How to Choose the Best Greenhouse Plastic

It is imperative to pay attention to technical aspects while choosing the greenhouse plastic. After all, you will be spending a lot of time tending to your beautiful plants, and a choice of poor greenhouse plastic should not ruin your hard work in the garden.

Durability

There are several varieties of greenhouse plastics, but the ones with 5-layer film technology in greenhouse plastics give additional strength and longevity to the plastic along with the UVA protection to plants. The five-layer technology will provide not only high mechanical strength but also a lot of flexibility to cover the plants appropriately.

Since your greenhouse is going to be subjected to a lot of extreme weather conditions, you ought to take the durability into account. This will help your greenhouse to sustain torrential rains, scorching heat, strong winds, heavy snowfalls or hailstorms depending on the weather conditions of your area.

Investing in the right kind of greenhouse plastic material will help you ave a lot of headache and pain in the long run as a small tear in the sheet can drastically affect the environment of the greenhouse.

Transparency and Light Efficiency

Greenhouse are no longer green, and green plastics are no longer used. In fact, in general practice, growers opt for good quality transparent plastics that have excellent light diffusion efficiency and transparency. After all, the main objective of the greenhouse is to provide ample sunshine and optimum warm temperature so that the plants can undergo photosynthesis and flourish in any weather.

While using fibreglass or glasshouse, transparency is not much of a bother. However, in the case of plastics, the situation can become tricky if the right kind of plastic is not used. Remember to opt for six mil polyethylene film with a light transmittance of more than 90 per cent. Since the high light transmission is essential for plants to thrive appropriately, it is crucial to choose the correct greenhouse plastic for with appropriate light transmission.

Light Diffusion

Plants make their own food, and for that, they not only need light but the light from all directions. This means to grow and flourish; plants need ample sunlight from all corners else they will end up in uneven growth.

The light diffusion capacity should be 20 per cent. Various plants, especially the taller ones or the self-shading ones, will grow unevenly if they have inappropriate exposure to sunlight. Thus, the greenhouse should have proper light diffusion that allows adequate lighting to all plants inside the structure. In the long run, a greenhouse plastic that gives proper light diffusion will help you get a fuller and even growth in all your plants in the greenhouse.

Thicker the Better?

No, certainly not! While thick plastics can be durable, but they can be heavy too. This means that they will offload their weight on the frame of the glasshouse. Since plastic sheet in itself does not have any structural integrity and support, it will fall heavily on the greenhouse frame.

Therefore, first of all, you need to put a sturdy glass frame and need to have an optimum balance of plastic sheet and frame to sustain your glasshouse for a more extended period.

Additional Properties of Plastics

  • Anti – Drip Property:

Since your greenhouse is built to keep the atrocities of weather at bay, you need to choose the plastic that can help it perform it to its optimum and help the plants feel safe and happy inside.

This means you have to think of the weather in your area. If you live in a cold-weather state where there is snow most of the times, you need to choose a plastic that has anti-drip properties. Don’t understand what it means? Let’s see it this way. The greenhouse weather inside will be naturally warm inside, and the weather will be extremely harsh and cold outside. This can lead to the formation of tiny droplets on the inside on the plastic, which will eventually fall on the plants making the inside atmosphere damp and soggy. This may hamper the plant growth ultimately.

It will not only disturb the plant ecosystem but will also lead to the growth of mould or mildew.

Therefore, you need to choose a plastic that has anti-drip properties. Some plastics are built with hydrophilic radicals or the – COOH. These are carboxylic acid compound that prevents condensed water droplets from dropping the plants. Droplets remain stuck to the plastic and get evaporated naturally back again.

It is important to note that while purchasing greenhouse plastic, you need to ask the vendor if it is made from hydrophilic or hydrophobic compounds like –CH groups. Hydrophobic compounds will repel the water droplets which will fall inside the greenhouse or on plants, thereby deteriorating the greenhouse environment eventually.

  • Anti-Dust Property Plastics:

Most plastics have a tendency to gather dust which means they tend to have reduced light diffusion property and light transparency. This will eventually lead to less light inside the greenhouse and will retard the plant growth as well as the entire Greenhouse ecosystem.

Some plastics tend to gather more dust than their contemporary products. So remember to ask your vendor about these properties and plastic material properties.

Plastic Materials:

Several plastic materials are available for building the greenhouse. You can choose from a variety of these materials depending upon your weather conditions and type of greenhouse you want to develop.

  • Polyethylene

This is one the industrial-grade where you can choose not to bother much about the weather. If you have ambient weather for growing plants in, you can opt for this kind of plastic.

It is cheap and can be bought online easily. It is not too heavy either as it is industrial grade and easy to repair. You can choose from the various category of polymers of polyethylene. While shopping for your greenhouse, look out for those labelled as ‘agriculture plastics’.

It is the right choice if you are short of money and would not mind tending to your plastic sheet at least once in a year for repairs etc. You may also have to replace it within a year or two. If you are ready to manage the repair and damage to your plastic sheet for the greenhouse, polyethylene plastic is a cheap and good choice to go for.

  • Polyvinyl Carbonate Sheets

They are the least used options for greenhouse plastics; nevertheless, they are an excellent choice due to their longevity. They usually last up to 5 years with least maintenance. However, their durability is accompanied by a price. They are often most expensive greenhouse plastic sheets and also available in shorter lengths. So if you are planning to build a large greenhouse, then you might as well drop this option.

  • Polycarbonate

They are one of the most favoured choices for greenhouse plastics. They are durable, tensile and come at a budget cost. Although they are more expensive than the polyethylene plastics, nevertheless, they are more rigid giving the required tensile strength and durability to the sheet.

Warranty and Guarantee Aspects

The plastic must come with at least four years warranty. After all, you will be spending a lot of money, time and energy in your greenhouse.

You can take a look at the local nearby stores that will give you six mil greenhouse plastics, but most of them are not UV stabilised. This means, within four months of purchase, you will end up with torn and brittle greenhouse plastic in your garden that will need replacement on an immediate basis.

Thus, it is vital to choose the right kind of plastic that is UV stabilised, and you do not need to replace it too often.
