Surprisingly enough, plants don’t always need light. In fact, some plants need a specific amount of darkness throughout the day to experience optimal growth. With that being said, not all plastic coverings are created equal. Choosing to cover your greenhouse with clear reinforced plastic can be great if you’re trying to reduce your crop’s exposure to harsh weather conditions, but is not ideal when you’re trying to minimize the amount of light that gets into your greenhouse. In this post, we will discuss two light-reducing plastic coverings that will work best for a greenhouse that is growing flowering plants.

Super 4 Greenhouse Plastic

While this type of plastic covering will not directly minimize UV exposure, it is designed in a way that allows for UV exposure to be distributed evenly. This allows for the pollination process to take place more effectively. Too much direct exposure to sunlight can cause your plants to not grow as efficiently, which is why Super 4 greenhouse plastic is the way to go if you’re looking for sunlight to be distributed evenly among all your plants.

Super 4 Greenhouse plastic also boasts a highly protective surface that is created during the manufacturing process using resin technology. This design ensures that a Super 4 plastic covering will be more durable to withstand extreme weather conditions. It is also highly resistant to tearing in critical areas. With advanced UV stabilizers built into the film, this covering can maximize the physical properties of your crops.

This film is not susceptible to chemical damage, which allows it to serve your greenhouse for a long time without having to be replaced. Overall, this type of plastic covering is a great alternative to your standard polyethylene plastic coverings because of its durability and UV resistance. Due to its chemical components, this film can withstand even the harshest conditions and is a great option for growers who are looking for a quality covering that can enhance the speed of their growth and quality of their yield.

Black and White Reinforced Light Deprivation Plastic Coverings

Now that we’ve gone over an all-inclusive durable option that will work well for most greenhouses, we’d like to discuss another type of plastic covering that is made specifically to limit the amount of light exposure your greenhouse gets throughout the growing season. This type of plastic covering is Pro-Tect’s Black and White Light Deprivation Plastic.

Black and white light deprivation plastic is ideal for plants that flower in the dark. If you’re waiting on your harvest to begin the flowering process for a longer time than you expected, it could be because you’re not properly controlling the amount of light that gets into your greenhouse. Flowering plants need a certain amount of darkness to bloom, and if your greenhouse doesn’t have the proper protection that can control the darkness of your grow operation, then you will find that your crop will not develop as intended. Thankfully, there are light deprivation solutions available that can help you achieve the results you want in your harvest.

While this type of plastic covering is specifically designed to keep light out, there are many types of plastic films that you will need to consider before you start the harvesting process. Super 4 plastic coverings create a durable layer that will protect your crops from the elements effectively but will do little in the way of controlling the darkness levels of your grow house. It is important to know these differences when choosing which type of film will work best for your operation.


Having given a brief overview of two different types of protective greenhouse coverings, it can’t be denied that some plastic coverings serve different functions. While both the options outlined above do a good job of evenly distributing sunlight, Super 4 coverings are best for their durability and protection against intense exposure to UV light. However, they do not allow you to control the darkness levels of your greenhouse. This can be a problem if you’re trying to grow flowering plants.

Light deprivation plastic, on the other hand, is specifically designed to control the darkness of your greenhouse allowing you to adapt to your crop’s needs. Many newer agricultural hobbyists don’t realize the importance of having the proper protective layer on your greenhouse to protect your crops from the elements.
