Greenhouses are buildings, whether small or large, which provide optimal conditions for the growth of various types of plants, including vegetables and flowers. These structures also come in different sizes, and they can be made in a simple way or high-tech.

The high-tech greenhouses have numerous gardening advancements to them, such as ventilation & heating systems, as well as devices that work to boost the level of carbon dioxide in the atmosphere.


These houses are reasonably priced and are made from different durable materials that can last for years. Structures made from the best greenhouse plastic are appreciated more by the modern-age farmer.

They, however, come in different forms and brands. Picking the best one might be an overwhelming experience for an average shopper, especially for someone who is just starting.

This post seeks to cover all the nitty-gritty surrounding plastic greenhouses, with a comprehensive buyer’s guide and a review of some of the best plastics for greenhouses.

Benefits Of A Greenhouse

Owning a greenhouse has the potential to turn your gardening hobby into pure passion. This is because of the numerous advantages that having a greenhouse comes with.

It is beneficial to everyone who loves plants, regardless of the time you spend farming daily or weekly. Let’s dive into some of the most significant benefits of owning a greenhouse:

1. Multiple Uses

One of the biggest advantages of owning a greenhouse is its flexibility and the ability to support diverse flora. Some of the plants which do so well in greenhouses are organic vegetables, exotic plants, flowers, bulb plants, and all types of seedlings.

You can either grow a variety of produce at the same time if you wish to or you can interchange them after every year or planting season. The owner has the full choice of whatever they want to be grown under greenhouse conditions, and the list to pick from is not limited.

2. An All-In-One Gardening Venue

One of the major concerns many people have when farming various plants is where to keep their equipment. A greenhouse offers you space to store your products under the right conditions until when you will next need them.

You don’t have to spend extra cash building a garden shed, as you will have enough room not only to plant your vegetables and flowers, but also store your supplies, tools, and other gardening equipment.

3. Consistent Farming

A greenhouse helps farmers to avoid the troubles others undergo due to ideal planting seasons, extreme weather conditions, etc. As long as you have all that is required for greenhouse gardening, you can evade and ignore all the problems which arise due to excessive rainfall, drought, scorching sun, etc. You will have the ability to plant anything, regardless of the season.

4. Plant Protection

One of the biggest issues farmers face is, as stated above, extreme weather conditions and severe pest infestation. Seasonal pests such as locusts, spider mites, and tent caterpillars are the most common crooks when it comes to destroying plants.

Birds also top this list of some of the animals which tamper with the growth of various plants. Taking all these into consideration, it is no brainer that a greenhouse helps prevent all these damages from occurring by providing a protective cover to your plants.

5. Optimum Environment For Gardening

If you are a seasoned farmer, you will understand that the majority of plants, especially vegetables and flowers require a warm and humid environment for them to thrive. Structures made from the best greenhouse plastic ensures that the plants get these ideal conditions for them to grow.

The main objective of greenhouses is to ensure that a reasonable amount of heat and water vapor is secured within the structure.

6. All-Season Gardening

With a greenhouse, you are in charge of not only what to grow but also when to do so. You do not have to undergo the long waits for the perfect planting season for the different types of plants. Moreover, you are in control of the temperatures and watering, so you can plant earlier or soon after the others have planted.

7. Save Money

Having a greenhouse can save you lots of money in many ways. For starters, you may end up spending a lot in the purchase of seedlings to grow in your standard garden. However, due to the many adverse conditions which prevent the plants from thriving, you may be forced to purchase more.

Since these plants grow in a greenhouse, the rates of survival increase; hence, there will be no need for you to buy the seedlings numerous times.

8. Makes You Money

If your greenhouse is large enough, you can sell some of the products you grow to make extra money. You do not even have to market your products far and wide as your immediate neighbors can be one of your key customers.

9. Seamless Customization

Greenhouses come in different types and shapes. When building using the best plastic for a greenhouse, you can easily customize your structure to how you want it to be and make it take care of whatever plants you have in mind.

You can easily decide on how many doors you want, the placement of plants, where the storage area will be, among many others.

10. Grow Plants Free From Toxic Pesticides

Plants grown in greenhouses, especially fruits and vegetables, are more preferred as they are more organic, unlike other types of plants. Many commercially raised crops are exposed to too many toxic pesticides, which can be avoided when one uses a greenhouse instead.

These are but a few reasons why you should start looking for a greenhouse for your gardening needs. However, it should be noted that as much as these structures provide optimal conditions for the growth of plants, it is your responsibility to provide water. This is because the greenhouse is enclosed, and rainwater does not penetrate through the roof or walls.

