Greenhouses can be a real blessing for those with a green thumb. And building one with a kit saves you money and time. In this article, we’ll help you decide which is the best greenhouse kit for your needs from among the many options available in the market.

Best Greenhouse Kit

Whether you’re a gifted gardener or just love being surrounded by plants, there are many reasons why you would want to have a greenhouse. Having a greenhouse in the yard can aid in growing your own food, or can simply serve as a peaceful retreat after a tiring week. But they can cost you a lot of money. In the United States, building a greenhouse can cost anywhere from $7,000 to $25,000. The expenses will vary depending on factors like the size of the greenhouse, materials used, excavation, and permits, among others. That’s why you should put in a lot of effort into researching the best greenhouse options available today.

While greenhouses can be quite expensive to set up from the scratch, a greenhouse kit (also commonly known as a ‘greenhouse-in-a-box’) allows for a more economical approach, especially for a beginner. So now that we have an idea of the costs involved, let’s see how to choose the best greenhouse kit for the greenhouse of your dreams:

What are the most common types of greenhouses?

Greenhouses come in various styles, materials and makes to suit different growing conditions and environments. The following YouTube video gives an excellent overview of the many styles of greenhouses available today:

Now that you have an idea of some of the greenhouses styles, I’d like to discuss some of the more common ones that can be purchased as kits:

1. Round Arch Greenhouse

These installations are also known as the “round greenhouse” by wholesale greenhouse kit dealers. They require no foundation and is most often covered with plastic film. This is ideal for hobby farmers or those who don’t have much space on their property to set up larger greenhouses.

Sizes available in wholesale kits: from about 12’ x 12’ to about 14’ x 28.’

Pros of Round Arch Greenhouse:

  • Common and easy to set up
  • Excellent in mild climates

Cons of Round Arch Greenhouse:

  • Generally not strong enough to withstand high winds or heavy snows
  • Depending on your region, they can be costly to heat in the winter

2. Gothic Arch Greenhouse

Gothic greenhouses come in an arch design with narrow upper areas gradually expanding towards a larger base. Smaller buildings are about 8 inches tall, but they can range up to 10 inches in overall height.

They are usually spacious and may have trusses or crossbars added to help strengthen their frame. Some people even add a center pole to their greenhouses in the winter, though this can interfere with the plants getting enough light. These types of greenhouses are also available in kits and can be easily erected in less spacious areas.

Sizes available in wholesale greenhouse kits: from about 14’ x 16’ to about 18’ x 36.’

Pros of a Gothic Arch Greenhouse:

  • Stronger in design than round arch greenhouses
  • Do not require a foundation
  • Can expand to a large size
  • Cheaper to heat in winter — depending on the cover and frame materials
  • Less prone to winter damage as snow tends to slide off the sides

Cons of a Gothic Arch Greenhouse:

  • Difficult to construct, a problem that can be mitigated with the correct wholesale greenhouse kit

3. Traditional Greenhouse

When many people hear the word “greenhouse,” they picture a glassed-in building filled with flowers and surrounded by trees. This is the traditional or “engineered” greenhouse. These buildings are usually very sturdy and covered in plastic, plexiglass or even pure glass.

These greenhouses are not commonly found in wholesale kits. If available, they are generally smaller than the other styles. They are more expensive also.

Sizes available in wholesale greenhouse kits: usually between 6’ x 8’ and 10’ x 12.’

Pros of a Traditional Greenhouse:

  • A stronger frame that’s permanent in nature
  • Offers good air circulation
  • Excellent lighting

Cons of a Traditional Greenhouse:

  • Needs a stable foundation
  • Can be expensive to heat, depending on frame and cover materials

4. Gothic-Traditional Greenhouse

The Gothic traditional greenhouse combines some of the best features of both the Gothic arch and traditional designs. These may or may not need a foundation, depending on the size of the building and are often built with bent tubing. They may be covered with plastic film or plastic panels.

Sizes available in wholesale greenhouse kits: available in a variety of sizes

Pros of a Gothic-Traditional Greenhouse:

  • Due to their construction, they are easy to vent for air circulation all year.
  • Heating costs will vary based on your region’s climate, but these types of greenhouses tend to do better in cooler climates than the round arch or Gothic arch types.

