Buying Guide for Best Greenhouse Plastic
People are usually perplexed by the various models of premium grade plastic sheeting for Greenhouses. No worries, we will guide you to pick the perfect product.
Before you buy any greenhouse plastic sheeting, double-check the points on this buying guide.
The greenhouse plastic should be thick. A decent plastic film is 6 mils thick. It also increases its longevity and the capability to resist harsh weather. Any plastic thicker than 6 mils can deprive your plants of their required temperature.
However, if you sacrifice on thickness, you may need to compromise on insulation. Insulation increases with breadth. So, examine the plastic sheeting’s thickness.
Also, the thickness is crucial for extending the life of the greenhouse plastic sheeting.
You can also buy strong and flexible lightweight plastic sheeting to enjoy the extra benefits. So, before you begin, consider the weight of the plastic sheet. Also, the weight of greenhouse plastic sheet affects its strength. It makes the plastic sheet more durable and helps it endure longer.
Not all greenhouse plastics work the same way. While most plastics let in light, some have specific coatings to enhance that ability.
Most greenhouse plastic sheeting protects against UV rays. Notably, UV light isn’t necessarily dangerous to plants as it can be to humans. Instead, UV treated greenhouse plastic sheeting is designed to not degrade over time.
Basically, UV treated greenhouse plastic will survive longer. Non UV treated greenhouse plastic sheeting starts to disintegrate in a year. Most greenhouse plastics contain polyethylene, which rots within a year if the plastic can’t protect itself from UV light.
Infrared greenhouse plastic can increase the warming impact of your greenhouse by keeping radiation from escaping. Infrared greenhouse plastic keeps the interior 20° warmer than the exterior. This greenhouse plastic is great for plants that need high temps to grow.
If the plastic sheet is not transparent enough in the greenhouse, it may not transfer light properly.
Less light implies less heat, which is insufficient for winter plant growth. If the plastic sheeting is not translucent, the sunlight will not reach the plants.
So, when buying a greenhouse plastic sheet, make sure it’s transparent.
Some plastic sheets have three layers, some five. If you want strong plastic sheeting, you must choose a five-layer plastic sheet. This is because the layers of the plastic sheet help trap heat.
These layers also increase the strength of the greenhouse plastic sheet. So, get the five-layer plastic sheet.
Make sure the greenhouse plastic is durable before buying. Since you need this plastic sheeting for a long-term job, it must be sturdy.
Anti Condensation or Anti Drip
Water droplets on the greenhouse plastic layer may block light from entering the greenhouse. The anti-condensation or anti drip feature keeps water droplets off the greenhouse plastic sheeting and allows more light into the greenhouse.
Types of Greenhouse Plastic
Greenhouses are usually made of four different types of plastic. These greenhouse plastics normally last two to three years before needing replacement. Of course, this excludes extreme weather events like hurricanes, tornadoes, hail, and icing.
i. Polyethylene Plastic
Polyethylene plastic comes in two forms: commercial grade for industrial use and utility grade for personal use. Most home centers stock utility grade. Polyethylene greenhouse plastic may be preserved in good condition for a year or two, and it can be mended with a poly repair kit.
ii. Copolymer Plastic
This greenhouse plastic is a step higher than polyethylene, and it can endure up to three years in your greenhouse before becoming brittle and breaking. After some years of freezing and thawing, the copolymer greenhouse plastic will become brittle. It is possible to buy more expensive copolymer plastics that are more durable and simulate glass.
iii. PVC (Polyvinyl Plastic)
PVC is more expensive than the other two, but it is also more durable. The strength of PVC will benefit Greenhouses. If you clean and inspect PVC plastic often, it should last five years.
iv. Polycarbonate Plastic
The most durable greenhouse plastic among all others is polycarbonate. Polycarbonate plastic usually contains twin wall polyethylene plastic. If properly cared for, the twin walls can survive a decade. Polycarbonate plastic also keeps a lot of heat and humidity all year.
Greenhouse Plastic Maintenance Tips
- Check to see if your plastic sheeting is suitable for use as a greenhouse cover
- Do not hesitate when it’s time to say goodbye to your worn-out greenhouse cover
- You can extend the lifespan of your plastic sheeting with small greenhouse repair tape to fix the holes
- At the very least, clean your greenhouse covering once a year.
- Don’t overlook the weight bearing capacity of your greenhouse frame

Can you use 6 mil poly for a greenhouse?
Ans: Many people cover their Greenhouses with 6 mils clear plastic. The most significant asset of the value of 6 mils is their cost effectiveness. You’ll be able to get by with this plastic sheeting.
Does greenhouse plastic block UV rays?
Ans: The majority of greenhouse polymers do block UV rays. However, some farmers willingly let UV light inside their greenhouse enhance certain aspects of plant growth that occur naturally outdoors. Thus, not every type of plastic keeps out UV rays. You can also make windows to regulate it manually.
Does greenhouse plastic have to be clear?
Ans: We recommend that you choose a clear plastic film to wrap the greenhouse because it will allow the most amount of light to pass through and prevent damages to your plants. The amount of sunlight in your greenhouse will be affected if you use colored plastic. During the summer, it’s best to use clear plastic and cover it with shade cloth if necessary.
How do you measure greenhouse plastic?
Ans: This is how you can measure greenhouse plastic-
Add 2 feet to the measurement taken from the ground on one side up and over to the ground on the other side along the edges.
Next, calculate the length of your hoop house from ground to ground and add 2 feet to that amount.
Size up the width of the hoop house and add 2 feet for the ends. Then add 2 feet to the height measured in the center. These are the bare minimums needed to cover both ends.
Determine the extra feet while measuring to avoid causing tension and ripping or stretching the plastic.
How long does greenhouse plastic last?
Ans: When placed properly, good-quality polyethylene greenhouse plastic should survive at least four years, even in high UV environments.
How thick is greenhouse plastic?
Ans: greenhouse sheets come in various thicknesses and widths. The ideal greenhouse plastic sheet would be 6mm thick. The thickness is required to retain heat and keep the greenhouse warm. Thickness also improves the strength of the plastic sheet.
Is green or clear plastic better for a greenhouse?
Ans: Green greenhouse plastic cover reflects a substantial percentage of green waves while allowing other light spectrums to pass. The spectrum colors are red, orange, yellow, green, blue, indigo, and violet.
Plants require blue waves for growth and maturation and red waves for blooming and production. They absorb much less green light. Therefore it reflects back into our eyes, giving the illusion of green foliage.
Also, during photosynthesis, the pigment chlorophyll only absorbs blue and red light while reflecting green light. In essence, green plastic filters out green light, whereas clear plastic lets in the whole light spectrum inside the greenhouse construction.
Should I use clear or white greenhouse plastic?
White greenhouse plastic covers help in light diffusion but overheat. Diffused light reaches lower and upper leaves. This increases photosynthesis.
Direct sunlight into the building heats the soil and encourages seed development. Clear plastic is only for greenhouse seed germination and transplanting.
Planting seedlings in direct sunlight encourages germination and growth. Clear covers like glass, polycarbonate and acrylic plastic are ideal.
What is the best plastic to use for a greenhouse?
Ans: Amazon.com has a multitude of greenhouse plastic films. Farm plastic, A&A, and Suncover are the best examples for you.