11. Understanding Greenhouse Plastic

A greenhouse is a temporary structure that can be easily customized, taken down, or moved to a different location. This is made possible due to the material used in its construction – plastic.

Using a solid sheet panel of glass, polyethylene, or acrylic means that the structure is permanent, and making customizations or moving it from the current location becomes tricky.

Furthermore, the types of plastic you decide to put on your greenhouse have varied impacts on your plants and the amount of labor required during installation and replacement.
So, what exactly is meant by greenhouse plastic?

Plastic-based greenhouses are much easier to build, lighter, and cost much less money when making, than glass-based models. Just like the glass would, the plastic is used to secure the heat and humidity inside the structure to provide optimal conditions for the plants to grow, no matter the weather or season.

However, not all types of plastic can be used to build greenhouses. The best plastic for a greenhouse is much more durable than the standard ones.

Using regular plastic for a greenhouse brings more damage than good to the functioning of the structure. Besides, its ends tend to fray at times, and should there be any small cuts made, it can gradually grow into a sizeable noticeable tear.

Standard plastics are also not made to withstand the elements when exposed to extreme conditions. Greenhouse plastic is made by knitting it together rather than making it out of a solid sheet; hence, it becomes more durable and can withstand extreme weather conditions and resist tear.

Relationship Between Greenhouse Plastic And The Climate

There are many options when trying to select the best plastic for a greenhouse. However, before even delving into finding out the best type for you, it is paramount to take the climate of your area into consideration.

For someone who resides in an area where the temperatures are generally cold, wet winters, but are without hard frosts, a lightweight greenhouse plastic would be ideal for them. Such climates are suitable for planting, even without a greenhouse. However, a greenhouse is recommended for early seed starting.

If you frequently receive hard frosts in a wet, cold region, you might need to get a thicker plastic. The same case applies when there is snow in your area, as it should be able to slide off upon contact with the plastic easily.

Furthermore, the plastic ought to be thick enough to keep off the cold air from affecting the plants. It is essential that even if you are looking for a thick plastic for your greenhouse, it should still allow the winter sunlight to penetrate and reach the plants.

Lastly, for an area that frequently gets heavy snow, the average weight of the snowpack should be considered. If the snow does not fall off on its own, you may have to manually clear it to make room for the sunlight to penetrate. The warmth inside is still a requirement, so something which is heavily insulated and is rigid is probably your best shot.

Types Of Greenhouse Plastic

There are four standard kinds of greenhouse plastic. They are all highly durable and can take you anywhere between two and three years without having to change them. They can all get affected by certain extremities such as tornadoes, frosting, hail, hurricanes, among other factors that may make their lifespan shorter.

All in all, to know which the best greenhouse plastic for you is, it is vital to understand the various types you can choose from:

1. Polyethylene

Polyethylene is the most popular type of greenhouse plastic as the majority of people use it and numerous reasons back this. For starters, it is relatively inexpensive compared to other types of plastic. Polyethylene is made from a material that is readily available and is not as hard to repair.

When purchasing this type of product, it is recommended that you look for one which has been branded as ‘greenhouse plastic’ or ‘agricultural plastic.’ This is because there are other utility-grade Polyethylenes which may not be as practical and durable.

The main problem associated with such plastic is that the services you get from it are directly proportional to the amount of money you pay for it. The fact that it is inexpensive may have its durability compromised.

Just like glass greenhouses would, some of these polyethylene plastic greenhouses have been made with specific chemical properties, which ensure that condensation levels are reduced. Furthermore, they can reflect radiated heat back into the structure, making them more energy-efficient.

It is also important to note that ultraviolet light can quickly degrade a polyethylene film. That is why it is highly recommended that you get one that has UV protection embedded in it.

2. Copolymer Plastic

Next up on the list is Copolymer plastic. It is a notch higher than polyethylene in regards to its durability and strength. The only problem with such plastic is that it tends to get frail and brittle after about three years and can be subject to breakage.

However, if you have some extra cash from your budget, you might opt for a pricier version, which is as clear as glass, lasts longer, but you might have to dig deeper into your pocket.

3. Polyvinyl plastic

Polyvinyl plastic is more expensive compared to polyethylene. This can be attributed to the fact that it is heavier and has a longer life cycle. Polyvinyl Chloride (PVC) is the same plastic that is used in the manufacture of pipes, and that is why with proper care and cleaning, you may not have to replace it before five years’ end.

