When it comes to shading a greenhouse, there are various options available, but one of the most common and cost-effective methods is using polyethylene mesh or netting, also known as shade netting. This type of shading is typically installed inside the greenhouse and secured with clips. While external fitting is generally more effective, it can be more challenging to arrange.
Polyethylene mesh or netting provides an affordable alternative to other shading options such as blinds. It is a lightweight material that allows some light to penetrate while providing shade and reducing the intensity of sunlight. This is particularly beneficial during hot summer months when excessive heat can damage plants.
One advantage of using shade netting is its relatively low cost. Although the plastic material will biodegrade over time, it is not expensive to replace. This means that you can easily replace the netting as needed, ensuring that your greenhouse remains adequately shaded without breaking the bank.
Personal Experience: In my own greenhouse, I have found shade netting to be a practical and budget-friendly solution for shading. I initially tried using blinds, but they were quite expensive and required more maintenance. Switching to shade netting was a game-changer as it provided sufficient shade while still allowing enough light for my plants to thrive.
When considering shade netting for your greenhouse, it is important to choose the appropriate density or percentage of shading. Shade netting is available in various densities, typically ranging from 30% to 90%. The percentage indicates the amount of sunlight that will be blocked by the netting. The choice of density depends on the specific needs of your plants and the climate in which you are located.
In regions with intense sunlight or during the summer, a higher percentage of shading, such as 70% or 90%, may be necessary to prevent overheating and sunburn on delicate plants. Conversely, in cooler climates or during the winter months, a lower percentage of shading, such as 30% or 50%, might be more suitable to allow for adequate light penetration.
Installation of shade netting is relatively straightforward. The netting can be attached to the greenhouse structure using clips or hooks. It is important to ensure a secure and tight fit so that the netting does not sag or blow away in strong winds.
One consideration to keep in mind is that shade netting may reduce air circulation within the greenhouse. To mitigate this, it is advisable to provide additional ventilation by using fans or vents. This will help maintain a healthy environment for your plants by preventing the buildup of excess heat and humidity.
Using polyethylene mesh or netting as shade netting is an effective and affordable way to shade a greenhouse. It provides protection from excessive sunlight while allowing some light to penetrate. The netting is easy to install and replace, and the choice of shading density can be tailored to the specific needs of your plants and climate. By ensuring proper ventilation, you can create an optimal growing environment for your greenhouse plants.
