Everything You Need To Know About Greenhouse Plastic Sheeting

Struggling to decide on the best greenhouse plastic sheeting? This can be a daunting task because there are so many options and so many diverse opinions on the top.

I found this extremely confusing when I was first learning about plastic coverings and how they impact temperatures in your greenhouse.

That’s why – This article will guide you through everything that I’ve discovered about the topic of greenhouse plastic.

Let’s uncover what makes this covering so popular among seasoned and novice gardeners alike!

What is Greenhouse Plastic Sheeting?

Greenhouse plastic sheeting is a flexible and durable material used as a covering for greenhouses. It helps control temperature, protect plants, and provides increased warmth and humidity.


Greenhouse plastic sheeting is a type of protective covering used in the construction of greenhouses. It’s typically made from polyethylene, a durable and flexible material known for its affordability.

This type of plastic can be stretched over a greenhouse frame to complete assembly, creating an insulated environment conducive for plant growth. Some versions feature UV resistance to protect plants from harmful solar rays.

The primary function of this sheeting is providing temperature control and protection against wind, frost, and dust for plants inside the greenhouse structure.


Greenhouse plastic sheeting is used primarily to cover the structure and form a protective barrier for plants inside. It shields delicate vegetation from harsh weather conditions such as frost, wind, and dust while providing essential warmth and humidity.

Greenhouse plastic helps maintain consistent temperatures in different climates, a crucial aspect of plant growth and survival. UV-resistant versions offer added protection from harmful sun rays.

Beyond its use in standard greenhouses, this flexible material also lends itself well to DIY gardening projects such as mini greenhouses or cold frames due to its easy attachment capabilities.

It’s an affordable option that addresses diverse horticultural needs whether it be commercial farming or home gardening endeavors.

Types of Greenhouse Plastic Sheeting

There are three main types of greenhouse plastic sheeting: clear, white, and heavy-duty.

Clear plastic sheeting

Clear plastic sheeting is a popular choice for greenhouse coverings due to its many beneficial attributes. This type of covering permits maximum light transmission, crucial for plant growth and health.

The transparency of clear plastic sheeting also makes it easy for gardeners to monitor their plants without disturbing the internal environment. It’s favored for its affordability and flexibility, easily stretched over various greenhouse frame designs.

UV-resistant options are available, providing protection against harmful sun rays that can degrade materials over time. Despite its seemingly delicate appearance, clear plastic sheeting offers impressive durability, withstanding diverse weather conditions while safeguarding your plants from wind and frost damage.

White plastic sheeting

White plastic sheeting is a popular option for greenhouse coverings. It is known for its ability to maintain a consistent temperature inside the greenhouse, creating an ideal environment for plants.

The white color reflects sunlight, helping to prevent excessive heat build-up during hot weather. This helps protect delicate plants from wilting or scorching in high temperatures. Additionally, white plastic sheeting provides diffused light instead of direct sunlight, which can help promote even growth and reduce the risk of sunburn on plant leaves.

You can also get double sided sheeting with one black side and one white side to reflect the light back onto your plants (white side) and create a light resistant area and keep warming (black side).

With its durability and ability to control temperature, white plastic sheeting is a reliable choice for any greenhouse owner looking to create an optimal growing environment.

Heavy-duty plastic sheeting

Heavy-duty plastic sheeting is a popular option for greenhouse coverings that require extra strength and durability. Made from high-quality polyethylene plastic, this type of sheeting is designed to withstand harsh weather conditions, including strong winds and heavy snowfall.

Its thick construction provides added protection for plants, ensuring they remain safe and secure inside the greenhouse. Additionally, heavy-duty plastic sheeting often comes with UV resistance properties, protecting plants from harmful sun rays while maintaining optimal light transmission.

With its superior strength and longevity, heavy-duty plastic sheeting is an excellent choice for greenhouse owners looking for dependable and long-lasting coverings.

Key features to consider when choosing heavy-duty plastic sheeting include thickness and UV resistance. Thicker sheets provide better insulation and are more resistant to tears or punctures.

Increased warmth and humidity

Greenhouse plastic sheeting plays a crucial role in creating the optimal environment for plant growth by increasing warmth and humidity. The plastic acts as a barrier, trapping heat inside the greenhouse and preventing it from escaping.

This helps to maintain higher temperatures during colder seasons and even at night when external temperatures drop. The increased warmth promotes plant growth and allows for extended growing seasons.

Additionally, the plastic sheeting helps to retain moisture within the greenhouse, leading to higher humidity levels that are beneficial for many plants. It creates a microclimate that enables plants to thrive by providing them with the ideal conditions they need to flourish.

Maintenance and Care Tips

Regular cleaning and inspection of the greenhouse plastic sheeting is essential to ensure its longevity and effectiveness in protecting plants.

Regular cleaning and inspection

Regular cleaning and inspection are essential for maintaining the longevity and effectiveness of greenhouse plastic sheeting. Over time, dirt, dust, and debris can accumulate on the surface of the plastic, reducing light transmission and hindering plant growth.

By regularly cleaning the sheeting with a mild detergent or soap solution and scrubbing gently with a soft brush or cloth, you can ensure that maximum light reaches your plants. Additionally, performing regular inspections allows you to identify any tears, holes, or damage in the plastic and take prompt action to repair or replace it as needed.

This proactive approach helps to prevent further damage and ensures that your greenhouse remains well-protected against wind, frost, and dust while providing optimal growing conditions for your plants.

Proper storage during off-season

To ensure the longevity of your greenhouse plastic sheeting, proper storage during the off-season is essential. When the growing season is over and you no longer need to use the plastic sheeting, it’s important to store it correctly.

Start by cleaning the sheeting thoroughly to remove any dirt or debris that could potentially damage it during storage. Once clean, roll up the plastic tightly and secure it with zip ties or bungee cords to prevent unraveling.

Store the rolled-up sheeting in a cool, dry place away from direct sunlight and extreme temperatures. This will help protect it from UV damage and other environmental factors that can degrade its quality over time.

Replacing damaged sheeting

When your greenhouse plastic sheeting becomes damaged, it is important to replace it promptly to ensure optimal growing conditions for your plants. Regular inspection is key to identifying any tears, holes, or wear and tear in the sheeting.

Once damage is spotted, carefully remove the damaged section and replace it with a new piece of greenhouse plastic. This will maintain the integrity of the structure and prevent pests or harmful elements from entering.

By replacing damaged sheeting in a timely manner, you can continue to provide a protected environment for your plants to thrive.
