Choosing the Right Plastic for Greenhouses

Putting up a greenhouse is a great idea for anyone who enjoys gardening. This is more so if you are looking to carry out your gardening activities across all four seasons.

The use of plastic for greenhouses is the cheaper alternative for your backyard gardening when compared to using glass. A small sized greenhouse in your backyard may be all you need to ensure your very own healthy supply of organic fruits and vegetables.

Various Sizes
You will find plastic for greenhouse kits of many sizes available for purchase. If you are looking to construct your own green house from scratch, you may want to check for different greenhouse plans and layouts. The Internet has a wealth of information that you can implement when constructing your own greenhouse. Depending on the size you require, you can have one ready in just one or two days.

Energy Efficient
Apart from being cheaper than glass, using plastic for greenhouses is more energy efficient than glass. It has been found that using plastic for your green house can add up to six weeks to the length of your growing season. Greenhouse plastic captures more light than glass and traps the heat to provide solar heating. This ensures that the temperatures inside stays warmer for longer. In addition, the soil also stays warmer for longer which in turn allows your crops more growth time.

Lights and Heat Lamps
It is quite possible to become a four season gardener by growing your plants in a purpose-built green house. You can put additional lighting in to improve the heat conditions for your plants, especially during the dark and cold winter months. For a longer growing season, you may want to start your growing season in the early growing months.

Features of Greenhouse Plastic
The plastic for greenhouses is specially designed in a knitted form which makes it capable of withstanding heavy duty handling. Its durability means that it can be cut in to various shapes and sizes without ripping or fraying.

The other unique feature of greenhouse plastic is that it filters ultraviolet rays from the sun unlike conventional plastic sheeting.

The lightweight nature of greenhouse plastic sheeting makes it the preferred covering for most users. Primarily this is because plastic does not require heavy duty structural frames for construction. This also makes it easy to handle, and any gardener who wishes can put it up without much difficulty.

Types of Plastic for Greenhouses

There are many types of plastic for greenhouses available on the market. However, the three most commonly used types of greenhouse plastic are:

  • Polyvinylchloride (PVC)
  • Polyethylene (PE)
  • Copolymers

Both PVC and PE types are less durable than copolymers, lasting for a year or two respectively. The commercial variation of PE can also be specially treated to filter out ultra violet rays. Copolymer on the other hand, can last up to five years and does not require regular cleaning to clear off dust build up like the first two. This is because copolymer has been designed to imitate the characteristics of glass, although you will find that it does not cost as much as glass.