5. Sunroom Greenhouses

A Sunroom greenhouse or passive solar greenhouse is one that forms an extension of the owner’s home. They are attached to the wall of a house. Usually, these greenhouses are covered in glass or polycarbonate panels and should only be used for hobby or family farming and not commercial growing of plants.

Sizes available in wholesale greenhouse kits: from about 6’ x 8’ up to a whole side of the house or an 8’ x 20’ room.

Pros of Sunroom Greenhouses:

  • Easy access to water, electricity and resources

Cons of Sunroom Greenhouses:

  • Sunlight may become an issue if the shadow of the house falls on the greenhouse.
  • Temperature control is more difficult.

Types of greenhouse based on shape

If you have a large yard, you may want to build a traditional greenhouse with a rectangular shape, metal frame and a pitched roof. It offers lots of growing space for your plants aside from maximizing light. Moreover, the traditional greenhouse has a classic design that blends well with its surroundings.

You can also opt for a barn which has a similar shape to that of the traditional greenhouse but has a higher headroom. It is thus more appropriate for growing taller plants as well as vines and climbers. It also doesn’t require any base, which makes it easier to build than the traditional greenhouse.

Another type of greenhouse design that you may want to build is the heptagonal greenhouse. It is best suited for smaller gardens because it takes up minimal floor space while still giving a place to nourish your plants.

If you don’t really have enough space for a traditional greenhouse, you can try to build a window-mounted greenhouse or go with a highly recommended mini-greenhouse. As the name suggests, it is attached outside the window. Ideally, these greenhouses should be on the south or east side. The challenge, however, is to maintain a uniform temperature in this type of greenhouse.

Choosing the best greenhouse kit hack #4 — Greenhouse frames

Another factor that you must consider when choosing the best greenhouse kit is the frame needed to support the building. It goes without saying that your greenhouse is only as good as the frame it is built upon. The frame is the weight-bearing skeleton of the entire building and you need to choose it carefully. If you intend to move your greenhouse occasionally, you will need a temporary lighter frame.

If you have decided to go for a permanent structure such as a traditional greenhouse, then a heavier material will not only suit your needs, but will also add visual appeal. The cost of setting up a permanent greenhouse with a kit will be slightly lesser than if set up from scratch.

Types of greenhouses based on frame

When choosing a greenhouse kit, you should consider the durability and functionality of its frame. Greenhouse kit frames are made of PVC, steel or wood. There are pros and cons of each frame type.

Wood is a bit more difficult to construct although it is more attractive than steel frames. Steel frames, however, are maintenance-free and can last forever. But a steel frame is less energy efficient compared to wood.

You can also opt for a hoop house frame made from a series of pipe hoops. These are easier to build, but the problem is that they aren’t as durable as steel or wood frames. Let’s look at each one of them in detail:

1. PVC-framed greenhouses

Also known as “hoop houses,” PVC greenhouses are great for a temporary spring and summer growing seasons. These lightweight frames are made of plastic pipes that resemble hoops.


  • Extremely lightweight and portable
  • Generally the least expensive greenhouse frame material in the market
  • Rust and rot-free


  • Vulnerable to high winds
  • The overall structure isn’t very strong. Heavy icing or snow build-up can destroy the greenhouse very quickly. So this type of frame is not recommended for colder regions.
  • If these frames are not UV treated, they will warp from constant sun exposure.

Other plastic and resin frames are also good choices as they can withstand rain and light snow. Like PVC, plastic and resin will not rust or rot. These types of greenhouses are easily found in kits.

2. Steel-framed greenhouses

A steel-framed greenhouse is a work of art. They are great options for permanent greenhouses and frequently come in kits with detailed installation guides. They are very strong and long-lasting but are usually expensive

3. Wood-based greenhouses

Strong woods such as cedar and redwood are commonly used for most traditional greenhouse frames. Like steel, wood frames are meant for permanent buildings. Most wood that is used in building greenhouses today is pressure-treated to protect it against mold and warping. But check with the manufacturer of your kit to ensure that this process has taken place.

