow does not slide naturally on the roof, you will need to shovel it to protect the glass and allow lighting to enter.
The general shape also affects the interior space and its operation. Make sure the style you select offers enough free height, a work area, a wall surface to display the plants, and a sufficient roof area for ventilation.
q: Freestanding or attached?
Connecting a plant structure directly to your home can come with many benefits, especially if you wish to grow a garden year round. You can come and go to see what's going on at any time of the day or night, regardless of the weather. With having your plants close by, it's easier to remember watering and other maintenance duties. Access to electricity and water is also easy.
On a cold sunny day, an adjacent greenhouse can bring a considerable amount of free heat to your home. But the adjacent houses also have some disadvantages. Without proper ventilation and a way to separate them from the rest of your home, your home will be too hot in the summer and your furnace will be operating day and night during the winter.
A freestanding style is generally more affordable than attached models and are simpler to install. They can be placed directly on the ground. If it is your intention to heat it during the winter, you should consider isolating the foundation up to the frost line. If you use your structure only seasonally, a stand-alone model will be relatively invisible during periods of mid-winter and mid-summer inactivity.
q: Which is preferable? A custom design or a kit?
There are so many companies now offering so many styles and price ranges of different options that there is no reason to start from scratch to design your own. The only exception is if you are building a new house or want to integrate yours into your home's architecture. In this case, it may be wise to seek professional advice. These kits can be as elaborate as a kiosk with turrets built on-site or as simple as a box of plants with material and a roll of polyethylene.
q: Must it be stationed in one place?
Not all can be stationed in one place, as some are portable (lightweight) and can easily be detachable to be moved from one place to another.
