When it comes to enhancing the growth and productivity of plants in small greenhouses, one of the most critical factors is effective insulation and protection from the elements. For many gardeners and greenhouse enthusiasts, polythene covers have become a go-to solution. In this blog post, we’ll delve into the benefits of using polythene covers for small greenhouses and provide practical tips for selecting and maintaining them.
What Are Polythene Covers?
Polythene covers are made from polyethylene, a type of plastic that is widely used due to its durability and flexibility. These covers are designed to create a controlled environment for plants by regulating temperature, humidity, and light exposure. They come in various thicknesses and grades, allowing you to choose the best option based on your greenhouse needs.
Benefits of Polythene Covers
- Temperature Regulation
Polythene covers offer excellent insulation properties. They help to maintain a consistent temperature inside the greenhouse, protecting plants from extreme cold or heat. This is particularly beneficial during the winter months or in regions with fluctuating temperatures.

One of the significant advantages of polythene covers is their ability to transmit light effectively. This ensures that plants receive the optimal amount of sunlight for photosynthesis, promoting healthier growth. Most polythene covers allow up to 90% of natural light to pass through.

Compared to other greenhouse covering materials, polythene is relatively inexpensive. It offers a budget-friendly option for hobbyists and small-scale greenhouse operators who need a practical solution without breaking the bank.

Modern polythene covers are designed to withstand various environmental stresses, including UV radiation and high winds. They are also flexible and can be easily adjusted or replaced when needed. Find more information on the durability of greenhouse materials at Growers Supply.
Choosing the Right Polythene Cover
When selecting a polythene cover for your small greenhouse, consider the following factors:
- Thickness
Polythene covers come in different thicknesses, typically measured in microns. Thicker covers offer better insulation and durability but may be more expensive. For most small greenhouses, a thickness of 200-300 microns is sufficient. - UV Protection
Choose covers with UV stabilization to prevent degradation from sunlight. UV-resistant polythene will last longer and provide consistent performance throughout the year. Read about UV protection in greenhouse covers on The Greenhouse People. - Ease of Installation
Ensure that the polythene cover you choose is easy to install and fits your greenhouse structure well. Some covers come with pre-installed grommets or fastening systems for convenience. Find installation tips and guides at B&Q.
Maintaining Polythene Covers
Proper maintenance is key to extending the life of your polythene covers. Regularly inspect the covers for any signs of damage, such as tears or punctures. Clean the covers periodically to remove dirt and debris that can obstruct light transmission. Ensure proper ventilation to prevent overheating and humidity build-up inside the greenhouse.