Wood greenhouse kits come in a variety of styles and sizes. For example, you can find Wooden Greenhouse kits in sizes from 8’ x 8’ to larger than the average garden shed.

Choosing the best greenhouse kit hack #5 — What do I cover my greenhouse with?

Covering or ‘glazing’ your greenhouse correctly plays a big part in lengthening its life. There are many glazing options like polyethylene which is available as sheet film or woven plastic. Polyethylene is cheap, although it doesn’t offer enough insulation. You can also opt for glass, which is the most durable of all glazing types, although it is more difficult to cut and handle when compared to plastic glazing. Fiberglass is another option, preferred for its strength and ease in cutting and handling.

There are other factors that you have to consider. If you live in a windy area, you will have to buy strong glazing. Polyethylene and hoop houses aren’t ideal in this regard as they are very susceptible to wind damage. You’d want fiberglass or multi-layer polycarbonate instead.

Common covering materials used in when setting up these buildings with greenhouse kits are:

1. Polyethylene Film — The Least Expensive Greenhouse Cover

Polyethylene film can be placed on your greenhouse in either a single layer or double. It comes in both panels and rolls. There are different grades of polyethylene film, all based on the expected life of the material which vary from 1 to 4 years. This is the least expensive type of greenhouse covering.

2. Polycarbonate Greenhouses Covers

Polycarbonate greenhouse coverings are available in either corrugated or multi-wall types. Both types are resistant to hail damage and are coated with UV protectant on the outer surfaces. They come in anti-condensation varieties as well. Some types of polycarbonate coverings come with a 10-year manufacturer’s warranty.

3. Solexx Greenhouse Covers

Solexx greenhouse covering is a mixture of PVC, steel and tubing – a mixture that works great for many types of climates. The panels are flexible and easy to cut, move and position around the greenhouse.

4. Traditional Glass Greenhouse Covering

Glass is the “traditional” greenhouse covering. And its the reason people still call the process of covering a greenhouse as “glazing.” Glass is not just the most expensive cover, but also the most economical one in the long run. It can be purchased as double strength or insulated and has the longest lifetime of any other material, generally lasting 25 years or more.

Glass is highly UV resistant. When insulated, it will keep you from losing heat in your greenhouse for many years.

Choosing the best greenhouse kit hack #6 —What flooring should I use?

The flooring you pick for your greenhouse is largely based personal preference. Some people like rubber mats while others prefer a packed-dirt floor. Whether you choose plastic, rubber, stone or dirt, consider the water run-off, ease of cleaning and overall wear-and-tear to help decide the best flooring for your greenhouse.

Greenhouse Flooring solutions has an excellent article on the different types of flooring available right here – Greenhouse heating, flooring and staging.

Choosing the best greenhouse kit hack #7 — Heating and cooling your greenhouse

When using a greenhouse kit, ensuring correct temperature control is of paramount importance. The minimum temperature that most flowers, produce and fruit can withstand is about 55ºF. The best greenhouse kit should provide for sufficient ventilation for your plants.

It should also account for the type of heating you will provide for the greenhouse. There are two widely available choices for heating your greenhouse — electricity and natural gas.

This short video by Texas-based Doodley Dee Farm can help you with your heating and cooling your greenhouse decisions:

Cooling and ensuring good air circulation in your greenhouse can be done by fans or by vents. Vents can be built right into the covering, especially if you are using plastic film or polycarbonate. During spring and summer, glass windows and doors can be left open.

Choosing the best greenhouse kit hack #8 — Where to build your greenhouse

Have you decided where you are going to set up the greenhouse? Consider these tips before installing your greenhouse structure:

Greenhouse Location

Location is important for more than just ensuring your growing plants get enough light every day. You must consider your own needs as well – Can you get back and forth easily to your greenhouse at least twice a day?

Your plants will need to be watered as well. So consider the locations of nearby hoses and places where new water lines can be run.