4. Polycarbonate Plastic

Polycarbonate plastic is the most durable and of course, the most expensive of all greenhouse plastic. It can be described as a double-wall polyethylene plastic due to its heaviness.

It is ideal for those who wish to have something a bit rigid but not made of either glass or acrylic. Such materials provide the greenhouse with more insulation while still allowing enough light to penetrate.

Due to their rigidity, polycarbonate plastic greenhouses last longer – up to a decade without any wear or tear. Furthermore, they are probably the best option for someone who lives in very cold areas can have.

How To Choose The Right Greenhouse Plastic

Choosing the best greenhouse plastic is not an easy task, as there are too many options available on the market. If you are starting, you should not worry much as there are means you can use to narrow down your list.

All types of plastic might not work for you, depending on various factors, such as your needs and the weather. That said, take a look at some of the factors you need to consider before settling on a particular type of greenhouse plastic or brand.

1. Durability

The material which makes the plastic is vital when preparing to build your greenhouse. For how long do you intend to keep it? Would you still need to plant the next season, or it is just a one-time project? How is the weather in your region? Is it too extreme (either hot or cold), or is it only moderate?

These are a few questions you need to ask yourself while in pursuit of the best plastic for greenhouses. This is because they all point to one thing – the durability of the material. Plastics such as polyethylene naturally degrade over time as they are exposed to sunlight and heat, regardless of how durable they appear at first.

If you want to keep the structure with you for a somewhat extended period, you should narrow down your list to other plastics such as polyvinyl or polycarbonate.

2. Thickness

As a rule of thumb, greenhouse plastic should have a thickness of at least six millimeters. Plastic that is not thick enough would not last you the entire planting season, let alone various seasons. More thickness would be required for better insulation.

3. Transparency

While this might sound axiomatic to you, but it is a rather important factor to consider. Colored greenhouse plastic (especially green ones) are no longer familiar to many farmers. This is because transparent plastic is much better for the growth of plants.

Sunlight will have some trouble reaching the plants if the plastic is colored for photosynthesis to take place.

However, transparency isn’t a primary concern today as the majority of greenhouse plastic is transparent, but on various levels. The biggest issue is finding the correct balance between the transparency of the plastic and how thick it is. One might be considered at the expense of the other, and so it is vital to have them both at optimal levels.

4. Weight

Thick plastic sheets are more durable and are, by default, heavier. You should understand that the plastic sheet does not provide any structural integrity, meaning that all the weight falls on the frames of the greenhouse.

Before you set out to purchase the plastic, first consider how sturdy the structures are and whether or not they will support your preferred plastic.

5. Condensation Control

Many factors might reduce the effectiveness of your greenhouse. There is an imbalance caused by the outside cold weather and the warm conditions inside the greenhouse during winter. If this happens, condensation might take place in the inner surface of your greenhouse plastic sheet.

These condensate droplets bring with them various disadvantages, such as inhibiting the sunlight from reaching the plants. They might also fall on the plants disturbing the excellent ecosystem you had initially created.

At other times, these droplets falling on your plants might also be responsible for the growth of mildew, which will not end well for your plants.

When shopping, it is advisable that you look for plastic that has a hydrophilic radical. An example of such is -COOH (carboxylic acid), which aids in the prevention of condensates from falling onto the plants.

They are instead made to stick to the surface and evaporate easily, leaving the plastic clear. Plastics that have hydrophobic radicals such as the ones available in the -CH groups should be avoided as they repel the droplets.

6. Heat Loss And Gain

This is a feature to look out for, especially when you live in an area with extreme temperatures – both cold and hot. If you are in a cold area or planning on using the greenhouse during winter, plastic insulation layers and additives would save you a lot. Some advanced plastics have infrared insulation layers which help in keeping the heat inside.

For hot areas and during summers, it would be recommended to protect your plants from overheating. You would need plastic that would block some infrared spectrum, keeping your plants safe.

7. Layers

Greenhouse plastic can be single, double, or triple-layered. Whatever you choose, it should correlate with your climate and also what you wish to grow. Individual layers are just fine, but double layers come in handy when you are experiencing extreme weather.

They also help when you are trying to grow very sensitive plants that depend on an optimal environment to survive. Having a greenhouse built and maintained is not an easy task, but all this can be made even easier for you if you have the right brand.

Numerous brands are depicting themselves to have the best plastic for greenhouses, but their reviews speak contrary to what they advertise.

It is also hard finding honest reviews on the internet, and that is why you ought to look for unbiased review sites, such as this one, which will guide you to nothing short of the best. Listed below is a list of the fifteen best greenhouse plastic you can choose from.