Is the path from your house to the greenhouse level and easy to push a wheel barrel along? Or is it rocky and difficult to walk on? Maybe it is easy on dry days but becomes a swamp in the rain? All these scenarios can be avoided with proper placement. If getting to your greenhouse is difficult in the best weather, you aren’t going to want to hang out in it in the worst.

Also, the slope of the frame affects how dead leaves, snow and ice accumulate on the greenhouse. You might want to think about this technicality before finalizing on a greenhouse kit.


Your greenhouse should be able to catch as much available sunlight as possible. If you live in a more northern region, building it near a windbreak that won’t create too many shadows is ideal. Pick a greenhouse kit which offers coverings that allow for sufficient sunlight to enter the greenhouse.

Greenhouse Drainage

The base for your greenhouse should be slightly sloped. Or if that is not possible, drainage pipes should be installed to take water away from the structure. Pipes can also help deter burrowing rodents. The greenhouse kit should allow for the constriction of pipes and drains.

Cold weather

The door of your greenhouse should always be built away from the prevailing wind of your region to avoid losing too much heat in the winter. Plants that are suddenly exposed to cold can go into shock and die.

Choosing a good quality covering and adding sufficient heating can mitigate these issues.

Electricity and lighting

Another consideration when choosing the right greenhouse kit is electricity. Do you have power sockets near you that can take on extra load? Does the greenhouse pose any electrification dangers? You may also wish to install lighting so that you can work with your plants throughout the year.

Consider hiring a professional to assess these matters. An electrician can also help you decide whether electrical or natural gas heating will be best for your greenhouse.

The following article helps explain how to choose the location to set up greenhouses using kits in greater detail —

Choosing the best greenhouse kit hack #9 — Location and regulatory permits

Before purchasing a wholesale greenhouse kit, it’ll be a good idea to become familiar with your local laws regarding building sites.

There are very few greenhouses that can be properly built without a foundation being laid. As many localities regard a building with a foundation as an “improvement,” you may need to have a license to build it on your property.

Other factors that come to play when choosing the best greenhouse kit

Greenhouse panels

Panels made using film, plastic and plexiglass are cheap and durable options as you won’t incur the large cost of replacement usually found in glass. Most panels insulate well and let excess compaction run off. They won’t imbibe any water which causes issues such as mold and mildew. They also spread sunlight very efficiently; even in direct sunlight, they will disperse rays throughout the structure. Consider these features also when evaluating the best greenhouse kits in the market.

Greenhouse base

Another consideration when choosing the best greenhouse kit is deciding the base you need. The base of a greenhouse can be made of wood, concrete, galvanized steel or aluminum. There are a lot of considerations when choosing a greenhouse base, like insulation, drainage and sturdy construction.

  • Wood is an excellent base for a greenhouse because it is strong enough to support the hefty structure. In terms of cost, it is also cheaper compared to steel or concrete. But it can be prone to rotting. You don’t want to use treated woods for the greenhouse base because it can release harmful chemicals to the soil which can hamper the growth of your plants. Instead, look for naturally resistant wood types like redwood, cedar and cypress.
  • Concrete is the best material if you have a permanent greenhouse. It can last for a long time, and need not be replaced or repaired. Concrete is sturdy and can support heavy materials ranging from wood to glass. The downside is that it is obviously a lot more expensive when compared to wood and doesn’t allow for contact with the ground. The concrete slab foundation would also need drains to be installed so as to prevent water build up which can result in mosquitoes thriving inside the greenhouse.
    Another problem with concrete is that it can require hard labor, as there is a need to dig a level area aside from adding gravel and sub-floor materials. Concrete base isn’t exactly ideal if you have limited DIY skills.
  • Galvanized steel is like concrete as it is very strong. It is also similar to wood as far as price is concerned and is rather cheap. Most greenhouse kits have frames made of galvanized steel. They are durable and long lasting. Moreover, they do not pose much shadows, thus blocking sunlight to plants.
  • Aluminum is also strong, but not in the same level as steel and concrete. It’s slightly more expensive than wood, easier to maintain and perhaps the longest-lasting base material as it won’t rot or rust. Aluminum won’t also break down from UV rays.
